What we build
Systems that ship, and stay shipped.
From first conversation to production, we design and build complete AI products. The same hands that built four acquired platforms build yours.
$63M+ in product exits. Four exits, 10M+ users served, and two Series A companies.
Production AI
has a pulse.
Custom LLM cores, RAG architectures, and agentic workflows — designed, built, and kept alive in production.

Common questions
Once there is something worth talking through, yes. The first exchange happens in writing because it is faster for both of us and it leaves a record. If the work looks like a fit, we arrange a conversation in that first reply.
Typically within 1–2 weeks of signing. We keep our roster intentionally small so we can move fast when the right project comes along.
Most projects run 8–16 weeks from kickoff to production. We work in weekly sprints with live demos, so you see progress continuously. For ongoing partnerships, we offer retainer arrangements.
We price by project scope, not by the hour. Once we have read your brief, we provide a fixed-fee proposal so you know exactly what you're investing. AI system projects typically range from $40K to $150K+ depending on complexity. We offer a $15K discovery sprint to define the right scope before committing to a full build.
Absolutely. We've helped pre-seed to Series A companies build their core AI products. For early-stage teams, we focus on MVPs that validate quickly and scale when you're ready.
Start a project anywhere on this site and the planner opens: five short steps, two minutes, no account. Or write to hello@fortissimo.io. Either way a person reads it and replies within one business day.
