5 Best SyncGTM alternatives for B2B Buying Signals Outreach

5 Best SyncGTM alternatives for B2B Buying Signals Outreach

Summarize with

SyncGTM lets you track buying signals like hiring, funding, and job changes, then enrich prospects for outreach.

But its Solo plan costs $49/month and gives you just 1,000 credits. Finding one verified email costs 1 credit, while finding a mobile number can cost 10 credits.

If you're tracking multiple buying signals and enriching hundreds of prospects, those credits can run out quickly.

You may want an alternative with more contact data, different buying signals, or a simpler way to find prospects ready for outreach.

So, I compared 5 SyncGTM alternatives based on their buying signals, prospecting features, outreach options, and pricing.

Let's see how they compare.

Why Users Look for SyncGTM Alternatives

SyncGTM covers signals, enrichment, scoring, and workflow automation in one system. That can be more than you need if your outbound process is centered on one specific type of buying signal.

Users may look elsewhere when they want:

  • A simpler signal-to-list workflow instead of building multi-step GTM workflows around every trigger.
    ‍
  • Signal stacking to combine events like funding, hiring, executive changes, and website activity in the same search.
    ‍
  • Custom buying signals built from specific data points, research, or enrichment fields.
    ‍
  • Account-level intent and buying-stage predictions for prioritizing accounts before prospecting.
    ‍
  • Built-in outreach so a prospect can move from intent detection straight into a sequence.
    ‍
  • More prospecting credits at the entry price if most of your usage goes toward finding and enriching contacts.

The right alternative depends on which part of SyncGTM you actually need most — signal-based prospecting, signal stacking, custom signals, account intent, or outreach.

How I Evaluated the Best SyncGTM Alternatives

SyncGTM helps with buying signals, prospecting, enrichment, and sales workflows. So, I used these same areas to compare the alternatives. I looked at:

  • Finding prospects based on buying signals.
    ‍
  • Enriching leads with verified emails, phone numbers, and company data.
    ‍
  • Qualifying prospects based on ICP fit, buyer roles, and company signals.
    ‍
  • Building workflows that act when a new buying signal appears.
    ‍
  • Moving prospects into email or LinkedIn outreach.
    ‍
  • Pricing, included credits, and usage limits in each plan.

I also looked at what each tool does differently from SyncGTM. This makes it easier to see which alternative fits the part of your prospecting or outreach process you want to change.

1. Leadsforge

Leadsforge homepage
This image shows the Leadsforge homepage

Leadsforge is a SyncGTM alternative if you mainly want to find prospects from buying signals instead of building complex GTM workflows. You can find prospects based on funding, hiring, job changes, acquisitions, and investor activity, then narrow the results using company and contact filters.

Leadsforge then checks 20+ data providers for verified emails, phone numbers, and LinkedIn profiles. From there, you can send the list to Salesforge or export it to another outreach tool.

So, if buying-signal prospecting is the main part of SyncGTM you need, Leadsforge gives you a more focused option.

Why Leadsforge Is a Good SyncGTM Alternative

SyncGTM covers more signal types and can use them inside automated GTM workflows. Leadsforge is more focused on using signals to build prospect lists.

Leadsforge signals

For example, you can find recently funded companies and filter them by funding round, funding amount, industry, country, and company size. For job changes, you can narrow prospects by position, seniority, department, and location.

Once you have the right prospects, you can then enrich the prospects with work emails, LinkedIn profiles, or mobile numbers and move the list into outreach.

So, Leadsforge is a better SyncGTM alternative if you mainly need buying signals to find and enrich prospects, rather than to run multi-step GTM workflows.

Pros of Leadsforge

  • Finds prospects using funding, hiring, job changes, acquisitions, and investor activity.
    ‍
  • Lets you search and filter leads before spending credits.
    ‍
  • Checks 20+ B2B data providers for contact details.
    ‍
  • Unused credits roll over and do not expire.
    ‍
  • Sends leads to Salesforge or lets you export them as a CSV.

Cons of Leadsforge

  • Supports fewer buying signal types than SyncGTM.
    ‍
  • Does not offer the same multi-step workflow automation as SyncGTM.
    ‍
  • You need Salesforge or another tool to run the outreach.
    ‍
  • Verified phone numbers cost 10 credits each, so phone enrichment can use credits quickly.

