Amazing and talented people. I’ve worked for both client and agency side and can can say their partnership is amazing. They truly care about ongoing operations and not just ending it at a project level. Highly recommend! Message me if you want specifics.

John Andesilich's Review Sourced from Google
I own a marketing firm in Troy MO and I recently met with Calvin at Sketch Development Services to discuss a software development project I have been thinking about pursuing. He was very nice, easy to speak to and even though his field is a bit out of my knowledge base, he was able to explain things in a way that made perfect sense. I look forward to working with him and his team in the future and recommend anyone looking for a software or app development company to give them a try.

Vention’s efforts allowed the successful development of the product, resulting in new customers. They provided backend developers, business analysts, UI designers, and QA testers to develop our solution. Vention cultivated a seamless partnership through constant updates and a collaborative approach. Overall, their team’s well-rounded expertise was impressive.

Web Development Review from AJ Canty
We’ve been working with Vention for quite some time and consider them an extension of our team, rather than an offshore vendor. We needed solid mobile developers to work with our in-house engineers to build our Primer SDKs on both mobile platforms. This was not a trivial thing as it required a lot of cross-functional communication, but the Vention team was up to the challenge. They quickly adopted the best practices we follow at Primer and proved to be effective and proactive.

We needed a new website for our business and we knew it was time to update the design and make it more user friendly. Rootstrap helped us create our site with all of the latest technology and they were very flexible in terms of our requests. Award winning work! Kudos.

Web Development Review from Ori Goldman
When I was looking to build my MVP I spoke to about 10 shops. Little did I know that I would still be working with that same company over 5 years later. Rootstrap built our MVP and we have stuck with them ever since. Through multiple pivots, design changes, thousands of implemented features, we still feel lucky that we found them 5 years ago.

Shopify Plus eCommerce Review from Jessica Grant
Bighorn has been an exceptional partner to our organization here at Sports Basement. They supported us through multiple legal and regulatory accessibility matters with a steady, knowledgeable approach, translating complex requirements into clear, actionable guidance. Throughout these engagements, their team demonstrated a strong understanding of both the legal landscape and the practical realities of building and maintaining accessible digital experiences, which gave us confidence at every step.
What truly distinguishes them is that their work goes well beyond compliance. In addition to helping us identify and prioritize accessibility issues, they invested time in educating our teams on how to design and develop accessibility into our site from the start. Their recommendations are thoughtful, pragmatic, and focused on real user impact, enabling us to move from a reactive posture to a more proactive, sustainable accessibility practice.
Most importantly, they operate as true partners rather than transactional consultants. Their work is clearly driven by a genuine commitment to making the web usable by all, not simply meeting minimum standards or checking a box. We would strongly recommend them to any organization looking for a strategic accessibility partner who combines expertise, integrity, and a long-term perspective.

Software Development Review from Tiffany Asamoah
As a lead generation agency, we required custom software development to streamline our operations and enhance our capabilities. Bighorn Web Solutions far exceeded our highest expectations. Their team's hands-on, white-glove approach was evident from the start, and their level of competency truly set them apart. Working with a global team, they delivered tailored solutions that perfectly aligned with our business needs. Their responsiveness and attention to detail made the entire process smooth and efficient. Thanks to their expertise, weve gained not only a top-tier software solution but also a valuable long-term partner. We couldn't be more satisfied with the outcome and highly recommend Bighorn Web Solutions for their superior service and dedication.

Web Development Review from Sofia Juan
We recently had the pleasure of working with Small Projects Bureau Development on our new website for Show Kids, a company offering performing arts classes and after school programs for children in NYC. From start to finish, the experience was amazing.
The team at Small Projects Bureau Development truly understood our vision and was able to bring it to life in a way that exceeded our expectations. Their creativity, attention to detail, and technical expertise resulted in a beautifully designed, user-friendly website that perfectly reflects the essence of Show Kids. The website is not only visually appealing but also functional and easy to navigate, which is crucial for our audience of parents.
Throughout the process, they were communicative, responsive, and highly professional. They took the time to understand our specific needs and ensured that every element, from the layout to the content, was aligned with our goals. The final product showcases their commitment to quality and their deep understanding of web development.
We couldnt be happier with the outcome, and were excited to share our new online presence with our community in NYC. So much so that we are now working with Small Projects Bureau Development again to create a new website for our upcoming location in Barcelona, Spain.
If you're looking for a team that combines creativity with technical skill, we highly recommend Small Projects Bureau Development!
Thank you for helping us bring Show Kids to life online, both in NYC and soon in Barcelona!
