Three creators, no middleman.

We knew we do our best work together. That's why we founded Sakeus in 2022.

The three of us design, build and look after your product. You talk to us directly, and all of us are involved from the very start.

When your needs change after launch, we pick up where we left off. We already know your product, so you don't have to explain everything again.

— Simo, Henri & Virgil

  • Over 10 years of shared experience
  • Clients with us since day one
  • No salespeople, only creators
  • Clients from Lappeenranta to Michigan
  • Boringly solvent — 89% equity ratio

What our clients say

“I sleep well at night knowing the application is safe in your hands. And I wake up excited to see all of the cool new things you build.”

Common questions

01 Do I need a fully formed idea?

No. The final solution usually isn't obvious at first, so we often start with what you're trying to solve. In a design sprint the idea gets shaped and tested with a prototype before a line of code is written.

02 Who actually works on our project?

The three of us. We don't use subcontractors or outsource our work, so your product is built by the same people you plan it with. Nothing gets lost in hand-offs, and you always know who's writing your code.

03 Can I hire you for just design or just development?

Yes. We also do UI/UX design on its own, or development from an existing design. We get the best results when we're involved from the start, though: when the same people design and code, the designs are buildable and the build matches the design.

04 What does development cost?

The prices listed for our services are examples. Every project is different. We bill for actual hours worked, in 15-minute increments, and send a timesheet with every invoice. Knowing your budget lets us plan and prioritise what to build: the same problem has a very different solution at €10,000 than at €100,000.

05 Do you build mobile apps?

Mostly we build web apps, which can be wrapped as a mobile app and published in the app stores when needed. Every interface we build is always responsive: it adapts to the screen size, so your product works just as smoothly on a phone, a tablet or a desktop. One product for every device also means less to maintain.

06 What technologies do you use?

We mostly build with Ruby on Rails, which we have long experience with. It's a mature, stable choice for products that are meant to last. For interfaces we use React and other modern tools where the product calls for it.

We use AI agents to speed up development, but we don't compromise on creativity. We never use AI-generated images, and every image on this site is either licensed or edited by us.

07 Can you take over a product someone else built?

Yes, as long as it's also being developed further. We still maintain and develop services that are over ten years old, and how we approach it depends on the technologies chosen and the quality of the code. As a rule, we don't take on apps built by others for maintenance only: our speciality is building new products and features.

08 Who owns the code?

You do. All the design and code we produce is handed over to you, intellectual property rights included. We build on open-source technologies such as Ruby on Rails. No single party owns them; they're used under open licences (e.g. MIT) that allow free commercial use without licence fees. So your product isn't locked to us.
