AI tools for writing code have exploded - Cursor, Windsurf, GitHub Copilot - but creating code is just step 1.
What happens next? Shipping poorly tested code can wreak havoc, threatening to break your entire application which, in today’s world, is likely built with hundreds (or thousands) of interconnected services.
Current approaches try to solve this by giving engineers personal “production-like” environments to test in (expensive) or have engineers wait in long queues for a staging environment (slow). What happens when you need an environment not only for each engineer, but each AI agent? It simply can’t scale.
Enter MetalBear.
MetalBear built mirrord - a technology that connects local code directly to a company’s cloud environment, giving engineers real-time access to every service, database, and API without having to deploy anything. It’s the only way to keep up with the speed AI is generating code while maintaining quality and reliability.
This was not easy tech to build. Co-Founders Aviram Hassan and Eyal Bukchin had to create deep, low-level infrastructure (an approach rarely seen in DevOps today) and the results speak for themselves. Teams using mirrord see:
80% faster test iteration times
30% fewer production bugs
And to say I love working with this team would be an understatement. Aviram and I trade WhatsApps at all hours, covering everything from customers to team-building to marketing strategy. The pace that he, Eyal, and the entire team are moving at is unmatched.
In today’s world where speed is paramount, MetalBear gives engineers superpowers in everything after code creation. And they’re already working with high scale customers like SentinelOne and SurveyMonkey.
Today, I’m thrilled to announce Modern Technical Fund’s investment in MetalBear alongside friends at TLV Partners and TQ Ventures in their $12.5M seed round.
As AI continues to accelerate software creation, MetalBear is emerging as a critical part of the modern cloud development stack purpose-built for the AI era 🐻
