Eikona, a Tel Aviv–based generative AI startup focused on lifecycle marketing, has raised a $5 million seed round to bring a new reinforcement learning–powered approach to A/B testing and automated content optimization. The round was led by StageOne Ventures with participation from Crescendo Venture Partners, Wix Ventures, and Clarim Ventures, as well as several industry and academic angel investors.
The company’s platform applies Reinforcement Learning from Human Feedback to tailor marketing content to real user behavior, learning continuously from customer engagement. With this method, Eikona reports double and even triple digit lifts in lifecycle performance metrics, including sales, retention, and click activity. By integrating user feedback directly into model fine-tuning, the system adapts imagery, copy, video, and layouts across email, SMS, push notifications, and instant messages, while maintaining brand integrity and compliance requirements.
Eikona positions its approach as a solution to the growing pressure on marketers facing high customer acquisition costs and stagnant budgets. While social platforms long ago shifted to algorithmically personalized feeds, lifecycle marketing has lacked a comparable adaptive engine. Eikona’s technology is designed to fill that gap by creating an adaptive layer that evolves every customer touchpoint in real time.
The company states that its solution replaces traditional prompting and manual A/B testing with an automated, continuously learning system that can scale creative generation across customer segments. Eikona is already deployed across multiple industries where retention is strategically important, including retail, telecom, finance, insurance, healthcare, and travel.
Founded by CEO Nir Weingarten and CTO Omer Hacohen, Eikona operates as an Israeli-American venture developing enterprise-grade GenAI tools for marketing automation stacks. The company’s technology is built on top of foundation models and integrated directly into marketing communication channels to improve engagement and conversions.
KEY QUOTES:
“Creating engaging content was always the holy grail for digital marketing, and GenAI provides the blueprint to achieve it. This is what we have built at Eikona, a GenAI solution that creates amazing images and copy, while keeping product and brand intact, guided by performance instead of prompts.”
“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 to see, we are limited by what we can describe in the prompt, and we don’t scale. Eikona’s GenAI Reinforcement Learning solution replaces prompting and A/B testing with an intuitive, automated alternative that can truly unleash the potential of this incredible technology and completely reinvent how businesses speak to their audiences.”
Nir Weingarten, Co-founder and CEO, Eikona
“From our very first meeting, it was clear that the Eikona team is exceptional, and that we didn’t want to miss the opportunity to partner with them.”
“They quickly demonstrated impressive commercial execution combined with deep technical understanding of what this market truly needs. This is a rare opportunity to change how organizations approach marketing, making it genuinely personalized, and ultimately driving direct, measurable impact on business outcomes.”
Avi Shulman, Principal, StageOne Ventures
“A/B testing has barely changed in 20 years, it’s slow, manual, and often misses what really drives performance.”
“Eikona is changing that. The AI learns from performance and actually closes the creative loop, generating new ideas and assets that get smarter with every result. It’s the first time creativity and data truly work together at scale, and I’m excited to be part of what they’re building.”
