Ian Hathaway, partner at OpenAI Startup Fund, is one of the 100 leading corporate venturing professionals in our 2026 Powerlist.
When Ian Hathaway stepped into a leadership role shaping the OpenAI Startup Fund, replacing CEO Sam Altman, he inherited something unusual: not merely a venture vehicle, but a strategic instrument tethered to one of the fastest‑scaling technology platforms in history.
A relative unknown outside Silicon Valley’s inner investing circles, with only four years at VC firm Haystack beforehand, Hathaway now finds himself tied to what could become one of the most spectacular venture outcomes ever recorded. The fund was an early backer of Cursor — the AI coding startup built by Anysphere — leading its $8m seed round in October 2023. If SpaceX/xAI proceeds with its call option to acquire Cursor for $60bn, it would mark the largest VC‑backed mergers and acquisitions deal on record and deliver an estimated 10,000‑times return for OpenAI, according to Dealroom data.
OpenAI itself may still feel bruised, having attempted to buy Anysphere/Cursor in 2024/25 to consolidate its position in coding tools — the most commercially significant AI use case to date. The strategic logic is clear. Winning in agentic coding requires control of three layers: compute, models and distribution. Anthropic, OpenAI and Google each own the first two. Cursor provides the third, giving OpenAI a defensive moat around the compute and model infrastructure powering ChatGPT.
Given coding is now the most important market in AI — ahead of chatbots, search and image generation — Cursor’s explosive growth to $2bn in annualised revenue explains both its valuation and SpaceX’s desire to secure the deal following its planned $1.75tn flotation in June.
Yet Hathaway’s portfolio extends far beyond Cursor. The $175m OpenAI Startup Fund has made more than 20 investments since early last year, targeting early‑stage AI companies in healthcare, law, education, energy and infrastructure. Its backers include Microsoft and other OpenAI partners, though OpenAI itself is not an investor and remains governed by the OpenAI Nonprofit.
Recent deals include Worktrace AI’s $9.3m seed round, Harvey’s $300m raise for AI‑native legal workflows, and Ambience Healthcare’s $243m round focused on clinical administration. Each sits in a regulated, high‑margin domain where distribution, trust and integration matter as much as model performance.
Founders increasingly describe the fund as both investor and technical partner, collapsing the traditional gap between capital and commercial traction. But this tight coupling to OpenAI’s infrastructure also raises questions about long‑term independence. Hathaway’s challenge is to balance ecosystem influence with founder autonomy.
In a crowded CVC landscape, the OpenAI Startup Fund is emerging as something different: not just capital with a strategic angle, but strategy delivered through capital.
