Intent data for SaaS lead generation

Intent data gets sold as a lead source and bought as a lead source, which is why most programmes disappoint within two quarters. It’s a ranking function. It tells you which of the accounts you were already going to work deserve attention first, and it says almost nothing useful about accounts outside your list.

Get that framing right and intent earns its cost. Get it wrong and you’ve paid $45,000 for a spreadsheet.

What each type of intent data actually observes

Three categories, and they observe genuinely different things. Confusing them is the root of most bad expectations.

First party data is behaviour on surfaces you own: pricing page visits, docs searches, feature usage inside a trial, seat additions, a second user from the same domain signing up. It’s the highest fidelity signal you will ever get because you observed it directly, and it’s free apart from instrumentation work.

Second party data comes from review marketplaces. When an account browses your category on G2 or views a competitor’s Capterra profile, the marketplace knows. That buyer is comparing vendors, not idly reading, which makes this the highest converting external signal available.

Third party data is inferred. Providers run co-ops of publisher sites, watch content consumption by IP, resolve the IP to a company and report topic surges. The account is usually real. The topic is usually right. What you don’t get is a person, a role, or any sense of where they are in a buying process.

Type	What it observes	Typical fidelity	Decay window	Cost
First party	Your own site and product behaviour	High, directly observed	Hours to days	Engineering time
Second party	Category and competitor browsing on G2, Capterra, TrustRadius	High, active comparison	7 to 14 days	$15K to $60K per year
Third party	Topic consumption across publisher co-ops, IP resolved	Moderate, inferred	14 to 30 days	$25K to $80K per year
Deanonymisation	Identity of anonymous site visitors	25% to 55% match on US traffic	Same session	$8K to $40K per year

Why intent is a prioritisation input and not a lead source

Because a signal is not a person and a person is not a conversation. An intent record tells you an account showed activity around a topic. It does not tell you the CFO approved a budget line, or that anyone at the account would take your call.

Run the arithmetic. A mid-market team gets 400 surging accounts a month from a third party provider. Suppose 55 percent are already in some stage of your funnel or outside your ICP, leaving 180 genuinely new. Your SDR team can work maybe 60 accounts a month properly. So the data’s practical job is choosing which 60, which is exactly what a ranking function does.

That’s a real and valuable job. It’s just not the job people buy it for. The lead source mix research shows how small a share of pipeline pure outbound produces at most companies, and intent doesn’t change that ratio, it improves the hit rate inside it.

Five plays that actually produce conversations

Each of these has a specific trigger, a specific window and a specific message. Generic “we noticed you were researching” emails fail because they’re creepy and vague at the same time.

Marketplace category surge follow-up

Trigger: your account appears in a G2 or Capterra buyer intent feed for your category or a named competitor. Window: 72 hours, no longer. The buyer is shortlisting now.

Message: lead with the comparison, not the observation. “Most teams evaluating us against Monday are deciding on the resourcing view. Here’s how ours works in 90 seconds.” Send a Loom, not a calendar link. Conversion from this play typically runs 3 to 8 times better than cold outbound in the same segment.

Deanonymised account retargeting

Trigger: an identified account visited pricing, security or integration docs without converting. Window: 7 days. Play: a tightly targeted LinkedIn campaign to 5 to 15 named roles at that account, running creative specific to the page they visited.

Don’t email them saying you saw them on your website. That converts badly and generates complaints. Advertise instead. The ad feels like coincidence, the email feels like surveillance.

Product usage triggers

Trigger: inside a trial, a second user from the same domain invites a third, or usage crosses a threshold you know correlates with conversion. Window: hours.

This is the highest yield play in the list and it needs no vendor. It needs an event in Segment or PostHog, a rule, and a Slack alert to whoever owns that account. Companies routinely pay $50K for third party intent while ignoring the free version sitting in their own product telemetry.

Job change alerts

Trigger: a champion who used your product at a previous company starts a new role. Window: 30 to 90 days, because new leaders buy tools in their first two quarters.

Clay and Apollo both surface this. The message writes itself and it’s the only outbound in this list where a cold email genuinely feels welcome, because you have a real prior relationship.

Competitor page visits

Trigger: an identified account reads your “versus competitor” or alternatives page. Window: 14 days. This buyer is deep in evaluation.

Route these to a salesperson directly rather than into nurture. A comparison page visit from a target account is worth more than most demo requests, and it usually gets treated as a pageview.

What it costs and where the payback breaks

Build the model before the pilot, not after the invoice.

A typical mid-market setup: a third party intent platform at $45,000 a year, visitor identification at $18,000, plus the SDR capacity to work the output. Call it $63,000 in tooling. If the programme prioritises 720 accounts a year and your team works 500 of them, the tooling cost per worked account is $126, before any human time.

Now the conversion side. If signal-prioritised outbound converts to opportunity at 6 percent versus a 2.5 percent baseline, those 500 accounts produce 30 opportunities instead of 12.5. The 17.5 incremental opportunities cost $3,600 each in tooling alone. At a 25 percent close rate that’s 4.4 incremental customers, or roughly $14,300 of tooling cost per customer.

ACV	Tooling cost per incremental customer	Gross profit year one at 80% margin	Verdict
$6,000	$14,300	$4,800	Never pays back
$15,000	$14,300	$12,000	Marginal, needs multi-year retention
$40,000	$14,300	$32,000	Pays back inside year one
$120,000	$14,300	$96,000	Clearly worth it

That table is why the ACV floor sits around $15,000. Below it, put the money into first party instrumentation and inbound lead generation, which scales without a per-account cost. Model your own volumes in the lead goal calculator first.

The privacy constraints you cannot design around

In the EU, IP addresses and cookie-derived identifiers are generally personal data under GDPR. Person-level deanonymisation of a site visitor without consent is not defensible, whatever a vendor’s sales engineer tells you. Several providers now disable EU person-level matching entirely rather than argue the point.

Account-level resolution from a corporate IP range sits on firmer ground, because you’re identifying an organisation rather than an individual. That’s still a processing activity you need to document, and your cookie banner has to reflect it honestly.

Practical positions that hold up:

• Account-level identification for EU traffic, person-level only for US and Canada.
• No emails that reference observed browsing behaviour. Advertise to those accounts instead.
• A data processing agreement with every intent vendor, and a note in your privacy policy naming the category of processing.
• Suppression lists honoured across providers, not just in your ESP.

The reputational risk is larger than the legal one. One prospect posting your “I saw you were on our pricing page” email to LinkedIn does more damage than the tooling ever earned.

How intent fits alongside your other sources

Intent improves outbound efficiency. It does not replace demand creation, and it competes for budget with things that do.

If you’re choosing between a $60,000 intent contract and a $60,000 content programme, the content programme creates demand that intent tools can later detect, and the intent contract detects demand someone else created. At most companies under $20M ARR the content programme wins that argument. Above that, when you already have category presence, intent starts earning its place.

Compare it honestly against outbound lead generation and referral lead generation, both of which produce higher converting conversations at lower tooling cost. For a side by side of the platforms themselves, see intent data providers compared and the tools directory.

What to do next

Instrument your own product and comparison pages before you buy anything, then run a 14 day parallel pilot on two providers and compute the match rate yourself. Pick the play that fits your motion, give it one owner and a response window measured in hours.

Then set up the control group on day one. Two quarters from now it’s the only thing that will settle the renewal conversation, and it costs nothing to start.
