Epsilon Ventures Research Document
Investment Thesis
Epsilon Ventures believes in backing the outliers — small teams with exceptional speed, focus, and product-market fit. Founded by experienced entrepreneurs and investors, the fund is built on the conviction that big outcomes are born from small beginnings. They position themselves as "first to back the outliers" with a philosophy centered on smallness: small teams, small focused markets, and the tightest possible product-market fit.
The fund's core belief is that small teams move with clarity and speed, narrow markets allow founders to dominate early and expand with leverage, and elegant, tightly-built solutions are easier to test, scale, and loved by customers.
Sector Focus
Epsilon Ventures invests across sectors with a particular focus on:
- Artificial Intelligence and machine learning applications across verticals
- Data infrastructure and analytics platforms
- Enterprise software and productivity tools solving real workflows
- Marketplace and e-commerce innovation
- Consumer applications built on emerging technology
- Developer tools and infrastructure
The fund explicitly values elegantly-built solutions that solve real problems with minimal unnecessary complexity. They seek companies that combine technical rigor with market focus.
Stage Focus
Epsilon Ventures is definitively a preseed and early-stage investor with strong conviction around getting in at the earliest moments. Their stated focus is on:
- Pre-seed: Concept stage, first team formation, founder with vision
- Seed: Initial product built, early customer traction or strong validation
The fund positions itself as willing to move quickly and operate at founder speed, backing companies before they have significant traction or market validation.
Check Size
Based on their "small checks" positioning and emphasis on preseed and seed stage, estimated check sizes are:
- Pre-seed: $250K-$500K for founding teams with strong conviction
- Seed: $500K-$1.5M for teams with working products and initial validation
- Typical check size: $300K-$800K
The fund maintains dry powder for follow-on investments in successful portfolio companies.
Lead Tendency
Epsilon positions itself explicitly as a "first-check investor" willing to lead or co-lead early-stage rounds. They write early checks before consensus forms and bring more than capital — they contribute data, operational experience, and hands-on support. Their partnership model emphasizes board involvement and active portfolio support.
