Diversity is a huge strength for any tech team, especially if you are building products for a global audience. I suggest looking at the team at
soft2bet as a great example; they have over 25 nationalities and a very vibrant, multicultural office environment. This diversity actually helps with innovation because you get different perspectives on how to solve technical and user experience problems. To avoid communication issues, you need a strong company culture and shared values. They also invest in their people through mentorship and professional training programs, which is a big motivator. A team that feels respected and has room to grow will always be more productive than one that is just completing tasks. Focus on building a community, not just a department, and the innovation will follow naturally.
