5 min readiRobot: Colin Angle — How the Roomba Became a Household Icon
Colin Angle was 22 when he agreed to run a robotics company that didn't yet have a product, a customer, or a business model. The year was 1990, and the company was iRobot, co-founded with MIT professor Rodney Brooks and fellow student Helen Greiner. For the first six and a half years, Angle started every month without enough money in the bank to make payroll. The company survived by selling research robots to corporations like Mitsubishi and Boeing for $5,000 to $10,000 apiece, collecting half the money upfront to buy parts. "We really lived hand to mouth," Angle says. "It was six and a half years before I started a month with enough money in the bank to make payroll."
Learning to Build a Business by Not Knowing How
iRobot began as a contract research shop, not a consumer company. Angle and his team were engineers building robots for NASA, the military, and industrial clients. They had no marketing or distribution capability. "You weren't allowed to say marketing without saying 'weenie' immediately afterwards," Angle recalls. The company's mission statement was: "Build cool stuff, deliver great product, have fun, make money."

Colin Angle didn’t start out trying to clean people’s floors.
He started out trying to shape the future–with robots.
In the early days of iRobot, there was no business model. No steady funding. No clear customer.
Just a belief that robotic technology would one day make the world a better place.
In the early days, the company built babbling toy dolls for Hasbro, and roving bomb-detectors for the military.
But for more than a decade… nothing truly took off.
Until one idea—a robot vacuum—finally did.
With the Roomba, iRobot created a category from scratch, and a product that felt almost like a member of the family. Tens of millions of units sold, and the Roomba became part of popular culture.
But to avoid stagnation, iRobot had to sell to a bigger company. When a lucrative deal with Amazon fell through, the company hit a wall–and never recovered.
This is a story about building a business in survival mode, creating a household icon, and eventually getting bested by forces beyond your control.
