I couldn’t be happier with my experience working with Devomech Solutions GmbH. We’ve just completed the POC phase of my project, and I am genuinely impressed by their exceptional professionalism, deep technical expertise, and commitment to making my vision a reality. Throughout the process, they’ve been proactive, communicative, and solutions-oriented, exactly what I needed to build confidence in moving forward. I’m now looking forward to transitioning into full production with Devomech Solutions GmbH by my side. I highly recommend them to anyone seeking a dedicated, knowledgeable, and supportive partner to bring their ideas to life!

Sketchy method of cold calling to get leads by claiming they talked to someone else at my org that they did not in fact talk to. Called on my personal cell phone. Would not do business with them if the engage this this type of misleading lead generation.

Sketchy people would be a polite way to put it.Kept sending advertisements to a general email box, I responded asking to unsubscribe, they started sending those advertisements to the email from which I responded.I wouldn't trust these people to do anything.

Mike Jones's Review Sourced from Google
I’ve worked with many agencies in my time as an entrepreneur, and started working with Br8kthru a year ago. It’s been the best agency experience I’ve had thus far. We started a business in March 2021 and finished the year with over $5MM in sales, thanks on part to their team taking on all of my digital marketing efforts - pushing me strategically and tactically to steadily build brand and drive acquisition. Thanks Br8kthru team!

Bill Svoboda's Review Sourced from Google
It was a pleasure working with Br8thru on our web project. They helped breathe life into our existing Hubspot website, and take it to the next level. I've worked with a few web companies in the past, but their Project Manager was the best to work with - very prompt email responses and pro-active in how they approached our build... they caught our vision for the project, then went to work since they're the professionals. Signing off on their work was easy at that point. Overall, it was an excellent experience and would highly recommend them.

I hired Br8kthru to help refine my company's branding. Jon and his team were insightful, creative and well organized, offering thoughtful and comprehensive feedback throughout the process. In addition to their skillfulness, they were a wonderful group of people, making the whole process a joy, start to finish.
