Yes, there is, I was working at a company where a person was part of GrowthX cohort and it was considered to be a big thing by team mates.
But my other set of connections working in reputed agencies and large service sector companies do not even know GrowthX. They are all aware of folks like Digital Deepak and Neil Patel though.
GrowthX at the moment is known by a small set of people but this small set of people are high achievers.
Again, does this justify 80K pricing?
Only if your target companies are startups, then maybe it will get your resume noticed and one may even get first interview because of GrowthX tag.
