I'm interested to hear more about your experience building data warehouse related products, and perhaps learnings you've had along the way. I guess selling to PE wasn't the initial goal, but I'd imagine your product is very well suited to the Redshift space.
I've been working on Snowflake related products, and their adoption speaks to a world of new problems being created, similar to your product with Redshift. I suppose the risk is being squashed by Snowflake building the feature, or businesses migrating to something new (perhaps Redshift products have suffered because of Snowflake)
Basically, what do the battle scars look like :D
