Hi there,
I’m DennisErrikson.
Complex systems
experienced simply.
Strategy, design and engineering under one roof, from first idea to shipped product.
Recognised by
Expertise
one builder, four disciplines.
Systems thinking from physics and data processing, applied to products, AI, growth and brand.
Product development
Dennis has shipped products people use, most notably OneCareer App, live on the App Store and Google Play, and led product development at mobile-health startup MOBicure. He works from user research through launch, with a bias for products that solve access problems.
AI & data for business
Dennis applies AI and data analysis to marketing and business decisions. He is the builder behind Angel, the AI embedded across his products, and Angel Data Builder, a standalone research analyst that cites every source and returns exportable datasets. His foundation in Industrial Physics and Data Processing keeps the work rigorous.
Growth strategy & digital marketing
Dennis designs growth systems end to end: positioning, acquisition, conversion and retention. He has run growth for internet services in the US, consulted across the UK and UAE, and treats every channel as an experiment with a number attached.
Brand & design
Before he was a strategist, Dennis was a designer, and it shows. He led the design team at Career Masterclass in the UK, built health-communication campaigns for the Private Sector Health Alliance of Nigeria, and approaches brand identity as the visible edge of business strategy.
