Web Development Review from Anonymous
Goji Labs designed and implemented a contact form plug-in on our WordPress site. They connected it to an external API for smooth data migration and ensured the design blended naturally with our existing site. The team made sure we were happy with the end result before wrapping up, which gave me confidence in their work.

Alyssa Brenke Marketing Manager at Cole Industrial, Inc.
4.8★
Web Design Review from Alyssa Brenke
Specifically, working with Ben was amazing! He was incredibly responsive and answered all my questions throughout the process of updating our website. Our original site was built roughly a decade ago (or longer) so we were in need of some streamlining and modernization. The team did just that and quickly! The first iteration was spot on for what we were looking for. Not to mention, they were able to launch quickly and without any interruption to our daily operations. Would 100% recommend [it]!

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.

Matt Hobbs Chief Product Officer at Canopy
5.0★
Software Development Review from Matt Hobbs
I am writing to recommend EffectiveSoft, a technology consulting company that has been providing services to Canopy for the last four years. During this time they have consistently demonstrated professionalism, expertise, and a strong commitment to meeting deadlines for our business outcomes.. Canopy’s mission is to improve the financial resilience of UK renters, and support the Agents and Landlords they rent from with our powerful referencing platform. EffectiveSoft has been a key partner, working with us to deliver our product and engineering roadmaps as we continue to grow and scale. Their skilled team of engineers has worked to understand our unique product needs and deliver quality platform increments following agile principles.One of the most impressive qualities of EffectiveSoft is their ability to respond flexibly to our changes in direction, and meet evolving delivery deadlines, overseen by Kirill Makarenko, our technical project manager. Kirill and the team’s strong work ethic, capability and diligence has been crucial in the successful execution of our projects. It is rare to come across an external development team that remains steadfast in its commitment to service standards and business continuity, and here EffectiveSoft have excelled. Based on our experience, I would highly recommend EffectiveSoft for any organisation seeking technology delivery services. Their dedication, responsiveness, and commitment to delivering results make them an invaluable partner.

Bighorn Web Solutions LLC Reviews & Testimonials
Jessica Grant Ecommerce Director at Sports Basement
5.0★
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.
