What is the perfect creative environment?
Early conviction. Long-term commitment.
We invest from inception through seed—from the first spark of an idea through initial traction and early company-building. First checks of $250K to $1.5M. We prefer to lead or co-lead. And as generalists, we don’t fit founders into a box.
People first
Market and traction matter, but we focus on founders. Big visions, a bias toward action, and the ability to execute. We like to meet founding teams early and build relationships well before a fundraise.
Southeast native
We invest in startups building in Atlanta and across the Southeast. We know this ecosystem because we helped build it. We bring local depth that distant funds can't match.
All in
Capital is only part of our commitment. Our Operating Partner network, our community of founders and advisors, our active personal engagement. When we invest, we help you build an unfair advantage.
Our People
We’ve stood where you stand. We’ve built companies, raised capital, navigated acquisitions, and learned from every stumble along the way. We bring all of that to every founder we back.

Sean O’Brien
Co-founder & Managing Partner
Sean has spent 28 years in investment banking, hedge fund management, and corporate strategy. As President and Chief Strategy Officer at PGi, he completed over 30 acquisitions and helped orchestrate the company’s exit to private equity. He is an active mentor at Techstars Atlanta and Endeavor Atlanta.

Michael Cohn
Co-founder & Managing Partner
Michael co-founded Cloud Sherpas in 2008 and held many roles—CEO, VP Product, and ultimately SVP Marketing—as the company grew to nearly $200M in revenue and 1,200 employees before its acquisition by Accenture in 2015. He launched Techstars Atlanta as its founding Managing Director in 2016. After years of angel investing and mentoring founders across the Southeast, Michael co-founded Overline with Sean in 2020.
Extended Team
Operating Partners
Our Operating Partners aren’t advisors in name only. They actively engage with our portfolio—joining founder calls, making introductions that move the needle, and bringing hard-won expertise that only comes from having done it themselves.
