Did I Pick the Wrong Industry for My B2B SaaS?

I'm a first-time entrepreneur delving into the Tech HR/Recruiting industry with a B2B SaaS aimed at automating screening calls using AI. After developing my MVP, I've been reaching out to recruiters in my LinkedIn network to enroll them in a pilot program. However, the response has been lukewarm so far.

I'm aware that I need to expand my outreach and refine my approach, but I'm starting to wonder if I've chosen an overly competitive or saturated market. Conversations with fellow entrepreneurs and insights from IndieHackers and Reddit DMs suggest that many companies, both big and small, are exploring similar solutions, and gaining customers in this space is challenging.

Now, I'm at a crossroads: should I persist in this direction or consider pivoting? Is the recruiting industry too crowded for a new player like me? I'm also curious about other industries that might be more welcoming for first-time B2B entrepreneurs. Any insights or advice would be greatly appreciated!
