300 Million years ago, plants evolved to have lignin in their cell walls allowing them to grow tall and compete for more sunlight. Lignin gives trees their rigidity-defying the laws of gravity, and also their flexibility-allowing them to thrive in volatile conditions. We at Lignin Growth Partners think it is incredible that this simple evolution could have such an extreme impact on the trajectory of our world. It got us wondering what simple evolutions could change the trajectories of our country’s small businesses.

Often times, it is a single new partnership, deal, product innovation or distribution line that can affect the entire landscape of a company’s future. Identifying these growth opportunities and learning how to effectively execute and monetize these new ideas is what we do best.
