About Triangle Startups
What counts as a Triangle startup?
Triangle Startups is a front door to learning about the companies being built across Raleigh, Durham, Chapel Hill, and Research Triangle Park, and finding a way to participate.
The definition
What is a Triangle startup?
The test is about the company, its roots, and what it is building. It is not a test of whether an investor has approved it.
A Triangle startup is:
- A company, not a fund, accelerator, university, or support program.
- Independent and active, with a team still operating the business.
- Meaningfully rooted here, with a headquarters or substantive operating team in Raleigh, Durham, Chapel Hill, RTP, or the four core counties of Wake, Durham, Orange, and Chatham. A local customer, investor, or remote employee alone does not qualify.
- Building something repeatable, such as a product, technology, or scientific platform that can grow beyond the founders' own labor.
- Funded or not. Bootstrapped companies and university spinouts qualify. Venture funding is not a requirement.
- Building something repeatable, such as a product, technology, or scientific platform that can grow beyond the founders' own labor.

Boundary notes: contiguous Wake County communities count as part of the Triangle. Research-anchored companies just outside the four counties can qualify case by case when a Duke, NC State, UNC, or RTP through-line is clear. Editorial coverage may follow a broader Triangle story without adding a company to the active directory.
The purpose
What the site is for
Start here to learn who is building, what has changed, and where to take part. The relationships grow in person, through the teams, events, and conversations that make this place work.
02
Find a way in
See who is hiring and where builders are gathering. Use that context to show up, meet people, and continue the conversation in person.
03
Improve the record
Send a missing company, a source, or a correction. A useful public record should get better when people close to the work contribute.
The readers

Local institutions and public stewards
Use the record to see what is being built, correct gaps, and support participation without turning coverage into deal flow.
Investor boundary. The record is public, so investors can use it. The site is not an investor product. Deal flow and investor needs do not set the agenda.
Using the record
Citing our coverage
Every company deep dive and every signal log edition carries a named author, a publication date, and a permanent address, and can be cited from the block at the end of the piece. Coverage is not for sale and cannot be requested, arranged, or timed by the people it covers; companies and founders appear because of what the public record shows. If a piece is wrong, the correction is published on the same page.
Behind the record
Who runs Triangle Startups?
Triangle Startups is built and operated by Adam Schifferdecker from Chapel Hill, North Carolina.
How the record is builtClassification guide
What belongs where
The region includes many organizations that matter to startups. That does not make every organization a startup.
Swipe to compare all three columns.
| Organization | Where it belongs | How it is handled |
|---|---|---|
| Active product, science, or technology company | Startup directory | Included when it is independent, active, headquartered here or operating a substantive local team, and building something repeatable beyond the founders' own labor. |
| Acquired, closed, or relocated company | Historical record | Kept as part of the Triangle's company history, with its current status made clear rather than silently removed. |
| Fund, accelerator, university, or program | Supporting context | Covered when it helps explain the companies and the work. It is not classified as a startup. |
| Agency, consultancy, or local service business | Outside the startup directory | Not classified as a startup when the business primarily sells the team's time, even when the work is excellent or technology-enabled. |
