Test it before you build it

$2,000 · 5 weeks · 15 prospects

For $2,000 and five weeks, prove that broker treasurers posting collateral on two or more venues will pay $5,000 up front for a read-only shadow study of the margin a netted requirement would have freed, before any hardware exists.

Riskiest assumption · A broker's treasurer will pay for cross-venue margin netting on the strength of single-house collateral savings alone, before any rival venue accepts the netted risk number.

1Focus group: who and where

The treasurer, head of margin, or COO at a US FCM, broker-dealer, or proprietary trading firm that posts collateral on at least two venue types today - for example a firm carrying Kalshi event-contract positions alongside CME futures or equities - and whose excess collateral is a line item they report on monthly.

where to find 15 · The CFTC's monthly financial data for FCMs page and NFA BASIC, which together list every registered firm with its capital figures (directory); FIA Expo in Chicago this fall, where FCM treasurers and margin heads walk the floor (event); STAC Summit meetings for the low-latency trading infrastructure crowd (community); plus warm intros through investors and former colleagues into brokers already routing event contracts alongside equities, such as Interactive Brokers and Robinhood (channel).

2Sell first, build later

A four-week read-only shadow-margin study sold before the appliance exists: the broker sends daily position and margin files under NDA, and gets back a written report stating exactly how many dollars of collateral a single netted cross-venue requirement would have freed each day of the prior month, starting within two weeks of signing.

the ask · $5,000 per shadow study, prepaid, credited against the first year of a $120,000-per-year appliance license

a real yes · A real yes is a signed SOW with the $5,000 invoice paid, or a signed conditional LOI for the appliance with an install quarter; a treasurer agreeing the problem is real, an offer of free data with no payment, or a request to circle back after budget season counts as nothing.

3Small experiments

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

  1. 1. Quantify the collateral bleed

    $1,200 · 14 days

    Build the target list from the CFTC FCM financial data page and NFA BASIC, filtered to firms active on multiple venue types, and book 15 treasurer calls through warm intros and one Chicago trip timed to a STAC Summit or FIA Expo. On each call, ask them to put a monthly dollar figure on collateral posted above a portfolio-level requirement, walk a two-page mock freed-collateral report, and end by pitching the paid shadow study. Founder-led, no hardware mentioned until they ask.

    keep going if · 8 of 15 treasurers quantify at least $2M of idle cross-venue collateral, and 6 ask for the shadow-study SOW

  2. 2. Sell the paid shadow study

    $700 · 14 days

    Send the SOW to every treasurer who asked: a four-week read-only study, daily position and margin files delivered over SFTP under NDA, output is one report stating the collateral a netted cross-venue requirement would have freed, $5,000 invoiced at signing. Counsel reviews the NDA and SOW templates once; the netting math runs in software on a laptop, since the FPGA matters for latency, not for a retrospective study.

    keep going if · 2 of 15 firms sign the SOW and pay the $5,000 invoice

  3. 3. Appliance LOI on study results

    $100 · 7 days

    Present each completed or in-flight study buyer with a one-page LOI for the 1U appliance at $120,000 per year including support, conditional on the study showing at least $250,000 in freeable collateral. Count signatures, not enthusiasm.

    keep going if · 2 signed conditional LOIs with target install quarters named

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.

$5,000

per prospect, refundable

how · A paid design-partner pilot invoiced up front: the treasurer signs a two-page SOW plus NDA and pays the $5,000 study fee at signing, credited against the first-year appliance license. Chosen because regulated brokers buy analyses through SOWs routinely, while a reservation link for an uninstalled hardware box would not survive their vendor process. set up: Stripe Invoicing ↗

what it reserves · One of three shadow-study slots starting within two weeks, the credited license discount, and first position in the install queue for the appliance's pilot cohort

refund · Refunded in full if the completed study shows less than $250,000 in freeable collateral.

target · 2 paid $5,000 studies from 15 treasurer calls within 35 days

before taking money · The buyers are CFTC- and SEC-regulated brokers, so the study must stay read-only and off the order path, with their compliance team approving the NDA and data transfer before any position file moves.

