Quartermast

The certified module marketplace where defense program offices buy interoperable drone components.

Quartermast runs a US government-facing marketplace of pre-verified drone and counter-UAS modules - autonomy stacks, seekers, radios, effectors - each listed with test evidence generated in Quartermast's own ML-driven digital-twin harness.

Test it before you build it

$2,000 · 6 weeks · 32 prospects

Proves a prime will put third-party conformance verification of counter-UAS payloads in writing and vendors will pay deposits for it, for $2,000 in 6 weeks.

Riskiest assumption · A prime's counter-UAS integration lead will accept conformance evidence against a privately published interface standard as a basis for sourcing decisions and commit to it in a signed LOI, rather than waiting for a government-owned interface and reference test suite.

1Focus group: who and where

Two people on each side of one transaction: the mission-systems or supplier-quality lead at a prime or mid-tier integrator (L3Harris, RTX, Leidos, Kratos, AeroVironment scale) currently qualifying counter-UAS sensor payloads for a DoD program of record, and the founder or BD lead at a counter-UAS payload startup that cannot get on a prime's shortlist without a bespoke qualification cycle

where to find 32 · Prime side: the AUSA Annual Meeting (Washington DC, October 12-14, 2026) where every counter-UAS integrator exhibits, NDIA chapter events and its Emerging Technologies division, and companies answering counter-UAS RFIs posted on SAM.gov. Vendor side: the DIU Blue UAS Framework and Cleared lists as a directory of exactly these module makers, plus recent YC and defense-accelerator batches named on this card's cluster

2Sell first, build later

First verification cohort, October 2026: your counter-UAS sensor payload tested against the published Quartermast interface spec in our simulation harness, with a test-evidence dossier delivered to two named prime integration teams within 90 days.

the ask · $4,500 per verification for vendors, $1,000 deposit up front; primes sign a no-fee sourcing-pilot LOI naming a program and a start date

a real yes · A real yes is a $1,000 vendor deposit received by ACH or a prime LOI with a named program and dated start. Spec feedback, 'send this to our supply chain team,' intros, and unpaid interest are not a yes.

3Small experiments

The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.

1. Prime conformance-evidence interviews
$300 · 12 days
Write a 2-page draft interface spec for counter-UAS sensor payloads and a sample test-evidence dossier as PDFs, no code. Book 12 calls with mission-systems and supplier-quality leads at primes and mid-tier integrators, reached through NDIA chapter events and warm intros from defense-accelerator founders, and ask one question: would payloads arriving verified against this spec change a make-buy or sourcing decision, and will you put that in an LOI naming a program. Founder runs every call.
keep going if · 8 of 12 calls happen; 5 leads mark up the draft spec; 3 agree to review an LOI naming a program and a sourcing start date
2. Vendor verification cohort pre-sale
$300 · 21 days
Put up a one-page offer: verification of your payload against the published interface spec, test-evidence dossier delivered to two named prime integration teams, October cohort, $4,500 per verification with a $1,000 refundable deposit invoiced by ACH. Pitch 20 payload vendors pulled from the Blue UAS Framework list and recent accelerator batches by email and phone.
keep going if · 5 of 20 vendors pay the $1,000 deposit; fewer than 3 means the vendor side will not fund verification
3. AUSA prime LOI push
$1,400 · 42 days
Take the marked-up spec and the count of paid vendor deposits to the AUSA Annual Meeting in DC and hold 8-10 pre-booked floor meetings with the prime leads from experiment 1 plus new ones, asking each to sign the LOI with a named program and a Q1 2027 sourcing pilot start. One founder, three days, badge and travel.
keep going if · 2 signed LOIs each naming a program and a dated sourcing pilot

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 · An invoiced, ACH-paid refundable deposit from vendors against the $4,500 verification fee - an invoice rather than a consumer checkout because these are B2B defense suppliers who pay by ACH and need paper for their books; primes sign the LOI, no money, because a prime cannot credibly pay before a supplier agreement clears procurement set up: Stripe Invoicing ↗

what it reserves · One of ten slots in the October verification cohort and dossier delivery to two named prime integration teams

refund · Fully refundable until testing begins, and refunded automatically if the verified listing does not reach a prime team within 90 days.

target · 5 vendor deposits from 20 pitches plus 2 signed prime LOIs within 42 days

before taking money · Counter-UAS payload specifications and test data can be ITAR-controlled technical data, so collect no vendor technical packages and run no tests before an export-control counsel review, and take no money tied to a government contract outside a proper contracting vehicle.

