Aaron Foss is a serial entrepreneur who has built five companies, including Nomorobo, the service that has stopped billions of unwanted robocalls and spam texts. Nomorobo was acquired by Applause Group in August 2023. Before that, Aaron participated in Techstars NYC with SideTour, which Groupon acquired in 2013. He has testified before Congress three times and has been featured by outlets including The New York Times, Wired, CNN, CNBC, and Fox News.
In this conversation, Aaron explains how to identify problems worth solving, distinguish progress from real traction, and know when to narrow your focus from a wide flashlight into a laser. We also discuss why entrepreneurs should fall in love with the problem instead of chasing trends, how constraints can improve creativity, what he looks for in founders, and why his work with Defy Ventures has become such an important part of his life. Aaron also shares lessons from building and selling companies, along with the books and negotiation tools that helped him along the way.
