GenAI.Labs Reviews & Testimonials

AI Development Review from Alyssa Caridi
GenAI-Labs helped our agency build a centralized AI-powered platform covering influencer discovery, publicity monitoring, social listening, campaign management, and client reporting. Beforehand, these processes were spread across separate tools and required a lot of manual research and report preparation. Their team quickly understood our workflows and built a system that brings campaign data, creator information, media coverage, and reporting into one place. Reporting that used to take days or weeks now takes a fraction of that time, and our teams can manage far more campaigns without a matching rise in overhead.

AI Development Review from Brandon Cohen
GenAI-Labs was a valuable partner in helping us think through AI and automation opportunities for our organization. They brought a strong mix of strategic thinking and practical guidance, and helped us identify where intelligent systems could streamline workflows, reduce friction, and support future growth. What we appreciated most was that they kept the work grounded in real business value rather than making it feel theoretical. Their team was responsive, thoughtful, and easy to work with throughout the engagement.

Web Design Review from Dana Grobman
GenAI.Labs helped us bring the Clayla TLV website to life, and honestly, they just got us from the start. We needed a site that looked beautiful but also made it super easy for people to book events, workshops, or studio timeand they delivered exactly that. The booking flow is smooth, the design feels like us, and its taken a ton of manual work off our plate. They were responsive, creative, and just easy to work with the whole way through.

Logo Design Review from Lexi Piraino
Renee did a magical job on our logos for our new brand, Weekender Hotels as well as our new property, Placid Bay Hotel. Her friendliness and attention to detail and feedback made for a smooth process and timely project. We will absolutely be working with Renee and BrandMagic Agency for all of our properties in the future!
Mark Frisbie's Review Sourced from Google
As a small business, my online presence is all-important and crucial to the success of my business. Brandmagic addressed all of my branding needs above and beyond my expectations. They developed my logo design, my website, and assisted with my online profiles in a way that truly captures the essence of my business and what I want potential customers to know about me. As a result of the creative force behind Brandmagic, I gained new clients and established my business in my region. I can’t say enough good things about my experience with Brandmagic, and I am looking forward to using them again in the near future.
