Airtable is really interesting for views, groupings, sorts, and possible filters. It also has a powerful and well-documented API. It's a good low-code tool for bootstrapping project ideas.
Big fan of Airtable. We use it at Weekend Fund to manage our CRM of founders, LPs, etc. and pipeline of companies we're speaking with.
There are purpose-built CRMs for similar use cases but I like that Airtable is generalized and flexible to adapt to our needs. It also has several integrations that trigger automations (via Zapier) for various workflows.
