We buy software businesses worth keeping.

Third South Capital acquires and operates profitable niche software businesses. We're operators, not flippers. We also deploy AI for operators who want to build it in-house.

Who We Are

We're four partners who, separately, got obsessed with the same idea: owning and running a portfolio of small software businesses. The name comes from where three of us met: the top floor of Yates dorm, third section south.

Harrison Roday — M&A and private equity. Years of middle-market deal execution and investment banking.
Colin Burns — public markets and capital allocation. Long/short public equity investing across US software and technology at global hedge funds.
Justin Duke — software engineering and SaaS. Engineer and engineering leader at scale; founded and runs a SaaS product used by thousands.
Myles Marino — Early-stage operations; leads M&A and portfolio operations.

Services

We deploy AI for operators outside our portfolio, the same tools we built for our own businesses. It starts with a workshop: we map your operation, identify what's worth pursuing, and give you an honest read. If we move to implementation, the deliverable is a working tool your team owns. No retainer. No dependency on us.

Where We're at Our Best

Founder wants out. Built something real, been running it for years, done. We move fast and don't waste time.
Messy situation. Wrong capital structure, technical challenges, and more. We're comfortable with complexity; it's often where we add the most.
Corporate divestiture. A parent company with software as a non-core asset that needs a buyer who will actually operate it, not flip it or let it decay.

Acquisition Criteria

We buy vertical and niche SaaS. 70%+ recurring revenue, teams under 10, 5+ years of operating history. We don't buy pre-revenue or growth-stage businesses, consumer software, single-customer concentration above 40%, platform-dependent software, or businesses that only work because the founder is still in it.

Current Portfolio

Blue Canary Software, Zendesk applications used by thousands of agents
Icon Horse, the easiest way for developers to retrieve icons for a given URL
Clipboard History Pro, a browser plugin for managing your clipboard history
EntryThingy, gallery and open-call management for arts organizations
