Ken is what you might call a serial entrepreneur with pattern recognition. He has built and scaled multiple companies, but BluStream came from somewhere more personal than market research. It started with a guitar sitting on a wall, cracked beyond repair, and a simple question: why didn't someone tell me?
The gap between purchase and delight
Most companies invest heavily in getting customers to buy. They perfect their websites, refine their CRM campaigns, build slick e-commerce stores, and track packages right to the doorstep. Then the box arrives, and the relationship goes quiet. The next contact is usually a request for a review or a discount code for the next purchase, often before the customer has even opened the packaging.
Ken calls this the "doorstep to delight" gap. BluStream exists to fill that gap with product-focused messaging that educates, supports, and guides people through their ownership journey. Not promotional emails. Not support tickets. Just helpful, timely conversations that meet customers where they are.
When your product can't talk to you
Ken's story begins in a cold New England winter with a new acoustic guitar that cracked when the temperature dropped and the air got dry. The brand had all the information about humidity care on their website, but Ken never saw any of it. When he discovered his co-founder had the exact same experience, they started asking: what if companies could stay connected to customers around the product itself, not just around promotions?
Validating the problem before building anything
Before writing a single line of code, Ken and his co-founders talked to fifty, maybe a hundred businesses. One early test happened at NAMM, the national music trade show in Los Angeles. They stopped people with guitars on their backs and asked if they knew humidity could damage their instrument. Most players had no idea. Meanwhile, manufacturers on the show floor knew all about it. BluStream was built to be that missing connection.
The pivot from IoT to SaaS
When BluStream started ten years ago, the solution involved IoT sensors that could monitor humidity and temperature inside products. But IoT required selling hardware, managing inventory, and dealing with physical product complexity. Three years ago, Ken pivoted. BluStream would focus entirely on the dialogue-based product journey platform, and the IoT side would spin out as a separate partner business. Startup journeys are never straight lines, even with experience.
Retention through connection
BluStream clients see a 90% retention rate among customers who go through a product experience journey, plus a 30% reduction in churn. The platform creates dynamic, two-way dialogues that adapt based on customer feedback. Ken gives the example of hair supplements that take 30, 60, or 90 days to show results. Without guidance, customers assume it is not working and move on. With a product journey that sets expectations and checks in at the right moments, they stick with it long enough to see results.
Building teams around common goals
Ken doesn’t believe in rigid job descriptions, at BluStream, they use "job outlines" and plan in six-month cycles. Everyone understands where the company is headed, creating a culture where people help each other. This year, the whole team rallied around Journey Builder AI, a tool that instantly generates customer dialogues and workflows. Ken describes himself as the straw that stirs the drink, but the real power comes from making sure everyone knows the mission.
Advice for founders starting out
Ken's advice is straightforward, make sure the problem you are solving is big enough to support a business. Get out of the building and talk to at least 50 potential customers before you commit. Second, understand that it is never a straight line. Get something into customer hands early, even if imperfect. And if you are raising capital, choose investors carefully. It is a long-term relationship, not a transaction.
