Navigating Our Cooperation Models

For when you have the roadmap and the process, but not the people. Tell us the skills and seniority you need, and we send shortlisted profiles. You interview; the engineer you choose joins your existing team and works under your management.

Ideal for businesses that:

Need specialized expertise without adding full-time headcount

Want to scale capacity up or down as the roadmap shifts

Need extra hands on an upcoming or in-flight project

For when you need a team that owns a product, not individuals filling gaps. You select the engineers from the profiles above; they work exclusively on your project alongside your in-house team, keeping context instead of rebuilding it every quarter.

Ideal for businesses that:

Run large or long-term projects that need consistent ownership

Want a stable team that accumulates domain knowledge

Need engineers committed to the business goal, not just the ticket

For when scope and timeline are already settled and budget certainty matters more than flexibility. We define the delivery path up front, so the cost is known before work starts.

Ideal for businesses that:

Have a set budget and a clearly documented scope

Work to a hard deadline

Run projects with defined goals and achievable milestones

For when you want a permanent extension of your engineering organization in Vietnam, your process and your tooling, running on our infrastructure and hiring pipeline across three ISO-certified centers.

Ideal for businesses that:

Are building long-term engineering capacity, not staffing a single project

Want dedicated infrastructure and a managed hiring pipeline

Plan to grow the team steadily over several years
