Buying Online Businesses Podcast 26 Saas Business Acquisitions & Growing with Saas M&A Professional Guillaume Lussato
What does it really take to acquire 26 SaaS businesses—and keep them growing?
In this episode, Jaryd Krause sits down with SaaS M&A professional Guillaume Lussato for a behind-the-scenes look at how successful software acquisitions actually happen. Guillaume breaks down his unconventional path from software sales at a cybersecurity company to sourcing and closing deals at Constellation Software, one of the most disciplined acquirers in the SaaS world.
Guillaume reveals why the best SaaS acquisitions aren’t rushed deals but relationships built over years. He shares how patience, credibility, and consistent founder outreach led to his first acquisition at SaaS Group—a low-profile digital calendar tool called DacBoard—and why targeting under-the-radar SaaS companies can unlock outsized opportunities.
The conversation dives deep into today’s hyper-competitive M&A environment, including how to stand out when every founder is being pitched. Guillaume unpacks the red flags most buyers miss, from risky customer concentration to weak net dollar retention, and explains SaaS Group’s clear acquisition framework—capital-efficient, product-led growth businesses with strong fundamentals.
The episode wraps with a powerful discussion on how to balance organic growth with acquisitions, avoid overextension, and make smarter strategic decisions when scaling a portfolio of software companies.
