We build the rails, not the train.
Throughspec started from a simple frustration: AI coding tools are astonishing at generating code and terrible at remembering why. The gap between a good idea and shipped software wasn’t capability - it was process. So we built the process, and made it a precondition.
Process is a feature.
The best tooling doesn’t just generate output - it shapes how the work gets done. We treat the workflow itself as the product, and the generated code as a downstream effect of a good process.
Memory is leverage.
A project that remembers its own decisions is exponentially cheaper to extend. We optimize relentlessly for token-lean, append-only memory so the hundredth prompt costs about what the first did.
Determinism over cleverness.
A predictable, boring structure beats a clever, surprising one. We’d rather refuse to proceed than improvise - every gate, every step, every log exists to remove ambiguity.

AI engineer and researcher shipping end-to-end AI products from specification through production. Prior work includes VAi, an AI assistant that talks to recruiters on Vishal's behalf which went viral and was featured by CNBC.
Throughspec is the SDLC I wish existed when I started building with Claude Code - spec-driven, drift-proof, token-lean. Open to work across the US & Europe.
