Pump.co is a platform designed to help startups reduce their AWS (Amazon Web Services) costs through a combination of group buying and artificial intelligence. It targets startups with AWS expenses ranging from $1,000 to $100,000 per month, offering savings of over 60% on their AWS bills. The service automates the savings process, requiring minimal engineering effort from the user. Pump.co's AI algorithms manage the savings automatically, and the platform maintains security by only needing billing level permissions, without accessing the users' actual AWS accounts.
