How to choose

  1. Decide whether you need a large integrator, a product company partner or a specialist studio.
  2. Check language, time zone and on-site needs.
  3. Ask for local references and case studies.
  4. Compare local rates with nearshore and offshore teams.
  5. Agree IP ownership and data protection terms that fit local law.

Red flags

  • Prices far below the market with no clear explanation.
  • No named team, or reluctance to let you interview the people who will do the work.
  • Case studies without results, clients or links you can check.
  • Contracts that do not assign IP and code ownership to you.
  • No plan for support, documentation or handover after launch.

How we chose

These are iCreativez Technologies’ own recommendations, based on research and experience of the market. We looked at presence and reputation in the country, size and specialisation, and, where the local market is small, nearby regional companies that serve it (labelled Regional). The list is listed alphabetically, not ranked. Details such as services, prices, plans and locations change, so confirm them directly before you decide. No one paid to appear.
