PM - Skill enhancement/ Career growth

Hello! I am an entrepreneur who has 4+ years of relevant experience as a business analyst and of Product Manager. I am looking for a PM opportunity, as I could not scale my venture.

My experience was majorly focused in the growth domain with e-commerce and SaaS projects. I have completed a couple of PM courses to brush up my knowledge.

I have applied for 200+ companies in the past month, but did not hear back from anyone.

Kindly share any advice so I can upskill myself more effectively. Also please share some insights on how I can get referrals from my network.
