Is there any scope for price tiers for larger customers as the costs soon outweigh the value once you get into the 10's of thousands of users? e.g. take a company of 40,000 staff at 2$ a head this is nearly 1 million a year. I am sure i can hire a team and run infra for this level. Happy to hear some other metric to justify this but as you know everyone is under cost pressure to save money and I can't see how to save money at scale with this product... Please help 🙂
