Need Advice: Should I Pivot My SaaS?

Hey everyone, I'm a first-time entrepreneur who launched a SaaS called Hiringkit.co a few months ago. It's designed to assist recruiters by using an AI chatbot for candidate screenings. However, post-beta, traction has been low, and feedback, though positive about the concept, hasn't translated into usage.

Reflecting on this, and the market landscape, I'm considering pivoting from a chat-based tool to asynchronous video interviews. The new concept would allow candidates to engage more personally by seeing introductory videos from recruiters and responding with their own. This seems like a richer, more interactive approach.

There are similar tools in the market, like Hireflix, Spark Hire, VidCruiter etc, but I'm wondering if there's still room for innovation.

Could use your insights on:

Is this pivot worth exploring further?
Any tips on validating this new idea effectively?
Strategies for marketing and pinpointing the right audience for this tool?

Appreciate any feedback or suggestions!
