The Next Great Seed Fund Is Getting Built Right Now — Just Not in Silicon Valley
When I first launched Symphonic Capital, I was still in the Bay Area, and I watched the scale story begin in real time. The expectation baked into every conversation was that exit outcomes were only getting bigger. The kind of fund I actually wanted to build — focused, disciplined, close to the founder, where success doesn't hinge on multi-billion dollar exits but can actually be built around $500M+ outcomes that would be a win-win for everyone — was already going out of style before my first close.
At the time, I couldn't tell if I was watching a blip or a permanent shift. Almost five years in, I think we can call it: permanent. But it's not that Silicon Valley got so successful its own model stopped working there. It's that it got bored of the old game, because it realized there was a bigger one to play. That's the thing about Silicon Valley: more is always more.
But what happens when you actually have a clear vision of what getting so big costs society and that cost is too high for you to pay? When you aren't enticed by a SpaceX IPO because you know the shortcuts that a company must take to grow into a trillion dollar outcome? When you have a clear picture of what "enough" means to you, and you're building a company not just for the wealth you know it will create for you and your family, but for the impact it will have on the people it's built for, you are building something incredibly powerful.
We've been running this playbook for the past five years, and I've become increasingly convinced that the market has caught up to us. Let's get into why.
Timing is everything: the old guard has moved onto a different game
For a decade, if you wanted to build a venture firm around real founder access, concentrated conviction, and a disciplined path to returns — the model Sequoia and Kleiner Perkins built their names on — you were competing with Silicon Valley for the right to play it. That competition is over. Silicon Valley's own winners have moved on to a different game, one only a handful of the world's largest funds can afford to play.
A recent Wall Street Journal profile of the investors cashing in on the SpaceX, Anthropic, and OpenAI wave made the shift concrete for me. Spark Capital led Anthropic's Series C with a $75 million check in early 2023, the largest check the firm had ever written; that stake is now worth roughly $7 billion. Greenoaks co-led the round that valued Anthropic at $965 billion just a few months later — a jump in scale, inside the same company, in under three years.
This escalation happened because they had already played the old game, and the reward for playing that game well meant growth. So they did. They grew their own firms: larger teams, bigger offices, fancier annual general meetings, and the next hurdle was to raise a $1 billion-plus fund. That escalation changed the rules.A $500 million fund and a $5 billion fund aren't playing the same sport anymore, even if they're both called venture capital. Every dollar Silicon Valley moved up-market is a dollar it stopped defending at the size where the rest of us actually operate — which is exactly the opening. The companies building what traditionally would have been successful in the Valley are overlooked now, and the founders behind them are disillusioned by, and don't want to, compete in the new game. To be clear, that doesn't mean these companies aren't building in AI, plenty of them are. It means they can get to a great outcome with a fraction of the capital, because they're not chasing the kind of scale that only makes sense if you're trying to justify a multi-billion dollar fund. That's fine by us. It just means the old game, capital-efficient, founder-close, built around outcomes that are big but not absurd, is sitting there, uncontested, for whoever's still willing to play it.
Silicon Valley exported its own playbook
Part of why this window exists isn't just marketing, though marketing is where it started. Marc Andreessen wrote that software was eating the world, and Paul Graham spent the better part of two decades as Silicon Valley's chief evangelist, essay after essay teaching anyone paying attention how to think like a founder.. But the evangelism was only the opening move. Underneath it, Silicon Valley spent two decades actually building the infrastructure, the apprenticeship pipelines, the fund-formation playbooks, the operating experience, that let people elsewhere act on what they'd been taught. The marketing worked, and it worked on two fronts at once: it taught the world how to invest, and it taught the world how to build. Both the lessons and the people who learned them, eventually left the Bay.
