Key Accomplishments

I've been a serial entrepreneur for 15 years. I've been in the first 10 employees at companies that went IPO, that sold for good exits, that sold for mediocre exits, that had small busts, and big busts! I still code every day, but am equally comfortable in 5-hour meetings, hashing out product, or slogging through the fundraising process. I'm particularly passionate about operations, how to run a product, technology, and company efficiently. I love bridging the gap between technical and business stakeholders. I'd love to partner with an exec who needs a great CTO founder. Or be a business co-founder with a highly-technical leader who is ready to monetize interesting technology, development tools, or cloud services.

Andrew Lau

Will brings diverse prospective to the table and is an all around good guy.
Jackson Deane

Aaron White

Mina Hsiang
They're my friends

Hadley Harris
We worked together at Thumb
Will is one of those rare folks in tech who is a brilliant CTO with the soft skills to manage and mentor others.
Nick Marden
We worked together  •  Founder, Rapid River Software. Two decades as lead Engineer at startups ranging in size from 1-1000, and in outcome from implosion to IPO
I've worked with Will in several capacities: as a colleague at Akamai, as a Cofounder of an Uber-ten-years-before-its-time service called Jo ... hnnyCab, and in various informal settings over the years. Will is absolutely brilliant. He focuses on the bigger picture, but has ample chops to dive into any (new or mature) technology to get the job done. I look to him as a thought leader on new technology trends and opportunities, because he truly does see things happening before other mortals like myself.
They're my friends
I've know Will for a decade. He's super-smart, communicative, and a brilliant entrepreneur.
Manuj Aggarwal
Chief Technology Officer, bazinga! Technologies and Principal Consultant, Spider Communications Inc..
He is a software and intellectual power house. Will have been involved in and responsible for very widely known startups.

Nick Marden
We worked together at Akamai Technologies, Inc.
I've known Nick in a few capacities, including being a former co-founder with him. He is painfully smart. He is a true software craftsman, ... without letting the craft interfere with a pragmatic approach to using technology as a tool to serve business needs. For numerous companies he has been a "white knight", swooping in to clean up wide-ranging technology and product issues. He's created tens of millions of dollars in enterprise values for those companies, and he's more than ready to jump into doing it again for his own business with a great founding team. Nick is a technology mentor, a natural engineering leader without being an overbearing "manager type", which earns him the respect of his often-younger geek peers. He's one of the unicorns of tech founders, and an ideal candidate for Founder Dating.
