The best way to build a company, counterintuitively, isn’t to build a company—it’s to build a product.
That’s the core insight from Marc Andreessen, the legendary entrepreneur and venture capitalist who co-founded Netscape and now runs Andreessen Horowitz, one of Silicon Valley’s most influential VC firms. In a fascinating observation about startup success patterns, Andreessen argues that many of tech’s most enduring franchises emerged not from deliberate company-building exercises, but from organic product development that only later crystallized into businesses. It’s a provocative thesis that challenges conventional startup wisdom and offers a clear lens for evaluating early-stage opportunities.
“There are products that become companies and then there are companies that come up with a product,” Andreessen explains. “One of the interesting things you see over the years is that many of the most successful technology franchises were products first, way before they ever became companies.”
He draws on his own experience to illustrate the pattern: “Netscape was a research project, was based on a research project at University of Illinois that we had worked on for three years prior. In fact, the team had come together at Illinois before we started Netscape.” The browser that would help define the early web wasn’t conceived as a business opportunity—it emerged from years of technical work and collaboration.
The examples multiply across tech history. “Microsoft—Bill Gates and Paul Allen were deep into PCs early on before they even thought there was a software business. Apple—Jobs and Wozniak built the first Apple sort of as hobbyists.” These origin stories share a common thread: the founders were solving problems or exploring possibilities that genuinely interested them, without a clear business model in sight.
More recent examples follow the same blueprint. “Mark Zuckerberg had Facebook running out of his dorm room way before he ever thought of starting a company,” Andreessen notes. Then there’s Twitter, which he calls a “favorite example.” “Twitter was a side project at a company called Odeo. Odeo wasn’t working. Twitter was a couple of guys who basically knew that the Odeo product, which was the podcasting product, was going to fail. So they were frustrated and unhappy and they started this side project, Twitter, and it just started to take off.”
Why does this pattern matter? Andreessen offers a compelling theory: “The product that becomes a company is a really good template because it’s a demonstration that the product has to exist. The market needs the product so badly that somebody actually built it and deployed it, and you can actually see evidence that people want it even before there was an economic motivation to do so. That’s market demand—something magical is going on there at that point.”
The inverse scenario—starting with the intent to build a company—carries significant risks. “We see a lot of failure cases, which is smart entrepreneurs sitting around saying, ‘I really want to start a company and now let’s go try to figure out something interesting and good to do,'” Andreessen observes. “It’s very easy in that process to kind of fool yourself into believing that there’s a market and that there’s a need, because you want to find something. You have a very strong motivation, internal motivation to come out with an answer. It’s very hard to go through that process for three months and then say, ‘You know what? We can’t come up with any good ideas. Let’s just go back to our day jobs.'”
His conclusion is unambiguous: “It has to be a really good idea that often will be an idea that is preexisting at the time you decide to start a company. And if it isn’t, be really careful because you’re walking on sharp rocks at that point with a high risk of falling off the cliff into the ocean.”
The implications of Andreessen’s thesis extend beyond individual startup decisions to broader questions about innovation and market validation. In today’s startup ecosystem, where founder ambition often precedes product clarity, his framework suggests a filtering mechanism: genuine market needs tend to generate solutions organically, while manufactured opportunities require constant artificial support. This aligns with the growing emphasis on “founder-market fit” and the success of companies like Stripe, which emerged from the Collison brothers’ frustration with payment processing while building other projects, or Figma, which grew from Dylan Field’s years-long obsession with collaborative design tools.
The pattern also challenges the “move fast and pivot” mentality that dominated startup culture in the 2010s. Rather than treating product ideas as interchangeable hypotheses to be rapidly tested and discarded, Andreessen’s perspective suggests that the best opportunities come from deeper engagement—months or years spent understanding a problem space before formal company formation. This may explain why enterprise software companies founded by former industry practitioners, or developer tools built by engineers scratching their own itch, tend to achieve stronger product-market fit than ventures founded on market research alone.
For investors and founders alike, the lesson is clear: the most promising startups often don’t look like startups at all in their earliest stages. They look like side projects, research experiments, and tools built for personal use that happen to solve problems others share. The company formation is almost an afterthought—a necessary structure to scale something that already works, rather than a prerequisite for discovering what might work.
