Mike Salguero on the Fenway Hustle Behind ButcherBox

MS

Mike Salguero

Founder & CEO, ButcherBox

Mike Salguero raised serious venture capital for CustomMade, watched it come apart, and then started over. ButcherBox was built on a different operating system entirely — real customers, capital discipline, and a refusal to follow the default startup script. He gets into founder scars, second acts, why he skipped traditional VC the second time around, and what founders consistently misunderstand about growth.

Why Boston Wins Where Software Meets the Physical World with Natan Linder

NL

Natan Linder

Co-Founder & CEO, Tulip · Co-Founder, Formlabs

Natan Linder has built two of the companies that define Boston's edge where software meets the physical world — co-founding Formlabs and helping create the desktop 3D printing category, then founding Tulip to bring AI and modern software to the factory floor. He argues Boston should stop trying to copy Silicon Valley, and that the next generation of world-changing companies will come out of manufacturing, robotics, and life sciences instead.

From Family Business to Vertical AI Breakout with Benj Cohen

BC

Benj Cohen

Founder & CEO, Proton.ai

Benj Cohen didn't set out to build a venture-backed AI company — he set out to solve a problem he watched his family's distribution business struggle with for years. The Proton.ai founder and CEO explains how a Harvard applied math student turned a family business insight into one of Boston's breakout vertical AI companies, and why the city's deep bench of enterprise customers and technical talent makes it the perfect place to build B2B AI.

The Future of Bits + Atoms Gets Built in MA with Eric Paley

EP

Eric Paley

Managing Partner, Founder Collective

Eric Paley isn't here to reminisce about Route 128's glory days — he's here to bury them. The Founder Collective managing partner delivers a sharp thesis on why Massachusetts needs to stop looking in the rearview mirror and start chasing venture-scale outcomes in AI, "bits + atoms" companies, and the industries only Boston can build. A conversation about what it actually takes to turn world-class research into world-class companies.

Why Jason Kelly of Ginkgo Bioworks Is Still Betting on Boston

JK

Jason Kelly

Founder & CEO, Ginkgo Bioworks

The man who built a $4B biotech empire in Boston doesn't hold back. Jason Kelly drops a bombshell thesis: Boston has the real tech — biotech, robotics, atoms over bits — but is leaving generational wealth on the table by thinking too small. His fix? Ban human-driven cars downtown, turn the city into an autonomous vehicle playground, and for the love of God, stop trying to raise money in Boston. The wake-up call Boston's startup scene didn't know it needed.

Still Building. A Conversation with David Chang

David Chang

Founder, Via AI · Prev. Gradifi (acq. E*Trade), Where (acq. PayPal)

Serial acqui-hirer. Two exits to PayPal and E*Trade. David Chang has seen every cycle Boston has to offer — and he's not sugarcoating what went wrong. His diagnosis: the city's VC ecosystem caught a case of "beer goggle" skepticism — investors who'd shake hands over coffee in SF suddenly go cold when the deal lands back in Boston. But here's the twist: Chang argues local founders aren't lacking ambition, they're just doing the math differently. The episode that proves Boston's founder community runs deeper than any hype cycle — because "you're never going to enjoy building anything if you don't like the people."

PILOT Episode 1

What in the Boston Are We Doing Here?

Nick Leonard & Nathan Spielberg

Hosts, BUILD617

The one that started it all. Nick and Nathan rip the band-aid off Boston's tech scene with a single, uncomfortable question: why does this city have world-class talent, world-class capital, and a second-class startup culture? Nathan delivers the episode's defining hot take — Boston doesn't have a talent problem or a money problem, it has a hype problem. The city's allergic to its own cheerleaders. While Silicon Valley compounds success through relentless mutual celebration, Boston fragments into disconnected silos of universities, VCs, and banks that never overlap. This is the manifesto episode — the reason BUILD617 exists.
