Overview

OneGraph was a San Francisco-based developer tools startup founded in July 2018 by Sean Grove and Daniel Woelfel. The company built a single GraphQL endpoint that aggregated dozens of SaaS APIs — Salesforce, Stripe, GitHub, Clearbit, Gmail, Twilio, Zendesk, and more — into a unified interface, handling authentication, parallelization, caching, and queuing behind a single request. It participated in Y Combinator's Summer 2018 batch and later raised a seed round from SignalFire and Perceptual Networks before being acquired by Netlify in November 2021.^[1]

OneGraph built genuinely useful infrastructure, but it operated as a two-person team in a market that rewarded either massive API partnership scale or deep platform embedding. The company never publicly disclosed revenue, user counts, or growth metrics — a silence that, combined with a sub-$1M headcount and no evidence of a sales function, suggests the business never reached the scale needed to survive independently.

Netlify acquired OneGraph on November 17, 2021, simultaneously with closing a $105M Series D at a $2B valuation — a signal that the deal was a strategic capability purchase, not a distress acquisition.^[2] Both founders joined Netlify in senior engineering roles. The outcome was a clean acqui-hire with a technology integration story attached: OneGraph's infrastructure became Netlify API Authentication, and its founders briefly led API ecosystem strategy before moving on to other ventures.

Founding Story

Sean Grove arrived at OneGraph with a résumé that read like a tour of developer infrastructure. He had co-founded Bushido, a developer tools company in Y Combinator's S11 batch, then worked at Sauce Labs — a cross-browser testing infrastructure company — and built PayGarden, a gift card payment platform.^[3] Each stop gave him direct exposure to the same recurring problem: integrating a product into third-party SaaS APIs was painful, repetitive, and never got easier regardless of how many times you did it.

Daniel Woelfel brought complementary engineering depth. The two founders do not appear to have published a detailed account of how they met, and no public record documents the specifics of their early working relationship or division of responsibilities. What is documented is the shared experience that drove them to build: "At different startups over the years, both of us had to integrate our products into dozens of other services, like GitHub, Salesforce, Stripe, Marketo, Clearbit, etc."^[4]

The founding insight was precise and structural. Grove and Woelfel observed that the world's SaaS data was not actually connected — the connections between services like GitHub, Twitter, Salesforce, and Hacker News were all implicit, buried in individual API documentation, authentication schemes, and rate-limiting rules. GraphQL, they argued, could make those connections declarative: "there is no explicit graph connecting the world's data."^[4] OneGraph would be that explicit graph.

They applied to Y Combinator's Summer 2018 batch and were accepted — Grove's prior YC experience with Bushido likely gave him pattern recognition on what the application process required and what YC partners would find compelling in a developer tools pitch. The company incorporated in 2018 and launched publicly on Hacker News on July 27, 2018, just weeks into the batch.^[5]

The initial vision was broad: a unified API layer for all of the internet's services. There was no explicit pivot in the founding narrative, but the product's evolution — from a general-purpose GraphQL aggregator to a Jamstack-aligned auth and API layer — represents a meaningful strategic narrowing that happened gradually between 2018 and 2021. The team remained at exactly two people throughout the company's independent life.^[6]
