Most projects ship pages, not results.

    After: A product with a funnel and numbers

  2. Before: Three headlines, five buttons, every feature

    After: One problem worth money, and the shortest path to solving it

  3. Before: Launch, then guess

    After: Analytics from day one, a monthly report in plain language

Three fields we know from the inside.

Dmytro Kruhlov

Founder

  • Co-founded MISU, HOWCOW and Vatra. Founded UDonate.
  • At Vatra, a rehabilitation platform with a team of about 15, he leads strategy and business development.
  • Runs Onesse the way he builds products: find the essence, remove the rest, measure.

What you get and keep.

  • The code and the data. They are yours, whoever hosts the product.
  • Nothing to manage. Hosting, infrastructure and support are on us, for a monthly or yearly fee. Or we deploy on your side.
  • A report you read in five minutes. Every month, in plain language.
  • The same team. We take on 1–⁠2 partners a year and support what we build for as long as it runs.
Example: one page of the monthly report

Questions before the first call.

How much does it cost?

We don’t publish prices. Discovery has a fixed price agreed before we start, Build is fixed and paid in milestones, Partner is a monthly retainer. You get the numbers in a proposal after the first call.

How soon will we have something working?

A working MVP comes 3–⁠4 months after Discovery. Discovery itself takes 2–⁠4 weeks and ends with a clickable prototype.

Can we stop after Discovery?

Yes. The plan, the prototype and the estimate are yours, and you can take them to any team.

Who owns the code and the data?

You do. We can host and support the product for a monthly or yearly fee, or deploy it on your infrastructure.

Which industries do you work with?

Health and rehabilitation; agro, construction, equipment rental, logistics and manufacturing; NGOs and foundations.

Who is not a good fit?

We are not the right team if you need “just a website in a week” or choose on price alone. We also need access to your data and people during Discovery.

We take on 1–⁠2 partners a year.
