About us

The future of finance support providing expert, embedded, and effortlessly scalable finance department solutions

I’m Siân, founder of Superstar FD. After qualifying with ACCA in 2007, I spent many years running in house finance departments before launching my own business in 2024. What began as providing fractional CFO support quickly evolved, realising that clients needed more than strategic advice, they needed the capability of a full finance department. So I built a team and created a service that acts as a seamless extension of your business. We’re not just outsourced support, we’re your finance department.

When I’m not helping clients make sense of their numbers, you’ll find me outdoors in Surrey, muddy boots and all. I dabble in gardening, adore animals (I even used to be a gerbil rescue volunteer), and believe that staying grounded and curious makes me better at what I do.
