History & Evolution of DevRel
DevRel didn't start as a job title. It grew out of a problem: platforms only succeed when developers build on them.
The evangelist era (1980s–2000s). Apple hired "software evangelists" in the 1980s to convince developers to build Macintosh applications. Guy Kawasaki made the title famous. Microsoft, Sun Microsystems (Java) and later Google built large evangelism teams. The model was mostly one-way: travel, give keynotes, win developers over to a platform.
The API economy (late 2000s–2010s). Twilio, Stripe, SendGrid and others sold directly to developers. A developer could sign up with a credit card and ship in an afternoon, so developer experience was the sales funnel. Twilio's "developer evangelist" team became a template: engineers who wrote code in public, answered questions, and treated time-to-first-API-call as a core metric.
Open source and foundations (2010s). The rise of GitHub, the CNCF (Kubernetes) and company-backed open source pulled DevRel toward community building and contributor programs. Roles split into advocacy, community, documentation and developer experience.
Measurement and maturity (late 2010s–now). As teams grew, executives asked the hard question: what are we getting for this? Books like The Business Value of Developer Relations (2018) and Developer Relations by Lewko and Parton (2021) pushed the field toward strategy, metrics and journey thinking. AI tooling is now reshaping how developers discover and learn products, which puts even more weight on docs, examples and trust.
Why it matters for you: each era left behind expectations that still exist. Some companies still want keynote evangelists; others want DX engineers who fix onboarding. Knowing the history helps you read a job description and see which era it's hiring for.
- DevRel began as platform evangelism and evolved toward two-way relationships and measurable outcomes
- Developer-first API companies made developer experience a revenue driver
- Job descriptions often reveal which "era" of DevRel a company believes in
