About
sig.ai is an AI-powered marketing optimization and data engineering platform founded in 2018 and based in Seattle. The company was built on the premise that modern marketing performance requires more than rule-based automation — it requires machine learning that can model causality, adapt to changing market conditions, and optimize across the full stack of paid and organic channels. sig.ai applies reinforcement learning and incrementality measurement to help brands and agencies understand which marketing spend is actually driving incremental outcomes, not just correlated ones.\n\nsig.ai's platform spans several distinct capability areas: incrementality testing to isolate true causal lift from media investment, bid automation powered by reinforcement learning agents that optimize in real time against business outcomes, SEO tooling for organic search visibility, and AEO (Answer Engine Optimization) for brand visibility in AI-generated answers across LLMs like ChatGPT, Gemini, and Perplexity. Underpinning all of these is a data engineering layer that handles ingestion, transformation, and modeling of marketing and business data at scale — enabling the ML systems to operate on clean, unified signal.\n\nsig.ai serves marketing teams and growth organizations that need to move beyond last-click attribution and surface-level automation. By combining incrementality science, reinforcement learning, and AI visibility measurement in a single platform, sig.ai addresses the convergence of traditional performance marketing and the emerging discipline of AI presence optimization — a unified approach to marketing intelligence for a world where consumer discovery happens across both search engines and AI assistants.

About
Criteo is a Paris and New York-based commerce media company publicly traded on Nasdaq under the ticker CRTO that evolved from a retargeting advertising pioneer into a broad commerce media platform connecting retail media networks, brands, and publishers across the open internet. Founded in 2005, Criteo's original product — dynamic retargeting that served personalized product ads to shoppers who had visited a retailer's website — established the company as a leader in performance advertising for e-commerce and drove its 2013 Nasdaq IPO. The company subsequently transformed its platform in response to the deprecation of third-party cookies and the rise of retail media, positioning Criteo's first-party data graph and retailer partnerships as the foundation for a privacy-compliant, commerce-intent-driven advertising ecosystem that addresses post-cookie advertising performance challenges.
