I believe their point is that it doesn't look like the text was written by a native English speaker -- there are spelling and grammatical errors.

For a business, having spelling or grammatical errors is sometimes seen as an early indicator that the business is a scam. There are a variety of reasons for this and it's not necessarily fair.

The practical fix in your case, which I'd strongly recommend if you can, would be to find someone to review the text and fix all grammar, spelling, and formatting issues.

edit:

Also, some of your phrasings could be a turn-off because they hint at information instead of revealing it. (They "play coy.") This behavior is associated with people over-selling, exaggerating, or hiding things.

Examples include:

"Acoto has everything and for everyone."

"We have limited spots and many excited users so don't get left behind."

People have seen excited sentences like this so many times, we're immune to them. In fact they often have the opposite effect. Instead of using excited copy, it's better to focus on your great idea and users will get excited all by themselves.

Got your point. Though I used grammarly app to fix the grammar and it is showing perfectly fine still I would try to fix that. Also did you liked the idea and implementation? Thanks for helping me out.

I don't know. I suppose the simplest thing way to put it is that I don't know who is the target audience.

My feeling is that the people who could use this are, basically, people who are trying to get their first job as a software developer. They don't have connections in the industry, and they're focused on interview prep.

But is that person really going to sign up for what sounds like fairly expensive one-on-one tutoring sessions? Many people in the industry will answer questions for free, if you just send them an email.

On the other hand, is this service for pros who want long-term career growth? If so, you can charge more but you need a much stronger selling point (e.g. mentors who are known experts that people will sign up for your service to talk to.)

Anyway, in either case I'm outside of the target audience because I'm not interested in mentorship as a service, I prefer to build friendships, mentors, and role models in "real life."
