Climate control software for small vertical farms
Small vertical farms lose crops to temperature swings because industrial control systems are priced for giant facilities.
Rootcell gives them a simple product that fixes this end to end, priced for small teams and live within a day of signing up.
Small and mid-sized organisations in our home market first.
Bottom-up: ~40k target customers at ~$1,500 a year.
What people use today
Spreadsheets and enterprise suites that are too heavy for this segment.
Why this team wins
Founders lived this problem for years and already have the first customers lined up.
Wei spent years on the customer side of this problem; Arjun built the technical core at a previous company.
