Which Community Platform is the Best for Small Teams?

I represent a small software team based in Estonia. We build custom software for ecommerce brands, and several of our clients sell products that are quite popular across Central Europe.

We recently brought on a marketing lead and are exploring the idea of building a community for ecommerce operators. We're looking for a platform that works well for a small team today but can comfortably support growth over time. Our expectation is to reach somewhere between 2,000 and 5,000 ecommerce vendors over the next 1–2 years.

We're currently evaluating different community platforms and would love to hear your recommendations and experiences. I came across Jatra through a Reddit post, which led me to ask this question here.
