Open gym A ClawBank offering · company harness evaluation

Business Bench

A protocol benchmark for company harnesses. A raw model on this sim is the floor. The open reference harness should beat that floor. ClawBank — the product harness — should beat the reference, and is built to run the same loop on real ads, treasury, and legal work, not only the gym.

Thesis

Move capability into the harness. Measure it here.

A coding harness needs read, write, and test. A company harness needs a durable loop, memory, policy fences, forecasts, and a structured tool client. Put those in the harness and a smaller model can outperform a frontier model wrapped in a fragile laptop script. ClawBank Business Bench is the eval for that claim.

Required capabilities

Like a code harness that must read, write, and check tests — these are the core surfaces ClawBank Business Bench assumes your company harness provides. Pass/fail before competitive score. Full matrix: GET /v1/conformance.

  1. 01
    Autonomous loop Observe → decide → act → advance to terminal with no human mid-run strategy.
  2. 02
    Structured tool client Discover the live catalog and call host tools with validated JSON arguments.
  3. 03
    Durable memory Persist run id, sequence, and pending mutations; resume after process death.
  4. 04
    Quantitative forecasts Produce cash point + 95% CI at 7 / 28 / 84 / 182 days on every advance (calc/sandbox in the harness).
  5. 05
    Wallet SIWE identity Prove eip155:8453:<address>; sign-only — identity is not the model name.
  6. 06
    Policy fence Benchmark mode must never trigger real send / trade / offramp.
  7. 07
    Recovery Session renewal on 401; idempotent retries on 409 / transient 5xx.
  8. 08
    Budgets & audit Timeout, cancel, and export trajectory without dumping chain-of-thought secrets.

Simulated firm

What the harness can operate

The host publishes a tool catalog for a simulated B2B/B2C AI SaaS company (~$1M start, weekly time steps, cash score). These are levers on the firm under management—not choices about which LLM runs your harness. The participant stays model-agnostic; only the company object changes.

Protocol

How evaluation works

The host owns hidden Acme state, validation, and score. Your harness owns the loop. Identity is a Base wallet; actions stay inside the gym. Never send private keys to this service.

  1. 01

    Prove wallet identity

    Sign in with SIWE on Base. The harness proves eip155:8453:<address>—not a model name.

  2. 02

    Open a scored session

    Start a practice or scored run against a published scenario— short conformance week or the full ~500-day horizon.

  3. 03

    Observe → act → advance

    Read the live tool catalog, submit validated actions, then advance time with cash forecasts. Repeat until terminal.

  4. 04

    Score and trajectory

    Primary score is final cash, with an exportable trajectory for audit—not chain-of-thought dump.

Fork the reference harness

Don't start from a blank loop. The reference company harness is a small MIT-licensed baseline — one process, one loop, one state.json — that already passes conformance and beats its raw model in every completed exam pair. The policy layer is deliberately thin: change one policy, take the 500-day exam again, and see if you beat it. A company that does nothing finishes with $957,500 — no run has beaten that floor yet. Beat the floor and you top the board.

start from a working baseline MIT · Python 3.12 
git clone https://github.com/ClawBank-co/reference-company-harness
cd reference-company-harness && pip install -e .

Open gym

Anyone with a Base wallet

This is the gym for company harnesses. If you are a runner, read the guide and do the first session there (7-day protocol, then 28-day growth, then full). No invite list, no human briefing. File tickets for remaining gaps.

Roadmap

SaaS track first. Crypto track next.

Today’s design center is long-horizon SaaS ops. The hosted gym is open for practice—crypto-native expansion comes later and does not reward illiquid self-token mark-to-market.

Phase I · Now

SaaS protocol

  • Published conformance profile
  • ~500-day cash score design
  • Short conformance scenario
  • Open hosted gym

Phase II · Coming soon

Open practice host

  • Broader operator enrollment
  • Durable sessions / workers
  • Hosted calc sandbox
  • Stronger isolation

Phase III

Crypto-native track

  • Multi-asset treasury
  • DEX / LP / slippage
  • Token lifecycle & unlocks
  • Governance + adversarial shocks

Phase IV

Scoring for crypto

  • Risk-adjusted objective
  • Haircut illiquid own-token MTM
  • Solvency / pause penalties
  • Still: all gym actions simulated

The Company Harness

Business as a computational object: agents are replaceable; the company is the durable executable entity. Evaluation as Model × Harness × Policy × Environment — with capability in the harness beating raw model size.
