Bateu — repasse shortfall catcher for Wellhub partner gyms

1. One-liner

Matches every Wellhub and TotalPass check-in to what your gym was paid and files the objection inside 7 days.

2. Trend signal — why now?

Brazil’s two corporate-fitness aggregators pay roughly 70,000 partner gyms and studios per check-in, on a statement the partner sees after the fact, under a contract that deems the statement accepted if nobody objects within seven days. In the last ten months both platforms cut per-visit rates, one signed a competition-authority agreement that leaves 40,000 partners negotiating alone, and the bigger one started charging 1.49% to pay weekly. Every one of those moves makes the monthly statement worth checking. Nobody sells the check.

The contract clause. Wellhub’s Brazilian partner terms (BR-GYM-v.May2024, clause 4.3) say the monthly Pagamento Total lands by the 15th, and then: “Caso o Parceiro questione o número total de validações que serão pagas pelo Wellhub durante um determinado mês, o Parceiro notificará o Wellhub, incluindo evidências e detalhes específicos, no prazo máximo de 7 (sete) dias após a recepção pelo Parceiro do Pagamento Total para referido mês. Caso o Parceiro não se manifeste no prazo de 7 dias, considera-se que o Parceiro aceitou o número total de validações referentes àquele mês.” Seven days, evidence required, silence is acceptance.

The statement is not one number. Wellhub’s own partner help centre lists what a repasse is built from: the base “Pagamento por Check-in”, a possible “Primeira Visita Grátis” for new visitors, a “Pagamento Máximo por Visitante” monthly ceiling after which further check-ins show as R$ 0,00, “pagamentos parciais por Faltas (No-Shows) e Cancelamentos Tardios”, a “comissão de Taxa de aumento de resultado” (success fee), and “dedução de Adiantamento” (cash-advance recovery). Each product a gym offers can carry its own rate and cap. The portal gives two downloadable reports, “Pagamento por visitante” and “Detalhes de check-ins” (“incluindo data, hora, pagamento por check-in e serviço utilizado”), and a payment history. It does not give a diff against what the contract says should have been paid.

The rates are moving down, in writing. A São Paulo studio owner posted on Reclame Aqui on 13 November 2025 that TotalPass notified a cut with three mandatory options: R$ 24,75 per visit down to R$ 16,42 (with the monthly cap raised from 12 to 14 visits), or R$ 20,17 (cap kept at 12), or a downgrade from tier TP3 to TP4. Their reply to the company: every option meant “impacto negativo e prejuízo financeiro considerável”. Correio (Salvador) ran the same story on 20 February 2026 with an anonymous owner: the old model paid R$ 224 per student at 14+ check-ins, the new one R$ 196 capped at 14 regardless of use. Quote: “Em resumo, o aluno paga mais caro e a gente recebe menos.” And: “Se a gente não aceita as mudanças, perde o convênio.” TotalPass did not respond to the paper.

Wellhub side, same shape. A Taubaté pilates studio (Reclame Aqui, 18 March 2025): Wellhub emailed her students that the studio would migrate from Silver to Silver+, raising what students pay, “o meu repasse irá continuar o mesmo, sem ter reajuste algum.” Wellhub’s answer offered her the choice to opt out or be auto-upgraded on 1 April. A Goiânia user on 19 March 2026 filed against Wellhub because their gym had restricted access after a “redução significativa nos valores de repasse às academias parceiras”; Wellhub’s reply stated that “as condições comerciais entre o Wellhub e seus parceiros são protegidas por cláusulas de sigilo.” Multiple Reclame Aqui threads in March and April 2026 report gyms capping Standard-plan users at 12 or 13 check-ins a month “para minimizar perdas”. An older partner complaint, still the clearest description of the mechanic, reports R$ 28,93 per class, an October report with “valores zerados”, and the line “oferecemos o serviço, tivemos as custas pela prestação do serviço e não recebemos por uma quantidade razoável de aulas dadas.” Another partner: incorrect amounts three months running, corrections taking 60+ days, a cap of 8 paid classes rising to 10 at roughly half the daily rate while the user’s pass is unlimited.

