This week, Gusto co-founder and CPO Tomer London shares how relentlessly cold-calling potential customers taught him to recognize what PMF really feels like.
Gusto’s Path to Product-Market Fit — How Listening to Customers Built a $9.6B Company [https://email2.firstround.com/c/eJxUj81q6zAQRp9G2jmMZvS70OLCxe8haTSNqB0XR0mhT18auuny-zhwOJxrNd7qnk3wMWEKhnTfy9iWwdknLzWBLRSJPAAYgtI46mtujRy7kCKiFbCUXOHoLAc2pQVhPTICejAIJqBx5gLiXCThGkSYOykLMs77PI_HjS_t2PWWr3N-3BX9U7gqXM_-HP3z8pf6-RWuvXQrGKOidVf0n6pAxAYLm-YXKzYuCUkWaSEkk4gDOH3mr3kqC9so-3F7KWd-ux73ubyS9cz1sb3_jmfG7wAAAP__SpZUlw]
It’s 2012 and Tomer London has locked himself in a closet, phone in hand, to dial the numbers of small business owners he finds on Yelp, taking rejection, after rejection, after rejection on the chin. He’s recently dropped out of an electrical engineering PhD program at Stanford to focus on the payroll startup he co-founded with Josh Reeves and Edward Kim that will eventually become Gusto.

They were concurrently exploring building an API payroll product for enterprise platforms. But all that cold-calling had revealed a surprising truth: Among prospective customers, SMBs were much more enthusiastic than ENTs.
“I remember going to some of these big platforms and we were sure they were going to love it. But the response we mostly got was, ‘This could be cool, but it’s not a priority right now.’”
SMBs, meanwhile, were clamoring for a product to solve their payroll problems …
