They look for deeply technical founders building software products who want hands-on engineering support, not just capital and advice.

Exclusion Criteria

Not a fit for non-technical founders, consumer apps, hardware, life sciences, or founders who want passive investors. They are builders first and expect to be deeply involved.

Commit Capital Research

Investment Thesis

Commit Capital is a hands-on pre-seed and seed-stage venture fund founded by a team of five early Palantir engineers (2005/2006 cohort) who have worked together for over 15 years. Their core belief is that the best way to help startups is not through advice from the sidelines but by embedding directly with engineering teams. Four of the five partners were among the earliest engineers at Palantir, where they led commercial product development for a decade. After Palantir, they became the founding engineering team of Hexagon Bio, a biotech startup, demonstrating their ability to go from 0 to 1 across different domains.

The firm's tagline — "Investing in exceptional founders, coding beside them" — encapsulates their differentiated approach. They help portfolio companies ship faster by embedding with engineering teams, thought-partnering on roadmap and architecture decisions, and helping create and run recruiting processes. They position themselves explicitly as builders who happen to invest capital, not as traditional "how-can-I-be-helpful" VCs.

Sector Focus

Commit Capital focuses on software companies, with a strong emphasis on:

  • AI infrastructure and developer tools (context engines, observability)
  • AI applications (reinforcement learning, AI-native platforms)
  • Developer tools and infrastructure
  • Enterprise software with deep technical foundations

Their portfolio reflects a clear orientation toward AI-native infrastructure and developer tooling, particularly platforms that enable engineering teams to build and operate AI systems more effectively.

Stage Focus

The fund primarily targets:

  • Pre-seed investments
  • Seed investments

Their website prominently positions them as "Pre-seed Software Investments," though their disclosed portfolio includes seed-stage deals as well. They appear to prefer being early — investing when founders are still in the building phase.

Check Size

Specific check sizes are not publicly disclosed. Based on the stage focus (pre-seed and seed) and the size of typical pre-seed/seed rounds in their focus areas, estimated check sizes are likely in the $250K–$2M range for pre-seed and $1M–$4M for seed rounds.

Lead Tendency

Given their deep technical involvement with portfolio companies (embedding with engineering teams, architectural guidance), Commit Capital likely leads or co-leads rounds at the pre-seed and seed stage. Their hands-on approach suggests they take meaningful ownership positions.

Recent Activity

Commit Capital is actively deploying from Fund I (San Francisco-based, per PitchBook). Recent disclosed investments include:

  • Cortex / HydraDB (Seed) — Context and memory infrastructure for AI agents. HydraDB is an "AgentDB" that provides context engineering, relationship-aware retrieval, and memory layers for AI systems. The company has paying customers and enterprise-ready features.
  • Sazabi (Seed) — AI-native observability platform for fast-moving engineering teams. Features autonomous alerts, conversational debugging, and tight integration with coding agents like Claude Code, Codex, and Cursor. Backed by notable angel investors from LangChain, Anthropic, Vercel, Replit, Homebrew, and others.
  • Stealth Company (Seed) — Building in AI reinforcement learning.

All three portfolio companies are in the AI/developer tools space, confirming a clear thematic focus.

Portfolio Highlights

The disclosed portfolio is small but thematically cohesive:

  • Cortex (HydraDB) — Solving the context engineering problem for AI agents. Positioned as a replacement for vector databases with relationship-aware retrieval. Pricing from $249/mo to $5,000+/mo enterprise tier.
  • Sazabi — Taking on Datadog and traditional observability with an AI-native approach. Strong angel investor roster including Harrison Chase (LangChain), Lance Martin (Anthropic), Matt Palmer (Replit), Hunter Walk (Homebrew), and Rotem Weiss (Tavily).
  • Stealth (AI RL) — Undisclosed company working on AI reinforcement learning.

Team

All five partners share deep Palantir roots and technical backgrounds:

  • Andrew Aymeloglu (Andy), General Partner — Led Palantir commercial product development for a decade. Stanford CS. Also co-founded Hexagon Bio (biotech). Holds multiple patents from Palantir work. Based in Austin, TX. Endorsed by Joe Lonsdale (Palantir co-founder) who called him "a genius who resides a level above other geniuses."
  • Laura Yao, Partner — Long-time investor in developer tools and infrastructure. Yale Economics/Math. Brings the investment experience to complement the engineering-heavy team.
  • Javier Lopez, Partner — Engineering generalist and former Head of People at Palantir. Stanford CS. Brings both engineering and organizational/recruiting expertise.
  • Kevin Simler, Partner — Engineering generalist, hiring strategist, and published author. Berkeley CS. Known for writing about technology and human behavior.
  • Brandon Burr, Partner — Rapid prototyper with a product and user focus. Stanford CS.

Decision Process

With five partners who have worked together for 15+ years, Commit Capital likely operates as a tight partnership with consensus-driven decisions. The small team size and long-standing relationships suggest fast decision-making without formal investment committee processes.

Founder Preferences

Commit Capital explicitly seeks:

  • Deeply technical founders who want to move faster
  • Founders who value hands-on engineering support over advisory
  • Teams building software products, particularly in AI infrastructure and developer tools
  • Founders comfortable with investors who embed directly with their engineering teams

Geographic Focus

Fund I is based in San Francisco, and the team has Bay Area roots (Stanford, Berkeley). Andrew Aymeloglu appears to be based in Austin, TX. Likely focused on US-based startups, particularly SF Bay Area and Austin.
