By Rahul Bageria, co-founder · Updated June 2026


The 30-second verdict

Same demand, different buyer

Both reveal website visitors and read intent. They split on whether you want people worked into outreach or accounts worked through ads and attribution.

Warmly leads with people and AI agents

Company and person-level reveal, a context graph that unifies signals, and AI agents that chat, route, and work the warm visitor into outreach. Priced like a platform.

Factors.ai leads with ABM and attribution

Company-level reveal, LinkedIn and Google ad orchestration, and multi-touch attribution across the funnel. A far lower entry price for marketing and RevOps teams.

Pick Warmly if
  • You need person-level reveal, not just the company
  • SDRs and AEs will work the warm visitor into outreach
  • You want AI chat, routing, and outbound agents in one

The basics

What each tool actually is

Warmly

Person-level reveal plus AI agents

An AI-native platform that de-anonymizes website visitors at company and person level, then orchestrates outreach around them. A context graph unifies first, second, and third-party signals, while an Inbound Agent runs AI chat and routing and a TAM Agent scores accounts and coordinates email and ads. Best for SDR and AE teams that want to act on the warm visitor.

Visit Warmly

Factors.ai

ABM ads plus attribution

An AI ABM and attribution platform that de-anonymizes visiting companies via reverse-IP, then runs ABM on LinkedIn and Google and measures what works. It scores accounts, syncs ad audiences with LinkedIn and Google AdPilot, and runs multi-touch attribution across website, ads, CRM, and G2 intent. Best for marketing and RevOps teams that own ads and reporting.

"Limited" means available but not a core strength. Warmly is built for person-level reveal and outreach, while Factors.ai is built for company-level ABM ads and attribution, so each leaves out what the other leads with.


Ratings & reviews

What real users say

Public review scores and the themes that come up most, checked June 2026. Counts drift, so the live links are the source of truth.

Warmly

G2
4.6/5 · 203 reviews

Praised for: real-time lead-gen insight that catches visitors you would otherwise miss, strong person-level data, and easy setup with clean HubSpot, Salesforce, and Slack integrations.

Watch-outs: data accuracy that is inconsistent on smaller companies and anonymous traffic, occasional filter and integration bugs, and a steep price cliff that prices out SMBs.

Factors.ai

G2
4.5/5 · 179 reviews

Praised for: ease of use and fast time-to-value, actionable account intelligence with strong intent data, and responsive support with deep analytics.

Watch-outs: company-level only with no person-level detail, a steep learning curve and technical UI, and add-on sticker shock where AdPilot and Interest Groups each cost about as much as the base plan.

Read the scores in context. We show only G2 here because it is the one platform with a credible base for each tool. Their Capterra and Trustpilot samples are too small to be representative, so a single number from them would mislead more than it informs. Weigh the themes alongside the score.


The deciding factors

Where each one actually wins

Six things separate these tools in practice. Here is the honest call on each.

Person-level identity

Edge: Warmly

This is the cleanest dividing line between the two. Warmly reveals visitors at both company and person level, so you get a name and a contact to act on. Factors.ai is company-level only, identifying the visiting account via reverse-IP with no person-level detail. If your motion needs the individual, not just the logo, Warmly is the one that surfaces it.

AI agents and outbound orchestration

Edge: Warmly

Warmly's Inbound Agent runs on-site AI chat, smart popups, and routing, while its TAM Agent maps the buying committee and coordinates email and ads, with warmup and Slack alerts built in. Factors.ai scores accounts and feeds ads, but it does not run outreach agents. For working the warm visitor straight into a sequence, Warmly has the deeper layer.

LinkedIn and Google ABM ads

Edge: Factors.ai

Factors.ai runs LinkedIn AdPilot and Google AdPilot to sync ABM audiences and measure ad ROI, which is core to the product. Warmly runs LinkedIn and email retargeting against revealed visitors, but does not match the Google side or the ad-spend reporting. For target-account ads across both networks, Factors is built for it.

Marketing attribution

Edge: Factors.ai

Factors.ai runs multi-touch attribution across website, ads, CRM, and G2 intent, with predictive scoring on its Growth plan. Warmly is built around reveal and outreach, not attribution reporting. If you need to see which channels and campaigns drive pipeline, Factors is the tool designed for that question.

Pricing and entry cost

Edge: Factors.ai

Both have a free tier, but the paid step is very different. Factors.ai moves to $399 a month on Basic and $999 on Growth, with unlimited seats. Warmly jumps from the free tier to $10,000 a year for de-anonymization, with agent tiers from $15,000 to $30,000. For a team starting paid, Factors is the far lower bar, though add-ons lift both.

Data accuracy

Edge: split

Neither identifies everyone, and both thin out on smaller companies and anonymous traffic. Factors reports matching about 75% of visiting companies. Warmly is praised for strong person-level data but criticized for inconsistency on smaller firms. Match rates depend on your traffic mix, so treat either reveal as a strong signal, not a complete picture.

Pricing

What each one costs in 2026

Verified from each official pricing page in June 2026. Read the metering, not just the headline number.