Leadsforge Pricing

Leadsforge pricing
This image shows the Leadsforge pricing

Leadsforge starts at $49/month with 2,000 credits per month. You can search and filter prospects without using credits. Credits are used when you extract or enrich contact data.

  • Verified work email costs 1 credit.
    ‍
  • LinkedIn profile costs 1 credit.
    ‍
  • Verified phone number costs 10 credits.
    ‍
  • Unused credits roll over and do not expire.

The annual plan costs $588/year and gives you 28,000 credits upfront. For comparison, SyncGTM's Solo plan also costs $49/month, but includes 1,000 credits. So, Leadsforge gives you twice the starting credits if your main need is prospecting and contact enrichment.

2. Bitscale

Bitscale homepage
This image shows the Bitscale homepage

Bitscale is a B2B prospecting and data enrichment platform that lets you find prospects, track buying signals, and enrich contact data. 

It tracks 15 buying signals, including funding rounds, hiring activity, executive hires, job changes, tech-stack changes, LinkedIn activity, and website visits.

You can combine signals in the same search. For example, you could look for companies that recently raised a Series B, are hiring SDRs, and brought in a new VP of Sales. After finding those accounts, Bitscale can pull contact data through 100+ data sources and send prospects to Instantly, Smartlead, or HeyReach.

Why Bitscale Is a Great SyncGTM Alternative

Bitscale gives you some useful signals beyond common company events. You can track viral LinkedIn activity, website visitors, champion job changes, and account engagement.

You can also stack these signals. Instead of contacting every recently funded company, you could narrow the list to funded companies that are also hiring for a certain role or have recently hired a new executive.

SyncGTM covers more of the workflow after a signal appears. It can source prospects, enrich records, score leads against your ICP, keep records updated, and trigger outreach actions. 

Bitscale makes more sense if you want several buying signals to determine which accounts make your outreach list.

Pros of Bitscale

  • Excellent buying signals with 15 signal types.
    ‍
  • Strong signal stacking for combining multiple buying triggers.
    ‍
  • Excellent data coverage from 100+ sources.
    ‍
  • Good enrichment for emails, mobile numbers, and LinkedIn profiles.

Cons of Bitscale

  • Expensive paid plans starting at $349/month.
    ‍
  • Expensive Salesforce access starting on the $799/month Booster plan.
    ‍
  • No native sequencer for sending outreach campaigns.
    ‍
  • Poor fit for smaller prospect lists if you do not need multiple buying signals.

Bitscale Pricing

Bitscale pricing

  • Free: $0 with 200 Bitscale credits.
    ‍
  • Growth: $349/month with 15,000 credits.
    ‍
  • Booster: $799/month with 50,000 credits.
    ‍
  • Enterprise: Starts at $15,000/year with custom credits.
    ‍
  • Credit usage: Credits are charged when a data provider returns a valid result. Failed lookups, formula columns, and CRM syncs do not use credits.
    ‍
  • Annual billing: Growth costs $314/month when billed annually.

At $349/month, Bitscale only really makes sense if you plan to use signal stacking regularly, rather than relying on one trigger at a time.

3. Clay

Clay homepage
This image shows the Clay homepage

Clay is a GTM platform for finding prospects, enriching lead data, tracking buying signals, and building outreach workflows. You can track signals such as website visits, job changes, new hires, funding, social mentions, tech-stack changes, and company news. 

Clay also lets you create custom signals from its 200+ enrichments or from specific information found through its research agents. Once a signal appears, you can add more company and contact data, score the account, find decision-makers, and use the results in your outreach.

Why Clay Is a Good SyncGTM Alternative

Clay is a better fit if you want to build buying signals around data that matters specifically to your business. You can turn any of Clay’s 200+ enrichments or custom research into a signal. That could be a website change, product usage, a competitor mention, specific hiring activity, or another data point you want to watch.

You can then combine several signals with your CRM data, enrich the matching accounts, score them, and decide what action should happen next.

SyncGTM also supports custom signals, but its main signal offering centers on ready-to-use company and person signals such as funding, hiring, tech-stack changes, website traffic, job changes, and promotions. 

So, Clay is the stronger alternative when you need to define your own buying signals and build detailed workflows around them.

