Developer Relations at API-First Companies.

API-first companies were among the earliest and most influential adopters of modern DevRel practice. Because their products are accessed exclusively through code, every adoption decision is a developer decision; the line between marketin…

Twilio

Twilio (founded 2008 by Jeff Lawson, Evan Cooke, John Wolthuis) is the canonical reference for API-first DevRel. Many of the field’s standard practices — heavy investment in advocate hiring, large-scale developer conference, evangelist-driven brand, executive commitment to DevRel — were popularised or perfected by Twilio in the 2010s.

DevRel team. One of the largest in the API segment. Historically led at the executive level by Carter Rabasa, then Rob Spectre, Greg Baugues, Brent Schooley, and others through different eras.
SIGNAL. Annual flagship conference, first held in San Francisco in the 2010s. By 2026 SIGNAL operates as a global builder/customer conference (May 6–7 2026 was in San Francisco, with London editions in odd years).
Twilio Quest. Gamified learning platform for developers.
TwilioCon (now SIGNAL) and field events. Substantial sponsorship presence at OSCON, JavaOne, Velocity, and developer-focused regional events historically.

SendGrid

Acquired by Twilio in 2019. Pre-acquisition, SendGrid had its own well-regarded developer relations function — Tim Falls and Brandon West (formerly at SendGrid, later at AWS) shaped a generation of API-first DevRel thinking. SendGrid’s DevRel was absorbed into Twilio’s broader org.

Stripe

Stripe (founded 2010 by Patrick and John Collison) operates a DevRel model distinct from Twilio’s: less evangelist-driven, more documentation-and-experience-driven.

Documentation. Often cited as the gold standard for API docs (stripe.com/docs). Combines reference, conceptual content, and interactive code samples.
Stripe Sessions. Annual customer/developer event (typically late April / early May in San Francisco). Includes builder keynote, hands-on workrooms, certification exams.
Stripe Sigma. Customer-facing data product used by power developers.
Stripe Apps platform. Developer-extensibility surface introduced 2021.
Patrick Collison’s developer engagement. Stripe’s CEO maintains an unusually visible developer-facing presence (blog, public discussion of internal systems, technical engagement).

Postman

Postman (founded 2014 by Abhinav Asthana) is the dominant API platform tool, with one of the largest API-development user bases globally (40+ million users).

POST/CON. Annual flagship conference (POST/CON 25 in 2025, with thousands of API developer attendees). Strong AI-and-APIs emphasis in recent editions.
Postman Student Program. Education-focused initiative for university students.
Postman Galaxy / Postman Academy. Training program with certification and badges.
Postman Open Technologies. Spec and standards work (OpenAPI, AsyncAPI, etc.).
Public API Network. Discovery directory of public APIs hosted in Postman, which functions as a major developer-marketing surface.

Auth0 / Okta

Auth0 (founded 2013, acquired by Okta 2021) maintains a high-profile developer-content-led DevRel function.

Auth0 Ambassadors. Voluntary ambassador program providing speaker travel sponsorship, meetup support, and exclusive events.
Auth0 Blog. Long-form, technically deep content on identity, security, and OAuth/OIDC. One of the standard references on the open web for OAuth implementation guidance.
Iconic team members. Christian Heilmann (former Auth0 DevRel, author of The Developer Advocacy Handbook), Sam Julien (DevRel leadership), and many active advocates focused on social/community presence post-Okta acquisition.

Algolia

Algolia Developer Experience. Strong focus on documentation and quickstart quality.
Algolia Heroes (recognition program).
Algolia Search Conference (algolia-related). Smaller-scale.
DevRel team has historically included high-profile members like Sarah Dayan and others active in front-end and search-focused communities.

RapidAPI

Mission. Largest API marketplace, also a developer hub for discovering and integrating APIs.
DevRel team output. Reportedly reached 20+ million developers in a single year (2021), per RapidAPI internal reporting. Led by a VP of DevRel during peak years.

ngrok

DevRel team. Small but technically deep. Scott McAllister (Principal Developer Advocate) hosts the Dev Roundtable video series and ngrok’s developer engagement.
Product. Secure introspectable tunnels for local development — almost universally adopted by API developers needing webhooks.

Plaid

Developer-facing API platform for financial integrations.
Plaid Connect. Annual customer/developer conference.
Significant docs-driven DevRel model similar to Stripe’s.

Box / Dropbox

Box Platform. Long-running enterprise content API; modest DevRel function.
Dropbox Developers. Maintains an SDK ecosystem; smaller scale than peak Dropbox API era (2014–2018).

Other notable API-first DevRel programs

Boomi, Workato, Tray.io. iPaaS platforms; smaller-scale DevRel.

WSO2. API management and identity vendor; WSO2Con annual conference.
Tyk, KrakenD. Smaller API gateway communities.
Mailgun, Mailtrap, Resend. Email APIs; Resend’s developer-led aesthetic is a recent particularly strong example.
Vonage (formerly Nexmo). Communications APIs; competes with Twilio. Small but established DevRel.

Cross-company observations

Documentation is the primary product surface. All companies on this list invest heavily in docs as a top-of-funnel and activation-funnel surface.
Sample apps drive activation. Stripe’s, Twilio’s, and Algolia’s sample applications are central to their developer onboarding.
Quickstart obsession. Time-to-first-hello-world metrics are intensely tracked. Stripe famously aimed for “first charge in 5 minutes.” Twilio’s “first SMS” template is replicated industry-wide.
Free tier as marketing. Generous free tiers function as the trial gate; DevRel measures activation against free-tier signups.
PLG-aligned funnels. All of these companies operate in product-led growth motions where DevRel directly contributes to revenue.
