Director, Digital Experience Services

90% of all changes made to websites are based on opinion and are a waste of time and money because…

It is impossible to know 1000s of customers
Your opinion is deeply biased
You can’t rationalise the irrational

Regardless of the size of your business, the answer is to put data and experimentation at the heart of your development operations. 

We help you do that. 

We take the guesswork out of decision making and provide consultancy and training, systems and frameworks, and experimentation agency services to help you reach your full growth potential.

Jaimie

Here’s a recap of our milestones at Jaimie:

October 2023: We launched the Jaimie prototype, built in just two weeks. It attracted 150 users within the first five days! Our users had one main request: GA4 and Hotjar data integration.

February 2024: We launched our MVP, Jaimie 1.0, and acquired our first five paying customers within a week! 🚀 However, Jaimie took 45 minutes to generate one report, costing us €10 per report—a very expensive process.

August 2024: We relaunched Jaimie with AI agents and secured a fantastic partnership with SheroCommerce.

October 2024: We developed a proprietary CRO formula that helped the LLM focus on the most relevant e-commerce audiences and identify low-hanging fruit for optimization. We also reduced the time-to-audit to just six minutes, bringing the cost down to €1. 🚀
