Estimated value

What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.

Est. acquisition value

N/A

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A declining trend compresses what a buyer would pay.

    The plugin works like a charm, the support is swift. I had been playing around with a couple of review plugins for WP but none offered the kind of features this plugin does (rate in multiple categories, anonymous reviews etc.)
