The Israeli startup’s RLHF-driven system evolves every message, from imagery to microcopy, based on how individual users respond.
Eikona, a generative AI company aiming to reinvent how businesses communicate with their customers, has raised a $5 million Seed round led by StageOne Ventures with participation from Crescendo Venture Partners, Wix Ventures, Clarim Ventures, and several industry and academic angel investors.

Founded by Nir Weingarten and Omer Hacohen, Eikona applies Reinforcement Learning from Human Feedback (RLHF) to fine-tune generative models so marketing content continuously adapts to real-world customer behavior. The company describes its approach as a fundamental departure from the traditional workflow that has guided lifecycle marketing for decades.
While social media platforms long ago mastered personalized content feeds governed by user signals, lifecycle marketing - email, SMS, push notifications, and instant messaging - has remained largely static.
Eikona positions its technology as an “adaptation layer” between marketers and audiences. Its engine adjusts imagery, video, microcopy and layouts, while preserving brand, product and legal requirements, based on how individuals actually engage. The company reports that customers see double- and in some cases triple-digit improvements in sales, retention, and clicks.

“Creating engaging content was always the holy grail for digital marketing, and GenAI provides the blueprint to achieve it,” said co-founder and CEO Nir Weingarten. “Closing the feedback loop of user engagement enables us to break free of prompting. As human prompters, we’re biased toward what we think people want, we’re limited by what we can describe, and we don’t scale.”