Go: build it if

2 prime LOIs with named programs and dated starts, plus 5 paid vendor deposits ($5,000 collected) inside 6 weeks: build the conformance harness for the first cohort.

Kill: stop if

0 prime LOIs after 12 prime conversations and AUSA, or fewer than 3 vendor deposits from 20 pitches: primes will wait for a government-owned test suite and the marketplace has no paying side.

outreach message

You are integrating counter-UAS sensor payloads, and every new vendor means a bespoke qualification cycle. I am building Quartermast: a published payload interface plus independent conformance testing in a digital-twin harness, so a payload arrives on your desk with test evidence instead of a promise. Twenty payload vendors are lined up for the first verification cohort in October. Can I get 20 minutes this week to walk you through the draft interface spec and hear whether verified-to-spec evidence would change a sourcing decision?

deposit terms

Your $1,000 deposit reserves one of ten slots in the October 2026 verification cohort and applies toward the $4,500 verification fee. It is fully refundable until testing begins, and refunded automatically if your verified listing is not delivered to two named prime integration teams within 90 days. The balance is invoiced when testing starts.

The idea in full

What: Quartermast runs a US government-facing marketplace of pre-verified drone and counter-UAS modules - autonomy stacks, seekers, radios, effectors - each listed with test evidence generated in Quartermast's own ML-driven digital-twin harness. Program offices and primes browse modules already proven to interoperate against a published interface standard, cutting integration from a bespoke contract to a purchase order. Vendors pay listing and verification fees; the deep tech is the simulation and conformance engine, not warehouses.
Why now: The 2024 and 2025 cohorts added 42 and 41 new companies each, most building single modules like Mass Magnetics (US-made magnetics), GUILD (aerospace parts) and Surtr Defense Systems (hardware-agnostic drone defense OS) - fragmentation this fast has no neutral procurement layer, and YC's Fall 2026 RFS names The Future of American Defense outright.
Wedge: first customer and entry point: Start with one category, counter-UAS sensor payloads, verified for one buyer channel: a prime integrating them into an existing DoD program of record, reached through that prime rather than direct government sales.
Path to 100x: Defense procurement of unmanned systems and components is a $10-100B annual market, and whoever owns the interface standard plus the conformance test data becomes the default clearing layer that hundreds of vendors build to - a platform position that compounds as every new module is verified on it. Take rates of 3-5% on transacted volume plus verification fees on a fast-growing vendor base support a $1B+ outcome if even a mid-single-digit share of component spend routes through the marketplace.
Ceiling: Primes and program offices may keep the largest contracts direct, confining the marketplace to small-dollar modules and capping gross merchandise volume.
Closest real companies, as the generator saw them: Surtr Defense Systems builds the operating system for drone defense but sells its own stack; Null Labs sells simulation as a tool to builders rather than running a verified marketplace; GUILD makes parts itself instead of brokering certified modules.
Main risk: DoD standardizes on a government-owned interface and reference test suite, making a private verification marketplace redundant.

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
Owning the interface standard plus conformance data compounds across hundreds of vendors, though DoD publishing its own test suite would erase it.
Bootstrapper
2/5
Software margins are good, yet DoD and prime channel sales with certification fees make the first dollar slow.
Operator
2/5
The marketplace only works if primes and program offices adopt a private interface standard first, and the card admits the largest contracts stay direct.
Technologist
4/5
The digital-twin conformance harness plus accumulated test evidence is genuinely hard to replicate, discounted by DoD publishing its own reference test suite.
Risk
2/5
The stated risk is exact: DoD publishing its own interface and test suite deletes the business overnight, and primes are the only channel.
trends
4/5
Rides the named Fall 2026 American Defense RFS and the 2025 module-builder surge, where fragmentation is only now large enough to need a neutral procurement layer.
