Software Development Review from Michael Meyer

We were so positively surpised and happy about Sigmas services - as usual I might add. It is a pleasure working with their software engineers. After we provided a briefing, the effort estimation came right away. Shortly after the project started we could see first tangible results. The code quality was excellent and comprehensive. Minor feedback was implemented right away. What can I say more: 10 out of 10 points!

Web Development Review from Victoria Lee

I can count on one hand the number of companies Ive worked with in my career that possess the same level of dedication, responsiveness, attention to detail, and trustworthiness as that of an internal team and thats because theres only one: Handbook.First and foremost, Id like to say that if you're considering working with Handbook for your design and/or website development needs, you absolutely will not regret it. The Handbook team goes beyond simply executing our requests, which has not only been refreshing but has also been key to our growth as an online SaaS business.Handbook genuinely cares about our user experience, website performance, and broader business goals. Instead of just implementing what we ask for, they actively evaluate our needs and offer thoughtful recommendations to improve our outcomes.In addition to the quality of work and forward-thinking perspective, we know that we can count on Handbook to be there when we need them. From countless late-night sale asset takedowns to weekend staging QAs so we can feel confident about Monday morning launches, I have never experienced this level of communication and dedication from a company.I would recommend Handbook time and time again to absolutely anyone in need of web development, design, or messaging support. These guys are a rare find and your only regret will be that you didn't start working with them sooner.
