In this episode of the Partnership Mastermind Podcast, Chris Lavoie sits down with Hami Nasari from Aircall and Russell Bradley-Cook from HubSpot to break down one of the strongest co-selling partnerships in SaaS. Aircall and HubSpot have won Co-Sell Partner of the Year three years in a row, and this conversation gets into what actually makes a co-selling motion work beyond the usual “strategic alignment” talk. Hami and Russell share the real operating system behind successful co-selling: product usage, sales alignment, partner trust, customer value, integration adoption, internal enablement, and the hard work required to turn a partner relationship into a repeatable GTM motion. This is not a vague conversation about ecosystem theory. It is a practical breakdown of how two leading SaaS companies built a co-selling motion that drives real revenue, real product adoption, and real customer outcomes.
