Scribble Ventures Research

Investment Thesis

Scribble Ventures is an AI-native venture capital firm founded by product and go-to-market leaders from OpenAI, Meta, Twitter, and a16z. The fund backs the world's best AI native founders and helps them reshape the world for the better. Their core conviction is that "AI companies are built differently" and they focus on founders who demonstrate the ability to do things that are extremely unlikely.

  • AI-native software products
  • Generative AI applications
  • AI agents and automation

The fund operates with a specific mandate: go wide on product, deep on go-to-market (GTM).

Stage Focus

Scribble is a pre-seed and seed-stage investor with optional Series A participation. They position themselves as "most often the first backer" and invest selectively to provide maximum time and effort at critical early stages.
