Greenhouse origin

Plant the AI wedge that compounds

Custom AI Seed is the early-stage arm of the Clutch Developer studio, run by Pedro Manfredi in Barcelona.

Twelve years shipping product — now paired with an AI-first experimental practice: scoped seeds, evals, cost caps, and a two-week window so sparks become retained capability instead of demo graveyards.

Belief

Wedge over platform

One sharp capability earns retention before you fund a lab.

Method

Kill criteria early

Stop rules save months of polite failure. Written before day one.

Models

model-agnostic

Speed when the spark needs it; private stacks when the data must stay local.

We build for founders who want a measured seed, not a multi-agent monorepo on day one.
