About Halcyon Ventures

Halcyon Ventures is a mission-driven VC firm dedicated to building a safe, secure, and resilient world in the era of transformative AI.

Halcyon's advisors and investors include:

  • OpenAI’s Head of Trustworthy AI
  • OpenAI’s former Head of AGI Readiness
  • DeepMind’s CISO
  • US Navy CTO
  • Former President of YCombinator

Our mission is to help excellent entrepreneurs maximize the impact of their work, and to be positive stewards of the AI safety and security industries. We invest at pre-seed, seed and Series A. We also sometimes incubate companies.

Halcyon’s Founder and Managing Partner is Mike McCormick. Mike has spent nearly a decade in venture capital, most recently as a partner at $1.5bn+ VC firm, GPV, where he was an early stage backer of several unicorn companies.

Halcyon Ventures is partnered with Halcyon Futures, an entrepreneurial nonprofit that helps leaders take on ambitious projects in AI safety and security. In the last 18 months, we’ve helped our members start a dozen new orgs and companies, which have collectively raised $200m+ in funding. These include Goodfire, Lucid Computing, Transluce, Seismic, and Fathom.

About the Role

We’re looking to bring on an investment team member. This person will be a right-hand and thought partner with Mike, helping to build and run all aspects of the firm.

We’re open to a range of experience levels, from scrappy early-career professionals to seasoned investors or startup operators ready for a Principal or Partner-level role.

What matters most is your passion for our mission and your ability to contribute to our success.

What you’ll do
  • Source, evaluate and execute investments
  • Support portfolio companies and founders
  • Help shape the firm’s strategy
  • Develop investment theses and drive research projects
  • Build a great network and serve as an ambassador for the firm
  • Help host and attend events
  • Support with running the firm’s operations
Attributes of ideal candidates
  • Deep interest in the coming wave of powerful AI and its implications for society
  • 2-10 years of relevant experience relating to AI, startups or venture capital
  • Strong network with founders, particularly in our focus areas
  • Highly motivated by Halcyon’s mission
  • Thoughtful, kind, and high EQ
  • Entrepreneurial vibe – energized to create your own opportunities and run with projects independently
  • Technical experience like software engineering, AI model training or cybersecurity
  • You live in San Francisco or are excited to move there

We don’t necessarily need candidates to meet every single one of these criteria, so if you don’t have them all, but still think you’re a good fit, please apply!

Benefits
  • Opportunity to build relationships with leaders in AI, AI security, startups, VC, etc.
  • Competitive salary and bonuses
  • Excellent health, dental and vision insurance
  • 401(k) plan with a company match up to 5% of salary
