Built by people who've lived the problem
Planster started with a spreadsheet.
Steve Clark was working at Kodiak Cakes when he built a forecasting spreadsheet to handle their inventory planning. It worked well enough that he started adapting it for other companies--first one, then five, then twenty.
After working with 30+ brands, a pattern became clear: everyone was struggling with the same problem. Inventory planning was either buried in spreadsheets that broke constantly, or locked behind enterprise software that cost more than most teams could justify and still didn't quite fit.
And we kept seeing the same outcome: brands with great products running out of cash because they had the wrong inventory at the wrong time. Too much money tied up in products that weren’t moving. Empty shelves on their best sellers. It wasn’t a forecasting problem — it was a cash problem dressed up as an operations problem.
The existing tools were either overpriced, under-featured, or limited to a single channel or industry. Nobody had built something that could flex across D2C and retail, handle multiple warehouses, and still be affordable for a growing brand.
So we built it.
Planster takes everything we learned from those 30+ implementations and puts it into software that works the way planning teams actually work. We built the tool we wished existed--one that handles the complexity of real inventory planning without the complexity of enterprise software.

Connect on LinkedInThe team
We're a Utah-based team of CPG operators who've spent years in the trenches of demand planning, operations, and product development. We know what it's like to stare down a spreadsheet at 2am trying to figure out whether you're about to stock out on your best seller. That's why we built Planster--so you don't have to.
How we work
Straightforward by default
Transparent pricing, honest capabilities, no surprises. We'd rather tell you what we can't do than overpromise and underdeliver.
Built to last
We're not chasing the next shiny feature. We focus on making the core product better--more reliable, more accurate, more useful--every day.
Partners, not vendors
We win when you scale. Planster does the work of a planning team — the forecasting, the reorder math, the overnight checks — while every decision stays with the people who own the outcome.
