The Long Game of Ilya Fushman

In 2007, a 26-year-old Stanford PhD student named Ilya Fushman published a paper in Nature demonstrating quantum gates using photons trapped inside photonic crystals and quantum dots. It was a genuinely hard problem solved with real elegance. Nobody in venture capital noticed. Nobody was supposed to. That would come later.

The path from that physics lab to a partnership seat at Kleiner Perkins - one of the most iconic addresses in venture capital - runs through some of the most interesting moments in Silicon Valley history. Dropbox when it was still scrappy. Index Ventures during the Slack years. And KP during a moment when the firm itself was reinventing what it meant to be Kleiner Perkins.

Fushman grew up across three countries - Russia, Israel, Germany - before landing in the United States. He studied physics at Caltech, earned a PhD at Stanford, and then did something unusual: he stopped doing science and started building products. First at Solar Junction, where his team set world records for solar cell efficiency. Then at Khosla Ventures as a principal, getting a taste of the investment side. Then at Dropbox, as one of the company's first 75 employees, building the developer platform and Dropbox for Business from the inside.

Being employee #75 at a company that eventually goes public is not a footnote. It means you were there when the product was still a bet - writing code, running experiments, shipping features that millions of people would eventually use. Fushman ran product for both the consumer and business lines. He understands what "scale" means not as a PowerPoint metaphor but as a technical and organizational reality he personally navigated.

"Venture is like being on a swim team, not a soccer team."
- Ilya Fushman, Kleiner Perkins Partner

In 2015, Index Ventures - the pan-European firm known for backing Dropbox, Robinhood, and Figma - made Fushman its first new General Partner in five years. That's a long hiring bar. The mandate was to build Index's presence in the enterprise software and infrastructure markets, and he delivered: Slack (before Salesforce paid $27.7B for it), Intercom, KeepTruckin (now Motive), CultureAmp, Optimizely. The vintage looks different now than it did at the time.

When Kleiner Perkins came calling in 2018, it made a specific kind of sense. KP had spent years reconstituting itself - shedding the growth-stage experiments that had diluted its identity, refocusing on early-stage bets, and rebuilding around partners with deep operational credibility. Fushman fit that template precisely: someone who had built products, sat on boards, and - critically - understood the actual mechanics of the enterprise software market from the inside.

At KP, the portfolio reads like a curated argument about what the next decade of enterprise looks like: Rippling (HR and IT infrastructure), Harvey (AI for legal work), Motive (AI for fleet and physical operations), Loom (async video, acquired by Atlassian), Robinhood (financial infrastructure). These aren't scattered bets. They share a thesis about companies that use technology to restructure the operational backbone of industries that have been slow to change.

In early 2024, when Kleiner Perkins announced $2B in new capital across the KP21 and Select III funds - explicitly focused on AI - Fushman was on stage explaining the moment. More than 80% of pitches to KP now involve AI, he noted. That's not a trend to surf. That's the water the firm swims in.

His personal motto - "per aspera ad astra," through hardship to the stars - was apparently chosen before the resume got impressive. It describes a sensibility more than a career arc: someone who treats difficulty as part of the path, not an obstacle to it. Whether that comes from growing up across three cultures, navigating the gap between physics and product, or simply watching enough founders struggle through the hard parts, it's consistent with how people who've worked with him describe his style. Direct. Curious. Willing to stay with the difficult question longer than most people are comfortable with.

From Kazan to Sand Hill Road

The biography that reads easily on paper was anything but linear in real life. Ilya Fushman was born in Kazan, Russia - in what was still the Soviet Union - and grew up moving between countries as his family relocated across Europe and the Middle East before settling in the United States. He arrived at Caltech speaking multiple languages and carrying a curiosity about the physical world that made the sciences feel less like a discipline and more like a habit.

At Caltech, he worked on single-molecule biophysics, microfluidics, and computational fluid dynamics. The thread through all of it: systems that are hard to observe directly, where the only way to understand what's happening is to build tools that let you see past the noise. That same sensibility - build the instrument before you try to measure - shows up consistently in how he approaches investing.

His Stanford PhD focused on quantum computing and semiconductor physics. The quantum computing paper published in Nature in 2007 was genuine scientific work: demonstrating that quantum gates could be implemented with high fidelity using photons and quantum dots in photonic crystals. It solved a real measurement and control problem that had stymied other researchers. He was 26.

After Stanford, he made the jump to industry - first at Solar Junction, where his team set world records for solar cell efficiency, then to Khosla Ventures for a brief principal stint, then to Dropbox. The Dropbox years were formative in a different way than the physics years: he wasn't solving equations, he was solving org charts and product roadmaps, figuring out how to get engineers and designers and salespeople moving in the same direction at speed.

01
Kazan → Rehovot → Frankfurt → NYC → Pasadena → Bay Area. Multiple countries before age 18. Fushman's global early life shaped a perspective that most domestic-only investors simply don't have.
02
Solar Junction world record. Before VC, he led the team that built the most efficient multi-junction solar cell ever recorded at the time. Clean energy hardware. Before that was fashionable.
03
Dropbox for Business was not obvious in 2013. Consumer file sync as enterprise infrastructure? Fushman helped make that argument - and build the product that proved it.
04
"Per aspera ad astra." Through hardship to the stars. His chosen motto has roots in Roman Latin and the early space program. Also a pretty good description of early-stage investing.
05
Business Insider's Silicon Valley 100 in 2014. Ranked #84 on their list of most influential investors - while he was still at Dropbox, before he had even taken a GP seat.

When 80% of Pitches Say AI

80%+
of pitches to Kleiner
Perkins now involve AI
(as of early 2024)

In February 2024, Fushman sat on stage with Mamoon Hamid at a StrictlyVC event and said the quiet part out loud: more than 80% of the pitches coming through Kleiner Perkins' door now involve AI in some way. Not a niche. Not a category. The entire pitch landscape had shifted.

That context matters for understanding his portfolio. The KP21 and Select III funds raised in 2024 - $2 billion in total - were explicitly built around this moment. The thesis is not that AI is interesting. The thesis is that AI is re-platforming entire industries, and the value accrues to companies that own mission-critical workflows in those industries.

Harvey is the clearest expression of this: a company that does the actual work of a junior lawyer - research, drafting, analysis - and has been adopted by firms like Allen & Overy and Paul Hastings. Rippling is another: it treats HR and IT data as infrastructure, then layers AI services on top. These aren't "AI-enabled" companies in the marketing sense. They're fundamental rewrites of how industries operate.

Fushman's physics background may actually matter here. He trained in systems where you cannot observe the ground truth directly - you infer it from signals. That's precisely what AI-driven enterprise software does: it infers the state of an organization, a legal case, a fleet, from indirect signals and then acts on them. The technical intuition transfers.
