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.

We met with several firms when looking for help with this project. Gnar stood out for a couple reasons; during our initial talks they had a grasp of the projects challenges and some good insights based on past experience for how to approach them, were willing to work in a style that matched our style and were willing to work alongside our team, making sure our engineers fully understood the code they would inherit.

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.

B2B Review from Andrew Stiefel

The Curio team has helped us evolve the Endor Labs website from selling a single product, to a single buyer, to selling multiple products to the full enterprise buying committee. Part of that included building product-led experience for platform engineers and developers alongside our existing inbound sales motion for security teams, and rapidly evolving the brand and content. The team is incredibly responsive, often turning work around same day or within a week as we prepare for major industry events and respond to industry shifts. They're fantastic partners, great humans, and I couldn't recommend them faster!

We recently worked with Bird Marketing on the full design and build of our new website, and we are delighted with the entire experience. From the very beginning, the communication and support were excellent, and the end result is exactly what we were hoping for.We want to give a special mention to Jess, who managed the design and was our main contact throughout the project. She made every stage feel smooth, clear and well supported. On the technical side, Call handled all of the development work and the Salesforce integrations with great skill. Everything functions perfectly and the technical delivery has been outstanding.The team responded quickly every time we had a question or request. Even when the scope of the website changed during the project, Bird remained flexible, understanding and genuinely helpful. Their willingness to adapt made a real difference.Now that the site is live, we are excited to continue working with Bird as we begin our SEO project, especially with Lewis, who we are very much looking forward to collaborating with.Bird Marketing has been exceptional across design, development, communication and ongoing support. We are very happy with every aspect of the project and highly recommend their team.

Ruby on Rails Review from Michael Peter Craies

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.

Mobile App Development Review from Justin Turner

Chiron Health’s core business is providing caregivers with a web-based telemedicine platform which allows them to connect with patients for routine follow-ups and similar use cases. We engaged ScienceSoft to build an Android app that complements our web-based platform for our patients. ScienceSoft developers proved themselves to be Android experts. They advised and successfully lead the way from end to end through the technical challenges and considerations with development of the Android app. ScienceSoft team was in daily contact with our developers and our method of communication was a huge factor in how successful this engagement was. I would also like to point out ScienceSoft’s solid approach to testing. The thorough testing they performed on our beta environment ensured that the app was launched without critical bugs. We have also engaged them to introduce a few enhancements to the app and would certainly consider ScienceSoft as a technology partner in further software development initiatives.

Kinematic Digital suggested an action plan to help improve our online presence. They then migrated the platform to Magento. They brought in third-party modules and extensions to improve our platforms UX and functionality. They now provide ongoing maintenance and support.The project started off a bit sluggish, but has drastically improved and is now going quite well. They're extremely responsive, regardless of time or day. On top of that, their team is knowledgeable and communicates well with us, creating a synergetic partnership. We use YouTrack for project management, and we communicate via Google Meet, Slack, and WhatsApp. We also have emergency contacts that we can use if necessary. What impressed us the most was that They assign seasoned developers to our project. As a result, tasks are completed quickly, usually within a few days, which is far better than I've experienced with other vendors.

From project planning to documentation, Kinematic Digital produced tidy and well-organized outcomes. The customer has chosen from among the several design alternatives they offered. Best practices and an optimized user journey were followed in the collaborative design process. In addition to being quick and search engine optimized, the website was completed expertly.Scrum is the project management methodology that Kinematic Digital uses. Kinematic Digital's many web technologies, such as Basecamp and InVision, allowed for open and transparent project collaboration. The Kinematic Digital team was detailed-oriented and on time. We believed that, as opposed to being a vendor, we were dealing with a real partner that shared our passion for the project's success.

Web Development Review from Yury Smykalov

There are two types of work that we would do with Kinematic Digital. One is Sitecore maintenance and operation. Consider that keeping the website up and running on a daily basis. If there are small changes we need to make, like the template of a specific page, make some configuration changes, or sometimes we change the hosting environment, such as upgrading a server, they handle that. Anything related to administration and infrastructure, we delegate to Kinematic Digital.On top of that, when we have strategic projects, we engage with them on a statement of work type of arrangement. A couple of examples of those are we switched our blog platform and the look and feel and design of the blog a couple of years ago, and Kinematic Digital handled that project, so both the design and then the technical side. More recently, we conducted a redesign of the overall branding look and feel of our website, and Kinematic Digital did that, too. They worked on both the design side of it as well as the technical deployment.

Web Development Review from Tifiny Swedensky

Agency Partner built us a pretty website... but it was slow and not technically optimized for SEO. The backend was very buggy, with many "useless" sections in the WordPress dashboard. I am a WordPress developer, but I am also the company's marketing director so we chose to have the site developed by an outside company. I spent approximately 20 hours working on the backend removing useless "features" and optimizing the site to pass the Core Web Vitals. It should've been a huge red flag when the company wouldn't show us the backend before launch. Additionally, when they launched the site they "no-indexed" the entire website! Recently, I sent a ticket to support to fix 404 pages. After getting no response for several days, I went into the site and fixed the error myself. They had the audacity to send me a "we fixed the error" email 24 hours after we fixed the issues ourselves! If you are looking for a well-built site, look elsewhere. This company is only good for pretty site that loads slow and is bogged down with junk. The company reached out and heard my complaints. There's not a lot they can do to make this right (since most of the work they left undone was finished by me), but at least they listened. They extended our site warranty to help fix any outstanding issues. I'm adjusting my rating to three-stars.

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.
