"we doubled our revenue. In a nutshell, David automated and reorganized our tech stack."

David is the man! Has helped me so much with my business! Highly recommend taking advantage of this. thanks again my man!

Very helpful information would definitely recommend. I thought I knew a lot, but this reassured me that you can always learn something new and valuable.

I have worked with many web partners throughout my career and David IS the best. He is professional, proactive, and highly proficient. David is a true partner who makes your vision a reality and optimizes opportunity for sales and ROI.

Kudos to David for taking the time to chat with my about e-commerce platforms. I thought my knowledge was pretty decent from some blog posts, but getting his input and experience on my specific needs was invaluable. I'm grateful I chatted with him and hope we can work together in the future.

David is a professional, skilled, and creative web designer! He is very communicative via email or phone and has no issue meeting even tight deadlines. He built our website from scratch, and we get thousands of visit and dozens of sales each month because of our impressive site. Thank you, David!

David and I worked on a marketing team for a few years and I've seen him pull of countless technology miracles. David is a true tech-whisperer! He gets disparate technologies to communicate with each other -- even when the help docs and tech support people tell you it cannot be done -- David gets it done! I would be more than happy to work with David again.

Gizio has helped my business enormously and I am so grateful for their ongoing support. Experienced, smart and efficient, they take a lot off my plate and working with them is a pleasure. Since they redesigned and relaunched our website, our conversion rate is up almost 40% and our total revenue is up nearly as much. They've gone above and beyond, which I really appreciate.

Gizio is extremely talented at what they do. I have a very small business in Breckenridge Colorado and they were so gracious to take me on as a client. They rebuilt my website, helped me launch it and continue to help me grow my online store. I cannot thank them enough for believing and supporting small businesses. I highly recommend them. They are a fantastic team! Thank you so much for everything!

If you're looking to streamline the technology for your non-profit, David will get it done. He helped CPA-NA migrate years of data to a new CRM to better track our donor and member engagement, streamlining operations and saving dozens of hours of work every month. In less than 3 months, his systems directly contributed to our $52k fundraising success! David's collaborative approach and ability to explain complex concepts made the whole process smooth. Before David, our reporting and donor management was unruly. Now, we're achieving so much more in a fraction of the time. David's technical expertise and collaborative approach make him an invaluable asset to any team.

It has been an absolute pleasure working with David for a common client! We worked together in a small team of tech / marketing / eCommerce specialists and I cannot recommend working with David enough: His technical skills, knowledge and attention to detail is one thing - but his human qualities of being loyal, humble and supporting whenever you need him are invaluable and priceless! You can read a lot of "generic" recommendations on LinkedIn, but this comment from a co-worker describes it best: "David does not talk a lot - but whenever he does in a (virtual) conference, everyone immediately becomes silent." That is EXACTLY how it always was because David simply knows what he is talking about; in every single situation!

As the CEO of an 8 figure ecommerce brand, I had the pleasure of working with David Stack as our Tech Manager for over two years as we doubled our revenue. In a nutshell, David automated and reorganized our tech stack. I was particularly impressed by his expertise integrating various APIs and leveraging dozens of marketing SaaS tools - many of which were new to him. David's focus, determination, and ability to quickly pick up new tools helped us launch new marketing initiatives and drive revenue growth. David is an excellent communicator and team player who goes above and beyond to ensure that projects are completed. I highly recommend David for any role related to web technology or the integration of complex technical systems.
