A studio for measured intelligence.

Heaven Interactive is a Sofia-based applied-AI studio. We build, evaluate, and operate production systems for European enterprise — banks, insurers, logistics, telco. We are small on purpose: a senior team, deep on a few things, slow to grow, fast to ship.

§01

Manifesto

Too many AI projects stop at the demo — notebooks that never leave the vendor's sandbox, dashboards no operator opens twice. That's not the work we take on. We build for the unglamorous middle: the eval harness that catches a regression on Friday, the on-call runbook a junior can follow at 3am, the latency budget a product manager can plan against. The intelligence is in the engineering.

Measurement

Every metric on this site is aggregated from production deployments under live traffic. Evaluation uses a versioned golden-set plus a 5% live-traffic shadow. Latency is measured at p95 over rolling 7-day windows from EU-Central. We will share the methodology document under NDA on request.

Methodology document available under NDA · methodology@heaveninteractive.net

§03

Team

Three principals — two full-stack engineers and database architects who founded the studio, and a co-owner who is our practising general counsel. All based in Sofia. We do not subcontract. The engineer who scopes the work is the engineer who ships it.
