Max Levchin Co-Founder & CEO at Affirm
5.0★
Mobile App Development Review from Max Levchin
We've partnered with HDWEBSOFT who have created our app using .NET. The feedback from our customers we've received has been overwhelmingly good. We had heard positive things about the idea even before we released the app, so it's encouraging to see those comments continue once it has been out. HDWEBSOFT was set up from the start. The design team was outstanding; they completed the job on schedule and within our allocated budget. They followed a well-defined procedure that was in place.

Keaton Lockhart Owner at BBGolf

Web Design Review from Keaton Lockhart
Friendly, flexible & fair price. I actually didnt end up finishing the project because my startup had some unanticipated delays. The guys at XpertApp went ahead and tabled my project and told me to reach out whenever in the future. True professionalism and customer oriented company.
Jande Sage Assistant Manager at Baranda Clothing
5.0★
eCommerce Development Review from Jande Sage
I had a friend who had one job and that was to stop me from availing any more services online. I had been a sucker for getting into the words of the operators that called me. Most would charm their way into making me get their services. The reason that Xperts App attracted me was that when I received my call rather than boasting about their services they rather guided me toward their website. It was as if they wished to convince me with their work and that is what hooked me.
Kevin Wasson Worker at Fireball
4.7★
Mobile App Development Review from Kevin Wasson
Xpertsapp is a great company that provides its customers with some amazing apps for their businesses. The apps and their features are highly advanced and perfectly suited for businesses. I cant thank them enough for the awesome work they have carried out so far. I am so happy with my app and am having a great experience since I started using it. Thanks once again!

Dennis Temko CEO at HyperCite
5.0★
Software Development Review from Dennis Temko
Dreamers was the only firm capable of building my ambitious vision for HyperCite. They transformed an unprecedented concept into a patented, production-grade legal technology platform designed for fact-checking. This included help in product strategy, and leading UX, algorithm development, AI, database and cloud architecture, frontend and backend engineering, scalability, observability, CI/CD, deployment, and ongoing maintenance. They delivered two California product versions and a dedicated Arizona implementation integrated directly with the appellate court, where HyperCite has operated for more than five years. Today, HyperCite not only automates hyperlinks between legal briefs and cited records; its AI fact-checking system compares claims against supporting evidence, flags contradictions and unsupported assertions, and takes judges and attorneys directly to the underlying source. The result is faster, clearer, and more reliable judicial review, delivered through close collaboration with HyperCite’s leadership and the Arizona court CIO.

Jax Warner's Review Sourced from Google
Do not recommend using this company at all. Their references seemed trustworthy, but the 20 month process with them has been abysmal at best.After engaging with Clavax to build a custom greenfield IOS app, we waited over 16 months AFTER our original due date for our "product" to be virtually unusable. Difficult to communicate with, over promise and under deliver on every aspect of project.We have had to spend more money with different companies to repair the broken code that they have put together and it continues to be a thorn in our side.They will bring excuse after excuse for why something does not work, their CEO will blame YOU, THE CLIENT, for the obstacles in project.We have tried to get a refund for breach of contract, inoperable product, corrupt files in repository, late deliveries, however, they refuse to acknowledge any of these issues.

Our D2C small business has used Vital to manage our digital marketing since 2020, and we've stayed with them because they continue to be able to test, iterate, build, and improve upon our account. I've worked with many agencies over the years but none that have given my company the amount of attention and driven the results that Vital has. Highly recommend.

Our non-profit has been working with Vital Design for a decade. They have been a true partner, helping us grow from a small online presence to an award-winning, globally accessed website. Vital has been, well, vital in improving our branding, aesthetics, navigation, and UX. We have greatly appreciated their quick response time, thoroughness, and dedication to producing work of the highest quality. Last but certainly not least, they are a pleasure to work with. I would give them ten stars if I could!

I was there at Perceptive Analytics for a while. During that time I had the opportunity to work with the CEO very closely. The man built the company from ground up all by himself. He once taught me some grammar in english, that's how much interest he took in me while I worked there. I happened to work with some of the most smartest and talented people from amazing institutions there. My advice if someone wants to work there is to be super smart or super hardworking.... Or at the very least learn to work with such kind to be like that. Thanks Chaitanya for everything.

Experience here instills values and a work ethic critical to making a mark in the service industry. Chaitanya's passion and attention to detail are qualities you can imbibe and nurture. All in all, the experience was fun and leaves you with memories you cherish for the rest of your life.

Srikar T's Review Sourced from Google
I have worked at Perceptive Analytics for approximately 10 months and my time at the company was awesome, to say the least.I have learnt a lot about sales and marketing which will be helpful for me going ahead. I have interacted with many clients and potential clients as well, and I got to learn a lot from these interactions.I also had a lot of freedom to experiment in my role, which was instrumental in enhancing my experience. The tasks I attended to were not limited to a specific domain but that only helped in increasing the potential of the job and though challenging, the role was equally rewarding for me.The work atmosphere is very good and the hours are very flexible.All the policies of the company are explained to the employees well in advance so as to avoid any confusion.The only problem that I've come across is that at times, you may have to work a little extra during peak season: like working for a while over the weekend or staying back for a while after working hours. On such occasions, work-life balance would take a hit. Work from home policy helps in these cases, though.I would definitely recommend working at Perceptive Analytics.
