ShopSift — RFQ intake desk for small machine shops

1. One-liner

Reads every messy RFQ — PDF, photo, email — and hands a small machine shop a ranked worklist of what’s actually worth quoting.

2. Trend signal — why now?

Three things converged in the last 12–18 months.

First, the pain got loud. “Overwhelming RFQ Backlog — Strategies on Being Selective & Bidding Quickly” is a literal thread title on Practical Machinist, the largest machine-shop forum. Owners are openly trading hacks for triaging an inbox they can’t keep up with — A-list/B-list/trash sorting, tire-kicker smoke-tests, “quote the high-margin stuff first then work down the list.” This is a manual ritual today, run on gut and a folder of quote numbers.

Second, the math is brutal and now quantified by people in the trade. A shop processing 40 RFQs/week spends 80–120 hours on intake alone — 2–3 full-time bodies “doing nothing but reading emails and typing data into spreadsheets” (Approved Sheet Metal / Lumari). At the same time the win rate on cold price-shoppers is ~20%, so most of that intake labor is spent on jobs that were never going to land.

Third — the unlock — vision-language models now read engineering drawings, GD&T, and messy scanned PDFs / phone photos / inline email text. There’s active 2024–2025 research fine-tuning VLMs (and benchmarking GPT-4o and Claude) on drawing extraction. Crucially, ~40% of RFQs arrive with no clean CAD file — napkin sketches, marked-up PDFs, photos of a broken part. That fact kills naive “upload your STEP file” quoting tools. It’s exactly what a VLM-first intake reader is good at.

Provenance:

3. The opportunity

The whole quoting-software category is aimed at the wrong moment. Paperless Parts, Machine Research, KipwareQTE, Fulcrum — they all help you compute a price once you’ve decided to quote. But the small shop’s bottleneck is upstream: deciding which of the 40 things in the inbox are even worth opening, and getting the relevant numbers off a scanned drawing without re-keying them by hand.

Incumbents are mid/large-shop tools. Forum owners call Paperless Parts “a solution in search of a problem” for their size and say it’s “targeted to shops where quoting takes one or more full-time employees.” The cheap tools (KipwareQTE at $495 perpetual, shopVOX ~$99–199/mo) are dumb spreadsheets-with-a-UI — they don’t read the inbound mess and they don’t triage.

The 10× wedge: a focused intake desk that (a) ingests the RFQ in whatever format it arrives, (b) extracts part name, qty, material, key dims/tolerances, due date, (c) scores each against the shop’s own win-history and capability (“you’re 5-axis aluminum, low-volume; this is a 10k-unit screw-machine job → decline”), and (d) ranks the queue by likely-profit-and-winnable. Not a quoting engine. A pre-quoting filter that turns a chaotic inbox into a one-screen worklist.

4. Target market

  • Primary customer: Owner/estimator at a US CNC or job shop with 1–10 employees, <$2.5M annual revenue (the majority of the ~16,600 US machine shops fall here per SICCODE/IBISWorld). The person doing intake is usually the owner, after hours.
  • Why they buy: “I’m drowning in RFQs and I quote at night.” “Most of what comes in is price-shoppers and tire-kickers, but I can’t tell which until I’ve burned an hour.” “Customers send me a photo of a part and a one-line email.” They’re not asking for a better quote calculator — they’re asking to stop wasting evenings on jobs that were never real.
  • Rough TAM reasoning: ~16,600 US machine shops; majority sub-$2.5M/sub-20-employees. Even a serviceable slice of 8,000–10,000 small shops at $200–400/mo is a $20M–$40M ceiling — comfortably a sub-$5M-ARR bootstrap target with room.
  • Why now for them: RFQ volume is up (reshoring, more shops listed on Thomasnet/Xometry/MFG.com pulling in cold inbound), the labor to handle it is the scarcest thing in the shop, and the AI to read the mess just became good enough.

