Constructor

Constructor is a San Francisco-based company that builds an AI-native product discovery platform for enterprise ecommerce. It was founded in 2015 by Eli Finkelshteyn and Dan McCormick, both former Shutterstock engineers, and runs as a remote-first business with staff spread across roughly 40 countries. Finkelshteyn serves as CEO.

The platform centers on a Commerce Reasoning Engine that personalizes search, autosuggest, browse, and recommendations using real-time clickstream and shopper-intent data, with additional modules for retail media, collections, quizzes, and AI shopping agents. Constructor optimizes results toward business metrics such as revenue rather than text-match relevance alone, and counts Sephora, Petco, Birkenstock, Bonobos, home24, and The Very Group among its customers. In 2026 it was named a Leader in the Gartner Magic Quadrant for Search and Product Discovery.

The company has raised more than $85 million to date. It closed a $55 million Series A led by Silversmith Capital Partners in 2021, followed by a $25 million Series B led by Sapphire Ventures in June 2024 that tripled its valuation to $550 million. Constructor employs roughly 400 people worldwide.
