In this episode of the Scale Like a CEO podcast, Jonathan Brun, founder and CEO of Mnemonic, shares his journey of building a long‑lasting, bootstrapped B2B SaaS company that helps medium‑to‑large enterprises stay compliant with thousands of industry standards and regulations. He explains Mnemonic’s vertically integrated model that combines a massive library of standards with workflow software, positioning the product as an “Amazon for compliance.” Brun discusses the evolution of his hiring strategy—from early, multi‑hat, low‑salary hires to later senior talent with 20‑year experience—highlighting the importance of intelligence, integrity, and initiative. He describes the challenges of moving from a chaotic, creative start‑up phase to a more disciplined operation, drawing on lean manufacturing principles and the need for constantly updated policies. Brun outlines his acquisition playbook, emphasizing cultural similarity and product compatibility as non‑negotiable criteria for successful roll‑ups, and notes that Mnemonic has completed five acquisitions that have reinforced both talent and product breadth. Looking ahead, Brun reiterates his commitment to building an enduring, customer‑focused business that avoids exit‑oriented financing, aiming for sustainable growth, a stable work environment, and relevance over decades. He closes by inviting listeners to connect via LinkedIn.
