Step Function invests at the earliest stages in technical founders building the next generation of category-defining infrastructure software companies.
We believe
Incremental improvements at the infrastructure layer allow for step function changes in end-user experience at the application layer.
Your earliest investors should act as a step function change on the trajectory of your business.
Investments
We back founders building iconic companies in developer tools, data infrastructure, AI infrastructure, security, monitoring & observability, and other areas of enterprise infrastructure.
Team
William Lehmann, Founder & General Partner
I’ve spent my entire career investing in technical founders at the earliest stages.
Before starting Step Function, Will was a Partner at Bain Capital Ventures (BCV), where he spent a decade investing in early-stage enterprise software companies.
How we deliver Step Function value

“Expect a clear-cut impact from day 1. Step Function stands out for hands-on and tangible mentoring and access to potential customers via a well-connected network. Every intro we got from Will turned into business value.”

“Will has immediately become a trusted advisor. A voice I choose to turn to first because I respect the quality of the advice and insight. He collaborated on investment narrative, fundraising prep and tactics, and provided high value introductions”
“Step Function is an early fund, but Will is the best investor you can have on your cap table. He was clear about his commitment to support us as founders. That made him stand out, and he has delivered on those statements ever since.”
