Tomer London

The Kid Who Coded to Help His Dad

His father's advice was specific: "No matter what, don't start your own business — it's really, really hard." This came from a man who ran a clothing store in Haifa, Israel for over 35 years. He knew the margins. He knew the late nights. He knew the weight of payroll.

Tomer London listened carefully and built three companies anyway.

The first was at age 12. His father had a problem: inventory. The store ran on memory and paper, which worked fine until it didn't. Tomer borrowed a Visual Basic 6 book from the local bookstore owner — in Hebrew — and taught himself to code. He built a system. His father bought a 386 computer specifically to run it. That was the first product review Tomer ever got, and it shipped clean.

By 11th grade, he co-founded "Writing Whiz" - software to help non-native English speakers learn proper word usage. He posted it on download.com. It got 20,000 downloads. This was 2001, and Tomer was a teenager in Israel discovering, without any formal framework, what product-market fit feels like.

The Military, Then Stanford

After high school came mandatory Israeli military service - three years in a combat unit, not intelligence. He says it was "the first time in my life I wasn't in control." For someone who had been automating things since age 12, that kind of forced stillness leaves a mark.

He studied electrical engineering at the Technion, one of the world's top technical universities, then moved to Silicon Valley to pursue graduate work at Stanford. Three things pulled him west: Steve Jobs' 2005 commencement speech about the possibility of changing reality, the story of Google's founders, and a friend's nudge. He arrived carrying the engineer's instinct that problems were solvable if you approached them with rigor.

Before Gusto, he co-founded Vizmo, a mobile self-service customer support technology company - a solution for bypassing call center wait times. The technology worked. The go-to-market didn't. He shuttered it in 2011 having learned the lesson that would define everything he built afterward: "You can have the best product in the world, but if you don't know how to sell it, you're dead."

From a Closet to 400,000 Customers

Gusto's origin story has a specific smell. Tomer and his co-founders cold-called businesses listed on Yelp, working from a walk-in closet, asking one-hour open-ended questions about payroll. They weren't pitching. They were listening for the emotional signal - either "where do I sign up" or "this is absolute garbage" - because both are useful. Polite maybes, he learned, kill companies.

The insight that emerged from those calls was precise: payroll was considered a burden, not a service. Business owners had to track down an accountant, navigate dense software built for accountants, and still worry they'd filed something wrong. The emotional register was stress, not confidence.

Gusto's answer was what Tomer calls "full service payroll" - a system where the software handles both the employee payment and all the tax filings automatically. No separate tax step. No accountant required. The user just hits run, and payday happens.

But the product decision that separated Gusto most clearly from everything before it was aesthetic. They added a payday celebration. When an employee gets paid, Gusto marks the moment - a small animation, an acknowledgment that something real happened. It sounds trivial. In a category defined by spreadsheets and dread, it was subversive.

The Accountant Alliance

One of Gusto's less-obvious strategic moves was building accountants into the platform rather than around them. Where payroll software historically treated accountants as users (or ignored them), Gusto gave accountants a dedicated portal that made their clients easier to manage - and made recommending Gusto part of their value-add. It turned a potential competitor channel into a distribution channel.

They also made a deliberate geographic choice early. Rather than targeting tech startups - the easiest early customer for any YC company - they went after the much harder market: traditional small businesses. Restaurants, dry cleaners, local service providers. Investors pushed back. Tomer held the line, because his father's store was the mental model, not someone's Series A SaaS company.

Every Friday, from Gusto's first weeks to today, Tomer sits down with his co-founders for a one-on-one. The purpose is simple: feedback. Not company updates, not metrics review - direct feedback on what each person could be doing better. He instituted this ritual in the very beginning, when it would have been easy to skip, and that decision normalized difficult conversations long before the company was big enough to need formal processes.

His hiring philosophy carries the same logic. He doesn't hire "toxic geniuses." He hired for humility first - people who describe their own weaknesses accurately, who view their current selves as works-in-progress. He puts it bluntly: "If you're self-critical in a constructive way with a growth mindset, always learning - that's what we hire for."

The counterintuitive thread in Tomer's leadership style is his comfort with long timelines. It comes directly from watching his father run the same store for four decades. Where most Silicon Valley operators talk in quarters, Tomer thinks in decades. He's building something he expects to matter for a long time - not just to exit, but to make his father, a small business owner, proud of what small businesses got from it.
