About Knowde Chemical companies are the hidden innovators behind the end-products we rely on every day. Chemistry is used to make every physical good on earth, including the products we love from Tesla, Glossier, Apple, Nike, 3M and J&amp;J. And yet, the largest and most impactful industry in the world is still doing business the same way it did 100 years ago. Knowde is building the first digital marketplace for the $5 trillion chemical industry. Chemical companies use Knowde to market and sell their products online for the first time ever.
