Finland’s Tangled raises €3.8 million, backed by GitHub’s former CEO, to build a European alternative to the US platform

Tangled, a Finnish code collaboration platform, today announced a €3.8 million ($4.5 million) funding round to scale the platform into a foundational environment for software collaboration globally.

The round was led by byFounders, the community-powered VC firm, with participation from Bain Capital Crypto and existing investor Antler. Notable angel investors also joined the round, including Thomas Dohmke, the former CEO of GitHub, Avery Pennarun, CEO of Tailscale, Mårten Mickos, former CEO of MySQL and HackerOne, and Sami Honkonen, Finnish angel investor and founder of DIAS.

Anirudh Oppiliappan, co-founder of Tangled, comments, “Tangled is built on the belief that code collaboration should be as open and social as the web itself. We are moving beyond the limitations of centralised silos to give developers a platform where they actually own their data and their social graph. This funding allows us to build the foundational layer for software collaboration where both human developers and autonomous AI agents can participate directly in the network.”

Founded by brothers Akshay and Anirudh Oppiliappan, Tangled is a social-enabled code collaboration platform that rethinks how developers work together on an open, extensible network. The duo has experience building large-scale distributed systems and code intelligence platforms at Y Combinator startups. 

According to Tangled, the rise of AI-assisted coding has led to nearly a 50 per cent increase in professional developers over the last three years. Despite this growth, the platform states that the tooling used for contribution and review remains a significant bottleneck for efficient collaboration between human developers and AI agents.

Tangled claims to address this by moving away from centralised legacy systems and building on Bluesky’s AT Protocol. This enables seamless, API-less interoperability across an open network, giving developers true ownership over their work and their professional connections. The platform is designed to allow both developers and AI agents to participate directly in the network. 

“There are several models for decentralised code collaboration platforms, ranging from ActivityPub’s (Forgejo) federated model, to Radicle’s entirely P2P model. Our approach attempts to be the best of both worlds by adopting atproto—a protocol for building decentralised social applications with a central identity,” Anirudh mentioned in a blogpost. 

By combining developer tools with social features, the platform positions itself as a European alternative to US platforms such as GitHub. It claims to focus on giving the community a choice that prioritises transparency and developer sovereignty.

Jussi Kallasvuo, Partner at Antler, commented,  “The bottleneck in software development has shifted from writing code to reviewing and managing it at scale. We backed Tangled because the team has the technical depth to build a system that manages this complexity for both humans and AI. This is a critical piece of infrastructure for the European tech ecosystem, providing a native alternative to American legacy platforms.”
