Why Upheave
No middle management, no offshoring. You work directly with senior people in your timezone, with your data and IP kept in the EU.
We optimise for your results, powered by the latest technology, not the other way around.
AI embedded into the operations that run your business, delivering outcomes in production, not pilots and demos.
We lead you through a delivery process refined over 15 years. You don't have to figure it out alone.
Built in from day one, so you can ship with confidence across the EU.
Selected work
Proprietary tooling
For three years, we've built in-house AI expertise, processes, and tooling around real client work.
Now we use that stack to ship AI-enabled products faster, with less guesswork.
Autonomous Operations
Software that keeps working while everyone's asleep: autonomous LLM agents that run your operations around the clock.
Conversational Intelligence
Your processes and services, reachable through natural conversation across web, WhatsApp, email, and voice, for customers or your internal team.
Rapid Custom Development
Bespoke software for well-scoped problems, engineered and shipped fast when off-the-shelf won't cut it.
Internal Operations Agent
Our own AI operator, plugged into Slack, GitHub, Claude, and Nucleus to orchestrate work and drive outcomes autonomously.
LLM Observability & Governance
Every AI system we ship runs under full observability and governance: its costs, behaviour, and outputs continuously audited, so the AI in your business stays accountable, compliant, and never a black box.
The team
No project gets reshuffled mid-build. The engineer who scoped your auth flow ships it. The designer who mapped your onboarding sees it through to production. When you join a call six months in, you recognize every face - and they recognize your codebase.
Decisions happen in the room, not after.
Two of us co-founded Upheave and still work on client projects, but we're seniors in the same team - not a layer above it.
