Five Jars Reviews & Testimonials

Software Development Review from Jake Mackay
For quite a long time we took orders by e-mail or personally from customers. It took a lot of time, as we either made layouts by hand or printed them according to the vague requirements of clients. All these difficulties have pushed us to take a step towards the digital transformation of our business. The team of Five Jars has developed a frontend and backend for our web tool to create print layouts. The team is not afraid to take on difficult tasks!

Responsive Review from Anthony North
I was looking for companies that had experience with large educational platforms. There are some really big players in the eLearning market in Five Jars' portfolio, so I trusted their development experience. After all our platform has become more attractive to users. Over the past year, we have noticed a significant increase in daily visits, so much so that we even had to change hosting. Five Jars helped us with that too!

Small Business Review from Colin Knox
I'm satisfied with the MVP we've done with the Five Jars team. I am currently looking for an investor for this project. I love working with professionals when I don't have to dive into a whole area that I don't know. Working with the Five Jars was a real partnership where the other side fulfilled their obligations without my constant checks.

webamboos Reviews & Testimonials

Software Development Review from Francois Costa-Peretti
It's been a pleasure to work with Webamboos over the last two years, initially to build the MVP of our art marketplace and then to add new features and improve our product.At the start of our partnership, we had a few meetings with the Project Manager with whom we refined the Product Requirements and identified the core functionality for the MVP. During this time, Webamboos used their expertise to suggest improvements and point out any potential tech blockers early on.Once this was ready, the team built the MVP of the marketplace using a Javascript/TypeScript-based tech stack (Node.js / Next.js), while integrating a headless CMS (Strapi), payment processing (Stripe), and email API (SendGrid). As a product designer, I produced the designs and flows for the team to work on. Webamboos then converted the designs into functionality, working in 2-week sprints.The team actively suggests improvements rather than simply building without asking questions. This collaboration is key to creating great products, that are both technically robust and pleasant from a UX point of view. When we did run into issues (which is unavoidable when building a complex product), we could always count on the team to adapt and come up with solutions.This includes both allocating additional resources for important fixes and sharing knowledge from highly experienced team members that were working on a different project. Also, it is clear that everyone who works there is passionate about what they do, and truly wants your business to do well. This applies to everyone from the CEO (Max) to the PM (Raluca), Tech Lead (Arpad), and all the developers that have worked on FairArt at various stages (Alex, Daniel, Lucian, Laris, Mihai & Vladut). Much appreciated!In short: amazing team and fair prices - what's not to like?
