Trading
Poor Hedge Fund
Proprietary algorithmic trading
The main book. A hedge fund minus the funds — we trade our own capital, on recorded order books, with the benchmark fixed before the run.
poorhedgefund.comLet Man Know What Man Can
We only trade what
we can prove.
Supersolid Systems is a quantitative trading firm. We build the platform our own strategies run on — recorded order books, benchmarks fixed before the run, and a gate that refuses the order instead of explaining it afterwards. We license that infrastructure to other desks, and we still build products with founders.

The platform
Everything we trade goes through it first.
We did not build a product and then look for a desk to sell it to. The platform exists because our own capital sits on the other side of it. LEAN runs underneath. The layers above model what LEAN does not: contracts that resolve, settlement reconciled on chain, and expiry booked at the real verdict.
Backtests on real books
Replay against recorded depth, second by second. Not a reconstruction.
Benchmarks fixed up front
The comparison is registered before the run, so nobody picks it afterwards.
Compliance at the gate
Jurisdiction checked before an order is signed. Refusals go on the record.
Positions you can read
Mark-to-bid, settlement reconciled, expiry at the verdict rather than worst case.

What we do
Two books, one method.
Measure it before you commit to it. That rule runs the desk, and it runs the way we build with founders.
Primary
Quantitative trading
Our own capital in prediction markets, run through the platform that has to score a strategy before it can trade. We license the same infrastructure to other desks — infrastructure, software, consulting and support — and we take on strategy work for firms that want a second opinion backed by a corpus.
The trading platformAlso
Venture building
We still partner with solo founders and domain experts who have the vision but need the team. Engineering, design, AI workflows, infrastructure, capital and legal — and the founder keeps the company. It is the same discipline pointed at a different problem.

Everything but the idea.
Trading is the main book. This one is older, and we still run it: you bring the vision and conviction, we bring engineering, design, AI, capital, legal, and the determination to make it work.
Product Engineering
Full-stack development across iOS, Android, web, and desktop, with senior architects embedded from day one.
Product Design
UX research, interface design, and product strategy that turns rough ideas into polished experiences.
AI-Powered Workflows
Custom AI workflows using the best models on the market, designed to give you the confidence to shape your own product over time.
Infrastructure
CI/CD, cloud, monitoring, and deployment automation that ships your product continuously from commit one.
Early-Stage Investment
Precision-targeted, well-thought-out investments at the earliest stages, putting our own capital where our conviction is.
Incorporation & Legal
Company formation, equity structuring, contracts, and IP handled properly from the start, so the cap table is clean when it counts.
Investor Network
Where founders and investors meet.
Our invite-only platform connects the companies we build with investors who understand what we do. Browse each project's timeline, register interest, ask questions, and communicate directly with the teams. Without noise or cold outreach, just the right people seeing the right info.
Skin in the game. Determined to succeed, whatever it takes.
We trade our own capital on the platform we sell, and we take equity in the companies we build. Both books run on the same rule: we only win when the thing actually works, so we would rather find out early than be told a good story.

A strategy to validate, a desk to equip, or a company to build.
