About 10 East
Portage Technologies Inc. runs under the brand 10 East, a private investment platform based in New York City. It helps members source and evaluate private-market deals. Members then invest alongside the firm itself. This is an institutional process of sourcing and diligence, aligned investment, and ongoing oversight after a deal closes.
The company works out of 10 East 53rd Street in New York. Michael Leffell is its founder and chairman, and Sam Klatt is its chief investment officer. Its members are typically self-directed investors already familiar with private markets. They include founders, partners, and portfolio managers from established investment firms, and prospective members must meet qualification thresholds before joining.

Why Investors Backed 10 East
Portage Technologies Inc. runs 10 East, a private investment platform based in New York City. It gives qualified members access to vetted private-market deals alongside its own capital. 10 East invests its own money alongside its members in every offering. Sam Klatt serves as the company's chief investment officer.
The problem it targets
People who want exposure to private markets typically rely on funding platforms, private wealth advisers, or investment clubs. 10 East's case is that none of those alternatives combine institutional due diligence, aligned economic interests, and efficient access to deals in a single platform. Putting its own capital into every deal it offers alongside its members closes that gap.
What the product does
10 East has a three-step process. First, it sources and vets new deals through its network. Second, it puts its own money into each offering alongside members, a practice called aligned investment. Third, its team handles ongoing oversight, including performance tracking and investor services. Membership is limited. Prospective members must meet qualification thresholds and complete an introductory appointment before they can invest alongside the firm.
Progress so far
Its members include founders, partners, and portfolio managers from established investment firms. Ted Seides, founder of Capital Allocators, is a 10 East member, advisor, investor, and shareholder. He says he was drawn to the firm because of its access to vetted private deals and its internal investment team.