The platform is now monetising partner cash flow. Seu Dinheiro, 18 August 2026: Wellhub launched weekly payouts for eligible partners at a 1.49% fee, an insurance line with Avla (R$ 54,58 to R$ 195,90 a month), and disclosed R$ 100 million+ of credit issued to 1,000+ gyms since August 2025 with about a third of active partners holding pre-approved lines at an average ticket of R$ 130,000. A partner base that borrows from the platform, pays to be paid faster and insures through it is a partner base with thin margins and a statement it cannot afford to get wrong.

The competition deal. Wellhub’s 15 January 2026 agreement with CADE caps exclusivity at ten chains (about 1,700 units) and states that its roughly 40,000 non-exclusive Brazilian partners negotiate “sem qualquer expectativa de exclusividade”. Those 40,000 are on their own on rates and caps.

Scale. Wellhub reports nearly 45,000 partners in Brazil across 2,100 cities, including 37,000+ independent gyms and studios; the group is at $319M ARR on a $2.4B valuation, passed one billion check-ins in 2025 and says payouts to partners grew 107% globally last year. TotalPass (Smart Fit) reported 2.1 million clients and 34,000+ partner gyms and studios in Brazil in Q1 2026. Brazil has 41,332 active gyms per the HFA 2025 Global Report; Fitness Brasil’s Panorama Setorial 2025 counts 56,000+.

Incumbent check. Tecnofit (16,500 gym clients) ships a Wellhub dashboard with “faturamento estimado”, average ticket and the number of check-ins needed to reach maximum payment: the gym’s own estimate, not the platform’s statement. Next Fit’s help article on its Wellhub reports says the financial columns are empty unless “se faz necessário a importação da planilha disponibilizada na plataforma do Wellhub”, i.e. the owner downloads and imports the spreadsheet by hand. Pacto and CrossX document the check-in integration and the payout formula (“até 90% do valor anual praticado em balcão… dividido por 12”, “Comissão máxima” at 12 visits) and stop there. ClassPass in the US publishes a partner ledger with an audit trail. No Brazilian product reconciles the statement to the contract, names the shortfall, and files the objection.

Provenance:

3. The opportunity

This is the “fine automatic, refund manual” shape with the sign flipped. The platform computes the payout, applies caps, first-visit exemptions, no-show partials, success-fee commissions and advance deductions, and hands the partner a total on the 15th. The contract gives the partner seven days to object with evidence or accept forever. The partner’s tools stop one step short: the gym software shows what the gym thinks it earned, the portal shows what Wellhub decided to pay, and the owner has a week, a WhatsApp support line, and no diff.

Bateu is the diff, with the objection attached. It ingests the two portal reports and the payment history, the gym’s own validated check-in log from its management system (Tecnofit, Next Fit, Pacto, CrossX, EVO all record every Wellhub validation), and the gym’s contract terms as the owner enters them once. For every check-in that paid less than the base rate it assigns a cause: monthly cap hit for this visitor, first-visit-free, no-show partial, success-fee deduction, advance recovery, product priced differently, check-in never validated, or unexplained. The unexplained pile is the shortfall. It totals it, drafts the objection in the exact form clause 4.3 requires (evidence, specifics, inside seven days), and tracks whether the correction lands on the next statement or takes the 60 days one complainant described.

The second thing it does is the thing the platforms’ confidentiality clauses prevent owners from doing for themselves: it shows what each aggregator visitor is actually worth. A Wellhub Silver+ subscriber pays Wellhub R$ 199,99 a month; if that person checks in 14 times at a studio whose rate is R$ 16,42 with a 12-visit cap, the studio gets R$ 197,04 and knows it, but only if someone did the arithmetic on that visitor. Bateu does it for every visitor every month, flags members who moved from a direct plan to the aggregator, and produces the one memo the owner actually needs before the next rate-cut email: what a cap of 12 would cost, what dropping the platform would cost, and what the three offered options are worth in reais on last quarter’s real usage.

