Oversight of our databases have always been a challenge. Finding the skillset to properly administer the systems is both difficult to find and high priced for a mid-sized organization. We reached out to Emergent to find out more about their virtual dba services. Their services sounded to be exactly what we needed. That was over 4 years ago. Since then we found Emergent to be a key partner in helping us in administration of our databases. Our systems are highly efficient, highly available and we feel secure knowing they are under the oversight of some amazingly skilled engineers.

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.

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.

WOW! Working with Crema was a dream come true -- literally! Rarely have I had the opportunity to engage with a partner who so actively listens to its client's vision, considers ways address the request, then magically brings it to life with such finesse... that's exactly what Crema did. With a tight turnaround time and a very public launch, Crema created a beautiful user interface, backend database, and promotional display that activated my product and made it fun and easy to use while perfectly representing my brand. I am so grateful to Crema and will continue to seek opportunities to work with this innovative, creative, and positive group of professionals.

Evan Harmon's Review Sourced from Google
Every experience I've had with Crema has always been a positive one. And every employee I've met there have been incredibly nice, thoughtful, and great to talk to. They have a very cool office space in the Crossroads with great views of KC that just makes you want to hang out there! Crema seems to highly prioritize their company culture by putting on events and having a heathy work/life balance. In short, they seem to really care about people and that carries into their work, judging by how I was able to see their process for developing solutions for their clients at a workshop they held. Using the design sprint methodology, and healthy doses of design thinking, humanistic perspectives, diversity, and pragmatism, they clearly have spent a great deal of effort honing a highly efficient development strategy that makes finding creative solutions a reliable science. It gave me a lot of ideas to bring back to my own projects and meetings! I definitely recommend their design sprint workshop and can only imagine they would be a great company to have tackling your company's challenges.

The Crema office is very cool. Lots of modern touches with a great view of the Kauffman Center for Performing Arts. I recently attended a Design Sprint workshop and had a great time! It was a unique experience and a great tool for solving even the most complex problems. I'm hoping to utilize it in my current role. Justin was a great facilitator and I would recommend using Crema for any Design Sprint needs or even attending the workshop yourself. It was also a great networking opportunity. Highly recommended!

Frequently Asked Questions About Software Testing Companies
What services do software testing firms provide?
Software testing companies provide different testing services to identify errors, security risks, performance issues, and how the software behaves in real-life situations and across devices. As part of their software testing service, they also check if each feature works as expected, fix bugs, make improvements, and make sure new software development updates don’t break existing functions, so the software quality remains stable.Â
Hourly rates for QA testing range from $25 to $200+. The final cost is determined based on the size of the software or application, its complexity, required testing type, tech stack (custom-built and older legacy systems cost more), and niche. Â
The rate will also depend on the seniority of the software tester. Across the United States, junior quality assurance (QA) tester may charge $70 to $110 per hour, while the rate for a senior QA mentor and automation engineer can range from $130 to $200 per hour. Â
Special software testing services such as QA audit goes from $5,000 to $25,000.Â
How can businesses know what type of software testing do they need?
Businesses can determine what type of testing solutions they need based on the potential impact of failures and the likelihood of defects. Namely, if they encounter:Â Â
Core functionality issues: Use functional testing to verify features work as expectedÂ
Unstable code or new features: Use unit testing for individual components and integration testing for modules working togetherÂ
Poor system stability after updates: Seek regression testing to make sure new changes didn't break existing featuresÂ
Performance and load issues: Use performance and load testing to evaluate speed and scalabilityÂ
Security issues: Security and penetration testing are commonly used across apps handling sensitive user dataÂ
Hard-to-navigate user experience (UX): Pursue usability testing to determine how intuitive the application is for end usersÂ
Low compatibility across devices: Compatibility testing can evaluate how good the app works on different browsers, devices, and OS versionsÂ
There is also the option to choose between manual and automated testing. Â
Is automated testing more expensive than manual testing?
As an investment, automated testing is pricier than manual testing but offers a lower cost-per-test over time as it can run the same scripts repeatedly, without human intervention. Conversely, manual testing entails lower upfront fee, but its cost grows linearly as the project grows, as every test cycle requires paid hours from QA testers. Â
So, for short-term projects or ones with shifting requirements, manual testing is considered a more economical option, whereas for maintenance and regression cycles, automated testing grants better return on investment.Â
The main distinction between these methodologies is that manual testing relies on human observation and interaction to identify defects, whereas automated testing uses software scripts to compare outcomes against predicted results. Â
Manual testing is best suited for exploratory testing, usability assessments, ad-hoc bug hunting, and minor hotfix verifications where script development would be inefficient. Automated testing, on the other hand, is primarily used for regression testing to make sure the new code does not break existing features.Â
How do businesses measure the effectiveness of software testing?
The effectiveness of the software testing is measured via:Â
Code coverage: The percentage of the code that has been testedÂ
Defect density: The number of defects found per unit of codeÂ
Test case effectiveness: The percentage of test cases that identify defects; helps prune redundant and ineffective testsÂ
Time to detect and fix defects: The time it takes to identify and fix software defects and software bugsÂ
Defect leakage: The number of bugs that "escaped" to production versus those caught during the testing phase Â
