Tanmai, their CEO, gave a response in the Discord on this question a few weeks ago:
"The pricing depends on your team/org: what features you’re using Hasura and the uptime/response SLA that you need. If you have something running with Hasura already feel free to setup a chat with the team to get a sense of the pricing. However we will have something launching for self-serve style pricing soon for a managed HA / auto-scalable Hasura with Pro features."
I believe it's priced on a per-feature basis, so they're likely to work with you depending on what your particular needs are.
