Key Takeaways
- enso raised a $15M Series A led by MoreTech Ventures, with NFX, Phenomen VC and Gil Hirsch participating.
- Total funding reaches $23M. The round follows a $6M seed from July 2024, and the valuation is undisclosed.
- The company pivoted from SMB agent subscriptions to embedding engineers and marketers inside enterprise customers.
Lead
enso, a Tel Aviv-area startup founded in 2024 by RapidAPI co-founder Mickey Haslavsky, announced a $15M Series A on October 1, 2026. MoreTech Ventures led the round. Existing backer NFX took part, joined by Phenomen VC and angel investor Gil Hirsch. The company did not disclose a valuation, revenue or customer count, so the size of the cheque is the main hard number available.
Total capital raised now stands at $23M. The company employs 26 people, most of them in Israel, which puts the round at roughly $577,000 of fresh capital per current employee, a ratio that implies a hiring push.
What Does enso Actually Sell?
enso sells AI agent systems for marketing and sales, delivered with human staff attached. Haslavsky calls the model "Agentic Growth Hacking": agents study how platforms rank, recommend and cite content, run small experiments, and convert the ones that work into repeatable channels.
The agents cover five areas: search and AI-answer visibility, sales outreach, community engagement, newsletters and social media. Marketers keep control of strategy and brand guidelines. The company places forward-deployed engineers and marketers inside customer organizations, a model closer to a consultancy with software than to a self-serve tool.
Customers named include Papaya Global, MyHeritage, Natural Intelligence, Winn AI, Papaya Gaming and Israel Canada. enso also publishes its experiment results, failures included, and maintains open-source tools.
How Has the Business Changed Since the Seed Round?
The business has moved from a low-priced SMB product to an enterprise services model. In July 2024, enso announced a $6M seed round led by NFX alongside a platform of more than 1,000 "guided" agents across 70 industries, priced at $29 to $79 per month per agent. Angels in that round included Yossi Matias, head of Google Research, and staff from OpenAI, Slack and Twitter.
The Series A pitch looks different. Instead of a catalog of cheap agents for small businesses, the company now describes custom go-to-market systems built inside larger organizations. The arithmetic of the two rounds leaves roughly $2M of capital between the $6M seed and the $23M total once the new $15M is counted, an amount the company has not itemized.
That shift is a familiar one for agent startups. Per-seat or per-agent subscriptions at under $80 a month are hard to scale without heavy churn control, and services-led delivery gives higher contract values. The tradeoff is margin: embedded staff cost more than software, and revenue growth depends on hiring.
Why Are Investors Backing AI-Driven Growth Hacking?
Investors are backing it because discovery is moving away from classic search. Buyers increasingly ask AI answer engines for vendor recommendations, and companies want to know how those systems choose what to cite. enso positions its agents as a way to test that question continuously rather than commit months to a channel strategy that may change before it pays off.
Haslavsky framed the pitch in those terms. "Marketing teams can spend months building a strategy around channels that change before they see results," he said, arguing that agents can monitor multiple platforms continuously and act while an opportunity still matters.
The skeptical reading is that the underlying platforms are opaque and shift often. Any growth mechanism an agent discovers on one answer engine can disappear after a model update, so enso's value depends on the pace of its research loop and not on any single finding. Without disclosed revenue or retention figures, the Series A reads as a bet on that loop and on the founder's track record at RapidAPI.
How Will the Money Be Used?
Haslavsky said the capital will go to three areas: expanding the research program to more platforms and more answer engines, growing the engineering team that builds the agent runtime and the workflows governing it, and growing the marketing team deployed into customers. All three imply headcount growth from the current 26.
Competitive Context
enso enters a crowded field. Established marketing platforms are adding agent features, and a wave of startups targets AI-search visibility with monitoring dashboards. enso's differentiator is execution: it runs experiments and operates channels rather than reporting scores. That puts it closer to agencies and growth consultancies than to analytics vendors, a group whose pricing and margins differ sharply from software.
Outlook
enso has $23M in total funding, a lead investor new to its cap table and a business model that has moved from self-serve SMB agents to embedded enterprise work. The next test is whether its experiments produce durable channels as answer engines change, and whether the services-heavy model can grow without margins thinning. Undisclosed valuation, revenue and customer retention leave those questions open until the company publishes more.