The incumbents cannot do this. Wellhub and TotalPass are the counterparty and hold the terms under NDA. The gym software vendors integrate the check-in and, in Next Fit’s case, explicitly ask the owner to import the spreadsheet themselves. ClassPass built the ledger for its studios; the Brazilian platforms built the dashboard and the deadline.

4. Target market

  • Primary customer: the owner or manager of an independent gym, crossfit box, or pilates/yoga/functional studio in Brazil with 40 to 400 aggregator check-ins a month from Wellhub, TotalPass or both, on a per-check-in contract with a monthly cap. Pilates and small studios are the loudest because their per-class cost is highest and the R$ 16–29 rates hurt most. Multi-unit operators with three to fifteen units are the second segment; they have the same problem times N and a finance person who already opens the spreadsheet.
  • Why they buy: “não recebemos por uma quantidade razoável de aulas dadas”; “valores zerados”; “repasse abaixo do combinado há três meses e a correção leva mais de 60 dias”; “se a gente não aceita as mudanças, perde o convênio.” They cannot tell contract from error, they miss the seven-day window, and when the rate-cut email arrives they decide on gut.
  • Rough TAM reasoning: Wellhub says 37,000+ independent gyms and studios in Brazil; TotalPass says 34,000+ partners; the overlap is large. Call it 45,000 unique partners. If a third have enough aggregator volume for the monthly statement to matter (roughly 15,000) and a fifth of those will pay for a tool that pays for itself on one caught shortfall, the serviceable market is about 3,000 paying gyms in Brazil at launch pricing. Enough for a solo business, not a fund.
  • Why now for them: rates are being cut with 15-day notices and take-it-or-lose-the-convênio options, the platform now charges to pay weekly and lends against future repasse, and every month that goes unobjected is a month accepted under clause 4.3.

5. Product sketch (MVP)

  • Connect in five minutes: upload the portal’s “Detalhes de check-ins” and “Pagamento por visitante” exports plus the payment PDF; connect the gym’s management-system export (Tecnofit, Next Fit, Pacto, CrossX, EVO) or paste its check-in report; enter the contract once: rate per product, cap, first-visit rule, no-show rule, success fee, any advance.
  • The diff: every check-in in one table with what the gym validated, what the platform paid, and the cause. Unexplained shortfall totalled at the top in reais. Runs for Wellhub and TotalPass side by side.
  • The seven-day clock: statement date detected, objection deadline shown, WhatsApp reminders at day 3 and day 6.
  • The objection, drafted: a Portuguese notification citing clause 4.3 with the visitor list, dates, expected versus paid, and the gym’s own validation log attached as evidence; one click to copy into the partner support channel; a log of what was objected, when, and whether the correction appeared on the next statement.
  • Visitor economics: per aggregator visitor per month, what the platform charged them (tier price is public), what the gym received, and the cap that binds. Members who cancelled a direct plan and reappeared via the aggregator are flagged with the monthly revenue delta.
  • The rate-cut memo: paste the platform’s options (R$ 16,42 at 14, R$ 20,17 at 12, or a tier downgrade) and get each priced on the last three months of real check-ins, alongside “cap at 12” and “leave”.
  • Monthly WhatsApp summary on the 16th: shortfall found, objection ready, visitor value, cap recommendation.

6. AI angle — what’s load-bearing

Three pieces, and the arithmetic is not one of them.

Parsing. Two platforms, five gym management systems, exports that change columns without notice, payment PDFs with deductions described in prose. A model reads whatever the owner uploads and maps it to check-in, visitor, product, amount, deduction type. Without this the product is a template that breaks the first time Wellhub renames a column.

