Customer Support Review from Marie M. Harris
Although we have been struggling before, after expanding our influence into mountain wear and watches, it became evident that we needed some professional help. We were offering many new products, and making matters worse, we were present in different foreign markets, which mean many competitors to keep an eye on. After some consultations with the Vserve team, we had no doubts that they were the solution we had been looking for. Thanks to their proven MAP enforcement strategies, maintaining our market position is now easier. We always have accurate pricing information at our fingerprints. I must say, we are really impressed with Vserve.

Our company is grateful to have found a collaborative team in Vserve for our Product Information Management. Initially, we were unsure about the quality of product descriptions and their accessibility to our buyers. However, Vserve’s expertise in programming language and business best practices helped us to manage our complete product information and catalog pretty well. The conversion rate excelled our expectations, and our products shot up on Google rankings!

Ben Lee's Review Sourced from Google
My engagement with SLIDEFACTORY has been one of the best working experiences of my career. After launching multiple SaaS products as a product manager, I've worked with a fair number of technical teams ranging across a variety of tech stacks. SLIDEFACTORY has proven to be one of the most competent, agile, and customer obsessed teams I've worked with. After launching my own business and needing a detail oriented tech arm to execute, Mark and Tom were the people I needed to bring my vision to life. I owe them a lot and I look forward to the things we'll accomplish together.

I had a fantastic experience working with Mark at The Slide Factory. He was incredibly helpful throughout the entire process, asking thoughtful questions to ensure every detail was just right. His attention to detail and commitment to getting it perfect really stood out. The final product turned out beautifully, and I couldn’t be happier with the results. On top of that, Mark was kind, professional, and a pleasure to work with. Highly recommend his services!

Peter Kirwan's Review Sourced from Google
The Slide Factory is one of those companies you don't often have the privilege of working with. It's not just that they do high-quality work, listen to the client, meet your deadlines, and bring insights that may not have been on your radar. Those are important, of course. I think I value most that they are nice people to work with. They sincerely want you to succeed, and that can make all the difference. They are part of your team, and to me, that makes all the difference in the long run. They truly are a partner, not a company working for you.

As a client of Animus Digital, we could not have found a better company for our business and marketing needs. Their ability to see marketing from a holistic standpoint is unmatched, and yet be laser focused on the channels that produce the greatest returns. Jon and the Animus team are amazing to work with; this group is phenomenal at everything they do.

Jim Moss's Review Sourced from Google
Working with Jon Grogan and the team at Animus Digital has been a game changer for my business.
They didn’t just build a website they helped me clarify how I show up, how I communicate value, and how I engage the right clients. From day one, Jon has approached every conversation with insight, intentionality, and a deep understanding of both business and people.
Beyond the website, they’ve consulted with me on multiple marketing initiatives and recently built out a leadership assessment that has become a key tool in how I connect and serve new clients. It’s not just functional, it’s strategic, thoughtful, and aligned with the direction I’m taking my business.
What sets Animus apart is their ability to combine creativity with clarity. They don’t just make things look good, they make them work.
If you’re serious about growing your business and want a team that can think with you, not just for you, I highly recommend Jon and Animus Digital.

Integration testing: Assesses how the different system components interact with each other, including how data flows and how third-party systems work together
Regression testing: Analyzes the stability and functionality of the app after a bug has been fixed
