Software Development Review from Anonymous
We had created a conceptual framework to authenticate and verify the provenance, transaction history, and authorship of blockchain-based NFTs. Talentica was brought on board to test and refine the concept from both functional and engineering perspectives, and later to build a Minimum Viable Product (MVP) aligned with the agreed specifications and constraints.
Software Development Review from Anonymous
For several years, the team was composed entirely of Talentica contractors. Since January 2022, I have been directly managing them. The Talentica team handled the admin tooling backend, which included multiple Python Flask services with Postgres and Elasticsearch. These services operated in a service-oriented architecture deployed on Kubernetes, using Istio for service mesh and Spinnaker for deployments.

We have only positive things to say about their work product and attention to detail. We highly recommend them and will work with them again.
Software Development Review from Robel Yemane
I've been working with Simform for over six months now. The engagement began with bringing our subscription management platform in-house, and we've since expanded the partnership to other projects due to their broad skill set and consistent reliability. They've gone the extra mileeven over weekends and public holidaysto help us move faster when needed. Communication and project management have been excellent, with any issues swiftly addressed. It genuinely felt like Simform was invested in our success. Having worked with similar firms throughout my career, I can confidently say Simform stands out and comes highly recommended.

Rubyroid Labs Reviews & Testimonials
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.
Software Development Review from Anonymous
Rubyroid Labs conducted a code audit for our legaltech workflow automation platform. They identified several critical areas for improvement and provided actionable recommendations.

Atomic Object Reviews & Testimonials
Consumer IoT Review from Mason Ferlic
GripFusion is a sports technology startup developing Tactile Intelligence. Our flagship product, the ForceBall, is the first grip-sensing baseball. We approached Atomic Object with the challenge to build a React Native iPad app to connect with the embedded electronics over BLE and visualize sensor data in real time. Atomic stepped up to the plate and hit a home run! They took early R&D code and we're able to successfully navigate IoT challenges, large amounts of sensor data, and seamless UX. The developer team worked closely with our technical staff to incorporate evolving firmware and hardware improvements. The design team did hundreds of hours of user discovery and product feedback to ensure we deliver a cutting-edge experience. Overall, Atomic has the breadth and depth to tackle complex hardware-software systems.
Daniel Schoonmaker's Review Sourced from Google
Atomic Object is one of the best companies across the board in Michigan. Fantastic maker of custom-software solution and a model of organizational thought leadership. I've been working with the company in some capacity for nearly 20 years and learn something new in every interaction I've ever had.More than that, they are a value-centered organization that you will be proud to partner with. They've built this company the right way. An impactful community leader and employer of choice.
Rik Cordero's Review Sourced from Google
As a freelance Video Producer, I recently wrapped up another fun project with the folks over at Atomic Object, and I've gotta say, it was an experience worth mentioning. Collaborating with their marketing team on a series of authentic and engaging customer-facing and internal videos was nothing short of fantastic. Their seamless planning and logistics during pre-production, coupled with easy going personalities during production, made the process a breeze. Post-production brought our collective vision to life with meticulous story editing and videos that reflect their unique culture and values. Their team's dedication to kindness, empathy, and diversity made this collaboration not just successful, but truly enjoyable.

My husband and I own a start up and have worked with Aly, Justin, and Austin at Clique for a complete rebranding and website redesign and are now working with Jeff for continuous marketing and managing our ad spend. I can’t say enough good things about this team and this company. They are creative, innovative, dedicated, and they CARE. They treat our business as their own, asking thoughtful questions and guiding us through our growth. Our new site visits have conversion rates have skyrocketed, doing daily numbers that our old site and unstructured marketing did in months. I can’t say thank you enough to this team.

I own a marketing firm in Troy MO and I recently met with Calvin at Sketch Development Services to discuss a software development project I have been thinking about pursuing. He was very nice, easy to speak to and even though his field is a bit out of my knowledge base, he was able to explain things in a way that made perfect sense. I look forward to working with him and his team in the future and recommend anyone looking for a software or app development company to give them a try.
