Digital Marketing Review from Jake Brennan
Storm Brain provided our e-commerce business significant results. We were really flattening out when it came to engagement and finding them was a serious game changer. They enhanced our SEO, helped us re-brand our product, drove sales through digital marketing campaigns and provided quality design for our site. If you're looking for a company that is easy to work with and incredibly professional / knowledgeable, look no further. We recommend them to the fullest, especially after being let down by so many other establishments. Storm Brain for the win!

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]!

Dustin Wheeler's Review Sourced from Google
it was such a pleasure working with App Founders and just how easy and professional they were. I quickly realized how the industry is full of thirsty, needy bots and scammers I’m trying to get your attention, but tons of unsolicited phone calls and texts. Dealing with these guys was a breath of fresh and definitely showed up in value above all the rest.

Nik Dunavant's Review Sourced from Google
I received what I believe was a scam acceptance email from this company. They stated that I got the job which I’m pretty sure I applied for on indeed. They made me download a third-party app called Skred and ended up blocking me because I didn’t wanna have to pay for equipment. Just be aware.

Karina Fowble's Review Sourced from Google
This is the third HubSpot agency we have worked with and by far the most outstanding. Krystina understood our problems from the beginning, Jory and Trevor solved what we thought was an unsolvable problem, and Samantha is an SEO rockstar and has been dedicated to making us successful. Charlotte continued to keep us on track, and Jordan worked to make the daunting task of paid advertising manageable, and we are seeing results. I highly recommend the Digitopia Team without any reservations.
