Minimal CRM for indie hackers and solo founders

Full CRMs like HubSpot and Pipedrive are overkill for a solo founder managing 20-50 customer relationships. I need something dead simple: a list of contacts, a notes field, a last-contacted date, and a follow-up reminder. No pipelines, no deal stages, no dashboards. Just contacts and context. Ideally with a command-line interface or Raycast extension.
