Abax is a good fit if

  • Your fund is under $50M, or you're launching Fund I at that size
  • You want one flat, published price instead of a custom AUM quote
  • You'd rather not pay more in admin fees as your portfolio marks up
  • You want to be onboarded in days, not months

Carta is a good fit if

  • Your fund is well above $50M, or spans venture, PE, and credit
  • You want fund administration bundled with cap table and 409A tools
  • You're already deep in the Carta ecosystem for other products
