A fledgling open supply startup that’s getting down to deal with API sprawl within the GraphQL ecosystem has secured the backing of e-commerce big eBay.
WunderGraph, as the corporate known as, as we speak mentioned it has raised $7.5 million in a Collection A spherical of funding to “scale its open supply GraphQL federation.”
Traders embody eBay’s VC arm eBay Ventures, Karma Ventures, and Aspenwood Ventures. Along with investing within the startup, eBay can also be serving as a core design associate as WunderGraph has set about constructing an open supply different to rival merchandise from GraphQL firm, Apollo.
“Our funding in WunderGraph’s extremely performant open supply platform will assist increase eBay’s API ecosystem and allow our groups to work sooner and smarter in constructing merchandise that assist our sellers thrive,” Bryan Woodruff, eBay’s VP of vendor expertise engineering, mentioned in an announcement.
Based in 2020, WunderGraph is the handiwork of CTO Dustin Deus, CEO Jens Neuse, COO Björn Schwenzer, and CCO Stefan Avram (pictured above, left to proper).
Whereas three of the corporate’s founding quartet are based mostly in Germany, the corporate has been included within the U.S. since its inception. Miami-based Avram joined the ranks in 2022 to make sure the agency has on-the-ground management within the U.S.

There’s an API for that
GraphQL, for the uninitiated, is a knowledge question language for APIs (software programming interfaces) that was developed at Meta (then Fb) again in 2012 as a part of its transition from internet wrappers to native cellular apps. The corporate open sourced GraphQL in 2015, and later transitioned the challenge to its personal namesake basis beneath the auspices of the Linux Basis.
In easy phrases, GraphQL lets purchasers (i.e., purposes) request the precise information they want as an alternative of over-fetching information, which will increase bandwidth utilization and prices, or under-fetching, which can require it to make a number of requests to get all of the required information. This makes it extra environment friendly in comparison with conventional REST APIs.
Extra broadly, GraphQL helps the API economic system as software program gravitates towards microservices — purposes put along with purpose-built elements which are simpler to keep up than monoliths of code. However as an software grows and the variety of APIs develop, this could create an unwieldy mess that’s tough to orchestrate at scale.
WunderGraph has gone by way of just a few iterations through the years. It initially constructed a software program improvement package (SDK) to allow builders to unify a number of APIs, together with GraphQL, REST, SOAP, and databases similar to MySQL. Quick-forward to 2023, and the corporate raised a $3 million seed spherical to energy the API revolution by constructing what it referred to as a “GitHub for APIs” — a platform for folks to collaborate, share and discover APIs.
In the meantime, Apollo had raised an enormous sum of money to gas its GraphQL federation efforts, which is all about serving to a number of groups work and construct graphs collectively on bigger purposes as a part of a distributed structure. On the tail-end of 2021, nevertheless, Apollo additionally modified its federation product from an open supply MIT license to a proprietary “supply obtainable” Elastic License.
That is the place WunderGraph noticed its alternative to pounce.
“By the summer season of 2023, it was getting robust, as a result of we weren’t getting the offers we wanted and the entire operation wasn’t going within the route we needed it to,” Neuse informed TechCrunch.
Because the founders scrambled to show issues round, they checked out numerous gross sales notes and seen that prospects stored mentioning the Apollo license change.
“Our information confirmed that some folks had been actually on the lookout for an open supply different to Apollo Federation,” Neuse mentioned. “We figured our present method just isn’t working, so let’s simply put out an open supply different to Apollo Federation.”
So in late 2023, WunderGraph debuted Cosmo for that categorical objective.
The eBay issue
As with nearly each vendor-led open supply challenge, WunderGraph is the core maintainer and contributor of its open supply effort. On prime of Cosmo, the corporate sells internet hosting and premium assist and providers, which could embody assist with integrating databases, analytics, authentication, and observability.
Bigger firms can, in fact, construct their very own model of Cosmo in-house. But when an organization’s core focus is, say, constructing an e-commerce market, it might most likely reasonably not must develop and keep each aspect of its stack — it might use Cosmo as an alternative, and pay WunderGraph for assist backed by strong service-level agreements (SLAs).
That is the place WunderGraph’s partnership with eBay has confirmed fruitful. It’s mainly a two-way course of whereby eBay will get the flexibleness of an open supply GraphQL federation that fits its wants, and WunderGraph will get the direct design enter from a global-scale juggernaut.
“I might say we’re specialists in federation, however we don’t have expertise in eBay-scale issues,” Neuse defined. “And so by having this very shut relationship, they taught us every little thing by way of how we have to construct our product in order that it may be built-in into firms like eBay, as a result of they’ve very particular necessities.”
Such necessities may contain integrating an organization’s personal techniques and instruments with Cosmo, for instance if it solely needs to make use of components of the product. This additionally satisfied Neuse and group that open supply is the way in which to go in the event that they needed to draw big-name prospects that don’t need to be locked right into a proprietary product.
“They [eBay] actually helped us flip Cosmo right into a product that can be utilized by any massive enterprise, as a result of proprietary options attempt to transfer you right into a walled backyard ecosystem,” Neuse mentioned. “This market must be as extensive as doable. How can we appeal to all people? It should be open supply. We can’t restrict how folks use it.”
With the recent $7.5 million within the financial institution, WunderGraph says it’s planning to develop its present 20-strong workforce and double down on its open supply GraphQL federation with further instruments that assist distributed groups work extra neatly — this implies higher assist for collaboration and governance for bigger enterprises.
“Open supply is the way forward for API administration, and enterprises are demanding transparency, flexibility, and management,” co-founder Stefan Avram added. “We’re constructing the important plumbing for the world’s greatest platforms, and this funding permits us to scale whereas protecting our dedication to open supply improvement.”
