We help startups launch and grow

What we can do for you:

Hi! I’m Patrick, and I set up Rambunctious with the goal of making tech straightforward for growing businesses.

Through years of experience launching and scaling startups, we have developed expertise in rapid, iterative product development, building robust, scalable software systems, and setting up effective development teams.

We’re friendly, speedy and effective, with extensive experience building websites, mobile apps and digital services.

We aim to accommodate all budgets, so whatever your business, whatever your current tech needs, and whatever your stage of growth, we can help - just drop us a line!
