Graftcode, a Warsaw-based integration-free development layer, has raised €2.1M in seed funding led by Hard2beat Ventures. The platform enables developers to call methods across languages and microservices as local dependencies without APIs or glue code. The capital will expand language support, AI workflows, and platform development.
Seed Wave Hits Dev Integration Tools
The round brings total funding to €6.5M and coincides with Graftcode's beta launch. It arrives amid investor interest in developer tools, where Buf raised $93M and Fermyon secured $26M. Temporal has raised over $600M. Graftcode differentiates by eliminating APIs entirely via runtime bridging.
Integrations Consume 70% of Dev Time
Developers spend up to 70% of their time on integrations, per Startbase coverage. Microservices complexity wastes 30-40% of dev effort on plumbing code. Current solutions like gRPC require heavy IDL definitions and code generation. This leaves less time for business logic amid AI-driven demands.
Runtime Bridging Replaces API Boilerplate
Graftcode's gateway exposes backend methods, auto-generating strongly-typed clients installable via package managers in 20 languages. Grafts update automatically without recompilation. It supports monolith-to-microservices shifts via config changes alone. Enterprises like IBM, Siemens, and TotalEnergies already use it, gaining 70% faster interactions and 1/8th CPU usage versus REST/gRPC.
AI-Ready Without Extra Middleware
The platform simplifies AI orchestration by making services consumable as local calls. No queues or SDKs needed for cross-runtime execution, such as Python with .NET and Java in one process. This positions Graftcode for agentic workflows where AI agents direct services.
As Przemysław Ładyński, CEO noted:
"For two decades, the software industry kept optimising how systems connect rather than questioning whether that complexity should exist at all. We built Graftcode to remove the integration layer entirely… systems become immediately ready for AI consumption without any additional work."
Hard2beat Leads with Strategic Backers
Hard2beat Ventures led the round, joined by DigitalOcean Ventures, Heartfelt Capital, and employees. This mix signals conviction in deep-tech dev tools from Polish investors. Total €6.5M enables scaling beyond early traction with Fortune 500 users.
Data Integration Market Scales to $109B
The data integration market stands at $19.15B in 2026, projected to reach $108.76B by 2034 at 24.2% CAGR, per Peliqan. Software development tools hit $7.44B with 16% CAGR, via Mordor Intelligence. Trends like AI agents and modular monoliths drive capital here.
Brothers Evolve Javonet Into Graftcode
Co-founders Przemysław and Łukasz Ładyński bring 20+ years from SdNcenter and Javonet, which served IBM and Siemens. Przemysław invented Javonet's runtime bridging, now core to Graftcode. Their track record provides perfect founder-market fit for polyglot integrations.
Beta Targets 200K Users by 2026
Funds support more languages, AI/MCP hosting, and Vision monitoring portal. Beta launched with free developer access across major clouds. Startbase notes ambitions for 200k users by year-end, building on 400+ Grafts generated in alpha.
