Friends of Greentown,

How do you go from a 100-square-foot prototype space to powering 100,000 industrial processes worldwide? Ask Laminar. Since joining Greentown in 2021, this sibling-founded startup has scaled to serve six of the ten largest food and beverage brands globally.

By using AI-powered sensors to "see" inside factory pipes, Laminar has turned a massive waste problem into a competitive advantage, slashing chemical use by 40% and water consumption by up to 25%.

The company’s growth story is a masterclass in combining disciplines to solve a real industrial pain point, staying “customer-obsessed,” and scaling technology innovations from first prototype to widespread commercial deployment.
