After ChatGPT's release, Oseary and Ashton Kutcher believed foundational AI models would become long-lived infrastructure comparable to the enduring app-era companies they had backed. They treated the opportunity as a narrow category window rather than a conventional multi-year deployment cycle. Their pitch specified a foundational-model fund, a three-month window, and a plan to deploy 80 percent of the capital during that period. Prospective limited partners therefore opted into the speed and concentration before committing money. Oseary paired that mandate with intensive research, trusted signals from Salesforce Ventures and a headhunter observing talent movement, founder meetings, and access work. The method makes speed accountable by declaring the thesis, timing, and allocation up front; urgency follows the mandate rather than replacing research.
Origin
Oseary and Kutcher created the approach after ChatGPT's November 2022 launch and used it to build a foundational AI model fund in early 2023.
Core principles
- 01A platform shift can create a short investment window
- 02The fund's timing and concentration belong in the original pitch
- 03Investors should opt into the exact thesis rather than learn it later
- 04Research and trusted signals identify the strongest candidates
- 05Rapid deployment is rational only when the window is part of the thesis
How to run it
- 1
Recognize the platform shift
Determine whether a new capability can become foundational infrastructure rather than a temporary product wave. Oseary compared foundational AI models with durable app-era companies such as Uber, Airbnb, and Spotify.
Pro tip Use prior platform shifts to test the expected duration of the new layer.
Watch out Excitement about a launch is not by itself a durable infrastructure thesis.
- 2
Define the window
Specify how long attractive access is likely to remain and how much capital should be deployed inside that period. The team chose three months and an 80 percent deployment target.
Pro tip Write the timing into the mandate before fundraising.
Watch out Do not invent urgency after capital has been raised.
- 3
Raise aligned capital
Present the complete thesis, window, and deployment rate to prospective limited partners. Let investors opt in or out based on that exact mandate.
Pro tip Make unusual concentration and speed explicit in the pitch.
Watch out Changing the strategy after investors commit breaks alignment.
- 4
Triangulate candidates
Combine direct product conviction with research, expert investors, and labor-market signals. Oseary followed Salesforce Ventures' enthusiasm and learned where sought-after talent was moving.
Pro tip Look for independent signals from capital, customers, and talent.
Watch out A trusted introduction should begin diligence, not end it.
- 5
Secure access and deploy
Meet the founders, communicate the contribution you can make, and execute within the predeclared window. Track deployment against the mandate rather than stretching the fund into a different strategy.
Pro tip Use differentiated access and operating value to improve allocation prospects.
Watch out Fast deployment without access to category leaders weakens the original thesis.
In the wild
After ChatGPT launched, Oseary and Kutcher pitched a fund limited to foundational AI models. They told prospective investors that the opportunity window was three months and that 80 percent of the fund would be deployed in that period.
→ The mandate secured positions including OpenAI and Anthropic while making the unusual deployment speed explicit to investors.
Oseary heard that Salesforce Ventures was bullish on Anthropic and separately learned from a headhunter that talent was concentrating there. He asked Salesforce investors for an introduction and met Dario and another colleague at his home.
→ The fund invested in Anthropic after multiple independent signals and a founder meeting.
Common mistakes
Hiding the speed from investors
The three-month window and 80 percent deployment target were the original pitch. Disclosing them only after raising capital would remove informed opt-in.
Using urgency instead of a thesis
The team's speed followed a specific belief about foundational models and a short access window. Urgency alone does not justify concentrated deployment.
Relying on one signal
Oseary combined product conviction, investor research, talent movement, introductions, and a founder meeting rather than using a single endorsement.
Is it for you?
Best for
It is best for experienced investors with strong access, a researched category thesis, and a genuinely time-limited market opportunity.
Not ideal for
It is not ideal for broad funds, uncertain theses, or teams using urgency to avoid diligence.
From the transcript
“We told people we have a three-month window.”
“We're going to deploy 80% of the money within the next 3 months.”
“Yeah. Opt in or opt out.”