Cause assignment. Deciding whether a R$ 0,00 line is a cap, a first visit, an unvalidated check-in or an error requires holding the contract terms, the visitor’s history that month and the product’s rules together. That is a rules-plus-judgement task; the model proposes the cause with a confidence and the owner confirms the ambiguous ones, which is how the rules library for each contract shape gets built.

The objection and the memo. Clause 4.3 wants “evidências e detalhes específicos”. The model writes the notification in the platform’s own vocabulary with the evidence attached, and writes the rate-cut memo as a narrative an owner can forward to a partner or an accountant. This is the underwriter-narrative gap seen elsewhere: the number is easy, the argument is the product.

Remove the AI and you have a spreadsheet the owner has to maintain themselves, which is exactly what Next Fit already tells them to do.

7. Localization angle (if any)

Brazil-first by design, not as a translation.

  • Language: Portuguese UI, Portuguese objection text, WhatsApp as the delivery surface because that is where the owner reads the platform’s support replies.
  • Payment rails: Pix monthly; Pix Automático once the gym’s bank supports it. No card requirement.
  • Pricing: R$ 149 to R$ 399 a month. A R$ 49 tier would sell but not survive support; the product pays for itself on one caught shortfall at R$ 16,42 times ten check-ins.
  • Contract quirks: the seven-day clause, the per-product rate and cap structure, the success fee and advance deductions are specific to the Wellhub BR terms; TotalPass has its own tiers (TP1–TP4) and caps (12/14). The rule library is the localisation.
  • Second market: TotalPass and Wellhub both operate in Mexico; same statement, Spanish, a year later. The US (ClassPass) already has a partner ledger and is a weaker fit.

8. Business model — path to $1M–$5M ARR

  • Pricing: R$ 149/month for one unit and one aggregator; R$ 249/month for one unit with both aggregators and the rate-cut memo; R$ 399/month per unit for multi-unit operators with a roll-up view. Annual at ten months.
  • ACV: roughly R$ 2,400 a year blended, about $430 at current rates.
  • Rough math to $1M ARR: about 2,300 paying gyms at R$ 199 average. That is 15% of the serviceable 15,000, which is aggressive for a single-country tool sold to owners who run on WhatsApp. $500K ARR at 1,150 gyms is the honest 18-month target and a very good solo-founder business.
  • Rough math to $5M ARR: not on Brazilian independents alone. Needs Mexico (both platforms present), the multi-unit tier at R$ 399 per unit across the 100–500-unit regional chains that are not in Wellhub’s exclusive ten, and an accountant tier where the firms advertising “contabilidade para academias” run twenty clients’ statements a month. Year-two decisions.
  • Expansion path: per-unit pricing; the accountant/agency roll-up; a benchmark tier once enough anonymised, opt-in contract data exists to tell an owner where their R$ 16,42 sits against studios of the same type in the same city, which is precisely what the platforms’ confidentiality clauses stop owners from learning by asking each other.

9. Go-to-market wedge — first 100 customers

  • The complainants, by name. Reclame Aqui’s Wellhub and TotalPass pages carry partner complaints with city and, usually, the studio’s name in the text or the reply. Search “repasse”, “parceira”, “check-ins” across both companies, build a list of 150 owners from 2024–2026, find each studio on Instagram, and DM: “Você tem 7 dias depois do repasse para contestar. Me manda o extrato de agosto e eu te mostro o que ficou zerado.” Expect 40 replies, 15 statements, 8 paying.
  • “Bateu?” on the 16th. The day after each monthly repasse, post a one-page free check in the gym-owner Facebook and WhatsApp groups and on Instagram: upload the two portal reports, get the zeroed and short check-ins classified in sixty seconds, no account needed. Convert the “how do I get this every month with the objection ready” replies. Timed content aimed at a known date, not evergreen SEO.
  • The gym software vendors’ own gap. Next Fit tells its users to import Wellhub’s spreadsheet by hand; Tecnofit shows an estimate. Pitch Next Fit, Pacto and CrossX a referral or embedded tab: “your customers already ask you why the repasse doesn’t match; send them to us.” One vendor with a few thousand gyms is worth more than any ad budget.
  • Pilates and studio communities. The angriest quotes are pilates studio owners at R$ 16–29 a class. Target the studio-format Instagram hashtags by city (#pilatesstudio + São Paulo, Curitiba, Belo Horizonte, Salvador) and the studio-owner mentorship communities such as Escola Gestão Fitness, where the founder already sells management courses to this exact owner; offer the free check as a workshop.
  • Accountants for gyms. The firms that advertise “contabilidade para academias” reconcile these statements for their clients today, badly, in Excel. Offer five of them a white-label roll-up at a flat fee; five firms at ten clients each is fifty accounts and a channel that compounds.

