The best founders. Found first.

There’s something painfully American about the arc of iRobot, the company that taught your vacuum to navigate around the furniture. Founded in 1990 in Bedford, Massachusetts by MIT roboticist Rodney Brooks and his former students Colin Angle and Helen Greiner, the company filed for Chapter 11 bankruptcy on Sunday, punctuating a 35-year run that took it from the dreams of AI researchers to your kitchen floor and, finally, to the tender mercies of its Chinese supplier.

Brooks, the founding director of MIT’s Computer Science and Artificial Intelligence Lab and the robotics field’s resident provocateur, spent the eighties watching insects and having epiphanies about how simple systems could produce complex behaviors. By 1990, he’d translated those insights into a company that would eventually sell over 50 million robots. The Roomba, launched in 2002, became the rare gadget that transcended its category to become a verb, a meme, and, to the amusement of many, a cat-transportation device.

The money soon followed, with the company raising $38 million altogether, including from The Carlyle Group, before going public in a 2005 IPO that raised $103.2 million. By 2015, iRobot was flush enough to launch its own venture arm, prompting TechCrunch to wryly declare that “robot domination may have just taken another step forward.” The plan at the time was to invest $100,000 to $2 million in up to 10 seed and Series A robotics startups each year. It was the kind of move that marks a company’s arrival, the moment when you’re successful enough to fund the next generation’s dreams.

Then Amazon came knocking. In 2022, the corporate giant agreed to acquire iRobot for $1.7 billion in what would have been Amazon’s fourth-largest acquisition ever at the time. In a press release announcing the tie-up, Angle, who’d been CEO since the company’s inception, spoke about “creating innovative, practical products” and finding “a better place for our team to continue our mission.” It seemed like a fairy tale ending — the scrappy MIT spinoff absorbed into the Everything Store’s sprawling empire.

Except European regulators had other ideas. Indeed, amid threats they would block the deal — they believed Amazon could foreclose rivals by restricting or degrading access to its marketplace — Amazon and iRobot agreed to kill the deal in January 2024, with Amazon paying a $94 million breakup fee and walking away. Angle resigned. The company’s shares nosedived. It shed 31% of its workforce.
