Our development portfolio

Best Egg

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.

I have been very impressed by their ability to adjust and execute quickly. It’s shocking, really.

Solar City

Common Assets, a pioneering financial services startup, aimed to democratize renewable energy investments in 2015. Their mission was to open up investment opportunities in solar energy to a broader range of private investors through an innovative online platform. To achieve this, they required a robust and user-friendly interface capable of streamlining the investment process. Common Assets turned to Kellton Europe (formerly Tivix) to bring their innovative concept to fruition.

I’ve found their unique combination of hard-core engineering skills and solid business acumen to be a phenomenal asset.
