Founder & Fractional Marketing Director

Diana Catrinoi-Cornea, Founder of Add-ON Partners

I don't just bring marketing expertise, I bring the perspective of someone who's lived inside a growing business.

CIM Chartered Marketer mark CIM Chartered Marketer 30 Under 30 award

After spending 10 years inside a growing business, I decided to use everything I learnt to help more founders, and more businesses.

During that time, I saw first-hand the pressure you're under as a business owner. Constant decisions to make, trade-offs, juggling so many plates at the same time.

Marketing very easily becomes 'the thing' nobody has time for.

Add-On Partners was born to change that, and become the partner your business needs to thrive.

Whether you're doing everything yourself or have a small, in-house team, we're here to help you make better decisions for your business.

AgileFleet Engineering www.agilefleet.co.uk

AgileFleet Engineering started with a big ambition to build a successful business, but we didn't know how to market it effectively. Diana and the team helped us bring our vision to life, giving us the direction and support needed to grow.

They now look after our ongoing marketing too, from social media and print materials to signage and everything in between, helping us present the business professionally and consistently across every touchpoint.

Mindful Track Therapy www.mindfultracktherapy.uk

Diana provided a thorough and genuinely insightful SEO audit that was clearly tailored to my business, not a one-size-fits-all report. She took the time to understand what I do and offered practical, thoughtful suggestions that felt relevant and actionable.

What really stood out was how proactive and attentive she was throughout the process. Professional, responsive, and genuinely invested in getting results, Diana is an absolute pleasure to work with and I would recommend her highly to anyone looking for effective, hands-on marketing support.
