RNO1 Reviews & Testimonials
UI/UX Design Review from Neil Serebryany
I had the pleasure of working with RNO1 on a web transformation project in CalypsoAI and couldn't be happier. Right from the start, it was clear that they had a very skilled workforce, that had data architects as well as UX designers on board.They gave us a first implementation of your platform to work before your deadline and this demonstrates that they are conscious of time and the quality they want to offer. The look and feel design talents of RN01 are on par with the finest User Interface design and UX skills, moreover, the backend programming is also excellent.Most noticeable was their ability to fit into our working environment and improve the efficiency of our team while advancing the projects. Well done and organized they ensured the entire period was smooth and productive.As for web design and CMS development, I have no reservations in recommending RN01. They can really be considered as an innovation partner.
UI/UX Design Review from DANIEL HARMAN

Brand Strategy Review from Martin Alcala Rubi

Wow! I had Lindsey and Dave create my INCREDIBLE branding and website. They took my vision and goals and made it into a masterpiece. I am so thankful and I look forward to using it for the years to come! Thank you, Shameless Promotion!!
Artemio Palafox's Review Sourced from Google
We can't thank Dave and the Shameless Promotion team enough for developing our company's website. They were incredibly attentive to our needs, highly communicative, and easy to work with. We really appreciated their quality of work and level of efficiency in completing project tasks. Thank you, team, for the great work and we look forward to continue working with you.
Amy Marohn's Review Sourced from Google
Lindsey & her team at Shameless Promotion are a rare find! Their collective technical and marketing skillset is unparalleled; their ability to adapt and customize services based on clients' needs - unheard of in the mainstream marketplace; their level of professionalism, customer service and follow-through is exceptional. I am eternally blessed and grateful as a sole proprietor & middle-aged business owner to have some of the greatest brains in the marketing industry as a support. Highly recommend. I'd give them more stars if I could. THANK YOU!!
