Founder of Grist here (https://www.getgrist.com/):

- focus on small teams and individuals

- open source (with community contributing!)

- can be run self-managed

- portable data (lossless export in SQLite format)

- full of great features (granular access rules, formulas with python, conditional formatting, webhooks, etc etc)

If it's little-known, it's because we spend too much time building, not enough time selling.
