About Guillermo Quintero
I\'m a product leader with 10+ years of experience building API products for developers, with a focus on identity, authentication, and communication platforms. I’ve shipped scalable, revenue-generating APIs used by global tech companies like Airbnb, Snapchat, and Uber.At Vonage (an Ericsson company), I led the launch of three new 5G Network APIs in under six months—owning product strategy, technical requirements, and SOC2 readiness in a fast-changing, highly regulated environment.I’ve managed full product lifecycles—from roadmap and pricing to documentation and customer onboarding. I specialize in building and launching 0-to-1 products that require alignment across engineering, legal, compliance, and customer-facing teams.I collaborate closely with engineering, sales engineering, and developer relations to ensure our APIs are not only performant and secure, but also easy to implement and scale.
