AppMakers USA Reviews & Testimonials
Awital Ifrah Program manager at Masa Israel journey
5.0★
Cross-Platform Review from Awital Ifrah
Masa came in with a pretty loose idea and AppMakers helped turn it into something solid. What I appreciated most is they didn't overcomplicate it or try to make it into some giant monster platform. They listened, asked smart questions, and helped us focus on what would actually matter for alumni and current participants. The end result felt thoughtful and realistic. I'd definitely work with them again.

Moishi Stern Customer support at Madlan
5.0★
Startup Review from Moishi Stern
We create live events. We wanted a site that shows what we do without making people dig. AppMakers listened, trimmed the fluff, and gave us pages that read fast and look good on a phone. The quote form asks the right things and our team can update galleries without calling a developer. They stayed on schedule and answered messages the same day. The whole process was calm and clear. We already see better inquiries. It feels like a real upgrade, even before the full rebuild.

Chris Bailey Director at BAILEY SERVICES LTD
5.0★
Web Development Review from Chris Bailey
I engaged their web-development team to rebuild and modernize our company's manufacturing website, and the experience has been exceptional. From the outset, communication was clear and responsive: they took time to understand our industry-specific compliance needs and translated them into a site structure that is clean, secure, and easy to navigate. Delivery was on schedule, and the final result exceeded expectations pages load quickly, the design feels professional and trustworthy, and the content layout supports clarity for both clients and regulators.In addition, the team proactively suggested helpful enhancements: mobile optimization, streamlined navigation, and improved documentation pages all of which have already resulted in noticeably increased user engagement and lower bounce rates. They handled feedback promptly and implemented corrections without fuss, making the collaboration smooth and efficient.Overall, this project added significant value to our online presence, giving us a polished, modern website that accurately reflects our manufacturing standards and commitment to quality. I would gladly work with them again and recommend their services to anyone seeking reliable web development for regulated-industry clients.

Matt Hobbs Chief Product Officer at Canopy
5.0★
Software Development Review from Matt Hobbs
I am writing to recommend EffectiveSoft, a technology consulting company that has been providing services to Canopy for the last four years. During this time they have consistently demonstrated professionalism, expertise, and a strong commitment to meeting deadlines for our business outcomes.. Canopy’s mission is to improve the financial resilience of UK renters, and support the Agents and Landlords they rent from with our powerful referencing platform. EffectiveSoft has been a key partner, working with us to deliver our product and engineering roadmaps as we continue to grow and scale. Their skilled team of engineers has worked to understand our unique product needs and deliver quality platform increments following agile principles.One of the most impressive qualities of EffectiveSoft is their ability to respond flexibly to our changes in direction, and meet evolving delivery deadlines, overseen by Kirill Makarenko, our technical project manager. Kirill and the team’s strong work ethic, capability and diligence has been crucial in the successful execution of our projects. It is rare to come across an external development team that remains steadfast in its commitment to service standards and business continuity, and here EffectiveSoft have excelled. Based on our experience, I would highly recommend EffectiveSoft for any organisation seeking technology delivery services. Their dedication, responsiveness, and commitment to delivering results make them an invaluable partner.
