Kokorosoft

Technology with judgement. Built with heart.

For companies that pay for technology they cannot evaluate.

Kokorosoft is a software development consultancy. We modernise platforms that have fallen behind, lead technology for companies without a CTO and build web and mobile products at a fixed price, with small teams that deliver like large ones.

Why companies call us

Costs keep rising

The infrastructure and vendor bill grows every quarter and nobody can explain why, or what would happen if something were touched.

Nobody can evaluate the vendor

An outside company delivers things, and there is no way to tell whether what it delivers is good or merely expensive.

Every fix breaks something else

Estimates slip, the product is stuck and hiring more people has not fixed it.

Kokoro means heart and mind at once

It is how we work: with the head to decide well what gets built, and with the care of someone who will have to maintain tomorrow what they build today. Professional development, with heart.

  • First, don't break what works

    Tests, observability and controlled deployments before the first new feature.

  • Judgement before code

    What gets built, bought or switched off is decided with numbers.

  • Small teams that deliver like large ones

    Processes and artificial intelligence where it can be tested; people where it cannot.

  • Everything in writing

    Scope, price and what is not included, before starting.