Pros of Clay

  • Excellent custom signals from 200+ enrichments and AI research.
    ‍
  • Strong waterfall enrichment across multiple data providers.
    ‍
  • Good signal coverage for job changes, funding, website visits, and social activity.
    ‍
  • Excellent account research using Claygent to find specific company information.
    ‍
  • Strong outreach options with a built-in email sequencer and integrations with other sending tools.

Cons of Clay

  • More setup work when building custom signals with multiple conditions.
    ‍
  • Variable credit costs depending on the data providers and AI models used.
    ‍
  • Limited signal tracking on the Free plan, with job-change tracking starting on Launch.
    ‍
  • Higher plan required for web intent, which is available on Growth and above.
    ‍
  • Expensive for basic prospecting if you only need standard buying signals and contact enrichment.

Clay Pricing

Clay separates usage into Actions and Data Credits. Actions cover enrichment and GTM workflow usage, while Data Credits are used to buy data and AI from providers in Clay’s marketplace.

  • Free: $0/month with 500 Actions and 100 Data Credits.
    ‍
  • Launch: $185/month with 15,000 Actions and 2,500 Data Credits.
    ‍
  • Growth: $495/month with 40,000 Actions and 6,000 Data Credits.
    ‍
  • Enterprise: Custom pricing with 100,000+ Data Credits and 200,000+ Actions per month.
    ‍
  • Annual billing: Save 10%.

There is a lot more you can build with Clay, but that also means more setup and a higher starting price once you move beyond the Free plan.

4. 6sense

6sense homepage
This image shows the 6sense homepage

6sense is built around account-level buying intent. It tracks research activity across B2B publisher sites and intent sources such as G2, TrustRadius, Bombora, PeerSpot, and Gartner.

It combines that activity with website, CRM, company, and contact data to identify in-market accounts. Its predictive models then assign ICP fit, buying stage, and persona engagement, so you can see which accounts deserve attention and who within the buying group is involved.

6sense also provides company and people search, verified business emails, direct-dial numbers, sales alerts, and workflows for acting on these accounts.

Why 6sense Is a Good SyncGTM Alternative

6sense makes more sense if you already have a target account list and need to decide which accounts sales should work first.

Centralize intent data in one platform
This image shows the Centralize intent data in one platform

It can take intent activity, CRM history, website activity, and other account signals and turn them into an ICP fit, buying stage, and persona engagement for each account. Sales can then see which accounts are in-market, how far they may be into the buying process, and which members of the buying group are active.

That is a different use case from SyncGTM, where you can source prospects and build workflows around signals such as funding, headcount growth, job openings, tech-stack changes, job changes, and promotions. 

So, 6sense is the better fit if account prioritization comes before prospecting in your outbound process.

Pros of 6sense

  • Excellent buyer intent data from B2B research activity and third-party intent sources.
    ‍
  • Strong buying-stage predictions help identify accounts that may be closer to purchasing.
    ‍
  • Good account prioritization using ICP fit, buying intent, and account engagement.
    ‍
  • Large B2B database with verified business emails, direct-dial numbers, and company profiles.
    ‍
  • Strong sales integrations provide account insights inside CRMs, sales engagement platforms, and Chrome.

Cons of 6sense

  • No public pricing makes it difficult to compare costs before contacting sales.
    ‍
  • Credit-based contact access means data credits are used when unlocking contact information.
    ‍
  • More than basic prospecting if you only need contacts based on simple company or person signals.
    ‍
  • Predictive features need more account data because 6sense combines CRM, first-party, intent, and other account signals to produce its predictions.

6sense Pricing

6sense does not publish fixed monthly prices. You need to contact sales for a quote. It offers three Sales Intelligence configurations:

  • Sales Intelligence + Data Credits: Contact discovery, list building, third-party intent data, and contact enrichment.
    ‍
  • Sales Intelligence + Predictive AI: Buying-stage predictions, account scoring, and AI-recommended actions.
    ‍
  • Sales Intelligence + Data Credits + Predictive AI: Combines contact data access with predictive scoring and sales recommendations.

Data credits are used to unlock and export emails, phone numbers, and enriched records. Credit allocations depend on your contract, and unused credits do not roll over between allocation periods. 

5. Apollo.io

Apollo homepage
This image shows the Apollo homepage

Apollo.io is a B2B sales intelligence platform with built-in outreach. Its database covers 240M+ contacts and 30M+ companies, which you can search by company and contact filters.

