As of today, it’s virtually impossible for someone to explore all career opportunities (and offers).
Most people find new jobs by proactively reaching out to companies OR getting poached.
Unless you quit your current job, you never get the opportunity to broadcast that you are looking for new jobs.
It feels like there is an interesting opportunity for a company to be built around ‘free agents’ in the business world.
This company would essentially give you 1-3 months of salary/benefits, in exchange for a percentage of compensation increase.
