Factorial Capital Research
Investment Thesis
Factorial Capital is a purpose-built early-stage venture capital firm for the AI era. Led by Matt Hartman (former 10-year VC at Betaworks), the fund invests in technical founders building at the frontier of AI/ML infrastructure and AI-native applications. The firm's core conviction is that the next generation of transformative companies will be built by engineers who code, focused on solving previously technically impossible problems using recent AI breakthroughs.
Sector Focus
Factorial invests exclusively in companies built by technical founders at the intersection of AI and emerging technology:
Primary Focus Areas:
- AI/ML infrastructure (databases, vector stores, LLM tooling, observability)
- B2B SaaS powered by AI (productivity tools, enterprise automation)
- Consumer AI applications leveraging frontier models
- Data infrastructure and ETL/transformation tools
- AI safety and evaluation tools
The fund explicitly avoids non-technical founding teams and focuses on founders with demonstrated technical depth.
Stage Focus
Factorial is an early-stage specialist:
- Angel/Pre-seed: Primary focus with $500K-$1M checks
- Seed: Secondary focus, happy to participate
- Series A: Selective follow-on for strong portfolio companies
The fund emphasizes "rough prototype stage" investments - investing when founders have technical validation but before product-market fit.
Check Size
Typical investment range: $500K - $1M
- Angel/Pre-seed: $500K-$1M (primary)
- Seed: $500K-$1.5M
- Target ownership: 5-10% depending on stage
Lead Tendency
Factorial positions itself as flexible on lead vs. co-lead vs. participation:
- "We are happy to be the first yes or the last yes"
- "Lead, co-lead, or just be a part of the round"
- Strong conviction backing allows quick decisions with minimal committee
