‘Docker of integration’ raises €2.1M

A Warsaw startup called Graftcode has raised €2.1 million to sell a different way for software systems to talk to each other. (tech.eu) The round was led by Hard2beat, with DigitalOcean Ventures, Heartfelt Capital, and company employees also investing. Graftcode said the new money brings its total funding to €6.5 million and comes with the beta launch of its platform. (tech.eu) Most modern software is stitched together from separate services, languages, and databases, and engineers usually connect them with application programming interfaces, middleware, queues, and custom client code. Graftcode says that wiring work can consume 30 to 40 percent of engineering time. (graftcode.com) Graftcode’s pitch is that developers should be able to call remote code the way they call a local library. Its system generates a typed client package from a service’s public methods, then lets teams install it through tools such as npm, pip, NuGet, or Maven. (graftcode.com, dov.vc) The company calls that approach “runtime bridging,” which it says removes the need for application programming interfaces, middleware, and hand-written connectors between services written in different languages. Tech.eu reported the beta platform supports 14 programming languages, while investor materials describe support for more than 20, suggesting the product is still expanding. (tech.eu, dov.vc) That sales pitch lands in a market where companies are adding more cloud services, more microservices, and more artificial intelligence tools to the same stack. Graftcode and its backers argue that each added service increases the amount of “plumbing” code teams have to write and maintain. (tech.eu, startupresearcher.com) The founders, brothers Przemysław Ładyński and Łukasz Ładyński, started the company in 2023 after what multiple reports describe as more than two decades working on enterprise integration projects. Investor materials say that experience included work with Siemens, Intel, Bosch, and TotalEnergies. (startupresearcher.com, dov.vc) Graftcode says its software can make service interactions up to 70 percent faster than conventional web services and cut processor use sharply by replacing text-heavy exchanges with its own binary protocol. Those performance claims come from the company and its investors, and no independent benchmark was cited in the funding coverage. (startupresearcher.com, dov.vc) The immediate plan is product work, not a splashy expansion. Graftcode said it will use the funding to develop the platform further, support the beta rollout, expand language support, and push for wider developer adoption through 2026.
