[Visitor Identification]

Website visitor identification,
wired into revenue.

Your next customer may visit your website without filling in a form. Selleris connects company-level visitor identification to HubSpot, helping B2B SaaS and tech-enabled SMBs spot relevant account activity and prioritize follow-up.

We match identified companies to your existing records, enrich and score them, then route relevant signals to your team and AI agents. The diagnostic defines the scope around your traffic and available data. Accounts and licenses stay in your name.

[The Signal]

What website visitor identification is

Website visitor identification matches anonymous website activity to companies using IP intelligence, first-party signals and identity graphs. Person-level identification is considered separately, where lawful and supported by the selected provider.
Selleris connects those signals to your HubSpot: matching existing records, enriching and scoring accounts, and routing relevant activity to your team and AI agents. A visit helps prioritize follow-up; it does not confirm an intention to buy.
A visit is a signal. Context makes it actionable.
The approach behind it is in the GTM engineering manifesto.
[What We Wire]

From anonymous visit to worked account.

Company-level identification

Company matches and available firmographic data from selected providers, synced and deduplicated in your HubSpot.

Person-level where lawful

US-only person resolution where the law allows; your traffic mix decides the scope in the diagnostic.

Intent signals

Third-party intent, hiring and funding triggers layered on top, so timing beats luck.

Enrichment and scoring

Identified accounts enriched with available data and scored against your ICP, so your team can prioritize the best-fit companies.

Routing and alerts

Relevant activity routed to account owners with available context: pages visited, reported signals and score changes.

Agent-run follow-up

Agents draft the outreach from the visit context; your team approves and sends.

Identification without the tool zoo

We choose identification and intent providers against your traffic mix and connect them to HubSpot. The work is documented and licenses are in your name, so you can develop the system with Selleris or another implementation partner.

Built from: identification providers and intent feeds, with records synced and deduplicated in HubSpot. Provider changes are assessed and scoped separately.

[The Practice]

Visitor identification, scoped in the open.

Start with a free diagnostic and a focused proof of concept. We review your traffic volume, audience mix and existing data, then agree the deliverables, fixed price and commercial terms for a standalone implementation.

Selleris Revenue Loop follows our Build & Improve model. We agree measurable results and one fixed total price for the initial implementation. You pay after those results are achieved and verified, with no upfront Selleris delivery fees. Further improvements are agreed separately, with no automatic monthly retainer.

For EU traffic, we scope company-level identification. Person-level work remains US-only, where lawful and supported by the selected provider. Licenses stay in your name, with provider subscriptions and usage disclosed separately and paid directly to providers with zero Selleris markup.
