ABOUT US

We invest alongside you, not from the sidelines.

Operators, Not Advisors

We’re not former founders turned full-time investors. We’re building our own companies right now, alongside you. That’s the only kind of help that matters at this stage.

Community Over Capital

We don’t believe a wire transfer is value-add. Our founders build next to us in person, with office space, programming, and a room full of people who understand the fight you’re in.

Distribution Built In

Most pre-seed founders launch into silence. Ours don’t. We put millions of followers, a marquee conference, and real GTM muscle behind every company in our portfolio.

THE BULL CASE

The Triangle is the most underpriced startup ecosystem in the country.

Three world-class research universities.

Lower burn rates. Deepening talent density.

And sector advantages in fintech, healthtech, defense, and energy that coastal funds can’t replicate. The founders are here.

HOW WE SUPPORT

Capital, community, and go-to-market muscle for post-product startups.

Angel Checks & SPVs

We write $5K angel checks and lead deal-by-deal SPVs up to $100K. We’re often the first check in, but never the first bet.

We invest after the product exists and in founders with a seller and a coder on their founding team.

Founder Community

Portfolio founders work alongside us in person in Durham.

Founder dinners, GTM workshops, pitch practice, investor office hours, everything designed around what early-stage founders actually need: customers, capital, and clarity.

Amplification

Asset Management

Launch announcements, founder spotlights, product storytelling across millions of followers and owned media.

Plus AI Marketing World , our annual conference that gives portfolio companies a stage and our ecosystem a magnet for operators, investors, and buyers.

WHAT WE BELIEVE

Our philosophy on building companies.

Ship

The product has to exist. We don’t fund pitch decks or “what ifs.”

We invest after a founder has built something real, a working product with early users or contracts that prove the problem is real.

Show Up

In person. In our startup office space in Durham. Core founding teams build in the same room.

We’ve never seen a Slack channel replace the energy of founders building shoulder-to-shoulder.

Sell

Distribution is a founder’s job from day one. We back founders who treat go-to-market as a core competency, not something they’ll hire for later.

Build in public. Sell before you’re “ready.”
