TL;DR
- Choose Bombora if the part of 6sense you use is third-party, company-level research on business topics. You will still need account matching, scoring and a way to put the signal in front of sellers. Obtain a quote for topics, coverage, delivery and reuse rights.
- Choose G2 Buyer Intent if you sell software and care about company activity around product profiles, category pages, comparisons and pricing on G2's research network. The signal is narrower but more concrete; each listed product needs its own eligible subscription and category volume needs testing.
- Choose Leadfeeder (formerly Dealfront) if the crucial job is identifying companies visiting your own site and routing useful account visits into CRM. Lite is free; Discover starts at €79 per month billed annually at the entry identified-company volume. It is not a replacement for broad off-site topic research.
- Choose Common Room if several signals, community, product, web and CRM activity, need one account and contact workflow. Its Essential plan is publicly listed at $2,500 per month billed annually, so it may reduce unused suite scope without being cheaper. The public API is an inbound path, not an outbound intent-data feed.
- The right alternative depends on which 6sense workflow is actually used. Its revenue-marketing platform also includes advertising, email agents, workflows and reporting. Replacing one intent feed does not replace the whole suite. Map current jobs, costs and owners before canceling it.
Which part of 6sense are you replacing?
“We need intent data, not a full ABM suite” is a useful starting point, but it is not yet a product requirement. A sales team might only use an account-priority field in Salesforce. Marketing might use 6sense to identify anonymous website traffic, build segments, buy ads and report account progression. A data engineer might depend on its company-identification API. If the buyer cancels the platform and purchases a topic feed, only the first part of that system may survive.
The current 6sense Revenue Marketing page describes buyer signals together with advertising, email agents, intelligent workflows and cross-campaign reporting. Inventory the actual use in your organization. For each workflow, record the input, owner, action, monthly volume, report used to judge it and what breaks if it disappears. Delete unused dashboard views from the shopping list; retain the processes that demonstrably create useful account actions.
Separate four layers:
- Evidence: a visit to your site, marketplace comparison, community discussion, product event or elevated research around a topic. These are not interchangeable.
- Identity: which CRM account does the evidence belong to? A domain can map to a parent and regional subsidiaries.
- Decision: does the account fit your ICP, is the signal recent and strong enough, and does an open opportunity already have an owner?
- Activation: does the seller get a research task, does marketing build an audience, or does nothing happen? A score nobody uses is not a workflow.
A lighter architecture can buy the evidence from one vendor and use the existing CRM, marketing platform or warehouse for the other layers. But that creates integration and governance work. The sensible question is whether those costs are lower than the 6sense capacity the team actually consumes, not whether a smaller logo looks less expensive.
Four alternatives compared
| Alternative | Evidence it provides | Best when | What it does not replace | Public commercial boundary |
|---|---|---|---|---|
| Bombora Company Surge | Company-level increase in research on chosen topics | Off-site topic demand is the missing input | Website identity, advertising and full campaign orchestration | Quote needed for topics, account coverage and delivery |
| G2 Buyer Intent | Product, pricing, category and comparison research in the G2 network | Software buyers research relevant categories there | General web topic demand or your own site visits | Plan and signals depend on subscribed product |
| Leadfeeder | Likely companies visiting your own site and account activity | First-party web visibility is the actual job | Off-site topic demand or every ABM activation | Lite free; Discover from €79/month billed annually, volume based |
| Common Room | Connected community, product, web and other GTM signals in one workflow | Multiple owned and partner signals need identity and activation | A universal external intent feed or assumed outbound API | Essential $2,500/month billed annually, five seats |
This table compares substitution roles, not performance rankings. The alternatives observe different populations. A vendor that sees fewer accounts may be more useful if those are the accounts your reps can act on; another may be commercially sensible only when several workflows are consolidated.
1. Bombora for topic surge
Bombora's Company Surge describes when a business consumes more content about a B2B topic than it normally does. For a cybersecurity company selling to enterprises, a rise around a carefully selected group of identity or data-protection topics can prioritize account research before that company visits the seller's site. It is an account-level pattern, not proof that a named buyer is in procurement.
Bombora fits when a team already has a CRM, a target-account list and a route from a qualified account signal to a representative. Ask for the actual topic catalogue, company matching, lookback period, update cadence, reporting threshold, delivery option and geographic coverage in your categories. Test broad and narrow topics side by side: a broad term may generate many accounts that are curious but irrelevant, while a niche term may produce too few to operate a weekly queue.
Preserve the topic and observation window when the signal enters the CRM. A generic “surging” badge gives the rep little basis for a useful call. The action should be a research task: verify fit, look for a real company change and identify an appropriate contact. Do not tell a prospect “we know you were researching this topic” as though the source identified them personally.
Bombora is a poor standalone replacement if the team relies on 6sense's advertising audiences, on-site identity or predictive stages. These would need another system or a deliberate decision to stop using them. Because a full current price for the exact topics and delivery is not publicly established, seek a written quote rather than treating an old category price as a reliable subscription cost.
