Our EIN/tax ID number is 04-3582215. Your donations are fully tax-deductible to the extend allowable by law.
S3IDF has shown through its work among the poorer sections of society in Asia and elsewhere that its approach in designing innovative solutions is unparalleled. I recommend that the development community take advantage of the advisory services that S3IDF offers.
S3IDF is one of the pioneers in providing innovative and sustainable market solutions for energy poverty. S3IDF has been an active partner with ADB’s Energy for All for a number of years, and we value S3IDF both as partner and for the critical voice that has helped to refine our projects and point us towards priority areas where our support and intervention can help make a difference in the fight against poverty.
S3IDF is a special organization; highly experienced, capable, and dedicated staff carefully work at the intersection of technology, finance, cultures, and entrepreneurship in impoverished communities. Their work fully embodies their name.
