We had an opportunity to bring Death by AI, our flagship game with over 50 million players in its first six months, to Reddit's new gaming platform.

The challenge was timing. We had a pretty tight deadline and budget, and needed someone who could move fast without compromising the experience.

We reached out to Grayhat's CEO because we knew they had experience with multiplayer games, web game development, and shipping React-based games quickly. This was also an early-stage partnership for us, so we wanted to test the waters and see how well we could work together.

Essentially, we handed them the game and asked them to build the entire Reddit version from scratch.

RESULTS & FEEDBACK

Developed four major components from scratch: game frontend, backend, AI layer, and administration panel, alongside daily challenges and quests.

Completed 3 client review cycles with the Playroom/Little Umbrella team, incorporating feedback and refinements to meet project expectations.

Delivered additional improvements beyond the original scope, including AI safety checks, UI refinements, and architectural and performance optimizations.

Delivered a complete recreation of Death by AI for Reddit in approximately two weeks.We shipped Death by AI to an entirely new platform in approximately two weeks. That's a big milestone for us, especially given how much needed to be rebuilt. The implementation was pretty much flawless. We had a few minor tweaks during our reviews, but honestly, we expected a lot more back-and-forth considering the scope. One engineer managed to deliver the full game, including the frontend, backend, AI systems, admin panel, daily challenges, and quests. And they didn't just recreate what we already had. They also improved parts of the UI, architecture, and performance, and added extra safety checks. For us, the biggest win was being able to move quickly on a new platform opportunity without pulling our own team away from everything else we were building. 

It was honestly pretty simple, which I appreciated. We had one kickoff meeting, and after that it was mostly daily updates on Discord. The engineer understood what needed to be done and just got on with it. There wasn't even a shared task board between us. I'm sure they had their own internal system, but we didn't really need one. They kept us updated, shared builds, and we reviewed things as they came in. We had three rounds of feedback, all collected in a single document. Every time, we'd send over our comments and they'd have everything resolved by the next morning. That was great. We did go about 1–2 days over the original timeline, mostly because of operational dependencies and some challenges with Reddit's new Devvit platform. But considering what they managed to deliver, that really wasn't a concern for us. Overall, super responsive, easy to work with, and very little management needed from our side.

Email or Messaging App

I don't think they're just developers. They're builders. I mean, one engineer managed to take our requirements, understand the Figma designs and overall direction, and build an entire game with VFX, SFX, gameplay, an AI backend, and safety checks. All without constantly coming back to us with questions. That's pretty impressive on its own. But I also really like their culture. They don't seem to get caught up in formalities or processes for the sake of having processes. They just want to build things and ship. We were still working through the contract and they'd already started getting things moving. 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.

Not much comes to mind, honestly. Maybe they could've flagged some of the constraints around Reddit's platform a little earlier, so we could've planned around them. But to be fair, Devvit is still pretty new, and we were learning about some of these limitations at the same time they were. Thankfully, the Reddit team was super helpful and quick to jump in whenever we ran into something. So nothing major. Overall, a great experience working with them.

BACKGROUND

Please describe your company and position.

I am the AI Product Consultant of Illegal Agents

Describe what your company does in a single sentence.

Illegal Agents was a deployment platform for AI agents, similar in concept to Vercel, Netlify, or Cloudflare Pages, but built specifically around agent frameworks such as elizaOS and Mastra. The problem we were trying to solve was fairly simple to describe but difficult to implement. AI agents were becoming increasingly capable, but getting one reliably running, connected to the right APIs and tools, and usable by other people still required a lot of infrastructure and developer setup. Illegal Agents abstracted much of that away. A developer could select an agent framework, model, plugins and other configuration, and deploy the agent without having to build all of the underlying infrastructure themselves. As the product evolved, we also built a browser-based Playground for developing and testing agents and an MCP Registry for discovering and connecting agents to external tools. The Playground let developers iterate on agents without having to repeatedly compile or download code locally, which was particularly useful when working with rapidly changing agent frameworks.

OPPORTUNITY / CHALLENGE

What specific goals or objectives did you hire Grayhat to accomplish?

• We needed to determine what the product should be
• We needed to build the infrastructure to make it work.

Describe the scope of work in detail. Please include a summary of key deliverables.

