Test it before you build it
$1,000 · 4 weeks · 20 prospects
Prove hardware startups will convert firm 24-hour CNC quotes into 3 prepaid purchase orders, for $1,000 in 4 weeks.
Riskiest assumption · Hardware startups that already have Xometry and incumbent shops quoting them will send a live RFQ to an unknown broker and prepay a PO for a firm-priced part with a guaranteed ship date.
1Focus group: who and where
Mechanical engineering lead or hardware procurement owner at a US defense-adjacent hardware startup, seed to Series B, 10-100 people, who ordered CNC-milled parts in the last 60 days and is currently waiting on emailed quotes that gate a build milestone
where to find 20 · Warm intros through seed investors and advisors in defense tech (channel), the public YC startup directory filtered to hardware and defense companies for a named target list (directory), IMTS in Chicago this September for buyer and shop meetings in one trip (event), and Practical Machinist forum plus r/machinists for the supply side (community)
2Sell first, build later
A firm quote within 24 hours on your next CNC milling RFQ, price and ship date guaranteed in writing, parts machined by vetted US shops with hand-written design-for-manufacturing notes, first parts delivered within 3 weeks of PO.
the ask · Per job at the quoted firm price with a 10-15 percent Millrun margin built in; $1,000 minimum prepayment per PO
a real yes · A countersigned PO with 50 percent prepaid is a yes; 'send us your rate card', requests for free sample quotes, and 'we would try you on the next build' are not
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Firm-quote RFQ conversion
$200 · 14 days
Offer 20 target startups a firm price and guaranteed ship date within 24 hours on their next real CNC milling RFQ, EAR99 parts only. The founder prices each STEP file and drawing by hand against rate sheets from three partner shops, then sends a written quote with the guarantee. This is Wizard of Oz pricing; the ML comes later, the guarantee is real now.
keep going if · 8 of 20 targets send a live CAD package and 5 accept a quote review call
2. Idle-capacity shop sign-ups
$0 · 7 days
Call 20 CNC shops sourced from Practical Machinist, r/machinists, and NTMA chapter member lists. Ask each for a signed rate sheet, hourly rates by machine, and committed open capacity for the next two weeks, in exchange for first-priority routed jobs at no fee for the pilot.
keep going if · 10 of 20 shops return signed rate sheets with committed next-two-week capacity
3. Prepaid purchase orders
$800 · 14 days
Convert accepted quotes into countersigned POs with 50 percent prepaid, $1,000 minimum, price and ship date guaranteed in writing, parts free if either slips. Route each job to a signed shop; the $800 covers one calibration part to vet the first shop and a buffer for a mispriced first job.
keep going if · 3 prepaid POs at 10 percent or better gross margin after shop cost
4Collect a deposit up front
Tesla took $1,000 refundable reservations for the Model 3 and $100 for the Cybertruck before building either: the deposit is the measurement, not the revenue.
$1,000
per prospect, refundable
how · A 50 percent prepayment invoiced against a standard purchase order that the buyer's procurement signs and Millrun countersigns with the price and ship-date guarantee; chosen because these buyers already run on POs and a prepaid PO is the only yes that costs them something before parts exist set up: Stripe Invoicing ↗
what it reserves · the quoted price, the guaranteed ship date, and a slot in the first 10-job routing cohort with hand-checked DFM feedback on every part
refund · Refunded in full within 5 business days if the ship date is missed or the parts fail the drawing.
target · 3 prepaid POs from 20 firm quotes within 30 days
before taking money · Screen every RFQ for export control and accept only EAR99 parts, never ITAR technical data, until the company has export counsel and DDTC registration.
Go: build it if
8 of 20 targets send a live RFQ, 3 or more prepaid POs land, and hand-quoted jobs clear 10 percent gross margin after shop cost within 30 days
Kill: stop if
fewer than 8 of 20 targets send a real CAD package, or zero POs after 20 firm quotes, or mispricing losses above 20 percent of quoted value on the first jobs

outreach message
Your team is probably waiting a week on emailed quotes for CNC parts that gate your next build. Send me your next RFQ, the STEP file and drawing, and you get a firm price and a guaranteed ship date within 24 hours, machined by vetted US shops with open spindle time, EAR99 work only for now. If the price or the date slips, the parts are free. Worth 20 minutes this week to walk through your current part backlog?
landing page
Firm CNC quotes in 24 hours, ship dates guaranteed Prepay 50 percent, $1,000 minimum, and your price and ship date are locked in writing Send your STEP file for a firm quote today
deposit terms
Your purchase order is confirmed with a 50 percent prepayment, $1,000 minimum, which locks your quoted price and guaranteed ship date. If we ship late or the parts fail your drawing, the prepayment is refunded in full within 5 business days. The balance is invoiced on delivery, net 15.

The idea in full
- What
- Enterprise hardware teams upload CAD files and get firm, guaranteed quotes in seconds from geometry models trained on part-price-outcome data, with jobs routed to idle capacity at US machine shops. Automated design-for-manufacturing feedback plus capacity matching pushes the cost and lead time of custom components toward a 10x collapse. The pricing models need years of part-outcome data before quotes can be guaranteed, so the road is R&D first, liquidity later.
- Why now
- Three companies across the last two YC batches - Waybill (S26), Stoa (S26), and Reframe (W26) - attack hardware procurement, and federal money like the Western Hemisphere critical minerals supply chain grant (closes 2026-09-21) is pushing reshoring; yet the supplier side, idle US machine-shop capacity, still has no ML-priced marketplace.
- Wedge: first customer and entry point
- Founder-sold to defense-adjacent hardware startups - the same buyer profile Waybill serves - needing CNC-milled parts in days, starting with one process (CNC milling) and twenty vetted shops.
- Path to 100x
- US contract manufacturing is a market in the tens of billions where quoting still takes weeks of human back-and-forth; instant firm pricing collapses that cycle and takes a cut of every routed job. The endgame moat is distribution - a buy button embedded in CAD and PLM tools that makes Millrun the default path from design to purchase order, with export-controlled defense work adding a compliance layer competitors must also clear.
- Ceiling
- The long tail of manufacturing processes resists model coverage, capping the share of custom-parts spend that instant pricing can ever address.
- Closest real companies, as the generator saw them
- Reframe runs an AI-native procurement marketplace for hardware but around off-the-shelf components, not ML-priced custom parts; Waybill is managed procurement service for hardware teams; Stoa is a market for AI hardware, not contract manufacturing.
- Main risk
- Guaranteeing ML-generated quotes means eating losses on every mispriced part for years until the model converges.
Five judges
Each judge scores every idea in the catalog with a named rubric; the venture judge decides whether a card is shown at all (4-5 is venture-grade).
Venture investor
4/5
Xometry-shaped: instant ML pricing on tens of billions of US contract manufacturing, with a CAD-embedded buy button as compounding distribution.
Bootstrapper
1/5
Guaranteed ML quotes mean eating losses on mispriced CNC parts for years before the model converges.
Operator
4/5
Hardware teams already burn weeks of email quoting and pay machine shops now, so instant firm pricing hits a felt, budgeted line.
Technologist
4/5
Geometry models trained on part-price-outcome data compound with every routed job, and guaranteeing quotes forces an accuracy bar competitors must fund losses to reach.
Risk
2/5
Guaranteed ML quotes mean eating mispricing losses for years, and defense-adjacent CNC work carries export-control exposure the card never says it is licensed for.
trends
2/5
Instant CAD quoting is Xometry's decade-old model; reshoring grants add at most a point and the cited YC procurement trio does not make quoting newly possible.
