Software for real workflows · Built on Kumiko · Your code, your data

You know your business.
We turn it into software.

We build applications for workflows currently spread across spreadsheets, email and disconnected tools. Complaints, maintenance, customer portals or operations: you bring the process, we build the right solution.

Built on Kumiko: publicly inspectable, self-hostable, and not tied to a closed platform.

Why Kumiko

Built for you, without starting from zero.

Kumiko already covers the difficult foundations of business software. That lets us spend your time and budget on your process instead of rebuilding sign-in, permissions, documents, search and change history for every project.

Live today

Proven building blocks, shaped around your work.

Users, roles, permissions, search, documents, notifications and traceable changes do not need to be reinvented for each project. We tailor them to how your team works.

Pilot format

A clear path to a useful first version.

We look at your workflow, build a first solution, then improve it with your team. You see early what works and what is actually needed.

Hosting posture

Your data stays under your control.

Your application can run in Europe, inside your own network or on-premises. You also choose the AI models and providers that meet your requirements.

See pricing + operating model →

Lock-in posture

No black box or unnecessary lock-in.

Your application and data stay in your environment. Kumiko is a publicly inspectable, self-hostable foundation, not a closed low-code platform.

Compare with Retool →

Lean operations

Modern software without unnecessary weight.

Kumiko uses TypeScript, Bun and Postgres instead of a heavy enterprise stack. Your application gets the building blocks it needs, not an oversized infrastructure.

Is this the right fit?

Kumiko works best when an important workflow needs to improve without forcing your business into a standard product or a new dependency.

Good fit

  • Teams whose important workflows are spread across spreadsheets, email and disconnected tools.
  • Businesses that want software to fit their process, rather than adapting their process to standard software.
  • Projects that should become tangible through a useful first version in weeks.

Probably not a fit

  • Consumer apps or products optimized mainly for growth loops, app-store UX, or high-volume public traffic.
  • Extreme realtime, edge, or hyperscale infrastructure problems as the central requirement.
  • Teams looking only for a generic no-code tool, not a long-term solution they can own.

How we work

From a workflow to software people actually use.

A good project does not start with a feature list. We start with the work that should run better.

01 / 03

You show us where work gets stuck.

We learn your workflow, the people in it, and where time, information or visibility are being lost today.

02 / 03

We build a first version your team can use.

No months of concept work: you get something useful early and can see whether it actually improves day-to-day work.

03 / 03

We improve what matters, together.

Feedback from daily work determines the next step. The application grows with your process instead of getting in its way.

The technical foundation is already there. We invest together in your workflow, not standard functions every project would otherwise rebuild.

What we build

Software for the work that happens every day.

The examples differ. The principle stays the same: we bring your workflow together in an application that works for the people using it.
