Company profile
researched Aug 2026The subject of this profile is Weave at the domain weave.in, a San Francisco-based company linked to founder Brian Ma and described internally as generating automated weekly professional introductions for users to facilitate networking connections.
None of the source documents retrieved for this profile describe that company. The available sources cover unrelated entities and topics that share the "Weave" name: getweave.com, a patient-communication and payments platform for healthcare practices; weaveos.com, a Y Combinator (Winter 2025) engineering-intelligence startup in San Francisco founded by Adam Cohen and Andrew Churchill that raised a $13.5M Series A in July 2026; and dictionary and encyclopedia entries for the common English word "weave." Because these are distinct organizations from weave.in, no rounds, metrics, events, or company-specific narrative details have been drawn from them.
As a result, this profile contains no externally sourced facts, and its completeness is limited to the internally held record.
