A must-follow checklist for small businesses looking to connect with powerhouse companies like Wal-Mart. Tom Szaky didn’t even try to get his product–a worm excrement fertilizer packed in a recycled bottle–into small retailers when he started TerraCycle six years ago. Instead, he reached as high as he could: Wal-Mart. “If I want to be big and do it quickly, the best way … is to work with the world’s biggest companies,” he says. “They can accelerate your cycle much more quickly than any other company can.” The Trenton, N.J.-based company’s first big partnership with Wal-Mart in Canada was just the start of what has become a $14 million business. TerraCycle now gathers unrecyclable trash and converts it into products and packaging for such big brands as Kraft, Pepsi and Mars. Last year, corporate partners spent $45 million on TerraCycle-related marketing–far more than Szaky could have ever done alone.
