Areas
Each area can be booked with any of the formats. Hours are indicative: the diagnosis gives you the estimate for your case.
We define the roles you need (and the ones you don't), prepare the job posts and the technical test, onboard new people and leave a working methodology the team understands and follows.
We turn the product vision into milestones with scope per version, and organize the board so everyone knows what gets done, in what order and why.
We design the architecture and build with your team or on our own, always with the code 100% yours.
We give the product design direction, build or review the design system and audit the interface so the experience is consistent on every screen.
We automate integration and publishing, define a release process the team can repeat, and take care of stability and urgent fixes.
We define the event plan and the KPIs that matter for your product, and set up a weekly report for leadership with what happened and what needs deciding.
Every month we review capabilities and costs across cloud, SaaS tools and AI, and bring concrete decisions to leadership: what to keep, what to cut and what to optimize.
We bring GDPR into the product: data deletion, versioned consent and a review of rules and access, so what your privacy policy says is actually enforced in the code.
Not legal advice: we handle the technical side alongside your legal advisor.
Technical leadership is handled by the founder. For specific work (design, development) we can bring in specialists from our network, always coordinated by us and at the same rate.
AI specialty
If your product uses AI, or you want it to, we help you take it to production with human control: evaluations, limits and cost per result.
AI models consume tokens. That's billed separately, at the provider's cost with no markup, and we estimate it before we start. We pick the model per task:
| Task type | Typical model | $ / million (in · out) |
|---|---|---|
| Classification and routing | Claude Haiku · GPT mini | $1 · $5 |
| General work | Claude Sonnet | $3 · $15 |
| Hard reasoning | Claude Opus | $5 · $25 |
Build (MVP)
~5–30 M tokens
roughly €30–250 in inference, depending on complexity
In operation
≈ €30–150/month
AI features in production, depending on volume
Reference figures, not a bill. You own the API keys; if you prefer, usage goes straight to your own provider account.
