Sapna Agarwal ACA
Founder & Director, Stertha Advisory
Your tax adviser should understand your business — not just your returns
I founded Stertha Advisory because I saw too many founders and property developers getting generic advice from firms that treated them like filing deadlines. They deserved someone who understood what they were building and could structure it properly from the start.
As an ACA-qualified Chartered Accountant regulated by the ICAEW, I bring the technical rigour of the profession with the commercial pragmatism that growing businesses actually need. Every engagement starts with your goals — not a template.
I work directly with every client. No junior handoffs, no call centres. When you book a consultation, you speak with me.
