Firstsignai Reviews
This is actually really impressive and tracks with a lot of what we've heard from customers.
We are satisfied with the ICP and synthetic interview bits. As for Nakxi, the product vision is shaping up nicely; it feels like we're getting closer to clarity on the direction.
This was great. I expected to see a bunch of high-level AI nonsense but you gave me a very clear POV on what we should go and test.
