^ Definitely agree with Alexie Glover on this point. No, buyers are not going to g2.com and looking up the category or even individual products. They're building their product shortlist with LLM search and getting validation from peers through G2 and other forums (like Reddit).
I can't speak to starting from scratch with zero G2 presence and within an unclaimed category, but I have launched additional new categories on G2 at two different companies. My gut says yes, it is probably worth it to chase that early traction and leadership.
