SEO Review from Kealy McCormack
Epidemic Marketing knows a ton about SEO and helped get our website seen online! They were great at responding to our questions and continuing to hone in SEO on our website for years. Overall, the cost and wanting to move in house in order to have more control over the website is why we left but if anyone needs SEO help in Denver they are a great option!

SEO Review from Tim Cardona
Noah and his team have been so amazing for my automotive detailing business. I didn’t understand SEO at all but I knew I needed it to grow my business. When I first talked to Noah he wasn’t pushy on selling me anything. Just simply broke everything down for me to understand and made it work for me. He has helped my business stay competitive and on target with SEO and my website! I can’t thank Epidemic Marketing enough it has been over 2 years now I have been with them and I’m glad!!

CRO Review from Brian Hong
Noah is a wealth of information and someone I have the pleasure of working with. He provides extremely actionable insights with conversion rate optimization, as well as advanced SEO techniques that move the needle.We have worked on several CRO campaigns that helped turn more visitors into customers which made our dollar work harder for us and Paid Media campaigns. He’s a true pro and even better human.

Amazing and talented people. I’ve worked for both client and agency side and can can say their partnership is amazing. They truly care about ongoing operations and not just ending it at a project level. Highly recommend! Message me if you want specifics.
John Andesilich's Review Sourced from Google
I own a marketing firm in Troy MO and I recently met with Calvin at Sketch Development Services to discuss a software development project I have been thinking about pursuing. He was very nice, easy to speak to and even though his field is a bit out of my knowledge base, he was able to explain things in a way that made perfect sense. I look forward to working with him and his team in the future and recommend anyone looking for a software or app development company to give them a try.

Mobile App Development Review from Lee Tupper
Vention has delivered excellent design prototypes and accurate time estimates. The app is still in beta mode, and the partnership with [...] Vention will [continue] until the release of the next version. Vention is a reliable team that offers quality service. (Verified via email)

Staff Augmentation Review from Jon Wade
Vention’s efforts allowed the successful development of the product, resulting in new customers. They provided backend developers, business analysts, UI designers, and QA testers to develop our solution. Vention cultivated a seamless partnership through constant updates and a collaborative approach. Overall, their team’s well-rounded expertise was impressive.

Web Development Review from AJ Canty
We’ve been working with Vention for quite some time and consider them an extension of our team, rather than an offshore vendor. We needed solid mobile developers to work with our in-house engineers to build our Primer SDKs on both mobile platforms. This was not a trivial thing as it required a lot of cross-functional communication, but the Vention team was up to the challenge. They quickly adopted the best practices we follow at Primer and proved to be effective and proactive.

Sara Rathsack's Review Sourced from Google
I do not have enough good things to say about Dave! He is so kind and compassionate, and genuinely wants to help and watch you succeed with your business. He’s sharp, and does beautiful work. Great energy that always fires me up! Two big thumbs way up!!
Heidi Uzelac's Review Sourced from Google
I can't say enough great things about working with Dave. He helped me get my website up and running in no time, and what really impressed me was his ability to take my brand guide—just a simple PDF—and literally bring my vision to life. The attention to detail and care he put into every aspect of the site blew me away.One of the best things about working with Dave is having him on retainer. His skill level is incredible, and the value he provides is unmatched. I had a crazy request for a 24-hour turnaround on a sales page, and not only did he deliver, but he also did multiple revisions, getting it just right. Thanks to his fast work, I was able to make sales right away, directly impacting my business in a positive way.In the past, I’ve spent thousands on websites that ended up stagnant, but with Dave, it’s an ongoing, collaborative process. He’s always improving my site, making updates, and focusing on SEO so my business can keep growing. It’s clear he genuinely cares about his clients’ success, and I still can’t believe I was lucky enough to find him.If you’re considering working with him, don’t hesitate—Dave is the real deal, and you won’t regret it! Best investment you will make in your biz- hands down.
Jen Dreher's Review Sourced from Google
Where do I begin? I cannot say enough great things about Dave and his company. I chose Dave as my web developer when I first started my business. I have a luxury medical spa and I am VERY picky about my look and branding that I want to portray. Dave NAILED it on every level and together we were able to create my dream website. He gave me some options to go through and listed to every one of my thoughts and edits. Most recently there was an issue that needed to get resolved and he stopped everything else and gave my site the full attention that it needed and everything was perfect again in no time. I am so thankful I found Dave!

Ramez and his team designed a complete over hall of my website when I sold my marketing agency and went into consulting. It is sleek, professional and makes me look good. I'm very happy with the outcome.
Pediatric PT- Milk Matters PT's Review Sourced from Google
I'm beyond impressed with the expertise and ongoing support provided by Lightspace for my website. Their knowledge is exceptional, evident in the beautiful design and lightning-fast speed of the site. The ongoing support has been incredibly helpful, ensuring my website continues to exceed expectations. I'm thoroughly impressed, and everyone who visits the site is equally amazed! Kudos to the team for their outstanding work!"
S L K's Review Sourced from Google
I needed someone to move my website over from Wordpress to Shopify and communicated with several providers. Ramez from Lightspace Creative responded very quickly and was very polite and gave out a very positive vibe. His quote was a bit out of my budget but I decided to go with Ramez because he asked all the right questions and put me at ease. I was pleasantly surprised when at the end of the project, Ramez came back and told me he had completed the job in a fraction of the time. He was quick and efficient and in the end, completed the job well within my budget. My website looks great and works marvelously! After he was done with the project, I had some questions about the website, and Ramez took the time to answer them (and so politely too!). I've already recommended Lightspace Creative to several friends for their website needs.
