Proxima.ai provides AI-powered targeting for social media ads to help brands get better results from their paid campaigns on platforms like Facebook, Instagram, Snapchat, and TikTok. Its products use machine learning to automatically identify high-performing audience segments, optimize ad delivery, and continuously generate new audiences, all while protecting user privacy with anonymized data. The model includes subscription plans and performance-based pricing, aligning costs with the actual improvements in CPAs and return on ad spend (ROAS). Proxima addresses privacy changes (such as iOS 14) by offering automated targeting that expands reach without compromising data security or compliance. It differentiates itself through privacy-conscious automation, ongoing audience generation, and expert guidance to scale advertising efficiently across major social networks. The goal is to help brands scale their paid social campaigns profitably by reducing costs and increasing returns.
