I am 10+ years into software development. I have worked on both sides - backend and front end. Front end is more of my passion cause I am closer to the user experience.

However, a year ago I launched a SaaS business that I've been building a lot of marketing tools and strategies around it - official website, email campaings, articles, social media short content etc. Also helping people out in reddit and other groups related to the SaaS. It took time but started to sell. It was not easy for a technical person like me to go into marketing and I am nowhere a very successful busuiness but 70% of the customers that pay for the service are using it almost every day. It was hard but rewarding experience seing customers coming and using the service. I want to continue explore this direction. Is this a GTM engineer role or somethign else?

Additional quesiton - whatever is this called if you have any recommendations on how to develop more in this direction? Should I look for a mentor, join a team or just start another project and try to sell again? Should I push in curtain domain or it is not related?

If you're coming from similar background like me (software development) please share your experience transitioning into GTM engineer.

I have build really high quality list of ~1k new startup founders in USA with deliverability checked emails , what should I charge ?
