Notation Capital Research

Investment Thesis

Notation Capital is the first dedicated pre-seed venture fund in New York, focused on backing product-obsessed founders on day zero—when the idea is just taking shape. The firm's mission is explicit: to increase the odds of success for founding teams that are building fundamentally new experiences for customers, often in fringe or overlooked markets that can become mainstream.

Rather than being thesis-driven in the traditional sense, Notation looks for companies that represent early-stage experiments with compelling teams, clear founder-market fit, and innovative products or business models. They specialize in working with founders before market validation is obvious, often investing as early as an idea with a go-to-market strategy.

Stage and Check Size Focus

Notation is a pure pre-seed investor:

  • Primary stage: Pre-Seed ($250K - $750K), typically leading or co-leading the first institutional round
  • Average check size: $800K (according to their operating manual)
  • Secondary stage: Occasionally "institutional seed" companies (Series A funding for teams with product-market fit), representing ~1-2 investments per year
  • Check size range: $250K - $750K minimum threshold

The firm has explicitly avoided the trap of "simply raising as much money as possible," preferring disciplined founders who raise capital thoughtfully and appreciate resource constraints.

Fund History and Size

Notation has closed three funds:

  1. Notation I (2015): $7.9M proof-of-concept fund, invested in 28 pre-seed companies
  2. Notation II + Notation II-A (LP community fund): $27.8M combined
  3. Notation III + Notation III-A (LP community fund): $46M total (includes community LP fund component)

Fund III began deployment in 2021 and has made 20+ investments as of mid-2024. Notable recent deployments include a $5-10M+ check into Photon Health (August 2024), described as "their largest check in a decade," signaling continued active deployment.

Investment Decision Framework

Team: High-integrity leaders with clear communication, complementary skills, builders by nature (technical DNA, product-focused), unique insight and passion for specific problem
