Customer feedback

Right from the start, we really liked ELEKS' commitment and engagement. They came to us with their best people to try to understand our context, our business idea, and developed the first prototype with us. They were very professional and very customer oriented. I think, without ELEKS it probably would not have been possible to have such a successful product in such a short period of time.

Outcome-oriented cooperation

Flexible risk-sharing cooperation
models tailored to your needs

Our services are built around flexible cooperation models designed to meet the diverse needs of our clients while ensuring speed, quality, and transparency. Whether you're launching a new product or transforming an existing one, our models adapt to your business context and delivery expectations.
We offer three primary cooperation models:
Fixed price

Ideal for well-defined scopes, this model includes milestone-based payments and relatively low scope flexibility. It ensures predictability and budget control for structured projects.

Milestone-based payments
Quality-based SLAs
time and material
Time and material with budget cap

Designed for applications and products with evolving scope, this model sets a budget ceiling while allowing flexibility. A conditional final payment ensures our accountability.

Quality-based SLAs
Time and material with SLAs

Best suited for performance-driven engagements, this model tracks delivery efficiency against Service Level Agreements, offering scope flexibility and control over team’s performance without strict budget constraints.
