What the $15M enso round means for AI marketing startup funding
On October 1, 2026, Israeli startup enso announced a $15 million Series A led by MoreTech Ventures, with participation from NFX, Phenomen VC, and Gil Hirsch. The round brings enso’s total funding to $23 million, according to reporting by CTech. The company, founded in 2024, builds AI agent systems for marketing and sales.
For founders watching AI marketing startup funding, the round is less interesting as a number than as a signal. Investors are putting capital behind a specific claim: that marketing execution can move from manual campaigns to agent-driven experiments. Whether that claim holds beyond early adopters is still an open question.
enso calls its approach “Agentic Growth Hacking.” The capital will go toward expanding operations around that model, as businesses increasingly test whether AI tools can reach customers more efficiently than a traditional content or paid team.
Why marketing got harder to do by hand
The problem enso is aimed at is not hypothetical. Search algorithms, social feeds, and AI answer engines now collectively determine which businesses a user sees. Consumers and businesses increasingly turn to tools like ChatGPT, Claude, Perplexity, and Google AI Overviews to research products alongside traditional search and social platforms.
That creates a moving target. A growth tactic that works this quarter can lose effectiveness when a platform changes its recommendation system, ranking rules, or algorithm. User behavior shifts at the same time. For a small team, keeping up becomes a full-time job that competes with actually running the business.
This is the same pressure behind tools like Serpio’s trend-led content workflow, which starts from live signals rather than a fixed keyword list. If your organic strategy assumes last year’s search behavior, you are planning against yesterday’s internet.
How enso’s agents test tactics before scaling them
enso’s agents work in a specific pattern. First, they analyze how different platforms rank, recommend, and cite content. Then they test approaches through small-scale experiments and measure the results. When an approach proves effective, enso turns it into a repeatable growth mechanism for that customer. Tactics that stop working can be retested or abandoned.
The channel mix matters. enso’s systems operate across search and AI-answer visibility, sales outreach, online communities, newsletters, and social media. In AI search, for example, enso tracks which companies and sources get cited in answers to relevant questions, then measures whether changes in content and distribution affect a customer’s visibility.
This experimental structure is the useful part for a founder to borrow. You do not need an agent platform to run small tests before committing budget. But the principle is the same one behind trend-driven content planning: validate a signal cheaply, then double down on what actually produces results.
The limitation is equally clear. enso’s own published research includes unsuccessful experiments, and the company shares lessons from failures openly. That is honest, but it also means outcomes are not consistent. AI agents for marketing may not reliably drive measurable ROI, because platform algorithms change frequently and results are not guaranteed. The approach’s effectiveness beyond early adopters is unproven.
Where humans still sit in the loop
enso does not position agents as a replacement for marketers. For each customer, the company embeds an engineer and a marketer who connect the research to the customer’s existing sales and marketing operations, systems, and brand. The team builds a set of agents around those workflows and measures their performance against an established business and pipeline baseline.
Current customers named in the announcement include Papaya Global, MyHeritage, Papaya Gaming, Natural Intelligence, Winn AI, and Israel Canada.
Human oversight covers strategy, brand boundaries, and which playbooks get deployed. Agents handle ongoing monitoring, testing, and execution. Sensitive or irreversible actions remain under human control. That division is non-negotiable in the company’s framing: a person stays accountable for what the agents do.
For founders without a team to embed, the equivalent is to keep a human review step before anything goes live. A tool can draft and schedule, but brand boundaries and irreversible publishing decisions should stay with someone who owns the outcome.
What founders can take from enso’s approach
enso’s founder is Mickey Haslavsky, who previously co-founded RapidAPI. He coined the term “Agentic Growth Hacking” and is writing a book under the same title. The company employs 26 people, most based in Israel, and maintains open-source reference skills for AI agents alongside its published experiment research.
The founder background matters less than the operating pattern. Haslavsky’s own summary of the problem is direct: marketing teams can spend months building a strategy around channels that change before they see results. Agents make it possible to monitor multiple platforms continuously, test where opportunities are emerging, and act while those opportunities still matter. Then the team measures against a baseline and keeps a person accountable.
That sequence translates into a practical checklist for any small team:
- Track where your audience actually asks questions, including AI answer engines.
- Run small, cheap tests before committing budget to a channel.
- Keep only the tactics that prove repeatable.
- Hold a person responsible for strategy, brand boundaries, and irreversible actions.
If this round tells us anything about AI marketing startup funding, it is that investors are willing to bet on experimentation as a service. Whether agents can deliver consistent returns across companies and platforms remains unproven. The founders who benefit earliest will likely be the ones who treat the pattern seriously but keep the ownership of results in-house. If you want to see a simpler version of that workflow—trend signals, daily publishing, and a human review step—Serpio’s plans start with a small monthly article allowance and no credit card.
