Best Egg
From startup to fintech leader with $10 Billion in personal loans

Project summary
In 2014, we partnered with Marlette Funding to develop Best Egg, a more accessible and efficient platform for personal loans. The platform launched to great success, achieving $450 million in loans within just ten months and outpacing early competitors like Lending Club and Prosper. By 2020, Best Egg had transacted over $10 billion in personal loans, solidifying its position as a leader in the fintech space.
