Every founder who starts researching account prioritisation eventually runs into the same two names: 6sense and Demandbase. The pitch is seductive — software that tells you which companies are about to buy so you stop wasting time on cold outreach. It is easy to assume that if the market leaders sell something, you ought to want it, and that buying earlier puts you ahead. Before you put either on a shortlist, though, it is worth understanding what intent data actually is, what these platforms genuinely cost to run once you count the human time, and whether your sales motion is even at the stage where the data would change a single decision. For most founders, the honest answer is not yet — and there are cheaper, faster options that work right now, today, with no contract and no analyst. This guide walks through each one so you can spend on the thing that actually moves pipeline rather than the thing with the best demo.

What Intent Data Actually Is

Intent data tells you which companies are actively researching topics related to your product. It works by tracking signals across the web — which firms are browsing relevant content, engaging with your competitors, downloading comparison guides, or searching for the kind of solution you sell. Vendors aggregate these signals from publisher networks, review sites, and their own tracking, then map the activity back to a company so you can see who is showing buying behaviour. The promise is straightforward: instead of cold-calling the entire market, you prioritise outreach to accounts that are already in a buying cycle. In theory, that means higher reply rates, shorter cycles, and less wasted effort. The catch is that the value depends entirely on whether you have a motion ready to act on those signals.

The 6sense and Demandbase Reality Check

Let us be direct, because the marketing around this category rarely is. 6sense and Demandbase are the two dominant enterprise ABM platforms, and they are genuinely capable tools — they combine intent signals, account scoring, advertising, and orchestration in ways that smaller tools cannot match. They are also genuinely expensive. Median contracts run around $58,000 a year for 6sense and $65,000 for Demandbase, and that is before the human cost: each typically needs 0.5 to 1 full-time person to configure, maintain, and interpret. They were built for companies above $50M ARR with dedicated RevOps teams and defined ICP lists of thousands of accounts. For a founder doing their own sales with a list of 200 to 500 target accounts, the ROI math simply does not work, and the operational overhead would consume more time than the signals save. This is not a knock on the tools — it is a sizing problem, the same way a forty-tonne crane is excellent equipment and the wrong choice for hanging a picture. If you are still building the sales motion these tools would plug into, start here: founder-led sales.

When Intent Data Actually Makes Sense for a Founder

Intent data earns its keep when three things are true at the same time. First, you have a defined ICP list large enough that you genuinely cannot monitor all of it manually — you are tracking so many accounts that human attention no longer scales. Second, you have a repeatable outreach motion ready to act on the signals the moment they appear, so a spike in intent triggers a known sequence rather than an improvised scramble. Third, the signal quality is high enough to trust, meaning a flagged account is far more likely to be in-market than a random name on your list. For most founders under $3M ARR, none of these three conditions is fully met yet. The ICP is still being defined and refined month to month, the outreach motion is still being tested, and acting on a noisy signal burns more hours than it returns. The core point is easy to miss in a sales demo: intent data amplifies a working motion. It does not create one. If the motion underneath is not yet converting, faster targeting just helps you reach the wrong conclusion sooner.

What Founders Actually Use Instead

The tools that make sense at early stage are specific, affordable, and actionable without a RevOps team behind them.

LinkedIn Sales Navigator

LinkedIn Sales Navigator is the obvious first stop at roughly $99 a month. It gives you company and contact-level signals, alerts when someone changes jobs, and the ability to map decision-makers inside a target account. None of that is intent data in the strict sense, but it surfaces the human triggers that actually move deals, and it works alongside any outreach motion you already run.

Apollo.io

Apollo.io sits a step up, combining a prospecting database with basic intent signals for around $49 to $99 a month. The signal quality is not at 6sense's level and you should not pretend otherwise, but for a founder prioritising a list of 200 to 500 accounts it is more than sufficient to separate the warmer names from the cold ones and to pull contact data in the same workflow.

G2 Buyer Intent

G2 Buyer Intent is the most overlooked option of all. If your product is listed on G2, you can see free buyer intent data showing which companies have viewed your profile or compared you against alternatives. The cost is zero and the relevance is high, because someone reading your G2 page is closer to a decision than almost any other signal you can get for nothing.

F5Bot and Reddit Monitoring

F5Bot and Reddit monitoring round out the kit. F5Bot sends free keyword alerts whenever your chosen terms appear on Reddit, Hacker News, and similar forums, letting you catch the symptom-based questions your ICP posts when they are frustrated with a current solution. It is manual and unglamorous, but for an early-stage founder it is a genuinely useful way to find in-market conversations and join them before a competitor does.

The Right Time to Look at 6sense or Demandbase

So when does the math actually flip in favour of enterprise ABM? The honest threshold is somewhere above $5M ARR, with a defined ICP list of 1,000-plus accounts, a repeatable sales motion that has documented close rates, and a RevOps resource — even a part-time one — available to configure the platform and interpret what it produces. Below that line, the operational cost of running 6sense or Demandbase reliably exceeds the pipeline benefit you can extract from it, and the licence fee is the smaller half of the bill. The clearest internal signal that you are ready is not revenue at all: it is that your outreach motion already converts at a predictable rate, and your real constraint has shifted to prioritisation across a large account list rather than finding the motion in the first place. When deciding who to contact has become harder than deciding how to contact them, that is the moment the intelligence layer starts paying for itself. Until then, you are paying enterprise prices to solve a problem you do not have yet, and the budget is almost always better spent on the people doing the outreach or on the offer they are taking to market.

What to Do Instead Right Now

If you want to be smarter about account prioritisation today, you do not need to spend a cent on enterprise tooling. Focus your outreach on accounts showing active symptoms you can spot for free — job postings for sales or growth roles, recent funding announcements, new product launches, leadership changes — because these are the moments when budgets open and priorities shift. Use the free signals first, build the repeatable motion around them, and only buy the intelligence layer once there is a working machine for it to sit on top of. Before adding any intelligence layer, make sure your pipeline fundamentals are solid — a free pipeline velocity calculator shows whether your current motion is healthy enough to amplify. And if your CAC is already unsustainable, intent data will not fix it — check your numbers first with a free CAC calculator. Get the motion converting, then make it faster.

Frequently Asked Questions

Do I need intent data as an early-stage B2B founder?

Almost certainly not yet. Intent data amplifies an existing, repeatable outreach motion — it does not create one. Under roughly $3M ARR, your ICP and motion are still being refined, so a paid intent platform adds cost and overhead without a reliable process to act on the signals.

What is the difference between 6sense and Demandbase?

Both are enterprise ABM platforms combining intent data, account scoring, and orchestration. 6sense is often seen as stronger on predictive scoring and intent modelling, Demandbase on advertising and account-based targeting. For an early-stage founder the practical difference is minimal, because neither fits the budget or team size yet.

What is a cheaper alternative to 6sense for startups?

Apollo.io offers basic intent signals plus a prospecting database for $49 to $99 a month, and LinkedIn Sales Navigator surfaces contact-level triggers for about $99. Neither matches 6sense's signal quality, but both are more than enough to prioritise a list of a few hundred accounts.

When should a startup start using intent data?

Look at enterprise intent platforms once you are above roughly $5M ARR, with a defined ICP list of 1,000-plus accounts, documented close rates, and a RevOps resource to run the tool. The trigger is when prioritising a large list — not finding the motion — has become your main constraint.

Is G2 Buyer Intent worth it for early-stage companies?

Yes, if your product is listed on G2. The basic buyer intent showing which companies viewed your profile is free and highly relevant, because someone reading your G2 page is closer to a buying decision than nearly any other no-cost signal you can access at early stage.
