Your onboarding is broken and users are dropping off.

Your analytics are a mess and you can’t trust the numbers.

You have ideas, but no technical resources available to implement them.

I can help you tackle these problems head-on.

What I do

Build
Transform concepts into user-friendly websites, web apps and landing pages using tools like Webflow or frameworks like Ruby on Rails and BridgetownRB.
Market
Craft strategies and tactics to attract the right users, based on your company's unique objectives, strengths and opportunities.
Optimise
Implement analytics systems and use data intelligently to make impactful changes that drive compounding growth.

How I work

I generally work with early-stage software or tech-enabled startups. My clients face a range of product and growth-related challenges, and benefit from someone who can wear multiple hats - strategist, analyst, and developer.

Whether it's developing a growth strategy, integrating a new analytics tool, or optimising an onboarding flow, my approach is hands-on, informed by data, and focused on delivering measurable results.

I'm David Turnbull, the founder of Stirred. I have over a decade of experience in marketing, data analytics and web development, and grew an e-commerce business to a successful acquisition.

While much of my time is now spent building my own products, I take on a handful of consulting engagements when the project is interesting and a good fit.
