What if one of the oldest marketing channels became one of the smartest — measurable, automated, and fully connected to your digital stack? In this episode of the Scouting for Growth Podcast, Sabine VanderLinden speaks with Dennis Kelly, CEO and co-founder of Postalytics, to explore how product-led growth (PLG) and smart engineering are transforming direct mail from a legacy tactic into a modern growth engine. Dennis is a six-time entrepreneur who has built both VC-backed and self-financed businesses — exiting four of them to larger corporations. His story starts far from Silicon Valley. Growing up on a farm, he learned early the value of hard work, community, and knocking on doors to offer help. Those lessons still shape his leadership style today: build something useful, show people how it helps, and let the product do the talking. Postalytics reflects that philosophy. Direct mail has always worked — but it’s been painfully slow, opaque, and disconnected from modern marketing systems. Postalytics was built to fix exactly that. The platform automates direct mail campaigns in minutes instead of weeks, bringing digital marketing best practices — speed, personalisation, and measurement — into the physical world. The breakthrough is connection. Postalytics integrates directly with CRMs and marketing automation platforms like HubSpot and Salesforce, turning direct mail into a first-class digital channel. Every mail piece can include a unique, fully encrypted QR code, allowing marketers to track delivery, engagement, and website behaviour — just like email or paid media. Offline touchpoints finally generate online insight. Dennis also explains why PLG matters far beyond SaaS buzzwords. Product-led growth means reducing friction, letting customers experience value quickly, and scaling efficiently without massive capital outlays. Thanks to falling cloud infrastructure costs, Postalytics was able to build a high-performance, scalable platform without raising VC funding — and grow sustainably as revenue followed usage. This model is now powering Postalytics’ expansion across the US and Canada, with clear ambitions to move into Europe — proving that not every high-growth company needs venture capital to win.

Sometimes, it means taking what already works — and finally making it measurable, connected, and fit for the modern growth stack.