10. Build complexity — justification

Low. Inputs are CSV/XLSX exports the owner already downloads plus a payment PDF; parsing is a model call with a fixed output schema. The diff is deterministic once the contract is entered. Objection drafting and the rate-cut memo are prompt-and-template work. WhatsApp delivery via the Business API, Pix billing via any Brazilian PSP. No platform API is required, which matters because the Wellhub partner terms restrict how partner data is used and the portal has no partner-facing payout API. A solo builder ships the Wellhub-only version in six weeks; TotalPass and the multi-unit roll-up add four more. The genuine work is the rules library for each contract shape, which grows from the first fifty statements.

11. Gating checklist

GatePass?Note
Legal in target market✅The gym uploads its own reports and its own contract terms; no scraping of the partner portal, no use of subscriber personal data beyond the gym’s own records. Benchmarking must be anonymised and opt-in given the confidentiality clause in the partner terms.
Ethical — no harm / dark patterns✅Helps a partner exercise a contractual right within the window the platform wrote. Objections are evidence-based.
Market exists (evidence above)✅Dated complaints from named partners on both platforms, press coverage of rate cuts, platform financial products aimed at partner cash flow.
1–5 person team can build this✅Solo to pair; six to ten weeks.
Launchable with <$50K / ₹40L✅Under R$ 40,000 including three months of the founder’s time and WhatsApp API costs.

12. Feasibility score

AxisWeightScoreNotes
Problem intensity2014/20Money leaks monthly and the contract forfeits it after seven days; owners describe losses in writing and cap access to stop the bleed. Not hair-on-fire for a gym with 30 aggregator check-ins; very real for a studio at R$ 16 a class with 300.
Demand evidence1510/15Dated partner complaints on both platforms, a regional newspaper story, platform actions that price partner cash-flow stress, and a gym-software vendor documenting the manual workaround. No one yet pays for reconciliation specifically, and Reclame Aqui volume from partners is dozens, not thousands.
Build feasibility1512/15Uploads, a model parse, a deterministic diff, a drafted letter, WhatsApp. Six weeks solo. Export formats will drift.
Distribution clarity1510/15Named complainants, a dated monthly hook, two vendor gaps to sell into, pilates communities and gym accountants. Conversion from WhatsApp-run owners is the uncertainty.
Revenue mechanics158/15R$ 149–399 is right for the wallet and pays back on one caught shortfall; ACV ~$430 means 2,300 customers for $1M, which is a lot of Brazilian studio owners for one product. $500K is the realistic mark.
Time to first revenue107/10Free check on the 16th converts inside the same seven-day window it advertises. First paying gym in weeks four to eight.
Defensibility105/10Execution moat at month three. By month twelve the contract-rule library and the anonymised rate benchmark are things neither the platforms (conflicted) nor the gym software vendors (integration partners of the platforms) will build. Copyable by a motivated competitor with the same fifty statements.

13. Qualitative modifiers

Founder-fit tags

technical-heavy · sales-heavy. A Portuguese-speaking builder who will personally read fifty statements and sit on WhatsApp with studio owners for the first quarter. Domain expertise is acquired from the statements themselves.

