Six Trees Capital LLC

Software companies shape the tools that keep cities running, from finance to logistics. In Midtown East, one firm operates quietly among the towers. Six Trees Capital LLC focuses on building platforms for investment workflows, data pipelines, and risk modeling—work that often stays behind the scenes but supports larger financial systems.

Offices here tend to cluster near transit hubs, and this one is no exception. You’ll find Six Trees Capital on the 9th floor of 445 Park Avenue, a building that sits between Grand Central and the East River. The address places it within walking distance of banks, law firms, and other tech teams that prefer a Midtown footprint over the usual downtown startup hubs.

Reaching out is simple enough. A call to 212-750-0000 connects you to the team during business hours. No need for appointments just to ask a question; the line usually picks up within a few rings. For those who prefer digital first, emails tend to get responses by the next business day.

Directions are straightforward if you’re already in the neighborhood. The map at this link will place you right at the entrance. No need to guess which door; the building’s lobby is clearly marked from the street.