For buying signals, Apollo uses Bombora intent data to identify companies researching any of 15,000+ topics. It scores company-level intent as high (75-100) or medium (61-74) and shows how that activity has changed over time.

From those companies, you can find relevant contacts, access emails and phone numbers, and use 20+ data partners through waterfall enrichment to fill missing details. You can then add those prospects directly to Apollo sequences.

Why Apollo.io Is a Good SyncGTM Alternative

Apollo.io is a stronger option if you want to start with accounts already showing research intent and move straight into prospecting and outreach.

Buying intent filters on Apollo
This image shows the Buying intent filters on Apollo

Its Bombora data helps you find companies researching specific topics, then Apollo lets you open those accounts, find the right contacts, enrich missing details, and add them to a sequence from the same platform.

SyncGTM is broader around signal-based prospecting across events such as hiring, funding, job changes, and tech changes. Apollo is the better fit if you mainly want topic-level intent connected directly to contact data and built-in sales engagement.

Pros of Apollo.io

  • Strong buying intent coverage with 15,000+ Bombora intent topics for finding companies researching relevant subjects.
    ‍
  • Large prospect database with 240M+ contacts and 30M+ companies.
    ‍
  • Good data enrichment with 20+ partners available through waterfall enrichment.
    ‍
  • Strong outreach support because prospects can move directly into Apollo sequences.

Cons of Apollo.io

  • Limited intent visibility because buying intent is measured at the company level, not the individual researcher level.
    ‍
  • Low intent topic limits with only 1 topic on Free, 6 on Basic and Professional, and 12 on Organization.
    ‍
  • Credit-heavy contact data because verified emails, phone numbers, and enrichment consume credits.
    ‍
  • Expensive for larger groups because paid plans are priced per seat, with Organization requiring at least three seats.

Apollo.io Pricing

Apollo pricing
This image shows the Apollo pricing
  • Free - $0: 75 credits per seat/month and 1 intent topic.
    ‍
  • Basic - $65/user/month: 2,500 credits per seat/month and 6 intent topics.
    ‍
  • Professional - $99/user/month: 4,000 credits per seat/month and 6 intent topics.
    ‍
  • Organization - $149/user/month: 6,000 credits per seat/month and 12 intent topics. Requires at least 3 users and annual billing.

Apollo is the more practical choice here if Bombora intent is enough for your use case and you also want prospect data and outreach without adding another tool.

Which SyncGTM Alternative Should You Choose?

There is no direct replacement here because each tool takes buying signals in a different direction. The choice comes down to how you want to find the opportunity and what you want to do with it next.

Tool Choose It When Skip It When
Leadsforge You want to turn funding, hiring, job changes, acquisitions, or investor activity into enriched prospect lists. You want multi-step GTM workflow automation inside the same tool.
Bitscale One signal is not enough and you want to stack several triggers before adding an account to your list. You only need basic signal-based prospecting and do not need its $349/month starting plan.
Clay Your buying signal depends on very specific data or research that you want to define yourself. You only need standard buying signals and contact enrichment and do not need custom signal workflows.
6sense You already have target accounts and want to rank them using intent, buying stage, ICP fit, and engagement. Your main job is finding new prospects from individual events.
Apollo.io You want Bombora research intent connected to contact data and sequences in the same product. Your prospecting depends more on event-based signals such as funding, acquisitions, or hiring than Bombora research intent.

Conclusion

SyncGTM is not short on buying signals or workflow features. The question is whether you need all of them for the way you prospect.

The five alternatives in this list solve that differently. Bitscale is useful when you want to stack several signals. Clay gives you more freedom to create your own. 6sense is geared toward identifying and prioritizing in-market accounts, while Apollo connects Bombora intent with prospect data and outreach.

Leadsforge is the simpler choice if your goal is to find prospects when a relevant buying event happens and get their contact details. You can search by funding, hiring, job changes, acquisitions, and investor activity, then enrich the prospects you want to contact through 20+ data providers. 

And at $49/month for 2,000 credits, you get twice the starting credits of SyncGTM's $49/month Solo plan. 

If prospecting and contact enrichment are the parts of SyncGTM you need most, try Leadsforge and build your first list from buying signals.
