WooCommerce Review from Amanda Viviano
We hired Qolos to build our local florist shop's website on WordPress and WooCommerce, and we couldn't be happier with the results. From the start, they took the time to understand our business and created a site that's not only beautiful but easy for our customers to browse and shop.The WooCommerce setup was seamless, our online ordering works exactly the way we needed it to. But what really sets Qolos apart is their ongoing monthly maintenance. We never have to worry about updates, security, or technical issues because they stay on top of everything. Any time we've had a question or a small change request, they've been responsive and professional.As a small local business, it means a lot to work with a team that genuinely cares about keeping our site running smoothly. Qolos has been a true partner, not just a vendor. Highly recommend them to any local business looking for reliable web design and maintenance!

Web Development Review from Sanjay Singh
I kept getting negative reviews about my app for technical glitches, heating issues, functionality, loading time, crashing, and more bugs. So, I reached out to QOLOS after going through 2-3 renowned review platforms. I explained my app issue to the team, and they did tremendous work with their mobile testing solutions. Also, I wanted to build a website for my app. They created a feature-rich and seamless website.

Shopify Review from Sarah Nesheim
Working with QOLOS was the best decision I have made in regards to scaling my business. They are professional, so creative, they communicate every step of the way and their pricing is fair for the highest quality work. The designer of our logo and website did it well and I am so impressed and proud of the final product! the designer listened and knew exactly what I wanted which made the process so simple. Seriously could not recommend QOLOS more!

Software Development Review from Michael Levy
Flowty is a blockchain-based platform providing various transaction services around NFTs. K-Optional wears many hats in support of Flowty including Front End, Back End, business strategy, SEO and more.The K-Optional team has been incredible to work with. They are proactive, supportive, smart, thoughtful and, most importantly, fit seamlessly into our team and company culture. To put it succinctly, we tried to hire them full-time...and then tried to buy their company to acqui-hire them.Some of their strengths include: reliability, responsiveness and creativity. There are many groups out there that can perform some version of the work we are looking for. There are not many groups that are responsive at all hours of the day, deliver consistently and able to present data-backed business strategies.

Software Development Review from Jane Smarovozova
We collaborated with K-Optional to develop a custom inventory management dashboard tailored for real estate clients. We provided the creative vision and detailed designs, while their team focused on the software development, ensuring that every element was implemented perfectly. We worked hand-in-hand flawlessly, resulting in a sleek, user-friendly interface that not only looks great but functions seamlessly. The synergy between design and development allowed us to deliver a product that exceeded client expectations, combining aesthetics with powerful functionality.

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.

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.

Priyanshi Verma Review from Google

Priyanshi Verma's Review Sourced from Google
Unprofessional, Mentally Draining, and Disrespectful Work CultureMy 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.