Key assumptions to validate (3–5)

  1. Assumption: at least one in four aggregator statements contains an unexplained shortfall above R$ 200 once contract causes are removed. How to test: collect 40 real statement pairs (portal reports plus gym check-in log) from complainants and community volunteers; classify by hand; count.
  2. Assumption: objections filed with evidence inside seven days actually get corrected on a following statement. How to test: file ten on behalf of pilot gyms and track correction time; if the median exceeds 60 days or corrections do not appear, the product is a record rather than a recovery and pricing must drop.
  3. Assumption: owners will pay R$ 149–249 a month for this rather than expecting it from Tecnofit or Next Fit. How to test: offer the paid tier to the first 30 free-check users the same day; target 8 conversions.
  4. Assumption: portal exports and payment PDFs are stable enough that a model parse holds across months and across the two platforms. How to test: run the parser on statements from three different months and both platforms before launch.
  5. Assumption: the rate-cut memo changes decisions. How to test: give it to five owners who received a 2026 cut notice and ask which option they chose before and after.

Risk flags

  1. Platform dependency: everything runs off exports the platforms control. A portal redesign breaks intake for a month; a partner-portal feature that shows the diff removes the core. Wellhub has shipped credit, insurance and weekly payouts for partners in twelve months and could ship a reconciliation view next.
  2. Contractual/legal: the partner terms carry confidentiality and data-use clauses. Benchmarking rates across gyms must be anonymised, aggregated and opt-in, and the product must never touch subscriber personal data beyond what the gym already holds.
  3. Small ACV, WhatsApp-run buyers: studio owners churn when the shortfall is zero for two months. Retention depends on the visitor-economics and rate-cut memo being read even when nothing is owed.
  4. Market timing: if the 2025–2026 rate cuts settle and platforms stop repricing, the emotional trigger fades; the seven-day clause and the caps remain, so the product survives but converts slower.

14. Structured verdict

Score:                  66/100
Verdict:                VALIDATE
Confidence:             Medium
Best-fit builder:       Portuguese-speaking technical founder willing to do 90 days of

Time to revenue:        4–8 weeks

Top 3 assumptions to validate first:
  1. Shortfall frequency — hand-classify 40 real statement pairs; need >25% with
     an unexplained shortfall above R$ 200
  2. Objections get paid — file 10 within the 7-day window for pilot gyms;
     need a median correction inside 45 days
  3. Willingness to pay — convert 8 of the first 30 free-check users to R$ 149–249
Kill criteria:
  - Abandon if fewer than 5 of 40 statements show an unexplained shortfall above R$ 200
  - Abandon if Wellhub or TotalPass ships a statement-vs-contract diff with an
    objection flow in the partner portal before v1
  - Abandon if fewer than 5 of the first 30 free-check users pay within 30 days

15. Next step — 1-week validation sprint

  • Day 1–2: build the list. Pull every partner-side complaint mentioning repasse, parceira or check-ins from the Wellhub and TotalPass pages on Reclame Aqui (2024–2026), find the studios on Instagram, DM 100 with the seven-day line and an offer to check last month’s statement for free. Separately, download the Wellhub partner terms and write the cause taxonomy from clause 4 and the help-centre list of repasse components.
  • Day 3–4: hand-reconcile every statement that arrives (target 20). For each, classify every sub-rate line as cap, first visit, no-show partial, success fee, advance, unvalidated, product mismatch or unexplained. Send each owner a one-page result and, where there is a shortfall, the drafted objection. Ask each one: would you pay R$ 149 a month for this on the 16th of every month?
  • Day 5: decide. Go if at least 5 of 20 statements had an unexplained shortfall above R$ 200 and at least 5 owners said yes to R$ 149. Anything less and the leak is smaller than the complaints suggest, which is a finding worth having before writing a line of code.