2. G2 for software buyer research
G2 Buyer Intent observes actions such as views of product profiles, category pages, pricing pages, alternatives and comparisons on its marketplace network. Its current documentation says the available signal types depend on the subscribed plan and that each G2-listed product needs its own Buyer Intent subscription. A software company with active category research can obtain a more specific clue than a broad topic score: an account has looked at a category or a comparison page. The signal still names an organization, not a particular employee.
This is strongest when you sell in a category with enough relevant traffic and your product and competitors are represented accurately. Ask for a historical sample from the exact category and countries you sell into. A large global signal count can hide an almost empty niche geography. Filter the sample to ICP accounts and measure how many generate useful seller tasks each month. Then check whether the specific comparison, alternative and pricing signals you want are included in the proposed product plan.
G2's API data reference lists company identifier and domain, page URL, visit type, date, last-seen time and buying stage. That helps a data team preserve source context. If a rep receives “decision stage,” they should be able to inspect the underlying permitted page activity and when it happened. A modelled stage is useful for prioritization but should not be quoted to a buyer as a statement of their internal purchase process.
G2 is not a replacement for broad topic research across the web or company visits to your own site. It may also be a poor fit if the relevant category draws little buyer activity or the team sells several products that each require an additional subscription. Budget the product-level entitlements and integration in one proposal.
3. Leadfeeder for website company visits
The original article named Dealfront. Dealfront now points buyers to Leadfeeder, and Leadfeeder's current site announces the brand change. Evaluate Leadfeeder (formerly Dealfront) under its current packages. Treating Dealfront and Leadfeeder as separate alternatives would confuse procurement and duplicate a product in the shortlist.
Leadfeeder associates website activity with likely visiting companies, exposes pages and account context, and supports alerts and CRM workflows. This is valuable if the team mainly wants to know which target accounts return to the pricing, integration or implementation pages. It is first-party website evidence, not a substitute for off-site research from Bombora or G2. A visit can be useful for timing without proving that the account has a budget or that a specific employee browsed.
The pricing page shows Lite free with seven days of history and the last 100 companies per month. Discover starts at €79 per month billed annually for up to 50 identified companies; price rises with company volume. Activate begins at €369 per month on annual billing and adds contact and activation features. The right comparison is the plan and volume your site needs, not the €79 headline if a typical month identifies several hundred companies. Ask what counts toward volume, what remains accessible after downgrade and which CRM action is included in the purchased plan.
Leadfeeder is a weak replacement for a team whose principal 6sense use is off-site topic research or multi-channel ABM reporting. It can be a strong, inexpensive first test for a smaller team whose actual 6sense usage has narrowed to a weekly company-visit list. Pilot exact account and regional-subsidiary matching; a parent-company label sent to the wrong owner is not a qualified signal.
4. Common Room for a combined signal workflow
Common Room is different from the three evidence feeds. It brings connected signals from community, product, web and GTM systems into account and contact workflows. It can make sense when sales and marketing already have several signal sources but cannot resolve identities, prioritize accounts or coordinate follow-up. The buyer should evaluate which sources are natively connected, which require implementation and whether the output is a seller task, a segment or another action.
Its public Essential plan is $2,500 per month billed annually, with five seats and up to 100,000 contacts, plus listed credits and selected integrations. That is roughly $30,000 per year before extra scope, so “lighter than 6sense” must not be translated into “cheap.” It can be economical if it replaces several underused tools and reduces manual identity work; it is not an efficient purchase for a team that only needs one small visitor feed.
There is also a technical boundary. Common Room's API/Zapier documentation says its public API gets data into Common Room, not out. A team planning to buy it as a machine-readable outbound intent feed for its own warehouse should verify another approved export path, rather than assuming that an “API” label is sufficient. This does not limit its value as an orchestration destination; it changes the architecture.
The non-fit is an organization with no meaningful community or product signal and no owner for the combined workflow. A sophisticated signal layer can become another dashboard if nobody decides which account actions it should trigger.
Three lighter stack designs
The replacement need not be four tools at once. These three designs illustrate different jobs:
| Current 6sense use | Leaner design to test | Work you must own |
|---|---|---|
| “SDRs look at accounts surging on three topics” | Bombora feed → existing CRM account match → reviewed research task | Topic choices, score/recency rule, rights, alert dedupe |
| “Product marketers use competitive research alerts” | G2 signals → CRM or existing marketing platform → category-specific account queue | Product subscription, account matching, geography filter, action owner |
| “Sales checks which target accounts revisit our site” | Leadfeeder Discover → CRM company mapping → task for relevant repeat visits | Tracking configuration, correct regional entity, volume tier, suppression |
If the team's real need is to combine those sources with community or product events, Common Room can be an alternative orchestration layer. But that is a fourth design with a materially higher public starting contract and possible overlap with existing tools. Do not build a four-vendor stack to replace one 6sense workflow; let the inventory of used jobs determine components.
The CRM should remain the action record if sellers work there. Store provider, observation time, matched account, event or topic, policy version and owner. Distinguish a company visit from a marketplace comparison and a relative topic surge. Apply fit and recency before creating a task, and avoid duplicate alerts on the same account while an opportunity is active. A small, explainable queue is more valuable than another “high intent” field that changes without context.
