In this Season 5 episode of Peter Lohmann’s property‑management podcast, host Peter Lohmann interviews Tollie Brown, a principal on the investment team at Mainsail Partners and board member at Rentvine. The conversation begins with Tollie’s background and Mainsail’s 22‑year history as a growth‑equity firm that backs bootstrapped B2B software. She explains why Mainsail chose to invest in Rentvine, tracing the firm’s earlier prop‑tech bets (Paylease, Nexus, ResMan) and the evolution from Property Manager Websites (PMW) to the Rentvine accounting platform. The discussion moves to the importance of a technical co‑founder paired with deep industry expertise, and how that dynamic accelerates product‑market fit. Tollie clarifies how growth equity differs from venture capital and traditional private‑equity, noting a typical 3‑5‑year horizon, flexible exit paths, and a focus on building sustainable businesses rather than financial engineering. The interview then explores the competitive advantages that Rentvine offers: strong trust built by founders Dave Borden and John Ewen, world‑class customer support, an open API ecosystem, and a product roadmap that balances in‑house development with best‑of‑breed integrations. Tollie describes Mainsail’s hands‑on partnership model—weekly catch‑ups, quarterly board meetings, a 30‑person growth team that provides advisory, project work, recruiting, and a peer network. She highlights recent hires (CFO, head of sales, head of marketing, customer‑success leader) and product pods that keep innovation moving. The conversation shifts to market dynamics: the large, durable, and growing rental housing sector, the distinction between single‑family and multifamily management, and the associated risks (fragmented single‑family market, higher unit volatility, competitive pressure). Trust and perceived support are identified as the primary drivers of software switching for property managers. AI’s emerging role is discussed, with Mainsail launching an AI Lab to help portfolio companies embed AI into accounting workflows and broader services. Finally, Tollie and Peter debate bundling versus unbundling of prop‑tech functionality, the evolution toward open integrations, and the future outlook for both Rentvine and Mainsail’s investment strategy.
