The marketplace
One curated store for real alpha.
Quant developers publish strategies and earn 70% of the performance fee. Investors subscribe to vetted algorithms with transparent, reproducible track records. Two sides, one marketplace — institutional models behind a consumer-grade app.
Discovery
Browse vetted strategies.
Every listing surfaces honest performance — Sharpe, returns, max drawdown, subscribers, and AUM — alongside a verified, reproducible track record. Rank by risk, return, or reputation. No cherry-picked backtests.
Transparency
The whole track record. Verified.
Open any strategy to a full performance dashboard — equity curve, underwater drawdown, risk metrics, and live exposure. Every number traces back to a reproducible pipeline run, so the edge is auditable, not anecdotal.
Why it's trustworthy
Track records you can actually verify.
Anyone can post a pretty backtest. The hard part is proving it's real. Promethean ties every published number to the run that produced it — same data, same code, same seed — so the edge is reproducible rather than just claimed.
Reproducible by construction
Each strategy's performance is computed from a locked pipeline run — pipeline version, dataset versions, hyperparameters, runtime, and seed. Re-run it and get the same result, to the byte.
Point-in-time honest
Track records are evaluated on point-in-time-correct data with realistic fills and slippage — no look-ahead, no survivorship, no curve-fit hindsight.
Audited & rated
A verified badge means the lineage checks out. Discovery ranks on risk-adjusted return and live consistency — reputation that's earned, not bought.
The supply side
Publish once. Earn as long as it performs.
Promote a model from the registry, set your fee terms, and ship it to the marketplace. Promethean handles discovery, billing, execution, and compliance. You keep 70% of the performance fee and watch the earnings roll in.
The economics
Aligned incentives, both ways.
The marketplace only works if developers are paid for real edge and investors only pay when they make money. Performance fees sit behind a high-water mark, and the developer share is the largest in the industry.
For developers
Keep 70% of the performance fee.
Earn on two streams — a cut of each subscription plus 70% of the performance fee. Promethean runs discovery, billing, execution, and compliance. You focus on alpha; reproducible lineage proves it's yours.

Pay for performance, not promises.
Subscribe for a flat monthly fee plus a performance fee charged only above a high-water mark — you don't pay twice for the same gains. Allocate, monitor, and cancel anytime, with full transparency the whole way.
