About

Built from Chapel Hill by Adam Schifferdecker.

When I got here, I had no working map of who was building what. The information lived in LinkedIn posts, GrepBeat archives, founder DMs, Tweener Times, event notes, and company pages.

This is the record I wanted then: company profiles, founder records, funding rounds, source notes, and signal logs when something actually happens.

My background sits between operator and builder: marketplace operations, AI-native software, and the habit of turning messy conversations into source-backed records.

Operating manual

Records before claims

Company pages name what is known, what is missing, and where facts came from.

Corrections stay close

Founder and operator corrections belong next to the record they improve.

Trust cannot be bought

Partner placement and future paid surfaces have to preserve the basis for trust.

From LinkedIn

Today, information on startups in the Triangle is exclusive, scattered, and paywalled. Triangle Startups lets founders, operators, and the startup-curious research and connect with startups here. The platform includes a database you can query in natural language, an event calendar that pulls from 20+ sources, and editorial that covers what companies are building.

If you're a founder building in the Triangle, we should already have your company in the database. I'd love to make sure we got it right. If you're an operator or builder who's been watching this space, I'd love to hear what you think.
