West Village side streets still feel like a secret, even when they’re lined with startups. Down at 69 Charlton Street, echo3D keeps a low profile—no signage, just a buzzer and a browser tab full of 3D assets. They build the invisible scaffolding that turns CAD files into interactive models; their tools power everything from AR product demos to digital twins of factory floors. If you’ve ever scrolled through a virtual catalog or spun a hologram on your phone, chances are you’ve touched their code without realizing it.

Around here, software companies tend to cluster near old warehouses and converted lofts. Charlton Street sits between Hudson and the river, a quiet strip where delivery bikes outnumber cabs and the Wi-Fi is strong enough to stream point clouds. The address—69 Charlton St New York, NY 10014—puts them a short walk from the High Line, though most of their traffic arrives via Slack rather than sneakers. Their stack handles cloud rendering, spatial anchoring, and cross-platform publishing; clients range from indie game studios to industrial manufacturers who need to preview machinery before it’s built.

Need to talk specifics? Give them a ring—no receptionist, just a direct line to the engineers who wrote the docs. For directions, pull up the map: one click and you’ll see the building sandwiched between a vintage record shop and a coffee roaster that smells like burnt sugar by noon. No need to announce yourself; the door’s always unlocked during business hours.
