Founder-led · Valley built · Area code 607

Build the future in the Southern Tier

This valley invented the time clock, the flight simulator, and half of IBM. BUILD607 is a community of the people building what comes next here — founders, operators, makers, and the ones who never left.

The Valley of Opportunity

The roots run deep

They called this place the Valley of Opportunity — and they meant it literally. When the Chenango Canal tied Binghamton into the Erie system, a farm valley turned into a manufacturing corridor, and for the better part of a century the Triple Cities made things the whole world used.

Shoes. Cigars. Punch clocks. Computers. Flight simulators. Companies here didn't just employ people — they built the parks, the theaters, the neighborhoods, and the carousels their workers' kids grew up on. That's not nostalgia. That's a track record.

Then the big employers shrank, and a lot of the story since has been written by people who left. BUILD607 is for the ones who stayed, the ones who came back, and the ones building here on purpose. The infrastructure is still here. The university is here. The cost of building is a fraction of what it is on the coasts. What's been missing is a room where the builders can find each other.

The valley never lost the ability to make things. It lost the habit of making them together.Why BUILD607 exists
What this valley shipped
1830s
The Chenango Canal
Ninety-seven miles of locks connect Binghamton to the Erie Canal and open the valley to industry.
1889
Bundy Manufacturing
The Bundy brothers commercialize the employee time recorder in Binghamton — a machine that changed how the world counted work.
1899
Endicott-Johnson
Henry B. Endicott and George F. Johnson build a shoe empire and the Square Deal — housing, healthcare, and parks for workers — and two towns take their names.
1900
International Time Recording
Bundy and ITR become two of the four companies that merge into CTR — later renamed IBM. Endicott stays IBM's home plant for decades.
1929
The Link Trainer
Ed Link, working out of his family's organ factory, builds the first practical flight simulator. Every pilot trained on a simulator since traces back to Binghamton.
1959
The Twilight Zone
Rod Serling, raised in Binghamton, writes the valley into American television — and kept writing it in, episode after episode.
2017
The Koffman Incubator
Binghamton University opens a downtown incubator. Since then: 65 member companies, hundreds of jobs, and a clean-energy cluster taking shape.
2026
BUILD607
The builders in this valley get a room of their own. You're early. That's the point.
What we're building

A community, not a mailing list

Six things we're committing to in year one. Everything else gets decided by the people who show up.

Monthly

Builder nights

One night a month, one room, in Binghamton. Founders, engineers, makers, and operators — talking about what they're actually working on, not what they're pretending to work on.

Always on

The group chat

The unglamorous, useful part: a place to ask who does good fabrication work, who's hiring, who's raising, who knows a lawyer that answers the phone.

Quarterly

Long tables

Small dinners that mix people who are starting things with people who've already built something here. No pitch deck, no name tags, no panel.

Ongoing

The valley directory

A public map of who is building what across the 607 — startups, shops, studios, labs, nonprofits. If you can't see the ecosystem, you can't join it.

On demand

Warm intros

To the incubator, the university, the funds, the manufacturers, the city. Small places run on relationships. We'll make ours available.

Loudly

Telling the story

The Southern Tier gets written about in the past tense too often. We'd rather document what's being built right now, in public, with names and numbers.

Who it's for

If any of these is you, you're in

  • You're building a company in the 607 — any stage, any industry, revenue or pre-revenue.
  • You run something here that works: a shop, a firm, a practice, a farm, a nonprofit.
  • You're an engineer, designer, or operator who wants to build here instead of leaving.
  • You're at Binghamton University or SUNY Broome and you're not waiting until graduation.
  • You grew up here, left, and have been quietly wondering whether you could come back.
  • You invest in, mentor, or otherwise put your weight behind people who build in this region.
Who it isn't for

Two things we're not

  • A networking group where the product is the membership. Nobody is selling anything to the room.
  • A nostalgia society. We're proud of what this valley built. We're more interested in what it builds next.

There's no fee to join, no application committee, and no gatekeeping. Sign up, show up, and bring someone with you.

Join us

Get in the room

Tell us who you are and what you're building. We'll add you to the list, send you the next builder night, and connect you with people working on adjacent things.

We email a few times a month at most. No spam, no selling your address, unsubscribe whenever.

By signing up you're on the BUILD607 list. That's it — no dues, no obligation.

Questions

Answered plainly

What exactly is BUILD607?
A grassroots community for people building things in New York's Southern Tier. Monthly gatherings, a running group chat, a public directory of who's building what, and introductions between people who should know each other. It's run by the people in it.
Do I have to be a startup founder?
No. Founders are the core, but the room is better with engineers, designers, shop owners, students, researchers, and people who invest in this region. If you make things happen here, you belong.
Does it cost anything?
No. Signing up is free and there are no dues. If we ever run something with real costs behind it — a dinner, a venue — we'll say so up front.
Where does it meet?
Around Greater Binghamton, moving between downtown venues and host companies. We'll email the location with each event so it's easy to find.
I'm in Ithaca / Elmira / Owego. Am I in the 607?
Yes. The area code is the shorthand, not a fence. If you can drive to Binghamton for an evening, you're close enough.
I left the area years ago. Is this for me?
Especially. A lot of what this valley needs is people who know it, left, learned something elsewhere, and are open to bringing it back. Sign up and tell us where you are.
How can I help right now?
Three things: sign up, forward this to one person who should be in the room, and tell us if you can host an evening. Email us below.
