Sprinkler Buddy Marketing
• Why Sprinkler Buddy ?
$52 Million market potential
1.1 Billion potential customers
100% yearly market growth
6 month payback to customer
Sprinkler Buddy at-a-glance
Large and Untapped Market
• 95% of the 1.1 billion farmers are from developing nations
• 60% of irrigation water wastage in these nations
The South Asian Farmer• Average yearly income is $795.56• 25% of yearly earnings are lost In water
costs
Current Solutions: Expensive/Un-automated• Prohibitively expensive for the average
farmer• Customer forced to make a choice• Do not adhere to standard guidelines
Sprinkler Buddy: The low cost, automated solution !
