SapientPro Reviews & Testimonials

Software Development Review from Slava Berkovich
SapientPro consistently delivers high-quality work that aligns with project requirements. The team demonstrates strong expertise in Angular, TypeScript, and JavaScript. Their project management and communication practices are highly effective, with weekly client meetings held to provide updates on progress and ensure alignment.

Software Development Review from Jeremy Ott
This team was extremely responsive from the start. They pulled together a comprehensive quote for my MVP and have delivered on all of the requirements. The daily updates from the product/project manager are extremely helpful and it’s clear that the team cares about the quality of work they deliver. The engineers working on the product are always willing to make recommendations and go above and beyond to make the experience and underlying infrastructure that much better.

eCommerce Development Review from Luc Vlekken
We've had the pleasure of working closely with this development team on several projects, and the experience has been consistently excellent. Not only are they highly skilled developers, but they also think along with us both from a technical and a product/customer perspective. Their proactive attitude, reliability, and ability to translate complex requirements into elegant solutions make them a true partner rather than just a supplier. Highly recommended.

Kamlyn Spivey's Review Sourced from Google
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.
Haile Elizondo's Review Sourced from Google
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!
Jillian Krenk's Review Sourced from Google
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.
