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
Tune, formerly HasOffers, is a Seattle-based partner marketing platform company that has provided affiliate tracking and performance marketing technology since 2009 — when it launched HasOffers as one of the first SaaS affiliate tracking platforms to serve the emerging performance marketing network market as an alternative to licensing expensive on-premise tracking software. The HasOffers platform became the foundation for hundreds of performance marketing networks, enabling entrepreneurs to launch professional affiliate operations without the prohibitive technology costs of building proprietary tracking infrastructure. The company rebranded to Tune in 2015 and expanded its platform to encompass mobile marketing measurement through the acquisition of MobileAppTracking (later TUNE Marketing Console), adding mobile app install attribution alongside its established web affiliate tracking capabilities.
