​Actualisation of business UK

Need help with business ideas.

I’m 27 have 4+ years sales experience and I’m earning around £50k.

I was in IT/Tech recruitment but found it difficult in the UK market so swapped over to SaaS sales.

I’ve always wanted to start my own business but don’t actually know the first thing about making a SaaS product and I’m not confident starting a recruitment agency as I was barely billing £60k doing a 180 role.

I want to sell something but e-commerce isn’t my cup of tea because I tried it before and hated the lack of human interaction.

I feel that I have great ideas but don’t know how to start getting things going – I’m a people person and can close multiple clients in a day in my SaaS sales role and I’m very good at it.

How do I find something to sell, can I approach businesses and offer to train their sales teams?

Any ideas or anyone had any success starting their own business?

Not looking for Tiktok trends of e-commerce course selling or SMMA as there’s lots of noise around the “easy cash” ideas that seem to be just people selling their courses.
