Best Intent Data Providers

Cognism is a B2B sales intelligence platform that provides verified business emails and phone-verified mobile numbers, branded Diamond Data, for outbound prospecting. Founded in 2015 and headquartered in London, United Kingdom, Cognism screens its phone data against Do Not Call and TPS registries across markets including the US, UK, Canada, and several European countries. The company acquired the LinkedIn-focused prospecting tool Kaspr in 2022.

Cognism is sold through two sales-led packages, Standard and Pro, each including five seats, with Pro adding phone-verified mobile numbers, Bombora-powered intent data, and on-demand verification. There is no self-serve free plan or trial; prospective customers can request a small data sample or book a demo, and all pricing is quoted individually.

ZoomInfo is a go-to-market platform that gives sales, marketing, and recruiting teams access to business contact data, company profiles, and buying signals. Founded in 2007 and headquartered in Vancouver, Washington, it reports a database of hundreds of millions of contacts and companies built from public records, a contributory network, and ongoing verification. The platform spans product lines including SalesOS, MarketingOS, TalentOS, and OperationsOS, plus an AI layer called Copilot.

Teams use ZoomInfo to build prospect lists, track intent signals such as hiring changes and executive moves, enrich CRM records, and automate outreach through integrations with Salesforce, HubSpot, Outreach, and Salesloft. Pricing is quote based rather than published, with contracts typically billed annually, though a free ZoomInfo Lite tier offers limited monthly credits for smaller-scale use.

Intentsify is a B2B intent data and activation platform covering buyer intelligence, buying group intent, audiences and website visitor resolution on the data side, with digital advertising, lead generation and email marketing on the activation side, plus an identity graph, integrations and published security and compliance material.

Pairing data with activation is the distinguishing decision and it addresses the failure that wastes most intent data spend. A report saying forty accounts are in-market is worth nothing unless somebody acts on it that week, and marketing teams routinely buy the signal without having the campaign machinery or the capacity to use it.

Buying group intent rather than account intent is the more precise unit and the harder problem, since an account showing research activity tells you a company is interested while identifying which committee is researching tells you who to reach, and enterprise purchases are made by committees rather than companies.

Website visitor resolution sits at the other end of the same pipeline, turning anonymous traffic a company has already earned into named accounts, which is usually the highest-intent audience available and the one most often left unworked. Rates are not published. Intentsify publishes security and compliance material alongside the platform, which enterprise buyers treat as a precondition.

G2 Buyer Intent reports which companies are researching a vendor and its competitors on G2, drawn from activity on the review platform itself, and is sold to software vendors through G2's seller solutions alongside profile and category placement.

Owning the surface where the research happens is what makes this data different from the rest of the category. Most intent providers infer interest from content consumption across a network of publishers, whereas G2 observes a named company reading a specific product's reviews and comparing it against two others, which is a far shorter inference from behaviour to intent.

The competitive signal is the most commercially valuable part and the most uncomfortable, since a vendor learns not only that an account is in-market but that it is actively comparing them against a named rival, which is a sales conversation with a deadline attached.

What a buyer should weigh is coverage rather than accuracy: this sees only companies that visit G2, so it is precise about a subset rather than comprehensive across a market, and it works best alongside a broader intent source rather than instead of one. The data is delivered through alerts and integrations into CRM and marketing systems so in-market accounts reach a salesperson while the research is still happening, which is the only window in which the signal is worth anything. Rates are not published.

Bombora is a B2B data provider covering intent, identity and enrichment, digital audiences, campaign measurement and an insights suite, built on a Data Co-op of publishers and sold to agencies, publishers, sales teams and marketing teams.

The Data Co-op is the structural difference from every competitor and it is the reason Bombora's data holds up. Publishers contribute consented content-consumption signals from their own properties and receive value back, so the underlying observations come from a declared arrangement rather than from tracking pixels of uncertain provenance.

That matters increasingly rather than decreasingly, because third-party cookies and opaque data brokerage are exactly what privacy regulation and browser vendors have been closing off, and a co-operative built on publisher consent is a model that survives those changes rather than one that has to be re-engineered around them.

Publishing the intent topics it tracks is a useful piece of transparency, since the practical question for a buyer is whether their category is covered granularly enough to be actionable: knowing an account is researching security software is far less useful than knowing it is researching mobile threat defence.
