Not summarised quotes, but what they literally said to us.

“Working with Jason has been going really well for me so far. He responds incredibly fast, always works everything out properly and in full, and is critical and realistic. Together with his developers he builds good-quality software quickly and for a normal investment, so it's no surprise we're pushing hard on growth. Highly recommended!”
Jeroen JansenFounder, NL Safety
“Very happy with the insights your consultancy delivered. Finally a clear, phased plan we can build on and make progress with.”
Roy WitmaarSales Manager, Daan Kromhout
“An absolute must when your organization is looking for an objective, critical, and knowledgeable perspective on the possibilities of AI and automation within your company, and how you can concretely get started with it. In the collaboration, I experienced many eye-openers, so I am very satisfied.”
William BremmersFounder & Director, LeanHR
“When I first started using it, I was genuinely surprised how good it was. The system we built together comes up with good ideas, works everything out thoroughly and well, and really saves us a huge amount of time. It was a strong start to a lot more expansion.”
Jon-Ivar SorensenOwner, Het Roode Koper
“Worked with Jason and Coen on a roadmap to make our company tech-first going forward. A really great sparring partner, and a strong combination of vision/energy with pragmatism and structure.”
Matthijs NoordhuisThe Music Company
“Things moved super fast with the guys at Stonewell, and within 3 weeks they built a solution that automated 80% of our certification process. Really great!”
Job KuiperOwner, Permaco

“Working with Stonewell is genuinely great. You're always incredibly fast, come up with good ideas, and what you build simply works really well. It saves me a huge amount of time, which we can put straight back into our customers, so I'm very happy with you.”
Patrick SmidtOwner, AlterWood
“Jason and Coen always respond incredibly fast, and solve anything that comes our way with software. It was a great collaboration, also on an entrepreneurial level. I'd definitely work with them again.”
Johan MarsOwner, MW Solutions
“Stonewell immediately thought along with us. They listened to what we needed and translated that into a clear plan.”
Guido SipOwner, Verwaard Bouwstoffen
“Jason always responded super fast, thought along with us well, and whatever challenges came up from the ERP side, they quickly and proactively found a good, fitting workaround. If only every IT company had a few more Jasons on staff.”
Kelly KlawerOperations Director, TLANT
“Working with Stonewell is very pleasant. They map out your wishes well, think along with you, and communicate honestly and quickly. I get the feeling they charge for what's actually needed, and if something occasionally runs over, they take that on themselves. You barely see that anywhere these days. Highly recommended!”
Max KelnerOwner, Max-Fit
“The feeling was good from the very first contact. You communicate clearly what I can expect and what I'll get, communicate super fast, and deliver a lot more value than what I actually pay for. You don't see that often with companies anymore.”
Bram KomenOwner, BKA Installatietechniek
“The system really works great! I can easily chat with the AI and come up with new collection ideas and improvements together with it. Really excellent! On top of that, communication is always fast and informal, so working with Jason is very pleasant.”
