Because spreadsheets suck. They just do.
I've been in your shoes.

I'm Adam Callinan, founder at Pentane, and I'm an eComm founder too.
BottleKeeper, my last company, grew to $8M in three years with zero employees or investors.
We then grew to tens of millions in revenue, went on Shark Tank, and were acquired by Wind Point Partners/RTIC Outdoors with 42 patents and only four employees.
We were lean, efficient, and very profitable—which wasn't an accident.
We relied on complex spreadsheets that were manual, hard to maintain, and led to costly mistakes. It worked, but it was a major struggle from startup through scale.
Pentane is the result of that experience, built for you.
