Cheyenne Ventures Research
Investment Thesis
Cheyenne Ventures, founded in 2008 by Gregory Eaton and Jay Fulcher, backs "transformational companies that redefine and re-imagine a new generation of AI infrastructure, cybersecurity, cloud management, SaaS, consumer products, and health innovations." The firm describes itself explicitly as "people-specific, not sector" — it prioritizes visionary founders with integrity and execution capability over any single industry vertical, and its current portfolio spans cybersecurity/AI-infra platforms, enterprise SaaS, digital health, and a handful of consumer products companies.
Stage Focus
Cheyenne is an expansion/growth-stage investor. It does not typically lead pre-seed or early seed rounds; instead it enters at Series A extension through growth rounds, often re-upping into existing portfolio companies (e.g., Abstract Security's Series A extension, Signos's growth raise). The firm positions itself as "Selective, Nimble, and Founder-Focused" — smaller and more concentrated than mega-funds, with a deliberately discriminating deal-selection process.
Check Size
Specific check sizes are not publicly disclosed. Given the growth-stage focus and co-investment pattern alongside firms like Atlantic Vantage Point, Crosslink Capital, and Rally Ventures, individual checks are likely in the multi-million-dollar range as part of $15M-$50M+ rounds, but this should be treated as inferred rather than confirmed.
Lead Tendency
Cheyenne both leads and co-invests. Marketing language states the firm "leads investments or co-invests alongside top-tier VCs," and its 2026 activity shows both patterns: it co-led Abstract Security's $25M Series A extension alongside Atlantic Vantage Point, while joining as one of several participants in Signos's $20M raise (led by GV/Dexcom/Blue Cross Blue Shield of Alabama).
Recent Activity
Fund status is unclear (no disclosed fund name, size, or vintage), but portfolio-company activity through 2026 indicates the firm is actively engaged with its book:
- July 2026: Co-led Abstract Security's $25M Series A extension (380% YoY revenue growth, 3x prior valuation).
- May 2026: Participated in Signos's $20M raise alongside GV, Dexcom, and Blue Cross Blue Shield of Alabama, tied to an expanded Dexcom Stelo partnership.
- May 2026: Portfolio company AuthMind appointed Silvio Pappalardo (ex-Permiso Security, ex-QuintessenceLabs) as Chief Revenue Officer.
- July 2026: Portfolio company Chunk Foods expanded into Sprouts (~480 stores) and H-E-B, on top of an ongoing nationwide Whole Foods rollout.
- July/August 2026: Portfolio company ArmorCode joined Anthropic's Cyber Verification Program, gaining verified access to Claude models for defensive security research.

Decision Process
Not publicly documented, but with only two senior investment leads (Eaton and Fulcher) plus a venture partner, this reads as a small-partnership decision process rather than a large investment committee.
Founder Preferences
The firm's stated criteria are explicitly founder-first: "visionary founders with integrity and the ability to execute" rather than a specific sector or business-model checklist.
Geographic Focus
Headquartered at 2925 Woodside Road, Woodside, CA 94062 (San Francisco Bay Area). Portfolio is overwhelmingly US-based, with one portfolio company (Chunk Foods) noted as Israeli-founded / NY-headquartered.
