01 — Outcomes
People first. AI where it pays.
Win more work
Find the right tenders and write stronger bids. Open warm doors through your own team’s network. Sell more with the people you already have — growth first, savings as a bonus.
Take out the friction
Replace the spreadsheet-and-email processes that slow your people down with software that fits how you work. Less manual work, fewer errors, faster from lead to invoice.
An AI plan you can defend
Your board or investors ask what you are doing with AI. Answer with concrete business cases owned by your own managers — and working proof within weeks, not another slide deck.
02 — How we work
Start small. Prove it. Then scale what works.
- 01
Scan
Four hours with your leadership: how you sell, deliver and invoice, and where friction and missed revenue sit.
- 02
Business case
Within days, one to three opportunities with the numbers behind them — and a clear owner on your side.
- 03
Live in weeks
Our own AI development pipeline builds it around your process. Your team uses it on real work, early.
- 04
Subscription
A monthly fee instead of a large upfront investment. And if you ever leave, your code and data go with you.

04 — Proof
We run Klapeen on it.
Two founders, one company running on software we built ourselves — and AI agents that work alongside us. If it does not hold up in our own business, we do not sell it to yours.
05 — Partners
You know the market. We build the product.
Domain knowledge and a customer base are the hard part of a software business. If you have them, we bring the build — and can share the revenue.
Domain experts & consultancies
Turn the method you sell by the hour into a product your clients subscribe to.
Software vendors on legacy platforms
Move a desktop package your customers depend on to the cloud — same screens, no big development team.
Platforms & industry networks
Offer your members a smart tool under your own name, built on what you know about their trade.

Beyond guardrails and productivity
Some leaders focus on trust and governance, others on making professionals faster. Both are necessary, neither is sufficient: the frontier is redesigning the operating model itself.
