Five Jars Reviews & Testimonials

Founder at Print Shoppe

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.

UI/UX Design Review from Audrey Thomas
Highland is a great partner. The sought to deeply understand our product, customers, and pain points and built a number of forward looking opportunities for us in addition to the tight scope of our project. Proactive, thoughtful, responsive, and flexible. We are a small team and found lots of value in working with Highland to get our UX refresh project up and running.

UI/UX Design Review from ✨ Liz Pisney ✨
We recently partnered with Highland on research and prototypes for a new information architecture on a volunteer resources site for our Chapter leaders.
Having over 3000 volunteers around the globe can introduce a lot of nuance and complexity to research and design processes. The team at Highland handled it all skillfully - focusing on how to deliver the most clarity and usability to our audience.
10 out of 10, I would recommend working with the Highland team!

Webflow Review from Lee Wiensch, CAE, CFRE
We had a great experience working with the team at Highland to develop a new website for the Thoracic Surgery Foundation, a charitable organization aimed at advancing heart and lung health for all. Highland worked with us to re-imagine a dated website with limited functionality, and developed a a gorgeous new site that beautifully reflects the vitality of the organization. We anticipate that our award applicants, donors, surgeons and grateful patients will be able to easily navigate the new site and have a much-improved user experience.
Jeff Blanchard and his team were exceptionally good listeners, and worked hard to create solutions for our complicated awards program. They provided good training to our team throughout the process so that we have been able to keep things updated and easily make changes now that the site has launched. I am grateful for their patience and very quick turnaround as we juggled a new strategic plan and new branding, all at the time of the website creation.
I have been continually impressed with the expertise and the innovation that Highland brings to a project like ours. It was a pleasure to launch this site -- on time and on budget -- with their excellent work and support.

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?
