Daniel Gross Net Worth 2026: SSI Co-Founder & AI Grant

Daniel Gross — Israeli-American technology executive and investor — is one of the most distinctive figures in modern AI. Co-founder of Safe Superintelligence Inc. (SSI) with Ilya Sutskever and Daniel Levy, founder of Cue (acquired by Apple in 2013), former Apple AI/ML search lead, ex-Y Combinator partner, and co-founder of AI Grant with Nat Friedman, Daniel has built one of the most varied and influential careers in modern technology investing and entrepreneurship. As of 2026, Daniel Gross’ net worth is estimated at approximately $500 million to $1 billion or higher, with significant upside as SSI scales.

Daniel’s significance to the modern AI landscape combines four distinct dimensions: operating experience (Apple AI lead), investing experience (Y Combinator partner and prolific personal investor), AI startup founding (SSI co-founder), and ecosystem-building (AI Grant). Few people in technology operate at this scale across all four dimensions simultaneously.

Who is Daniel Gross?

Daniel Gross was born in Jerusalem, Israel, in approximately 1991. He notably did not attend university, instead moving to Silicon Valley as a teenager to pursue technology entrepreneurship. He participated in the Y Combinator startup accelerator with his first company Cue (then called Greplin), making him one of the youngest founders ever accepted into the program at the time.

Cue was a personal-information search startup that built tools for indexing and searching across user data sources. Apple acquired Cue in 2013 for a price reportedly in the tens of millions of dollars. Following the acquisition, Daniel joined Apple as a senior figure in their AI and machine learning search efforts, eventually leading those teams.

He left Apple in 2017 and joined Y Combinator as a partner, where he focused on AI-related startups for several years. After leaving YC, he became a prolific personal angel investor in AI companies, frequently co-investing with Nat Friedman. The two formalized their AI investing partnership through AI Grant in 2026, providing seed-stage funding and infrastructure access to AI startups.

In June 2024, Daniel co-founded Safe Superintelligence Inc. (SSI) with Ilya Sutskever (OpenAI co-founder and former Chief Scientist) and Daniel Levy (former OpenAI research lead). SSI’s stated mission is to build safe superintelligent AI systems. The company has reportedly raised significant funding at a multi-billion-dollar valuation.

How Daniel Gross accumulated his net worth

1. Cue acquisition by Apple (2013)

The Apple acquisition of Cue in 2013 was Daniel’s first major liquidity event. The reported price was in the tens of millions of dollars, with Daniel as a co-founder receiving a meaningful share. The acquisition price plus subsequent Apple stock awards/RSUs during his 2013-2017 tenure plausibly contributed $30M-$80M to his accumulated wealth.

2. SSI co-founder equity

Safe Superintelligence Inc. has reportedly raised significant funding at multi-billion-dollar valuations. As one of three co-founders alongside Ilya Sutskever, Daniel’s equity stake plausibly carries $300M-$700M in mark-to-market value, with substantial illiquidity discounting given the company’s young stage. This is the largest single component of his current net worth.

3. Angel investments / direct portfolio

Daniel has been one of the most prolific personal angel investors in AI for the past several years. His portfolio includes positions in many of the most-valuable AI startups (some via AI Grant, others personally). Cumulative mark-to-market value of his angel portfolio is plausibly $100M-$300M.

4. AI Grant economics

AI Grant, the seed-stage AI fund Daniel co-founded with Nat Friedman, generates economics through its portfolio investments. As a partner, Daniel’s share of carry and management fees on AI Grant’s portfolio plausibly contributes a meaningful supplemental income line, though most of the value is illiquid until portfolio exits occur.

5. Y Combinator equity / vested compensation

Daniel’s 2017-2021 tenure as a Y Combinator partner included standard partner compensation (cash + equity in the YC portfolio companies he sponsored). Cumulative value plausibly contributes a low-eight-figure component.

Net worth estimate breakdown

Component	Estimated Value
SSI co-founder equity (illiquidity-adjusted)	$300M – $600M
Cumulative angel investment portfolio (mark-to-market)	$100M – $250M
Apple stock vested + Cue acquisition proceeds (post-tax)	$40M – $100M
AI Grant partner economics (illiquid portion)	$30M – $80M
YC partner compensation residuals	$10M – $30M
Public-equity portfolio, cash, real estate	$30M – $80M
Total estimated net worth	$500M – $1B+

Common misconceptions

“Daniel Gross is worth $5B+.” This figure circulates online but is not supported by reasonable equity assumptions. SSI’s co-founder equity, even at top-of-band valuations, is unlikely to imply more than $1B at current valuations after illiquidity adjustments.

“Cue made Daniel rich.” The Apple Cue acquisition was meaningful but not transformational at the deal value reported. Daniel’s wealth is the product of decades of layered compensation events — Cue, Apple stock, YC partnership, AI Grant economics, and now SSI equity.

“He’s primarily an investor.” Daniel’s career has spanned operator (Cue founder, Apple AI lead), investor (YC partner, AI Grant co-founder), and now founder again (SSI co-founder). The label “investor” understates the operating component of his career.

“AI Grant is just a small fund.” AI Grant has built a meaningful portfolio of AI startups since its 2023 founding. The carry economics on a successful AI seed fund can produce nine-figure-plus payoffs over time.

Daniel Gross compared to other top AI founders and investors

Person	Role	Estimated Net Worth (2026)	Primary Value Driver
Daniel Gross	SSI co-founder + AI Grant + angel investor	$500M – $1B+	SSI equity + portfolio investments
Nat Friedman	AI Grant + ex-GitHub CEO + investor	$300M – $500M	GitHub sale + AI investments
Dario Amodei	Anthropic CEO	$1.5B – $3B	Anthropic equity
Aravind Srinivas	Perplexity CEO	$1B – $2B	Perplexity equity
Mira Murati	Thinking Machines	$200M – $500M	OpenAI residual + Thinking Machines
Ilya Sutskever	SSI co-founder, ex-OpenAI Chief Scientist	$1B+	SSI equity + OpenAI residual

Daniel sits in the upper portion of the AI founder/investor wealth tier, with structural diversification across operating roles, investing positions, and now a major frontier AI lab co-founding stake.