We worked with Grayhat from the initial idea through the first public launch. Product Design: They helped turn the initial concept into a concrete product, including the product scope, core flows and early concepts. This was particularly useful because the agent ecosystem was changing quickly and we had to decide what was actually worth building. Engineering: They helped scaffold the platform and worked on the core agent deployment lifecycle and infrastructure. They contributed across the frontend and backend and worked directly with open-source agent frameworks and tooling including elizaOS, upstreet/usdk and Mastra. 
UI/UX: They designed the core product experience and continued refining it throughout development. In total, they designed 50+ screens. Agent Playground: Grayhat designed and helped implement a browser-based environment for experimenting with AI agents. Developers could configure characters, models, voices, personalities and tools, then interact with agents and iterate without repeatedly setting up the underlying project locally. The Playground also supported different runtime modes, including sequential, debounced, parallel and autonomous interactions. 
This made it possible to test both individual agents and multi-agent behavior. MCP Registry: Grayhat also designed and helped implement the MCP Registry. This gave us a way to discover and connect MCP servers to agents instead of treating every tool integration as a separate implementation. Documentation: They contributed extensively to the user-facing documentation for the platform, Playground and MCP ecosystem. Developer ecosystem: They also helped us conduct a Mastra MCP AI Hackathon at FAST-NUCES, which helped us explore practical applications of MCP and the platform with developers.

RESULTS & FEEDBACK

What were the measurable outcomes from the project that demonstrate progress or success?

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.

Describe their project management. Did they deliver items on time? How did they respond to your needs?

They always delivered on time.  They responded around the clock, and could shift their hours to meet whatever demands we had. 

What was your primary form of communication with Grayhat?

• Virtual Meeting
• Email or Messaging App

What did you find most impressive or unique about this company?

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.

Are there any areas for improvement or something Grayhat could have done differently?

I don't have any significant complaints. They consistently made an effort to do what was needed to keep the product moving, and I appreciated their willingness to take on problems outside the original scope when the project needed it.

BACKGROUND

I am the Founder/CEO of Enrichly

Enrichly is a marketplace that helps parents discover and connect with camps, activities, sports programs, and educational experiences for their children.

OPPORTUNITY / CHALLENGE

• We brought Grayhat in at a very early stage, when Enrichly was still just an idea. Our first goal was to validate the concept through user interviews and research, understand how parents discover activities for their children, and turn those insights into a prototype that we could use for early validation and fundraising.
• Once we had validated the concept, the goal was to take the prototype and turn it into a functional MVP. That meant building out the backend and frontend, redesigning and expanding the UI/UX, and creating the core two-sided marketplace experience for both parents and activity providers.

2-5 Employees

SOLUTION How did you find Grayhat? Through a previous engagement. Why did you select Grayhat over others? The biggest reasons were culture fit, honesty, and their ability to understand the actual problem we were trying to solve. We also really liked the personalities on the team. They were approachable, kind, and easy to work with, which made a big difference for us as an early-stage company. How many teammates from Grayhat were assigned to this project? There were generally around 5–7 people involved across design and engineering, depending on the stage of the project. Describe the scope of work in detail. Please include a summary of key deliverables. Grayhat worked with us from the product discovery and design stage all the way through to the MVP. Initially, they conducted extensive user interviews and research to understand parents' needs, how they discover activities for their children, and the broader marketplace opportunity. They then translated that research into the initial product experience and prototype. After the prototype stage, Grayhat developed the frontend and backend and redesigned and expanded the product's UI/UX. The resulting MVP included features such as search and filtering, interactive maps, child profiles, organization management, favorites, and different experiences for parents and activity providers. They also built the product as a PWA with a mobile-first experience, using Next.js and Express.js, giving it an app-like feel across Android and iOS.

RESULTS & FEEDBACK

RESULTS & FEEDBACK What were the measurable outcomes from the project that demonstrate progress or success? The initial prototype helped us validate the concept and raise funds through a friends-and-family funding round. From there, Grayhat helped us move from an early prototype to a functional MVP with the core marketplace infrastructure in place, including the frontend, backend, and redesigned UI/UX. For me, one of the biggest successes was that they were able to work with us through such a large transition — from an idea, to research, to a prototype, and eventually to a working marketplace product.

Describe their project management. Did they deliver items on time? How did they respond to your needs? We had weekly standups where the team presented their work, and the meetings were always well structured. There was a good balance between design and engineering contributions, and they paid close attention to our direction as founders. They also made a genuine effort to understand our target customer. Since we were building for parents in the Midwest, particularly around children's education and activities, this required understanding the psychology and day-to-day needs of a very specific audience. One of the engineers on the team was herself a working mom, and she did a brilliant job of understanding our requirements and looking at the product from the perspective of our users. That kind of empathy was particularly valuable.

Virtual Meeting

The people and the culture were probably the most impressive part. 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.

There are always things that could have been done better. In hindsight, we could have scoped certain things more clearly at the beginning, and I think there were opportunities to make greater use of AI to speed up parts of the development process. Given my own schedule as a founder, I also would have appreciated more support on some of the business-side aspects of the project. The lead was great, and I would have loved the same business energy from the rest of the teammates. That said, Grayhat remained professional throughout the engagement, and overall we had a very positive experience working with them.

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.

Virtual Meeting

What did you find most impressive or unique about this company?

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. 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 feel like part of the company.

Are there any areas for improvement or something Grayhat could have done differently?

We probably could have saved some time by tightening the scope on some ambitious projects earlier on. Still, I love the "we will figure it out" attitude everyone brought to the table.
