We went from an idea to a working public product in roughly three months. This is where I really love how they stand out, because every person in their team was self-organizing and could go from 0-100 in no time at all. That included the initial platform, the product interface and user-facing documentation. We were then able to expand the product into the Playground and MCP ecosystem rather than stopping at the initial deployment product. The hackathon produced more than 50 potential use cases within the first 2–3 weeks of launch. That was useful because it gave us real evidence of how developers were thinking about using agents and MCPs, rather than relying entirely on our assumptions.

The biggest thing was their ability to move between product and engineering. Illegal Agents was being built at a time when AI agent frameworks and MCP were still moving very quickly. There wasn't a mature set of tools or established patterns for everything we wanted to do. Grayhat was comfortable working through those problems directly. They could take a product idea, turn it into a design, and then go deep into the implementation when the technical problem required it. They also weren't afraid to work in open-source repositories and deal with unfamiliar codebases. That flexibility mattered more to us than simply having a team that could execute a predefined backlog.

I found their ability to understand what I was trying to build and then move very quickly from an idea or requirement to an actual implementation, very impressive. They're an all-in-one beast, kind of like a Swiss knife for founders.

Grayhat feels like a natural extension of our team. I genuinely leave most meetings with them impressed, because they almost always come back with work that is better than expected. You can tell there is a high level of care, taste, and attention to detail in how they approach things. It never feels like they are just checking a box. It feels like they actually understand what we are trying to build and care about making it great.

Yes, they have helped us across a lot of business-critical work, often under pretty intense time crunches, and the quality has never dropped because of it. Whether it is prototypes, game systems, design direction, polish, or getting things ready for partner/community moments, they consistently figure it out. What stands out most is that they do not just execute the ask. They take the time to learn our vision, our style, and the weird details that matter to us, then they build on top of that.

Grayhat always seems to have an answer. No matter the scope or discipline, they are able to get the right people together, understand the problem, and push it forward. We have worked with them across several different kinds of creative/technical problems, and they keep knocking it out of the park. They are one of the rare external teams that actually feels like part of the company.

The Grayhat team have been an indispensable asset to our startup journey at Playroom. With a need for rapid tech adoption and innovation, Grayhat possessed a wealth of skills that were a perfect match for our business needs.

Grayhat seamlessly integrated into our team, contributing their expertise in modern AI tech stacks and gaming infrastructure. Their proactive approach to collaboration and steadfast commitment to meeting deadlines have been instrumental in propelling our success. Saad and team aren't just partners; they're an extension of our team, driving us forward with their skills and dedication.

They listened carefully to our feedback, incorporated all our suggestions, and were always quick to respond.

I really like their culture. They just want to build things and ship. We literally had our first build within an hour of signing! That kind of energy is something I really appreciate. Especially when you're building games and trying to move quickly.

These guys are absolute life-savers! Websites, email migrations, you name it & they can help out. Definitely my go-to company for higher-level assistance and quick service!

We had a relatively small team of around 5–7 people, but they brought together designers and engineers who worked well as a unit. Everyone was very well-spoken, kind, and professional.

There was also a very genuine, almost homely feeling to working with the team. As founders, we felt that they listened to us and genuinely cared about understanding what we were trying to build rather than simply taking instructions and writing code.

I particularly appreciated how much attention they paid to understanding our users and the reasoning behind our product decisions.

Most of my interaction was with Talha Momin, their Software Engineer 1, and he was a great developer to work with. He was  able to pick up new patterns and systems quickly and help bring complex features to completion.

In my experience, Banana of Doom wouldn't have shipped if it hadn't been for Talha stepping up and taking on more difficult tasks. We had to re-write Playroom's Unity implementation in C# so it would work with Steam builds, and Talha was able to help bridge issues between the JS and C# versions depending on WebGL or Exe builds.

They're great engineers and also willing to deal with the time differences.

My experience with Grayhat was great. The developer was very knowledgable and was able to unwind a mess of code that was created from another company. Communication was good. She asked great questions and work was completed in a timely manner.

I would work further with Grayhat and have two website projects that will be coming up in the next month or so that I plan on engaging with Grayhat on.

I would and have recommended Grayhat because of their clear communication and the pride they take in doing a good job.

[They have] really good customer service.

Amazing work. I am continuing on working with them on other projects. They have an amazing team works to solve any issue fast and work quality is great.

Working with Grayhat on listen.dev was a great experience. Their team delivered a high-quality user interface that matched our vision and helped bring the product to life. Throughout the project, they were responsive, easy to work with, and consistently demonstrated strong technical expertise and attention to detail.

We were very happy with the outcome and would confidently recommend Grayhat to any company looking for a reliable development partner.

Experience was great, I like that they had different people coming in for relevant expertise and worked on things quite actively whenever needed.

Would definitely love to work with Grayhat in the future, both as a partner and as a client. Was especially happy with the 'wow' features they added to our website like the 3D responsive models, animated gifs, etc.

I would definitely recommend them to other companies as well because they offer quality work for very reasonable prices.

Our experience with Grayhat has been delightful. Their engineer is very talented and an eloquent communicator and has carried OnlySports very well so far. Oh, and he has a very helpful personality.

They're badass engineers, their studio helped Upstreet a lot for quite a few months.
