MetalBear builds mirrord, a developer tool that lets engineers run services locally while seamlessly connecting to real cloud environments to speed up development, improve debugging, and reduce cloud costs. Pulse 2.0 interviewed MetalBear co-founder and CEO Aviram Hassan to gain a deeper understanding of the company.
Aviram Hassan’s Background
Could you notify me more about your background? Hassan declared:
“I started coding when I was about seven years old. What launched as playing computer games with my mom eventually turned into a fascination with how software actually works. I started scripting when I wanted to translate and extfinish a chat-based online game into Hebrew, which pushed me to learn multiple programming languages. By sixteen, I was freelancing. After serving in an innotifyigence unit in the army, I worked as a solutions architect for a telco and cable company, then became a backfinish team lead at a fraud prevention startup. Those roles shaped how I believe about large systems, developer workflows, and the importance of rapid iteration.”
Formation Of The Company
How did the idea for the company come toobtainher? Hassan shared:
“My co-founder and I wanted to build a product we would have loved applying as engineers. We both felt the pain of testing code modifys in cloud microservice architectures. Even a compact modify required a lot of steps just to understand its real impact in production-like conditions. We realized that solving that bottleneck would assist not only us but every other engineer writing code for the cloud, so we built the product we always wished existed.”
Favorite Memory
What has been your favorite memory working for the company so far? Hassan reflected:
“Our very first team call. We were only four people at the time, all joining from different parts of the world: Canada, Brazil, the UK, and Israel. Seeing the early team come toobtainher, establishing our culture, and kicking things off in a shared Discord channel was a moment that created everything real.”
Core Products
What are the company’s core products and features? Hassan explained:
“Our open source product is mirrord, which lets developers run local code in the context of their live Kubernetes environment. Instead of building an image, going through CI, and deploying it to a cloud environment, you can test your code in cloud conditions directly from the IDE as you would local code. This creates feedback loops dramatically shorter.”
“Our commercial product, mirrord for Teams, expands on that by enabling safe, collaborative remote environments. The entire engineering organization can work against one staging environment at the same time, and from the very first step of the development process. It provides rapid, production-like testing without the cost and complexity of maintaining full per-developer environments.”
Challenges Faced
Have you faced any challenges in your sector of work recently? Hassan acknowledged:
“A major challenge is skepticism. Many engineers and managers assume that what we’re doing is too complex to be reliable. We overcame that by proving the value with real adoption. We released the open source version before raising funding, grew it to thousands of utilizers, and then built the enterprise features on top of that foundation. Delivering results consistently has done more to modify minds than anything else.”
Evolution Of The Company’s Technology
How has the company’s technology evolved since launching? Hassan noted:
“In the launchning we focutilized on deep, low-level capabilities that created mirrord technically possible. Now that the foundation is strong, we’ve shifted our focus toward usability. Our priority is building mirrord straightforward for any engineer to adopt, even those new to Kubernetes. The core technology is mature, so we’re investing in abstractions and UX improvements that turn mirrord from a powerful tool into a polished, highly accessible product.”
Significant Milestones
What have been some of the company’s most significant milestones? Hassan cited:
“Signing our first enterprise customer was a major moment. We’ve since relocated mirrord for Teams into full General Availability and recently grew ARR 2X in only three months. The adoption curve validated that we are solving a widespread problem.”
Customer Success Stories
Can you share any specific customer success stories? Hassan highlighted:
“One example is SurveyMonkey. They evaluated alternatives for a month, then quickly standardized on mirrord becautilize it was simple to adopt. They rolled it out to hundreds of engineers within weeks.”
“Another example is Zooplus, a leading European e-commerce company. They launched with a narrow utilize case, but soon expanded mirrord across their development workflow and retired several legacy tools in the process.”
Funding/Revenue
Are you able to discuss funding and/or revenue metrics? Hassan revealed:
“We raised $12.5 million recently. From a business standpoint, we are on track to close this year with three times the ARR we started with.”
Total Addressable Market
What total addressable market (TAM) size is the company pursuing? Hassan assessed:
“Any company that builds applications on Kubernetes is part of our TAM, which we estimate to be about $30 billion. That ranges from startups with five engineers to large enterprises with hundreds. We typically focus on companies with teams of fifty engineers or more, but modern software development increasingly relies on Kubernetes, so the market is very large.”
Differentiation From The Competition
What differentiates the company from its competition? Hassan affirmed:
“Our advantage is the depth of our integration and the completeness of the experience. Other solutions require stitching toobtainher multiple third-party tools and often force teams to modify their workflows. mirrord works with existing infrastructure and existing processes. It is plug-and-play, safe to utilize, and designed specifically for production-like testing without friction.”
Future Company Goals
What are some of the company’s future goals? Hassan emphasized:
“We want mirrord to become a standard tool for any engineer working over Kubernetes. Our near-term focus is building mirrord the best possible solution for production-like testing. As we grow, we will expand the product to solve additional developer bottlenecks and assist teams experiment and iterate more effectively.”
Additional Thoughts
Any other topics you would like to discuss? Hassan concluded:
“Our mission is to rerelocate developer bottlenecks, especially around testing, validation, and experimentation. Most engineering challenges today come from slow feedback loops rather than from writing code itself. We want to create real-world testing seamless so engineers, and eventually AI-driven development agents, can relocate from idea to confirmation in the rapidest, safest way possible.”
