TIRTA

Co-founders Brett H. Barth and Larry G. Raffone share responsibility for the firm's investment decisions. Barth serves as CEO with a background that includes co-founding wealth management firm BBR Partners. Raffone, as Chairman, previously held senior leadership roles at Fidelity Investments. Both are active in deal sourcing, due diligence, and portfolio company governance.

TIRTA sources opportunities through the co-founders' combined professional networks, which span institutional allocators, venture capital managers, and operating executives in enterprise technology. The firm emphasizes pre-existing relationships with founder-led companies, often engaging well before a formal fundraising process begins. Portfolio company founders and existing co-investors also contribute to deal origination.

TIRTA focuses on growth-stage businesses that have reached $10 million to $50 million in annual revenue and demonstrated product-market fit. The firm does not participate in seed or early-stage venture rounds. Its capital is designed to accelerate scaling — expanding sales teams, entering new geographies, and developing adjacent product lines — rather than funding initial market entry.

TIRTA invests directly into portfolio companies and structures each transaction as a tailored equity commitment — common stock, convertible preferred, or a hybrid. Based on public filings and portfolio composition, there is no indication that the firm makes fund-of-fund commitments to outside managers. It operates as a direct-investment growth equity platform.

TIRTA does not publish a formal exclusion list, but its disclosed portfolio and stated strategy concentrate heavily on enterprise software, financial technology, and digital health. Hard-tech sectors — semiconductors, advanced materials, deep biotech — and capital-intensive industrial businesses are not represented in the firm's known investments and appear outside its thesis scope.
