Caffeinated Capital Research

Investment Thesis

Caffeinated Capital is a San Francisco and New York-based venture firm founded by Howie Liu (CEO/Co-Founder of Airtable) and operates under a philosophy of long-term partnership with founders. The firm explicitly rejects the hype cycle, positioning itself as offering founders "the luxury of long-term thinking." They support founders building "category-defining companies across all sectors that will last for lifetimes."

The firm is aggressively optimistic about the future and takes genuine early-stage risk alongside founders, committing to be a lifetime partner investing time, effort, and capital throughout the company lifecycle.

Stage Focus

Caffeinated Capital is primarily a seed and Series A investor, though they provide follow-on capital through later stages:

  • Seed: Primary focus, often co-leading or leading rounds
  • Series A: Leading rounds with hands-on involvement
  • Series B through Series E: Follow-on investing in existing portfolio companies

They explicitly state they "lead seed and Series A rounds and invest throughout the life of technology companies."

Check Size

Based on portfolio analysis:

  • Seed: $1M-$3M (lead/co-lead typical)
  • Series A: $2M-$5M+ typical participation
