Constructor is an AI-native product discovery and search platform built specifically for enterprise ecommerce. Founded in 2015 by Eli Finkelshteyn and Dan McCormick and headquartered in San Francisco, the company replaces traditional keyword search with a reasoning engine that interprets shopper behavior, context, and intent to deliver more relevant results and recommendations across the buying journey.
The platform combines neural ranking, browse and category personalization, autosuggest, recommendations, collections, and quizzes into a single product discovery surface. Constructor optimizes directly against business metrics such as revenue per visitor and conversion rate rather than purely against click-through, and uses behavioral signals from millions of shopper sessions to continuously retrain its models. Major retailers including Sephora, Under Armour, Petco, Birkenstock, and Target Australia run Constructor in production.
Constructor raised a $55 million Series A led by Silversmith Capital Partners in 2021 and a $25 million Series B led by Sapphire Ventures in 2024 that valued the company at $550 million. The company has reported doubling revenue for multiple consecutive years and shared milestones from a record fiscal year 2024 that emphasized large enterprise wins and category expansion.
Constructor competes with Algolia, Bloomreach, Coveo, and Lucidworks. Its differentiation rests on optimizing search and browse for conversion rather than relevance alone and offering deep behavioral personalization tuned to large catalogs and high-traffic ecommerce sites.