Take the capital side first. Angel investors in cities that never had a term sheet cross their desks now know exactly what a SAFE is, what a fund is for, what an outcome is supposed to look like and the dollars followed the education. A decade ago, the Bay Area alone was pulling in on $20 billion a year in venture capital, roughly the pace set in early 2014, before the AI-driven mega-round era reset the scale of what "big" means. Today, per Carta's data, New York alone drew $22.3 billion and Boston $10.8 billion in the twelve months through June 2026 — each operating at or above the scale the entire Bay Area commanded when the old playbook was dominant. San Diego, Austin, LA, and Denver/Boulder are all climbing that same curve.
The talent side moved on the same timeline, for the same reason. Silicon Valley spent 2010 through 2020 running an apprenticeship model at full tilt, and not just inside VC partnerships: people cut their teeth under Moritz at Sequoia and inside Thiel's Founders Fund, and just as many trained inside the companies themselves, as FAANG went from scrappy to institutional in that same decade. Amazon alone grew from roughly 33,700 employees in 2010 to nearly 1.3 million by 2020, and an entire generation of operators and engineers got their education inside that growth curve. Two more tracks fed the same pipeline: people who apprenticed inside someone else's fast-scaling startup as an early or second-time hire, and founders who ran the apprenticeship on themselves by launching their own first company in the Bay Area. All of them came away with a clear enough view of the machine to run it their own way, and a meaningful share have already left the Bay physically, the way Nosek relocated when he left Founders Fund to build Gigafund.
So the same evangelism that convinced the rest of the country it was safe to write a check also trained the people who'd go on to build and back the next round of companies somewhere else. Silicon Valley taught the rest of the world its own playbook, then watched both halves of it, the capital and the people who knew how to deploy it, walk out the door. What kept them from competing with the Bay sooner wasn't a lack of readiness; it was that Silicon Valley's capital was still occupied defending the same early-stage lane those operators were built to play in.
We're not just theorizing — we're building it
Shruti and I have watched this play out directly in our own portfolio at Symphonic Capital, and in our own lives building the firm together. That's what we saw in founder prototypes like Alex Wright-Gladstein, who is a founder in the Symphonic Capital portfolio. Her first company, Ayar Labs, was built in the Bay Area — deep-tech silicon photonics spun out of MIT research, the kind of capital-intensive bet the old apprenticeship model was built to fund. That was her training ground. Her second company, Sphere, which helps make retirement portfolios fossil-fuel-free, she built from San Diego, once she no longer needed Silicon Valley's ecosystem to do it.
Shruti and I lived the same story, from the investor's seat instead of the founder's. She co-founded Move Loot in San Francisco, a YC W’14 backed used furniture marketplace that scaled across the country and raised $22 million from many of the Bay Area's storied investors — the full Bay Area playbook, built and run inside it. I did my own apprenticeship in early-stage investing there too, at one of the first pre-seed funds in San Francisco. We each left once the cracks in that old model became impossible to unsee in the early 2020s: check sizes ballooning, timelines stretching, the model quietly re-optimizing for a scale neither of us wanted to chase. Shruti relocated to North Carolina in 2021, and I moved to San Diego that same year.
That we ended up building Symphonic together, as a firm split across two ecosystems and neither of them the Bay Area, is itself part of my point. Our thesis was never that Silicon Valley talent should move to San Diego specifically — it's that talent trained in the old model can run that model anywhere.
There isn't another fund running this playbook that's been on both sides of it the way we have. Shruti apprenticed inside a startup, building and scaling her own company . I apprenticed inside a fund, learning how to build one. Between the two of us, we know what it actually looks like to be the founder living the old playbook and what it looks like to be the investor guiding one through it — which means we can both spot the talent ready to run it and actually support them once they're in it, whether that talent is still in Silicon Valley or has already left. Plenty of funds can write the check. Far fewer can recognize the founder before the rest of the market does and then do the hands-on work the old playbook actually requires.
There's a new clearing available right now for the next great seed fund, one that takes the learnings of the last two decades and brings them to where the talent actually lives. The old math still works, it just requires founders committed to building inside that playbook, and investors hands-on and experienced enough to guide them through it. Silicon Valley used to be the only place both existed in the same room. Now they exist in San Diego, Durham, Austin, and Denver, and Symphonic is the blueprint for the fund that shows up to match them.
