The team at BLL went above and beyond. They took my app idea and designed/developed it with lots of thought and care. The planning and "sprints" were well organized and we kept on-target with frequent catch-ups & project management tools. Looking forward to launching the app to the public with their support.

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!

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!

Si Muddell's Review Sourced from Google
Fantastically positive and driven team who on every interaction you just know care deeply about a) what they do b) what they deliver and c) ultimately the experience the end user will have.
Hugely impressed with their personal, creative and energy driven approach at the pitch stage, I commissioned 3SC to help us better scope an app. Their task was to take an in-house developed app prototype, and turn it into a fully fledged technical specification with user stories, MoSCoW prioritisation, costs, and an updated look and feel; all done with audience need at the heart.
Myself and the wider team have nothing but very good things to say about 3SC. When reflecting on an agency to work with, loads say they can do it, some can actually do what they say they can do, even less do it in the spirit of real partnership and mutually respect/drive. 3SC do all of these excellently. I highly recommend them.

IT Consulting Review from Anthony Scotney
Our experience with Mindhind has been nothing short of outstanding. As a consulting firm, we needed more than just a software developer, we needed a partner who could grasp complex strategic methodologies and bring them to life through technology. Mindhind’s team delivered exactly that. Their deep expertise in AI and machine learning allowed them to build a tool that is not only reliable but also delivers measurable value to both our firm and our clients.
The way they executed the project was exemplary. Everything was completed on time and within budget, reflecting their strong project management skills. Communication was clear, transparent, and always focused on solutions. The platform they created has become a vital part of our mission, helping us seamlessly align IT strategy with organizational excellence. We are truly pleased with this partnership and the impact it has had on our work.

IT Consulting Review from Michael Orenstein
As our product grew, managing our systems became more and more challenging. Things were slowing down, and small issues kept piling up into frustrating delays for the team.
That’s when we turned to MindHind. They took the time to carefully review everything we were using, explained what was breaking and why in a way that was easy to understand, and guided us through setting up better processes. They didn’t just fix problems, they showed us how to make the system stronger so we wouldn’t keep running into the same issues again.
Since partnering with them, our platform runs smoothly and our team feels far more confident. MindHind has proven to be a reliable partner, and we’re genuinely glad we chose to work with them.

The AppIt team has been a project-saver for our company. I went with AppIt because I was looking for a trustworthy, transparent partner to guide me (an app-dev newbie) through building a new feature for our mobile app. Their quality of work, customer service, ability to meet timelines, and transparency has been phenomenal. Highly recommend Kayla and the AppIt to any company needing development help.

As fellow Colorado Companies to Watch winners, our team met Amanda and her team in 2022 and its been a match made in heaven! We have our own in-house development team that is swamped with working on our web application, Kanso, and did not have the bandwidth to work on sub-applications and portals. Here's where AppIt came in to save the day!
We are closing out our first project with AppIt, and we are more than impressed. The application is clean and beautiful. Their team has been a joy to work with and I look forward to our check-ins on progress. This project has been so successful we have lined up a handful projects to continue this business relationship.
Kanso Software is very grateful for AppIt!

I have worked with AppIt Ventures on two different enterprise size solutions. Throughout my career and have worked with several development teams. AppIt Venture stands out above the rest.
The extraordinary service provided by AppIt Ventures starts at the top, with their CEO Amanda, and is executed throughout the entire team. It’s clear their employees are empowered to make decisions, take care of their customers, and provide the customer service their leader promotes.
Kayla, our outstanding project manager is creative, reliable and detail-oriented offering guidance and support to ensure all of our development’s needs are on track and being done with our greater vision and application needs in mind. If any bugs pop-up, which is bound to happen, AppIt's team is on it and has the issue quickly fixed or a solution put into place within hours. With AppIt's development team, I have peace of mind knowing we can quickly and easily adjust to our customer's requests and provide an unparalleled customer and participant experience.
I highly recommend using AppIt Ventures and look forward to continuing my partnership with them.

Meals on Wheels Central Texas's Review Sourced from Google
Trademark Media helped us bring our vision to life. They took a lot of information and organized it into a visual rhyme and rhythm so that when people get to our site they know exactly how to find what they are looking for. At the same time, they enhanced the experience, compelling users to discover new things that they might not have intentionally visited the site to find. From a functionality standpoint, we got exactly what we wanted and needed. Beyond that, the CMS they built the platform on is very easy to use and offers us the flexibility to easily change content to keep our site fresh on an ongoing basis. The Trademark team was extremely professional and on top of technology; they made the process fun and educational!

Trademark built our site in 2015.
I wanted a marketing tool that would take us into a new stage of lead generation. Trademark delivered exactly that. Our lead flow has skyrocketed as fast as our Google rankings.
My team can easily manage the content in house. Their hosting and support has been very solid. Ongoing changes have been reasonably priced and executed well.

They are consistent and interested in your success. Once their engineering team has learned your stack, you can't tell from inside to external resources. Work just gets done. I recommend them w/o reservations; start-up or well established firm, you are in great hands with the DualBoot team!

Priyanshi Verma's Review Sourced from Google
Unprofessional, Mentally Draining, and Disrespectful Work Culture
My overall experience with this company was extremely toxic. During my short tenure, I observed several deeply unprofessional practices that left a lasting negative impact on me:
• Salaries were often delayed, without prior communication or explanation.
• There were unexplained deductions in monthly salary, and any attempts to raise concerns were either ignored or dismissed by HR.
• The HR department was shockingly rude. I personally witnessed employees being humiliated or emotionally broken when they decided to resign — some even left in tears.
• No proper Full and Final Settlement (FNF) or professional offboarding process was followed. It’s like once you resign, you’re treated as if you never existed.
• Even after resignation, the company continued to send intimidating and threatening emails and begging for small amount of money like 20k, showing a complete lack of empathy — especially towards people who were already in a tough personal or financial situation.
If you’re considering joining, please rethink carefully. Make sure everything is documented in writing — verbal promises mean nothing here. A company’s real face shows not when you join, but when you try to leave. And unfortunately, this one shows zero professionalism, zero compassion, and zero respect for employees.

One of the worst organisation I have ever experienced . Exit process is worst moreover company doesn’t respond on your final f&f queries and literally one has to chase to get their full n final payment. Depending upon clients requirement organisation and their leaders push their employees and even salary is deducted if it is not billed as per clients need. Pathetic to be honest. Lala companies are doing better than this in country.

Here are some of the QA tests that US .NET development companies employ:
Unit testing: Examines the software’s individual components, including module behavior, code-level functions, and error handling
User acceptance testing: Simulates real-world usage, such as user interaction and how well the app integrates with business processes and workflows
Integration testing: Assesses how the different system components interact with each other, including how data flows and how third-party systems work together
Regression testing: Analyzes the stability and functionality of the app after a bug has been fixed
