Pigfox LLC is a Go engineering shop building AI and blockchain systems for teams that need them running in production, not demoed in a deck.

Founded in 2005, with 15+ years on backend infrastructure — messaging pipelines moving ~30M messages a day, gRPC services on Postgres and Cassandra, serverless AWS, and 7+ years of production Go.

What we build

AI pipelines — LLM-backed analysis, content generation, and automation wired into real products, with the observability to know when they drift.

Blockchain systems — Solidity under Foundry, Slither, Echidna, and Medusa. Groth16 circuits, UUPS proxies, ERC-721/20/3643.

High-throughput Go — worker pools, bounded queues, profiled under load and published with the numbers.

Full products — Market Verdict (marketverdict.app) is our own SaaS: Go monolith, Postgres, Stripe, 10-language i18n.

Every blockchain demo on pigfox.com runs live on Base Sepolia against contracts we deployed. No mocked state. Click one and watch the transaction land.
