enso, an Israeli startup that builds AI agent systems for marketing and sales teams, has raised $15m in a Series A round led by MoreTech Ventures. CTech, the English-language technology site of Calcalist, reported the round on 1 October 2026.
Existing investors NFX, Phenomen VC and angel investor Gil Hirsch also took part. The new money brings enso's total funding to $23m. The company did not disclose its valuation.
enso was founded in 2024 and is led by chief executive and co-founder Mickey Haslavsky, who previously co-founded the API marketplace RapidAPI. It has 26 employees, most of them based in Israel, according to CTech.

What enso does
enso's product is built around an approach Haslavsky calls Agentic Growth Hacking, a term he coined and the title of a book he is writing. Its AI agents study how online platforms rank, recommend and cite content, then run small experiments and measure the results. Tactics that work can be turned into repeatable growth mechanisms, while those that fail can be tested again or dropped.
The agents work across several channels: visibility in search engines and in AI-generated answers, sales outreach, online communities, newsletters and social media. Marketers set the overall strategy and the boundaries of the brand, and actions that are sensitive or cannot be reversed stay under human control, CTech reported.
Haslavsky's argument is that marketing channels now shift faster than traditional planning cycles, so teams can spend months on a strategy only to find the channel has changed before it pays off. enso's pitch is to replace long planning with continuous testing run by software agents.
In practice, that means the agents keep running small tests across these channels, keep what produces results and feed it back into a playbook the marketing or sales team can reuse. People remain responsible for the brand and for decisions that carry risk, while the agents handle the repeated experimentation and measurement.
Customers and focus
enso names Papaya Global, MyHeritage, Papaya Gaming, Natural Intelligence, Winn AI and Israel Canada among its customers.
A report by Pomegra Startups, republished by af.net, said the company has moved its focus from small and medium-sized businesses to enterprise clients, and that it embeds engineers and marketers inside the organisations it works with. The same report said enso raised a $6m seed round in 2024 before this Series A.
Who invested and what the money is for
MoreTech Ventures led the Series A. NFX, Phenomen VC and Gil Hirsch, who had all backed the company before, joined the round. Other terms were not disclosed.
At $15m, the Series A is two and a half times the size of the $6m seed round that Pomegra Startups reported for 2024. NFX's return as an investor means enso's earliest backers have now funded it through two rounds in roughly two years.
enso said it will use the money to expand its Agentic Growth Hacking operations, as businesses rely more on AI tools to reach customers. It did not give a breakdown of how the money will be spent or set out hiring targets.
