We are dedicated to finding the best companies for our collective future.

Karine and Sophie connected over their shared passion for impact and Venture Capital in San Francisco over six years ago. They have worked closely together at Single Family Office, Tamar Capital, investing with purpose across multiple geographies. Their combined experiences in direct and fund investments inspired them to create Tamar Ventures. They continue to lead with kindness and innovation—qualities that define their approach and vision.
