What Are the Current B2B SaaS AI Startup Investment Criteria for 2026?

[calebhartley]

The funding landscape has shifted significantly this year, and I am trying to refine my pitch deck to align with what VCs are actually looking for right now. Does anyone have a breakdown of the b2b saas ai startup investment criteria regarding gross margins and data moats? It seems that just having an "AI wrapper" is no longer enough to secure a Seed or Series A round.

Specifically, I am curious if investors are prioritizing high NRR over rapid customer acquisition in the current b2b saas ai startup investment criteria checklists. If you are a founder who recently closed a round, did the partners focus more on your proprietary dataset or your integration depth with existing enterprise legacy systems?
