AI App Builders Reviews 51

To say Marc went above and beyond would be an understatement. What stood out most was his conviction, he never questioned whether it would work, only how to make it work. I’ll be building with him again, no question!

Marc did a great job finishing and launching my app. He was responsive, professional, and easy to work with. I’ll definitely be using him again and highly highly recommend.

I had a call with Janelle because I needed to deploy an app I created on Famous.ai. My microphone failed on the call, so it was difficult to communicate. Janelle was extremely patient and was able to guide me through getting my app set up. Marc joined in on the call to assist and they stuck with it until the app was up and running perfectly. I highly recommend using their services!

Marc is top shelf all around. Knows his stuff. Has been in the trenches for years with skills of a veteran but the enthusiasm of a rookie - a rare combination. Perhaps most importantly he is a pleasure to work with!

Marc has made it very easy for me on how to build my app. I dealt another agencies prior to Marc with not much luck. He is very easy to schedule zoom meeting with and we get right to work. I look forward to working with him as my business grows. I highly recommend his services. Cheers.

Marc walked me through my issues promptly and with expertise - taking the reigns to save time and money. He also provided for follow-up questions and issues.

Marc was tremendously helpful with quite an urgently required issue and help, calmly and quickly. Definitely very fortunate of his expertise.

You're doing a great job. If anyone needs help then reach out to Marc.

I deeply enjoy working with Marc. He is highly knowledgeable and very patient with explaining things to me in a way where I don’t feel dumb. Marc can sense when I am feeling stressed and he has a way of calming me down with his efficiency and wit. I highly recommend working with Marc because he has a passion for helping people solve problems and making this world a better place with AI.

Mark is extremely knowledgable and experienced. No only did he deliver more than expected, he was fun to work with. I am a complete novice and he helped me fully understand and felt comfortable the whole call.
Thank you Marc!

I called Marc in to get a Famous.AI project ready for launch. I’m a front-end developer and needed platform-specific support for some heavy lifting. Famous is a cracking product, but there’s a steep learning curve if you want to get things right the first time and avoid burning budget. Marc is super-skilled, great fun and works at a blistering pace. If you need the safety and security of having an expert by your side, Marc is the guy. I thoroughly recommend getting him for an initial session as early as possible in your project.

I’ve been building web apps since the late ’90s but I’m not a coder, and for complex AI builds (like my latest project), Marc’s expertise is invaluable. He’s fast, collaborative, hilarious, and packed with brilliant ideas. Highly recommend working with Marc if you’re serious about building on Famous.AI.

Building apps is a lot tougher than I thought. It takes a lot of know how. Mark knows how to build apps to your exact liking and he does it quilckly. Excellent service for my app "The-Help-App.com" It's a big app so it will take a few calls but well worth it. Mark is very easy to talk with and get along with. The entire "Done With Me Call" process was very enjoyable, I'm scheduling more done with me calls right now. I have 5 other ideas I'd like to see take off, and I know having Mark help me with them there wont be any guess work on weather or not it will happen.

I've been persisting for months with hit and miss results. Marc provided great insight into how to resolve my next few hurdles and provided great tips along the way that will no doubt assist as i go forward.

Marc delivered outstanding technical support and truly exceeded my expectations. His debugging skills are expectations. He quickly identified the root cause behind my app's error prompt and implement the perfect solution. Although the app had a clean and attractive layout, the search function was pointing to Google with limited and ineffective results. Marc immediately recognized the issue and re-coded the feature to ensure full compatibility with OpenAI. One of the most impressive parts of his work was his decision to convert the app into a website. This approach streamlined the functionality and was hands down the smartest step toward completing the project. Even more remarkable is that he accomplished all of this in just one hour and fifteen minutes, after I had already tried several unsuccessful methods on my own. Marc's efficiency, expertise. and problem-solving mindset make him truly invaluable. Highly recommend!

I came to Marc with what I thought was just a couple of issues for my site ContractorBooster.com a subscription platform that lets contractors publish SEO optimized articles and rank locally. I thought I only had a few bugs. Marc took my huge mess and went through it with me and not only fixed it but helped to teach me how to fix the next problem I created.

What blew me away:
Every bug I found was fixed often the same day, some a little longer but was still got them taken fixed.
The communication is unreal, emails, Zoom calls and messaging were super easy.

I couldn’t have done this without Marc.

If you’re on the fence, jump. Marc and AI App Builders are the real deal. 10/10, would (and will) hire again in a heartbeat.

I really enjoy the one-on-one guidance with AI App Builders. I am so excited about getting my apps up and going very soon, thanks to Marc!! I plan to be an ongoing customer. Thank you.

Great teacher, pays attention to all details and is patient.

Working with Marc has been nothing short of outstanding. From day one, he brought clarity, patience, and genuine partnership to the entire MVP build for my platform. He didn’t just execute — he truly thought alongside me and contributed some serious genius throughout the process. Every step felt collaborative, thoughtful, and supported.

The communication was clear and reassuring, especially for a project with so many moving parts. Marc is the kind of developer who listens closely, anticipates needs, sees larger possibilities before the steps leading to them even come to fruition, and then makes it all happen — all while making sure you feel confident and cared for throughout. He delivered exactly (and honestly, far more than) what we initially conceived, offered smart solutions when decisions needed to be made, and treated the entire project with real respect and professionalism.

I’m incredibly grateful for his time, his work, his sense of humor, his guidance, and the level of detail he put into bringing this MVP to life. If you’re looking for someone trustworthy, talented, and truly invested in the success of your app, Marc is the person you want on your team.

Highly, highly recommended.
