We've been using highlight for our bootstrapped member management platform[1] and I gotta say I'm super impressed with the session replay feature, it's really helpful for understanding user behavior at a fraction of the price of competitors.
I remember wanting to use Heap's session replay only to release they want hundreds of dollars per _month_, my last bill with highlight was $2.38 I recall.
That's all to say that I'm glad Highlight is figuring out how to scale while still offering their features to the small players of the world.
