I'm looking for a VPS for a small CRM that we're launching for customers in Poland. The initial user base will be relatively small, but the application will have a PostgreSQL database and several background workers.

My budget is around €25–30/month, and I'd prefer a server in Poland to keep latency low for local users.

Hostpro.com is one of the providers I'm currently considering. Their KVM VPS plans with NVMe storage look suitable for a database-driven application, and having root access would let me configure the environment myself.

Would 4 vCPUs and 8 GB RAM be enough for the first stage?
