Israeli startup Enso has raised a US$15 million Series A round to advance its AI agent systems for marketing and sales. The investment was led by MoreTech Ventures, with participation from existing investor NFX, Phenomen VC, and angel investor Gil Hirsch. The round brings the company's total funding to US$23 million and will support expansion of what enso calls Agentic Growth Hacking.
A Shifting Marketing Environment
Companies are reaching customers amid rapid changes in search algorithms, social media feeds, and AI answer engines. Many buyers now use tools such as ChatGPT, Claude, Perplexity, and Google AI Overviews rather than relying solely on traditional search engines. This shift creates a moving target for marketers, because strategies that work today can lose effectiveness when platforms update their recommendation systems and user behavior evolves.
How the Agentic Growth Hacking Model Works
enso's AI agents analyze how different platforms rank, recommend, and cite content, then test new approaches through small-scale experiments. When a tactic proves effective, the company turns it into a repeatable growth mechanism for a customer. For each engagement, enso embeds an engineer and a marketer to connect research insights with existing sales and marketing operations, systems, and brand workflows.
The systems operate across search and AI answer visibility, sales outreach, online communities, newsletters, and social media. Marketers retain control over strategy, brand boundaries, and approved playbooks, while agents handle ongoing monitoring, testing, and execution. Sensitive or irreversible actions remain under human oversight, and performance is measured against an established business and pipeline baseline.
Haslavsky said marketing teams can spend months building a strategy around channels that change before they see results. He added that AI agents make it possible to monitor multiple platforms continuously, test emerging opportunities, and act while those opportunities still matter. The company embeds personnel with customers, builds systems around existing operations, and keeps a person accountable for what the agents do.
Early Traction and Customer Base
enso currently works with enterprises and startups including Papaya Global, MyHeritage, Papaya Gaming, Natural Intelligence, and Winn AI. The company was founded in 2024 by CEO Mickey Haslavsky, who previously co-founded RapidAPI and coined the term Agentic Growth Hacking. It employs 26 people, most of them based in Israel, and publishes research on its experiments, including unsuccessful ones and the lessons learned from them.
enso also maintains open-source reference skills for AI agents and has published studies showing the system's early impact. A LinkedIn distribution agent produced a 143x median reach lift across 24 posts, while a Reddit agent earned 270 karma across 11 subreddits and generated 28 inbound sales calls in one week. Proven playbooks are reused across customers, and tactics that stop working are retested or abandoned.
Investor Confidence
MoreTech Ventures co-founder and general partner Zack Keinan said marketing channels are changing faster than teams can adapt, and the newest channels have no established playbook. He described enso's method as treating distribution as a research problem and turning findings into growth for each customer. Keinan added that the firm believes enso is defining a category and is proud to lead the round.
enso's Series A arrives as paid acquisition becomes more expensive, inbound reach declines, and AI answer engines increasingly sit between buyers and vendors. The company is betting that platform playbooks are discoverable, that AI agents can find them faster than human teams, and that customers will pay for accountability over results. Its expansion plan will test whether an engagement model built around embedded engineers and marketers can scale with software-like efficiency.