5. Product sketch (MVP)

  • Forward your RFQ email (or connect the shop inbox) — ShopSift reads the body, attachments, scanned PDFs, and phone photos.
  • Structured part card per RFQ: part name, quantity, material, headline dimensions/tolerances, finish, due date — extracted, with low-confidence fields flagged for a 5-second human check.
  • Capability fit check: flags jobs outside the shop’s machines/envelope/volume sweet-spot (configured once at onboarding).
  • Winnability + priority score: ranks the queue using the shop’s own quoted/won history (existing customer? repeat part? price-shopper pattern?).
  • One-screen worklist: “Quote first / Quote if time / Decline” buckets, sortable by estimated margin.
  • Tire-kicker flag on cold senders with no order history and price-only language.
  • One-click polite decline template for the no-quote pile (so relationships don’t silently rot).
  • Export the clean structured part data into whatever they price with (their spreadsheet, KipwareQTE, etc.) — explicitly not trying to replace their pricing step.

6. AI angle — what’s load-bearing

Remove the AI and there is no product. The core is a vision-language model reading unstructured, low-quality inputs — scanned drawings, marked-up PDFs, photos, free-text emails — and emitting structured, confidence-scored part data. That’s the thing no spreadsheet tool does and the thing the 40%-no-CAD reality demands. The second AI job is the ranking/triage judgment over the shop’s own history. Both are squarely in current model capability and neither is a research project.

7. Localization angle (if any)

N/A — this is a US-first play. The wedge is the English-language RFQ inbox of US small shops, where reshoring is driving inbound volume and where Thomasnet/MFG.com/Xometry are the lead surfaces. A later EU/India cut is plausible (the intake pain is universal) but adds no wedge today, and US shops have the clearest willingness-to-pay in dollars.

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

  • Pricing: $199/mo (Solo, 1 inbox, ~100 RFQs/mo) and $399/mo (Shop, multiple inboxes/seats, higher volume, capability profiles per machine cell). Annual discount. Deliberately above the dumb $99 tools, far below opaque enterprise.
  • ACV: ~$3,000 blended.
  • Math to $1M ARR: ~330 shops at ~$250/mo avg × 12. Out of ~8,000+ serviceable small shops, that’s <5% penetration.
  • Math to $5M ARR: ~1,400 shops, or hold customer count and expand ACV via per-cell capability profiles and a usage tier for high-RFQ shops, plus an upsell into lightweight quote-tracking (the other thing forums beg for).
  • Expansion path: start as triage → add quote-status tracking → add the actual price assist last (where the money and stickiness compound), walking up into the territory Machine Research/Paperless occupy, from a beachhead they ignore.

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

  • Practical Machinist, surgically. The exact threads exist (“Overwhelming RFQ Backlog,” “Quote Tracking,” “What percentage of quotes do you win?”). Show up with a genuinely useful intake teardown of a sample RFQ, not a pitch. The owners in those threads ARE the first 100.
  • r/Machinists (274k), r/CNC (119k), r/machining (33k). Post a “I built a thing that reads your RFQ pile and tells you what to quote” demo video; the no-CAD/photo reading is the hook that proves it’s not vaporware.
  • Cold, targeted, video-first. Pull small shops off Thomasnet/MFG.com listings, send a 60-second Loom that ingests their own publicly-listed capabilities and a sample drawing into a ranked worklist. Personalized demo > generic email. Expect low-single-digit reply, high demo-to-trial.
  • CNCCookbook / Modern Machine Shop / Production Machining — these outlets run owner surveys on exactly this pain and have the readership; a guest teardown or sponsored “RFQ triage” piece converts.
  • NTMA / PMPA member communities — small precision shops, peer networks; one champion shop → referrals.

10. Build complexity — justification

Medium. The intake reader is off-the-shelf VLM API plus a hardening layer for low-quality scans/photos and confidence scoring — the gnarly part is reliability on garbage inputs, not novel ML. Triage ranking is straightforward over the shop’s own history. Inbox connection (email forwarding first, OAuth later) and a clean worklist UI are standard web work. A pair ships a credible v1 in ~3–4 months; the risk is extraction accuracy on the worst 20% of inputs, which is an iteration problem, not a research one.

