No pitch deck. Just a conversation about what you're building.
Who we are
A Gothenburg-based engineering partner.
Our people join your team, learn your codebase, and start shipping from day one. We use AI throughout the way we work, from troubleshooting to new development. We've done this for companies like Volvo Group Connected Solutions and Polestar.
What we offer - Three ways we work with you.
Pick what fits, or combine them.
Senior Engineering, On Demand
- Senior developers and architects who integrate into your team, not just fill a seat
- Cloud, infrastructure, and platform expertise built in
- Ownership from day one - no ramp-up period, no hand-holding required
- Proven track record with teams at Porsche, SKF, and Coop
AI That Ships
- Hephaestus Sprint: one RAG system or agent in production in 4–6 weeks, with evals
- Managed AI Ops: monthly care for live AI. New features are fixed-price change orders
- AI Coding Rollout: repo context, agent skills, security boundaries and CI gates
- Every engagement ships a golden eval set. Data stays in your environment
We take care of your platform
- We take over operations, support and further development of your app, portal or connected product
- For companies without their own development team, or with one developer who needs back-up
- Starts with a two-week platform check at a fixed price
- AI throughout the work, so a small team is enough
References - What engineering leaders say