Warmly

USD / annual, credit-metered
  • Free
    up to 500 de-anonymized visitors a month
    $0
  • AI Web-Deanonymization
    10,000 credits a month, company and person reveal
    $10,000/yr
  • AI agent tiers
    TAM Agent, Inbound Chat, Inbound Autopilot
    $15,000 to $30,000/yr

Credit-metered, so traffic burns the monthly allotment. GTM Signals and Warm Experiences add-ons are $10,000 a year each. Full stacks are reported at $45,000 to $100,000 a year.

Factors.ai

USD / annual, per accounts
  • Free
    up to 200 accounts a month, unlimited seats
    $0
  • Basic
    3,000 accounts a month, 5 seats
    $399/mo
  • Growth
    8,000 accounts, predictive scoring, attribution
    $999/mo

Enterprise is custom. Overages run $100 per extra 500 accounts and $25 a month per extra seat. Add-ons priced separately: LinkedIn AdPilot $1,000 a month and Interest Groups $750 a month.

True cost at scale. Both published tiers are a floor. Warmly is credit-metered, so high traffic burns the monthly allotment fast, and the jump from a 500-visitor free tier to a $10,000 a year entry plan is a hard cliff. On Factors.ai, real ABM needs the LinkedIn add-on, so Basic plus AdPilot is $1,399 a month and with both add-ons $2,149, while Growth with both runs about $2,749, before account overages bite on traffic spikes.


The honest gap

What neither tool does well

Both reveal demand, so they share the same blind spots. Worth knowing before you expect either to carry your whole motion.

Booking the meeting

Both surface intent and can trigger outreach or ads, but neither books the call for you. Turning a reveal into a meeting still needs a person working it.

Accuracy on small firms

Match rates thin out on smaller companies and anonymous traffic. Neither identifies every visitor, so the reveal is a strong signal, not a full picture.

Running the whole stack

Neither replaces a CRM or a full sequencing stack. They sit as a signal layer on top of the tools that actually move the deal.

Want the right accounts found and timed on real signals, then worked into booked meetings? That is the signal-based outbound we run. Building the email side too? See our best cold email tools for 2026.


How we'd choose

Our take, after running both

This is really people-versus-accounts, and who owns the tool. Here is how we'd call it in three situations.

1
SDR-led and outreach-first, pick Warmly

Person-level reveal plus AI chat and outbound agents turn a warm visitor into a worked lead, if you can carry the platform price.

2
Marketing-led ABM and ads, pick Factors.ai

Company reveal, LinkedIn and Google ad orchestration, and attribution at a far lower entry fit marketing and RevOps teams.

3
Either way, reveal is not pipeline

Both tell you who showed interest. Neither books the meeting or picks the right accounts. The targeting and the follow-through are still on you, or on us.

Not sure which fits? We run signal-based outbound for early-stage teams and will tell you straight.

FAQ

Questions buyers ask

Is Warmly or Factors.ai better for website de-anonymization?
It depends on whether you want people or accounts. Warmly reveals visitors at company and person level and works the warm visitor into outreach with AI agents, so it fits SDRs and AEs. Factors.ai reveals visiting companies, runs ABM on LinkedIn and Google, and measures attribution, so it fits marketing and RevOps. Person-level versus company-level is the cleanest dividing line.
Does Warmly show person-level visitor data?
Yes. Warmly identifies visitors at both company and person level and unifies first, second, and third-party signals in a context graph. Factors.ai is company-level only, identifying the visiting account via reverse-IP, with no person-level detail. If you need a name and a contact rather than just the company, Warmly is the one that surfaces it.
Which is cheaper, Warmly or Factors.ai?
Factors.ai, by a wide margin at entry. Factors starts free, then Basic is $399 a month and Growth is $999 a month, billed annually. Warmly has a free tier up to 500 visitors, then jumps to $10,000 a year for AI Web-Deanonymization, with agent tiers from $15,000 to $30,000 a year. Both prices were verified June 2026, and both add real cost once you include add-ons or scale.
Which is better for marketing attribution?
Factors.ai. It runs multi-touch attribution across website, ads, CRM, and G2 intent, which is core to the product. Warmly is built around visitor reveal and AI outreach agents, not attribution reporting. If you need to measure which channels and campaigns drive pipeline, Factors is the tool designed for that job.
Which is better for LinkedIn and Google ABM ads?
Factors.ai. Its LinkedIn AdPilot and Google AdPilot sync ABM audiences and measure ad ROI, which Warmly does not match. Warmly does run LinkedIn and email retargeting against revealed visitors, but for syncing target-account audiences into LinkedIn and Google and reporting on spend, Factors is the stronger fit.
How accurate is the visitor data from Warmly and Factors.ai?
Both thin out on smaller companies and anonymous traffic. Factors reports identifying about 75% of visiting companies, and Warmly is praised for strong person-level data but criticized for inconsistency on smaller firms. Neither identifies every visitor, and match rates depend on your traffic mix. Treat the reveal as a strong signal, not a complete picture, and verify before you act.
Can Warmly or Factors.ai replace an SDR or a CRM?
No. Both surface intent and can trigger outreach or ads, but neither books the meeting for you, and neither replaces a CRM or a full sequencing stack. They tell you who is showing interest; turning that into a booked call still needs a person, a sequencer, and the targeting around it. They are a signal layer, not the whole motion.
