DevRel built from
experience, not theory

Relate Crew is a Maryland-based fractional DevRel consultancy founded by Brendan O'Leary. We help developer-tool companies — primarily startups — who need DevRel expertise but aren't ready or able to hire a full-time team.

Founder background

GitLab — 5 years. Joined when the company had 150 people and left at 3,000. Started as an engineering manager for self-hosted infrastructure, then spent 3 years in DevRel under Priyanka Sharma, building the program from the ground up.

Kilo Code — from week 5. The most popular open source AI coding agent, co-founded by GitLab's Sid Sijbrandij. Joined as full-time DevRel and built the content engine and community from scratch, scaling to 2 blog posts per day. Beyond shipping an AI product, used AI natively across GTM, content production, and community operations — proving that AI amplifies DevRel when applied thoughtfully.

Additional experience at Project Discovery (open-source security automation, Series A) and Prefect (data workflow orchestration).

Served on the CNCF Governing Board (2020–2022), advising on marketing and business oversight for the foundation. Previously advised Slim.ai on open source community strategy and led DevOps transformation programs for the US Department of Defense at Orbis Technologies.

Our philosophy

DevRel is developer marketing. The primary KPI is developer adoption (monthly active developers). Everything else is a leading indicator.

The three pillars: Code, Community, and Content. A healthy DevRel program delivers on all three — not just one.

Founder-led → community-led. The most successful dev-tool companies cultivate a founder-led community that transitions into a community-led community. We help founders make that transition.

"The score takes care of itself." A great product with great developer marketing leads to adoption, which leads to leads. It's a flywheel — and we know how to spin it.

AI-native. We don't just advise on AI products — we use AI to do DevRel better. From community monitoring to content drafting to analytics, every engagement is augmented by AI tools. Rigorous human review ensures quality; AI ensures velocity.
