Test it before you build it
$1,700 · 3 weeks · 30 prospects
Prove that ITAR-registered machine shops will prepay for qualified defense RFQ flow and sign a take-rate agreement, for $1,700 and 3 weeks of manual brokering.
Riskiest assumption · Owners of ITAR-registered machine shops will prepay monthly for qualified defense RFQ flow and sign a 5% take-rate agreement, even though they could take any buyer relationship direct after the first job.
1Focus group: who and where
The owner or head estimator at a 5-50 person ITAR-registered CNC machine shop within a day's drive of the Los Angeles or Boston defense hardware clusters, running under 80% spindle utilization this month and quoting defense work through brokers who take weeks and share nothing
where to find 30 · NTMA local chapter rosters in Southern California and New England (community), Thomasnet's supplier directory filtered to ITAR-registered CNC milling shops in California and Massachusetts (directory), IMTS 2026 in Chicago Sept 14-19 where thousands of job shop owners attend (event), plus the Practical Machinist forum where estimators discuss defense quoting
2Sell first, build later
Founding membership in Toolpath's defense RFQ network: at least 3 qualified, compliance-checked RFQs matched to your machine list within 30 days, with quotes routed to the buyer same day, starting the week you pay.
the ask · $299 for the first month prepaid, locked at $299/month for 12 months, plus 5% of jobs won through the platform
a real yes · A real yes is $299 charged and the take-rate agreement signed by the owner; compliments, 'send me leads when you have them', and unpaid trial requests do not count.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Prepaid founding member pitch
$300 · 10 days
Build a list of 30 ITAR-registered CNC shops near the LA and Boston clusters from Thomasnet filters and NTMA chapter rosters. The founder calls the owner or head estimator with a real sample RFQ packet in hand and pitches the $299 prepaid founding membership plus the 5% take-rate agreement, closing on the call with a card or ACH payment.
keep going if · 10 of 30 owners prepay $299 and sign the one-page take-rate agreement
2. Live RFQ broker round
$450 · 12 days
Get 3 live RFQs for milled aluminium or titanium parts under 20 pieces from YC-stage defense hardware teams such as GUILD, Mass Magnetics or Tenet Industries. Route each RFQ to 8-10 member shops by phone and email, hand quotes back to the buyer within 48 hours, and track whether a job is awarded through you.
keep going if · Each RFQ draws 3+ quotes inside 48 hours and at least 1 of 3 jobs is awarded through Toolpath
3. IMTS floor sweep
$950 · 5 days
Walk IMTS 2026 in Chicago (Sept 14-19), targeting small job shop owners exhibiting or attending. Pitch the same founding membership face to face and take payment on a card reader on the spot, logging every pitch and objection.
keep going if · 5 prepaid memberships collected across 40 floor pitches at the show
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.
$299
per prospect, refundable
how · First month prepaid by card or ACH before the first RFQ is delivered, alongside a one-page founding agreement with the 5% take rate signed by the shop owner - the same way shops already prepay directory listings, so the instrument matches how this buyer spends
what it reserves · One of 20 founding shop slots, the $299/month price locked for 12 months, and first look at RFQs within driving distance of the shop
refund · Full refund within 5 business days if fewer than 3 qualified RFQs matched to the shop's equipment arrive in the first 30 days.
target · 10 prepaid memberships from 30 pitched shops within 21 days
before taking money · Never transmit ITAR-controlled technical data to a shop before confirming its DDTC registration and US-person handling in writing, and route controlled drawings through the buyer's own transfer process until counsel approves yours.
Go: build it if
10 prepaid $299 memberships, all 3 live RFQs triple-quoted inside 48 hours, and at least 1 job awarded through the platform within 3 weeks
Kill: stop if
Fewer than 3 prepayments after 30 owner pitches, or no RFQ draws 3 quotes inside 48 hours - shops will not pay and the speed claim fails

outreach message
You run an ITAR-registered CNC shop and your defense RFQs still arrive through brokers who take weeks and tell you nothing about the buyer. I match shops like yours to funded defense hardware startups that need aluminium and titanium parts, under 20 pieces, quoted inside 48 hours. I have a live RFQ in hand right now that fits your machine list. Founding membership is $299 for the first month, at least 3 qualified RFQs in 30 days or a full refund. Do you have 20 minutes this week?
landing page
Defense RFQs matched to your machines, quoted in 48 hours. $299 first month prepaid buys at least 3 qualified, compliance-checked RFQs in 30 days, price locked for 12 months. Claim one of 20 founding shop slots.
deposit terms
Your $299 covers your first month as one of 20 founding shops and locks the $299/month rate for 12 months. If we do not deliver at least 3 qualified RFQs matched to your equipment in your first 30 days, we refund the full amount within 5 business days. A 5% fee applies only on jobs you win through Toolpath.

The idea in full
- What
- Toolpath is a marketplace where small US machine shops, casting houses and PCB assemblers list live capacity and compliance status, and defence hardware buyers post drawings that get quoted in hours instead of weeks. The paying side is the shops: they subscribe for qualified lead flow and pay a take rate on won jobs, which starts producing revenue in month one. Toolpath runs field ops for first-article inspection and expediting, and integrates with shop quoting and ERP systems rather than building manufacturing technology.
- Why now
- YC's Fall 2026 Requests for Startups names The Future of American Defense, and this cluster added 29 companies in 2024 and 25 already in 2026, nearly all of them hardware: GUILD, Mass Magnetics, Tenet Industries, Isengard Industries Inc, Wardstone and Hop Aero all need machined parts and magnetics at low volume and short notice. Gallos raising $50M on 2026-08-17 as a defence tech investor and builder means the buyer side keeps growing.
- Wedge: first customer and entry point
- The twenty or so YC-stage defence hardware companies building first articles now, matched against machine shops within a day's drive of them, starting with aluminium and titanium milled parts under twenty pieces.
- Path to 100x
- US defence and aerospace hardware procurement flowing through small suppliers is a $100B+ annual base, and quoting marketplaces are winner-takes-most because the fastest quote wins the job, and quote speed is a function of how many shops are already on the platform. Once primes and their supplier-diversity programmes route RFQs through Toolpath as a channel, joining stops being optional for a shop.
- Ceiling
- Defence parts buying is relationship-bound and audit-heavy, so the platform may plateau as a lead-gen tool for prototypes and never touch production programmes.
- Closest real companies, as the generator saw them
- GUILD makes aerospace parts faster and cheaper for defence by owning production; Mass Magnetics builds USA-made magnetics itself. Toolpath owns no machines and instead makes the existing fragmented shop base quotable and compliance-checked, so its supply grows without capital.
- Main risk
- Shops quote through the platform once and then take the relationship direct, collapsing the take rate.
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
3/5
Fast quotes create real network effects, but shops taking the relationship direct plus field ops for first-article inspection erodes the take rate.
Bootstrapper
4/5
Shops pay for qualified lead flow in month one, the same way they already pay for directory listings, with no machines to buy.
Operator
4/5
Machine shops pay for qualified lead flow from month one and defence buyers wait weeks for quotes, though shops can take the relationship direct.
Technologist
1/5
Owns no machines and no manufacturing technology, so it is quoting workflow plus field ops that shops route around after the first job.
Risk
2/5
Take rate leaks the moment a shop and a buyer meet, and the wedge is twenty YC-stage prototype customers.
trends
4/5
Directly rides the Fall 2026 Future of American Defense RFS and a defense cluster with zero shutdowns, with month-one revenue while the window is open.
