AI agents are getting smarter—but more importantly, they’re getting better data.

Similarweb and Manus have announced a new integration that gives the Manus AI agent direct access to Similarweb’s web traffic and engagement data, a move aimed squarely at one of enterprise AI’s biggest pain points: unreliable or hallucinated insights.

Available now, the collaboration allows Manus customers to deploy autonomous agents for tasks such as building marketing plans, assessing competitive positioning, and analyzing growth opportunities—using market intelligence anchored in Similarweb’s digital data rather than guesswork.

Why data quality matters for AI agents

As AI shifts from chat-based assistants to agents that execute real business decisions, the risk profile changes. A hallucinated answer in a brainstorming session is one thing; a flawed market analysis driving budget or strategy is another entirely.

That’s the gap Similarweb and Manus are targeting.

“The kind of work Manus agents do—market analysis, growth planning—depends on trusted data,” said Omri Shtayer, VP of Data as a Service and AI at Similarweb. “Data is the fuel, AI is the engine, and agents are the aircraft. Manus has built a very high-performance jet. We help make it reliable.”

The integration is designed to ensure that when Manus agents analyze markets or competitors, they’re working from validated digital intelligence rather than scraped or inferred signals.

What Manus agents can now access

Through the integration, Manus AI customers can tap into Similarweb’s global digital intelligence platform, including:

• Monthly visits and unique visitors

• Traffic sources and digital marketing channels

• Competitive web performance benchmarks

Joint customers also gain deeper access tied to their Similarweb accounts, including advanced segmentation, geographic breakdowns, and data spanning SEO, ecommerce marketplaces, mobile apps, search, and GenAI brand visibility.

The integration runs through the Similarweb MCP Server, using the Model Context Protocol (MCP) to structure data in a way that’s optimized for AI applications—making it easier for agents to reason over complex datasets without distortion.

A fast-moving AI platform meets enterprise-grade data

The partnership arrives as Manus continues an aggressive growth trajectory. Less than nine months after launch, the company says it has surpassed $100 million in annual recurring revenue, claiming the title of the fastest startup to scale from zero to $100M.

Manus positions itself as an autonomous AI agent platform, designed to move beyond prompts and chats toward outcome-driven collaboration, where users delegate complex digital work end-to-end.

For that model to work in enterprise contexts, credibility matters.

“As AI agents take on decision-critical work, the authority of the underlying data becomes essential,” said Henry Yang, co-founder and CMO of Manus. “Similarweb provides a trusted view of digital markets that helps ground our agents’ outputs in reality, not speculation.”

Similarweb’s broader AI strategy comes into focus

The deal also highlights Similarweb’s own push into AI-native workflows. The company has been building purpose-driven agents internally, focused on sales, prospecting, and content marketing use cases where speed and accuracy directly affect revenue.

By integrating with Manus, Similarweb extends its data into a broader agent ecosystem—reaching users who may not yet be customers, while reinforcing its role as foundational infrastructure for AI-driven marketing decisions.

Notably, Similarweb is among the first technology partners Manus has integrated at this depth, joining Stripe for payments and Microsoft for Microsoft 365 access.

Setting expectations for agent-powered marketing

The collaboration reflects a larger shift in martech: AI agents are no longer novelty tools. They’re being asked to plan, analyze, and recommend—functions traditionally reserved for senior marketers and strategists.

That raises the bar for accuracy.

By pairing Manus’ general-purpose agent architecture with Similarweb’s market intelligence, the two companies are betting that the future of AI-powered marketing isn’t just faster insights, but defensible insights.

As Or Offer, CEO of Similarweb, put it: “Manus has been a pioneer in general AI agents. We’re proud to support that vision with data marketers can trust.”

For brands experimenting with autonomous AI in marketing, the message is clear: smart agents still need solid ground to stand on.
