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 !