11. Gating checklist

GatePass?Note
Legal in target market✅Reading the shop’s own inbound docs; no regulated data.
Ethical — no harm / dark patterns✅Helps owners reclaim time; polite-decline feature protects relationships.
Market exists (evidence above)✅Named forum threads, quantified intake labor, funded adjacents.
1–5 person team can build this✅VLM API + web app; ~3–4 months.
Launchable with <$50K / ₹40L✅Inference + hosting + founder time; well under cap.

All five pass.

13. Qualitative modifiers

Founder-fit tags

technical-heavy · domain-expertise-required

A builder who can get VLM extraction reliable on bad scans, paired with (or who is) someone who has lived the machine-shop RFQ inbox. Domain credibility is what gets you taken seriously in those forums.

Key assumptions to validate (3–5)

  1. Assumption: Small shops will pay $200–400/mo to triage RFQs, separate from pricing them. How to test: 30 owner interviews from the named PM threads + a fake-door pricing page; look for ≥1/3 saying “yes, the inbox is the problem, not the calculator.”
  2. Assumption: VLM extraction hits usable accuracy on the messy 40% (photos, marked-up PDFs). How to test: Collect 100 real anonymized RFQs, run extraction, measure field-level accuracy and human-correction time. Target <30s correction per RFQ.
  3. Assumption: Triage ranking beats the owner’s gut enough to be worth keeping. How to test: Backtest ranking against a shop’s last 6 months of quoted-vs-won; did “Quote first” correlate with actual wins?
  4. Assumption: This subset (drowning shops) is large enough. How to test: Census CBP NAICS 332710 small-shop counts + survey on RFQ volume distribution.

Risk flags

  1. Competitive encroachment: Paperless Parts (Smart RFQ Form), CADDi, Lumari, Machine Research are all near this. They could fold triage into existing products. Mitigant: own the small-shop beachhead they explicitly don’t serve and the no-CAD inputs they de-prioritize.
  2. Pain isn’t universal: Some 1–10-person owners genuinely don’t feel RFQ overload. The market is the drowning subset — segment hard or the TAM shrinks.
  3. Extraction trust: One bad miss on a tolerance and an owner stops trusting it. Confidence-flagging and “human-checks-the-flagged-fields” UX is essential, not optional.

14. Structured verdict

Score:                  76/100
Verdict:                GO
Confidence:             Medium
Best-fit builder:       Technical founder strong on VLM/document-AI, paired with a machine-shop domain advisor
Time to revenue:        8–12 weeks (forward-an-email trial → paid)
Capital to launch:      $8–15K ($ inference + hosting + founder time)
Top 3 assumptions to validate first:
  1. Owners pay for triage (not pricing) — 30 interviews + fake-door pricing page
  2. VLM extraction usable on the messy 40% — 100 real RFQs, measure accuracy + correction time
  3. Triage ranking beats gut — backtest against a shop's 6-month quoted-vs-won history
Kill criteria:
  - Abandon if <1/3 of 30 interviewed owners say the inbox (not the calculator) is their real bottleneck
  - Abandon if extraction needs >60s of human correction per RFQ on real-world inputs
  - Abandon if a well-funded incumbent ships small-shop RFQ triage before your v1

15. Next step — 1-week validation sprint

  • Day 1–2: Pull 100 real (anonymized) RFQs — beg them off 5–10 owners in the PM “Overwhelming RFQ Backlog” thread in exchange for a free triage of their pile. Run them through a stock VLM. Measure field-level extraction accuracy and per-RFQ human-correction time.
  • Day 3–4: 30 owner interviews from the named forums/subreddits. One question that matters: “Is your problem deciding which to quote, or pricing the ones you’ve picked?” Put up a fake-door pricing page ($199/$399) and drive the interviewees to it; count clicks-to-”start trial.”
  • Day 5: Go / no-go. Go if (a) extraction needs <30s correction/RFQ on the messy set, and (b) ≥10 of 30 owners say the inbox/triage — not pricing — is the real bottleneck and ≥5 hit the trial button. Otherwise, no-go or re-segment.

The result is falsifiable: a measured correction-time number and a counted interview/fake-door conversion, not a vibe.
