Why We Invested in Tangled

TLDR

• byFounders led Tangled’s €3.8M seed round, backing a next-generation code collaboration platform built for human-agent multi-actor workflows.

Key Takeaways

• Tangled is founded by brothers Anirudh and Akshay Oppiliappan, who have 10+ years building distributed systems and developer tools at YC-backed startups.
• The platform replaces mutable pull requests with turn-based, immutable code reviews, adds reproducible CI, semantic code search, and portable identity via Bluesky’s AT Protocol.
• AI-assisted coding has driven a nearly 50% increase in professional developers over three years; Tangled targets the agent-scale throughput that GitHub-era platforms were not architected to handle.
• AT Protocol enables federated, interoperable identity so developer contributions and reputation are portable across an open network rather than locked to a centralized host.

Why It Matters

• Existing platforms have mutable PRs, brittle CI, and centralized identity – structural constraints Tangled attacks at the architectural level, not the UI layer.
• Multi-agent systems generating and reviewing code continuously exceed the rate limits and coordination assumptions of today’s platforms; Tangled’s primitives are designed for that load.
• Built on a public protocol with portable identity, Tangled bets that open infrastructure, not platform lock-in, is the durable position in a multi-agent development world.
