I do growth for developer products. I also write the code.

Groupthink

Founder and CEO, and the entire engineering team

Relationship intelligence for people who run on meetings. I write, review, and ship all of it, alone, with AI agents.

• Took engineering throughput from 15 merged PRs in January 2026 to 707 in August. September passed that in three weeks. The record with a team of five was 287.
• Took all-in cost per merged pull request from $430 to $42 in August. Monthly burn fell from $104K to about $30K.
• Repositioned the company in March 2026 from a meeting notetaker, a category Google and Zoom commoditized, to a relationship intelligence platform.
• Run the whole company as markdown in git (strategy, decisions, runbooks) so an agent can read it.

Firstparty

Cofounder and CTO

Developer-first marketing analytics, built with Jonathan Kressaty.

• Funded within 48 hours of tweeting about the idea; raised a $5.7M seed in 2022.
• Owned engineering as CTO. We never found product/market fit and pivoted rather than coast; the pivot became Groupthink.

GitLab

GM of Meltano, then Senior Director of Growth Marketing

Ran an internal startup, then the growth team, reporting to the CEO for the first year.

• Ran Meltano as an internal startup, hired my own replacement, and it spun out with a $4.2M seed led by GV.
• Built the growth marketing team. Left shortly before the IPO.

Mattermark

Cofounder and CEO

The deal intelligence company, started with the $350K left in the previous startup's bank account.

• Union Square Ventures was the first paying customer. Revenue reached about $3M ARR and the team peaked at seventy.
• Wrote the Mattermark Daily to 100,000 readers, which was the top of the funnel for years.
• Sold to FullContact in December 2017. The sale did not clear preferences, so common stock, mine included, went to zero. I stayed six months at the acquirer to land the plane, and wrote about all of it.

Referly

Founder and CEO

Y Combinator, Summer 2012.

• Raised $1M and grew to ten people. The idea was wrong, so we killed it instead of running a zombie.

Twilio

First marketing hire, through Director

Joined when the company was working out of borrowed office space.

• Ran marketing to developers through Twilio's first 100,000 customers.
• Built the team from zero to eighteen people over three years, including the developer evangelists. Started the customer success team.
• Worked the hackathon circuit with the evangelists, TechCrunch Disrupt included, and spoke at developer events.
• Launched the Twilio Conference and the Twilio Fund.
• Hired Twilio's first international employee, a developer evangelist in London, and did evangelism across Europe myself.
• Launched Twilio SMS, and wrote the demo apps and screencasts that sold it.
• Forbes 30 Under 30.
