Hey Ibrahim,
Really cool what you've built - an open-source Gong alternative at under $50/month is a no-brainer for early stage GTM teams.
On your questions - for enrichment providers I'd start with Clearbit and Apollo since most GTM teams are already using at least one of them. Clay integration would also be huge given how many teams are running their workflows there.
For call ingestion I'd go the notetaker route first - connecting Fathom or Fireflies is way less friction than shipping your own bot. People already have their preferred notetaker set up so meeting them there makes adoption way easier.
If you still need any help, you can always text me!
