27 years in digital. 17 years making data useful for firms.

I'm Mark Barrett, and Data Dive is my data science, automation and analytics consultancy. I help organisations get their data in order, automate the manual work, and build the models, tools and teams that save time and generate revenue.

What I do

Most firms know AI could help; few know where to start or how to make it stick. I combine data science, automation and web development to put AI to work on real problems, and help your team adopt it with confidence.

AI strategy that's realistic
Where AI will pay off in your business, and where it won't. I help leaders set priorities, separate hype from value, and build a plan the business can actually deliver.
Finding the right AI use cases
Workshops and hackdays that surface your best opportunities, then rank them by value and effort so you start with quick wins.
Automating the manual work
Pipelines and tools that remove slow, error-prone tasks entirely, built so your team can keep running them.
AI built into your products and tools
Web apps with AI inside them, from assistants that draft a first version to platforms that find and rank information automatically.
Helping your team adopt AI
Coaching, hiring and building data and AI capability in-house, so the change lasts after I've gone.
Bringing energy to your teams
I love meeting people, understanding their challenges, and building high-performing teams that deliver great work. I bring energy, clarity and momentum, helping teams lean into innovation and become confident problem-solvers.

Three ways to work together

Your organisation, your people, your priorities. I work alongside your teams, calmly, focused on outcomes, so we build momentum quickly.
