      Rebecca Larry's Review Sourced from Google

      Had an Interview here and the old wrinkly man who interviewed me was extremely rude and passive aggressive. The best time that came out of the interview was that I did not get this job, if I had I would have 10000% quit because of the hostile and aggressive environment. do not use this company unless you enjoy talking to rude old people.

      Tried to get one of my Pakistani artists studio time here but they are super selective about who they work with. We offered to do promo and pay for a few hours each week instead of booking their usual five hour minimum but extreme rules for a studio.

      Small Businesses Website Development Review from Kris Meyer

      Austin rebuilt our website from the ground up and helped turn Bespoke Tint & PPF into one of the top tint brands in Bellevue. The work started with a full redesign of our website, including branding, copywriting, conversion improvements, mobile optimization, and development. The new site immediately performed better and generated more leads after launch.After the website launch, we continued working together on SEO, AI search optimization, paid advertising support, analytics, A/B testing, and ongoing marketing strategy. He also helped improve our review visibility, local search presence, and overall positioning online.What started as a website project became an ongoing growth partnership focused on increasing traffic, leads, and customer acquisition.

      We needed a custom solution to parse various PDF formats, clean the extracted data using AI, and seamlessly store it in a database. A previous vendor failed to handle our document variety, but this team delivered flawlessly. They built exactly what we asked for—accurate parsing, intelligent data cleaning, and structured database storage. Highly recommend!

      Md. Mirajul Islam's Review Sourced from Google

      We were ranking well on Google but weren’t getting any clients from ChatGPT or other AI platforms. I reached out to them for help with AEO/SEO, and within a week of launching the changes, we started getting website traffic from ChatGPT. It has been about two months, and now we are also getting traffic from Grok and Gemini. Very thankful for the results.

      I highly recommend Hardeep at AdaptAI to any business owner looking to improve their operations and client experience. He took the time to understand how our business functions and helped implement solutions that simplified processes, improved efficiency, and reduced administrative workload.His attention to detail, responsiveness, and ability to understand our business needs allowed him to implement solutions that improved workflow, automation, and overall client experience. He was proactive throughout the entire project, communicated clearly, and consistently delivered on expectations.What stood out most was his ability to think beyond design and focus on creating systems that support long-term growth. If you’re looking for someone who is knowledgeable, reliable, and genuinely invested in helping your business succeed, I would highly recommend him.We’re grateful for his support and look forward to continuing to work with him as our business grows.
