Software Development Review from Claus-Peter Mueller
We have engaged Infinum to develop an app that would digitalise our leasing process. From creating the initial offer through the necessary financing application and client identification to the final signature – all the steps required to successfully lease a vehicle or other object can be performed in-app, freeing the users of friction and having to deal with tedious paperwork.The app itself in the background has 30+ integrations, while keeping a seamless and quick to follow process on the front for our users. That application is in production and Infinum is responsible for maintaining it and further improving. After the initial development, we have additionally expanded our scope from vehicles to other equipment. They have also developed a Leasing widget, product which enables quick financing model while purchasing a vehicle online on car seller marketplace pages. At this moment, we are still in partnership with Infinum, and their engagement is mainly focused on localising the app to other countries and supporting us in our further business expansion. The work performed was done in Ruby on Rails and React technology, with support of other services.

WooCommerce Review from Amanda Viviano
We hired Qolos to build our local florist shop's website on WordPress and WooCommerce, and we couldn't be happier with the results. From the start, they took the time to understand our business and created a site that's not only beautiful but easy for our customers to browse and shop.The WooCommerce setup was seamless, our online ordering works exactly the way we needed it to. But what really sets Qolos apart is their ongoing monthly maintenance. We never have to worry about updates, security, or technical issues because they stay on top of everything. Any time we've had a question or a small change request, they've been responsive and professional.As a small local business, it means a lot to work with a team that genuinely cares about keeping our site running smoothly. Qolos has been a true partner, not just a vendor. Highly recommend them to any local business looking for reliable web design and maintenance!

Web Development Review from Sanjay Singh
I kept getting negative reviews about my app for technical glitches, heating issues, functionality, loading time, crashing, and more bugs. So, I reached out to QOLOS after going through 2-3 renowned review platforms. I explained my app issue to the team, and they did tremendous work with their mobile testing solutions. Also, I wanted to build a website for my app. They created a feature-rich and seamless website.

Shopify Review from Sarah Nesheim
Working with QOLOS was the best decision I have made in regards to scaling my business. They are professional, so creative, they communicate every step of the way and their pricing is fair for the highest quality work. The designer of our logo and website did it well and I am so impressed and proud of the final product! the designer listened and knew exactly what I wanted which made the process so simple. Seriously could not recommend QOLOS more!

Mobile App Development Review from Artur Ozierański
JetRuby provided staff augmentation services for us. developed a mobile app for a design platform. The team was responsible for implementing the backend server and admin panel, and frontend code. The team was made up of experienced developers that have great communication skills, which made resolving any issues or questions a breeze. JetRuby developers kept up-to-date with the latest technologies and trends in development and suggested updates and improvements to the application as needed.

Web Design Review from Patrice Archer
They developed a SaaS web platform with smart scheduling and automation tools for us at and built the platform's front- and backend and integrated a custom analytics dashboard and calendar integrations. But to be honest what impressed us most was how deeply they engaged with our vision. They didn't just write code they challenged assumptions, proposed better workflows, and contributed as if they were part of our internal product team. Their ability to think strategically and focus on user experience made them feel more like tech partners than a typical outsourced vendor.

Twenty Ideas Reviews & Testimonials

Startups Software Development Review from Justin Collins
Our first engagement with Twenty Ideas was accurately scoped and allocated from day one, and that was impressive. Being on time and budget while exceeding expectations seems impossible for many vendors, but with Twenty Ideas, there were zero issues. They anticipated our needs and presented clear options when necessary.

Mobile App Development Review from Rachel Efron
The most impressive thing was the collaboration we established. I had been creating this app by myself for so long, and all of a sudden, I had a whole team of thought partners. Twenty Ideas really got in there with me, learned what I was trying to make, and collaborated with me on it. It was an extremely rewarding experience, and we're thrilled with the app!
Jana DiSanti's Review Sourced from Google
I started working with Twenty Ideas in a part-time consulting capacity, but I became so taken with the team’s passion, mission, and supportive culture, that I ended up applying for a full-time position. I’ve been with the team for three and a half years now, and it’s given opened doors to expand my skill set; work with smart, kind, and dedicated people, every day; and work with clients who truly care about making a positive impact, to create life-changing solutions together. It’s a great place to work!

Software Development Review from Harshal Chhajed
They have highly skilled support staff for faster resolution which leads to customer satisfaction. Also, it has many features including IoT and blockchain apart from regular software development. If there are any changes in the scope of the project at a later stage, it can prove quite costly and also difficult to accommodate last-minute client-side scripting changes. They are versatile, cost-effective, and offer quick customer support. They offer a very customized software development tool where business needs can be addressed. It is very cost-optimized and hence can help generate good returns for business investment.
