Used by teams at
SimilarwebProspecting companies by their online activity, traffic and technology. A fit for teams that sell on digital behavior.
Similarweb is a digital-intelligence company, and Sales Intelligence applies its traffic and technology data to B2B selling. An AI Prospecting Agent turns a plain-language prompt into a list of companies and contacts, layered with traffic spikes, tech-stack changes and intent.
Learning which companies fit from your own won and lost deals, then ranking the whole market with the reason on each account.
Ocean is contextual intelligence for go-to-market. It reads what every company actually does from its own website, learns what good looks like from your closed-won and closed-lost deals, and ranks your whole market against it, with the reason behind each score. The ranked accounts arrive in your CRM, your rep queue or your AI agents.
What buyers weigh, grouped by the job each part does. A light blue background marks the stronger side.
| Topic | Ocean | Similarweb |
|---|---|---|
| Finding the right accounts | ||
| Lookalikes | Ocean is stronger here. Core of the product. Segments and models learned from your won and lost CRM deals. | The AI Prospecting Agent turns a prompt into a company list, and you can chat to narrow it or apply filters. Its pages don’t describe finding lookalikes from your customer list. |
| Learns your ICP from won and lost deals | Ocean is stronger here. Learned automatically from your won and lost deals. | Lead scoring uses traffic, engagement and intent signals, and you refine an ICP with 100+ filters. It doesn’t describe learning fit from your CRM deals. |
| The reason behind each account | Ocean is stronger here. Segment, score, tier and matched signals on every account and every export. | Signals sit on each account: traffic spikes, tech changes and intent topics. They show what changed, not why the company fits your business. |
| Market size and segments | Ocean is stronger here. Segments your whole market and shows win rate, deal size and cycle time for each segment. | Territory planning defines a total addressable market from a database of 21M+ online businesses, with 100+ filters. |
| Contacts and data | ||
| Website traffic and engagement | Doesn’t measure website traffic. Reads what each company does from its own website. | Similarweb is stronger here. Its core strength: traffic and engagement measured from panel, first-party and public data, refreshed weekly for traffic and technology. |
| Contacts | Verified emails and direct phones from a waterfall across 16+ data sources. Charged only when a contact is found, and exports are free. | Verified business emails and direct dials where available, bought with data credits. Its pages quote 100M+, 470M and 500M contacts in different places. |
| Buying signals | Up-to-date signals built in-house from each company’s own teams, leaders, hiring and website. | Traffic changes, technology changes, press coverage and intent, with custom intent topics on Business (2) and Enterprise (10). Intent and news update daily. |
| Workflow and pricing | ||
| CRM sync | Two-way with HubSpot, Salesforce, Pipedrive and Attio. Reads your deals to learn, then writes scores, segments and signals back. | CRM integration starts on the Business plan, with a HubSpot marketplace app. Individual exports to CSV. |
| AI agents and MCP | MCP server, public API and a chat agent on the same data and lookalike engine. | Three AI agents (prospecting, outreach, meeting prep), plus API and MCP access from the Business plan. |
| Security and company scale | SOC 2 Type II and GDPR, per Ocean’s own site. | SOC 2 Type 2, SOC 3 and ISO 27001, with a public Trust Center, a security whitepaper and SSO on Enterprise. |
| Pricing | Two ways to buy: a flat-rate plan with credits included, or a custom plan built around your deals and credit volume. | Individual is $99 a month billed annually, or $129 monthly, for 1 user and 1,000 credits. Business and Enterprise are by quote. |
One plan is published. Business and Enterprise are quoted, and contacts are bought with data credits.
Company analysis and contact details on Individual draw down data credits, so the 1,000 credits cover a limited list. Traffic history is 3 months on Individual and 25 or 37 on the higher plans. Similarweb’s Web Intelligence plans are a separate product with separate pricing.
A flat-rate plan with credits included, or a custom plan built around your deals.
Contacts are charged only when one is found. Exports are free.

Scores, segments and matched signals go back to your CRM, or into Apollo, Instantly or Lemlist sequences.
Expect rules, filters and signals you set, because a model of your own deals is not what it leads with; ask for a test on your accounts.
Expect an accuracy claim, because vendors measure it on their own samples; test find and bounce rates on your own list.
