Cambridge mathematician. YC-backed founder. Currently building at the agentic commerce layer — where AI agents shop, transact, and operate autonomously.
Background: maths → strategy consulting (Oliver Wyman, Bain) → startups → COO. I've raised $42M in venture capital, scaled a company to $50M revenue, and shipped software used by 500k+ people. Now building the infrastructure layer for agent-native commerce.
A shopping CLI built for AI agents, not humans.
Humans configure it once — budgets, approval thresholds, spending policy. Agents use it to shop autonomously. The core primitive is a mandate: a signed, revocable spending delegation that encodes purchase policy. Agents reference a mandate ID on every order; they never see payment credentials.
pip install shop-cli— on PyPI, Python 3.9+- Every command returns JSON. All mutations take
--idempotency-key. Semantic exit codes — agents branch on3(mandate violation),5(low confidence),6(retry-safe network error). - Stack: Python 3.12, typer, pydantic v2, httpx (async), Ed25519 mandate signing, SQLite

Multi-agent pipeline: Claude Code + MCP → recipe generation → cart population → phone notification. No human in the loop after the weekly trigger.
Android symptom checker — 500k+ downloads, medical content partnership with Harvard Medical School. Built in Java; still the highest-distribution thing I've shipped.
