Seth and Ela are prime examples of what early stage investors should be. They were instrumental in closing our seed round in under six weeks. We most appreciated their commitment to making new introductions and having conversations with each of our potential investors, expediting the fundraising process significantly.

Beyond the investment, Seth and Ela are still actively finding ways to help. Whether it’s advice on hiring or simply how to endure the emotional ups and downs of running a company. They’re an integral resource as we grow.
