Software Development Review from Michael Levy

Flowty is a blockchain-based platform providing various transaction services around NFTs. K-Optional wears many hats in support of Flowty including Front End, Back End, business strategy, SEO and more. The K-Optional team has been incredible to work with. They are proactive, supportive, smart, thoughtful and, most importantly, fit seamlessly into our team and company culture. To put it succinctly, we tried to hire them full-time...and then tried to buy their company to acqui-hire them. Some of their strengths include: reliability, responsiveness and creativity. There are many groups out there that can perform some version of the work we are looking for. There are not many groups that are responsive at all hours of the day, deliver consistently and able to present data-backed business strategies.

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.

Translation Services Review from Abhit

They provide consulting services for a healthcare service provider. Sidebench contributed their expertise to a comprehensive mobile application to make sure it would pass Apple Store requirements. Thanks to Sidebench`s input, the application launched on the Apple Store after the first submission. Sidebench`s response times were quick, and they were willing to accommodate a unique working arrangement. The relationship that we had was probably unique; most companies would push to do the development themselves. We only needed Sidebench`s know-how, and they were willing to accommodate us.

Plavno was creating profiles with pulling up a lot of information (clusters). Xunit-based scoring was used when setting up a .NET 2.0 project. Scoring for this format works similarly to Junit.

This development can change cluster parameters, cluster management system (current state of the object), customize vectors that lead to this cluster and make predictions.

Rubyroid Labs joined our team at a time when we were starved for Ruby on Rails devs. After a very short while, the assigned team members were taking on more and more complex code and helped bolster our development outputs. Before they joined us, our average bug response time was over 2 weeks, a value that they have helped us reduce to under 8 days, with urgent tickets being resolved within a few hours. There teams' response times regarding staff movements (e.g. replacing one of our assigned devs) as well as our queries are impressive. I would definitely recommend them to any company looking to outsource their development needs.

Their team covered everything from UX/UI design to front-end, back-end, mobile development, and project management. They have been a key part of improving how our platform looks, works, and grows over time. What attracted me the most to DeepInspire was how they learned our proprietary systems and business. They were not just completing tasks to say they were done with minimum effort. They brought in talent that we needed over the years that I would have trouble recruiting and retaining on my own. (Not having to spend time on finding talent and project managed saved a lot of energy). Overall, their team was very capable and made a big difference.

They worked closely with us to understand the needs of care homes and their residents, turning a rough idea into a working app. They handled everything from early research and design to building the MVP, always making sure it was easy to use and met care industry standards. What impressed me most about DeepInspire was their approach to truly understanding the problem they were solving. Instead of just relying on calls or documents, they joined us for an in-person visit to a care home in Nottingham. By speaking directly with residents, carers, and managers, they gained a real understanding of the day-to-day challenges in care settings. That level of empathy and hands-on involvement is rare and it made a big difference in shaping a meaningful, user-focused product.

Their team was always available, responsive, and willing to address our concerns and questions. They demonstrated a deep understanding of the healthcare domain, making them a valuable partner. What truly sets Gera-IT apart is its expertise in the healthcare sector. It was evident that they had a deep understanding of the unique challenges and intricacies within the industry, like data security and compliance with the regulations. They always provided us with a few possible solutions to implement, providing the estimation of risks and consequences. Also, Gera-IT met all deadlines precisely, so we started implementing the system as planned. I wholeheartedly recommend Gera-IT to anyone in need of healthcare solution development.

Lucrezia Spagnolo Founder & CEO at VESTA Social Innovation Technologies, Inc

Software Development Review from Lucrezia Spagnolo

I met Chris in 2019 when VESTA was just an idea on paper. From the beginning, he listened, not only to what I wanted to build but to the problem I was trying to solve. As a non-technical founder, I needed a partner who would focus on outcomes, not just the jargon, and the Ollon team did exactly that. They helped me prepare our first major funding proposal and, when the grant was secured, became our technology team. Since then, I have worked with the same small and consistent group, including Nichie, Chris Elcombe, Alan, and Darin. Chris personally joined high-level security meetings, guided technical planning, and taught me how to speak confidently about our systems and privacy approach. When we secured our second round of funding, Matthew helped lead and organize the technical hiring process. The Ollon teams loyalty, responsiveness, and professionalism have been exceptional. When an issue arises, even beyond their direct scope, someone from the team steps in to help. Their commitment and care have made them feel like part of Vesta from day one. Six years later, Ollon has grown alongside us, not just as a development partner but as a genuine part of our story.

Webflow Review from Melissa Valentino

We've partnered with Curio Digital for about five years, and they have become one of the most trusted extension teams we work with. As a creative agency, having dependable development partners is critical, and Curio consistently exceeds expectations. They have supported TDH Creative on numerous Webflow website projects, and the quality of their work is exceptional. Their development is clean, thoughtful, and technically sound, but what really sets them apart is their communication and project management. They're responsive, proactive, transparent, and consistently deliver on what they commit to. As an account lead, that level of reliability makes a tremendous difference. Curio has also been incredibly collaborative throughout the creative process. They work seamlessly with our designers and strategists, offering solutions when challenges arise while always respecting the creative vision. They don't simply execute requirements they think through the best approach and genuinely care about delivering the best possible outcome for both us and our clients. Another aspect I appreciate is their pricing. They provide outstanding value for the quality of work they deliver, and I've always found them to be fair, honest, and transparent when it comes to estimates and project scope. If you're looking for a Webflow development partner that combines technical expertise, exceptional communication, reliability, and a true collaborative spirit, I would highly recommend Curio Digital. They've been an outstanding partner to TDH Creative, and I look forward to continuing our relationship for years to come.

They're fantastic partners, great humans, and I couldn't recommend them faster!

UI/UX Design Review from Kourosh Nazari

In our quest for the perfect addition to our mobile team, someone who could dive into the deep end of mobile design with both UI expertise and a keen sense for product design, we found support from Netguru. This support person didn't just join our team; they became its heartbeat, compressing our onboarding-to-delivery timeline to an astonishing less than two weeks. Their magic didn't stop there. They breathed new life into our mobile app, then designed their way through our public website, elevating our brand to heights we hadn't imagined. And now, as we stand on the brink of weaving their talent into our product, we realize we found much more than the artistic boost we sought. We discovered a true professional, a delightful presence whose creativity knows no bounds, yet who navigates requirements with precision. Their arrival wasn't just a solution; it was a transformation.
