Vector vs Warmly (2026)
Vector and Warmly both name individual website visitors, then spend that knowledge in different places. Vector puts it into advertising: identified people become audiences on LinkedIn, Google and Meta that refresh as they move through a buying journey, target accounts are scored with a model the buyer can read, and Stories ties pipeline back to the campaigns. Warmly puts it into conversation: an AI or live chat on the page, an alert and routing to a rep, automated email follow up, and a TAM Agent running outbound to accounts that showed intent elsewhere. Both are bought through sales. Vector sells one annual contract with every module included and unlimited seats, priced by usage, with presets at $36,000, $60,000 and $96,000 a year; Warmly's identification plan starts at $10,000 a year and chat at $20,000. Vector also explains where its identity data comes from, a publisher network sharing hashed emails and device fingerprints. Warmly gives the number of data vendors in its waterfalls but not who they are or how the data was gathered.
- Paid social and search are the main channel, and identified buyers should become LinkedIn, Google and Meta audiences without manual list work.
- Marketing needs attribution that connects campaigns to pipeline, which Stories provides inside the same contract.
- Legal review wants the data source described: a publisher network, device fingerprint matching, an opt in geofence and no pooling of the customer's own visitors.
- Sales wants to talk to the visitor during the session, by AI chat, live chat or a call from an AI agent.
- A smaller first commitment matters, with identification from $10,000 a year or $4,875 a quarter.
- Outbound to accounts that have not visited should run on the same signals, with outbound and nurture campaigns managed by the TAM Agent.

The short version of each
Vector
Vector is an account based marketing platform with contact level identification at its base. It names individual visitors, scores target accounts with a model a marketer can read, maps buying committees and their journeys, and pushes identified people as audiences to LinkedIn Ads, Google Ads and Meta Ads, refreshed as behavior changes. Stories attributes pipeline to campaigns, Slack notifications alert reps, and Salesforce and HubSpot receive contacts; Vector MCP and a partner API with webhooks open the data to other tools. Identity comes from publishers sharing hashed emails and device fingerprints, limited to jurisdictions with an implied opt in basis. One annual contract covers everything, with presets from $36,000 a year. The GTM Tech Index grades it B for the provenance of that data, and B on platform terms, since audiences reach ad networks through their own interfaces.

Warmly
Warmly turns an identified visit into immediate action. When a named person or company lands on the site, it can alert the account owner in Slack, route the lead, start an AI or live chat, show a personalized popup or landing page and send retargeting through email and LinkedIn ads, with AI written follow up after the session. Its TAM Agent extends the same signals to accounts that never visited, scoring intent with machine learning, tiering accounts against the ideal customer profile and running outbound and nurture campaigns. Warmly says its contact data is verified across more than 15 vendors and reports 95% deliverability on verified emails. The GTM Tech Index grades Warmly C on deliverability, since its agents send email without a documented sending discipline, and C on data licensing, as the sources behind person level identification go unnamed.

Common questions
Where do Vector and Warmly get the identity data that names visitors?
Vector says it runs a network of publishers who collect and share first party data as hashed email addresses with device fingerprints, matches only the fingerprint against a pre existing identity graph, uses no form fills or third party cookies, and keeps a customer's own visitors out of the shared pool. Warmly assembles identity through verification waterfalls, four vendors for matching an IP address to a company, two for domains and three for matching email to a person, out of more than 15 in all, without naming them. On data licensing and provenance the GTM Tech Index puts Vector at B and Warmly at C.
Is Vector or Warmly better for LinkedIn advertising?
Vector is built around it: identified people and buying committees become audiences on LinkedIn Ads, Google Ads and Meta Ads that refresh as behavior changes, a bid agent works alongside the campaigns, and Stories attributes pipeline to them. Warmly retargets identified visitors through email and LinkedIn ads and offers LinkedIn ad targeting in its TAM Agent. The GTM Tech Index grades Vector B on platform terms exposure, because audiences enter each ad network through its own interface, and Warmly C, as its outreach across email and LinkedIn runs with no stated method.
What does a first year of Vector or Warmly cost?
Vector publishes three annual presets for its whole platform, $36,000, $60,000 and $96,000, with unlimited seats; the actual contract is priced from target accounts, signal volume and audience size, and ad spend is paid to the networks on top. Warmly starts at $10,000 a year for identification, $20,000 with chat and $30,000 for the autopilot, with quarterly billing to try it and two $10,000 add ons. Vector sits at B on commercial transparency in the GTM Tech Index and Warmly at C.
Can Vector or Warmly chat with a website visitor?
Warmly can, through an AI chatbot, live human chat, popups and an AI call agent, and its autopilot plan lets the agent qualify and follow up on its own. Vector does not engage the visitor on the site; it sends sales notifications to Slack when an ideal visitor arrives or a tracked account shows a signal, and leaves the conversation to the rep. Graded by GTM Tech Index against seventeen capability axes from each vendor's own published materials, verified October 13, 2026. No vendor pays for placement.
Do Vector and Warmly work for visitors in Europe?
Vector restricts identification to jurisdictions with an implied opt in basis and lets a customer place its script behind a consent management platform, so territories that require express consent are left out; the list of covered jurisdictions is not published. Warmly publishes no geographic limit and carries a privacy notice for the European Economic Area, the UK and Switzerland, with data processed in the United States. On outreach compliance posture the GTM Tech Index places Vector at B for that geofence and Warmly at C.