Go: build it if

8 of 15 treasurers quantify $2M+ of idle collateral, 2 pay the $5,000 study fee, and 2 sign conditional appliance LOIs at $120,000 per year.

Kill: stop if

Zero paid studies after 15 treasurer calls, or fewer than 4 of 15 can put any dollar figure on cross-venue over-posting, meaning the pain is not owned or not measurable.

5 Scripts to run itoutreach message, landing copy, deposit terms · click to open

outreach message

You post full margin at every venue you clear on, and the excess sits idle while event contracts, futures and equities each demand their own collateral. I compute what one netted requirement across your venues would have freed last month - read-only, from daily position files under NDA, nothing touches your order path. The output is a single number: dollars of collateral you over-posted, day by day. Do you have 20 minutes this week to see the sample report?

landing page

How much collateral did you over-post last month? $5,000 prepaid shadow study: four weeks of daily position files in, a freed-collateral report out, credited against a $120,000-per-year appliance license Book a scoping call - three study slots before year end

deposit terms

The $5,000 study fee is invoiced when you sign the SOW and reserves one of three shadow-study slots starting within two weeks. It is credited in full against the first year of an appliance license if you proceed. If the completed study shows less than $250,000 in freeable collateral, we refund the full fee.

The idea in full

What
Marginframe sells a 1U FPGA appliance plus support contract to brokers and venues that carry positions on more than one execution venue. It ingests every venue's order and position feed, computes a portfolio risk number and an optimal collateral allocation in hardware on a deterministic clock, and returns a single netted margin requirement instead of the sum of siloed requirements. The math is an optimal-transport formulation of collateral movement, compiled to gates so the answer arrives before the next order does.
Why now
The radar shows four companies pitching prediction markets in two years (River Markets on prime brokerage, Oddpool on institutional infrastructure, Totalis on derivatives, Arbital on a cross-asset terminal), which means collateral is now fragmented across venue types with no shared risk layer; NSF is separately funding the underlying method with a roughly $200k award on Market Microstructure and Regularized Optimal Transport.
Wedge: first customer and entry point
One broker that is visibly bleeding collateral across two venues, sold founder to founder as a read-only shadow box that reports how much margin it would have freed last week before anyone routes through it.
Path to 100x
Trading risk and connectivity infrastructure is a $1-10B hardware and licence market, and the appliance creates a category that does not exist today: a vendor-neutral cross-venue margin box. Value compounds with each venue and broker on the frame, because every added participant increases the netting set and makes the alternative, posting full collateral at every venue, more expensive, which pushes the market to one frame.
Ceiling
A single large clearing incumbent or a coalition of venues builds the same netting in software and gives it away to keep flow, capping Marginframe at a niche hardware vendor with a few dozen boxes.
Closest real companies, as the generator saw them
The four prediction-market entrants (River Markets, Oddpool, Totalis, Arbital) are software venues, brokerages and terminals competing for traders; Marginframe sells to all of them and competes for none of their users. This is the physical risk plumbing underneath their business, and no hardware player appears on the radar.
Main risk
Venues refuse to accept another venue's netted risk number, so the appliance saves collateral only inside one house and never becomes a network.

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

    FPGA netting box with a real network effect on the collateral set, but a venue coalition giving away software netting caps this $1-10B market fast.

  • Bootstrapper

    2/5

    FPGA appliance development plus colocation for a handful of brokers is real capex before the first support contract signs.

  • Operator

    3/5

    Fragmented collateral is a measurable cost a broker's treasurer owns, but netting only pays once rival venues accept another house's risk number.

  • Technologist

    5/5

    Portfolio margin as an optimal-transport formulation compiled to FPGA gates on a deterministic clock cannot be reproduced by any prediction-market software team.

  • Risk

    2/5

    Netting only counts if rival venues accept another venue's risk number, and prediction-market venues are a regulatorily volatile buyer base.

  • trends

    3/5

    Collateral fragmentation across four new prediction-market venues (term at 6 vs 2) is a genuine 2025-2026 shift, though venues accepting a shared risk number is unproven.