What will the replacement cost?
Ask Finance for the current 6sense contract and identify the products, seats, media spend and implementation work included. Do not compare a Bombora data quote with the entire 6sense invoice if some 6sense capabilities will remain. Conversely, do not call a narrow subscription a saving while paid advertising, CRM integrations and attribution have to be bought again elsewhere.
Create a year-one and recurring-year sheet. For every replacement component, add licence or minimum term, required products/topics and volume, activation channels, implementation, data operations, analyst review and any vendor media or contact credits. Leadfeeder and Common Room give public anchors: at entry volume, Discover is €948 per year on annual billing, while Common Room Essential is $30,000 per year before any additions. They are different currencies and scopes; those two figures cannot be ranked as though they buy the same job. Bombora and G2 require buyer-specific quotes.
Then compute cost per accepted account action. Suppose a narrower setup produces 400 monthly signals, 120 match your ICP, 50 are recent and unique, and reps accept 20 as useful research tasks. A hypothetical $1,000 monthly-equivalent all-in cost would be $50 per accepted task. If only five are accepted, it is $200. This is illustrative arithmetic, not a vendor price or guaranteed return. It captures whether a source and its workflow are useful enough for the team to act on.
Include switching cost and lost evidence. Data history, modelled stages, ad audiences and attribution may not export in a reusable form. A lower annual licence can be a poor trade if migration consumes months or discards the one workflow that influences pipeline. Price the transition explicitly rather than making the new vendor absorb it in a vague “setup” row.
A safe migration test
First, inventory 60 days of actual 6sense usage: which users open which views, which alerts become tasks, which audiences run ads, which fields feed CRM rules and which reports are used by leadership. Agree with each workflow owner what must survive. Request export of allowed account history, segments, suppression state and configuration before a contract deadline. Note any data that cannot be retained under the terms.
Second, run one alternative beside 6sense for four weeks on a fixed target-account list. Do not compare score numbers: Bombora's relative topic change and G2's page activity cannot have score parity with 6sense's model. Compare matched-account accuracy, useful new accounts, false positives, accepted seller actions and time to action. Have a rep review the evidence on individual accounts, not merely a dashboard overlap percentage.
Third, test the operational path. A signal for an existing opportunity should go to its owner or be suppressed under the approved policy. A parent/subsidiary collision should reach an analyst, not a random territory. A cancelled subscription, expired token or failed CRM sync should create an alert for RevOps rather than silently emptying the queue. Record how much manual work the lighter design actually introduces.
Only after the replacement passes the defined workflow should the team remove the old 6sense automation. Keep a brief overlap window to spot missing tasks, then retire old score fields and audience rules deliberately. Leaving both models live can cause conflicting routes and reports. The migration is complete when a seller can explain why an account appeared, act on it, and see the outcome in the system of record.
Which alternative should you buy?
Buy Bombora for company-level topic research when you already have a practical activation path. Buy G2 for specific software-research activity if your category has enough relevant buyers and the product subscription covers the needed signals. Buy Leadfeeder when the real job is first-party website company identification and its volume-based plan covers the CRM handoff. Buy Common Room when multiple signal sources need a shared identity and workflow layer and the team can justify its enterprise starting price.
Keep 6sense if the organization uses the suite's predictive, advertising, email and reporting components together and can demonstrate that the integration between them is worth the contract. A narrower provider is not automatically better. The buyer wins by matching the purchased system to the workflows it actually runs. For a broader platform comparison, see 6sense vs Demandbase; for source choice, see our B2B intent data providers guide.
The ABM Playbook helps define the account-selection process before choosing an intent product or committing to a wider suite.
FAQ
Is Bombora a full replacement for 6sense?
No. Bombora can supply company-level topic research. If you currently use 6sense for account identification, predictive stages, advertising, email, orchestration or reporting, those functions need a separate plan or an explicit decision to stop using them.
Can G2 Buyer Intent show that an account is comparing products?
Its documentation describes compare, alternatives, category, product and pricing signals in its research environment. Availability depends on the subscribed product and plan. The account-level signal does not establish which employee visited or that a purchase is approved.
Is Dealfront a separate alternative from Leadfeeder?
No. Dealfront now directs buyers to Leadfeeder, and Leadfeeder's site announces the brand change. Evaluate the current Leadfeeder packages rather than counting the old and new names as two vendors.
Is Common Room cheaper than 6sense?
It depends on your 6sense contract and the functions you replace. Common Room Essential is publicly listed at $2,500 a month billed annually. It could consolidate several workflows, but is not a low-cost substitute for one narrow signal feed.
What should be exported before a 6sense contract ends?
Request any permitted account history, audience and segment definitions, suppression rules, field mappings and workflow configuration. Record what cannot be exported or retained. The new provider's signal scores are not interchangeable with the old model, so retain decision logic separately.
How should a seller use a new intent signal?
The task should show the account, source, observed activity or topic, timestamp, fit and recommended research step. It should not claim a specific person's behavior or label the account “ready to buy” without evidence.
