10 Best Leadspace Alternatives & Competitors [2026]

Leadspace identifies as a B2B customer data platform that unifies first-party and third-party data to create unified account and contact profiles and power ABM activation.

However, some teams have not been entirely happy with the solution for different reasons, which is why some of them have been looking for an alternative.

In this article, I’ll go over the 10 best alternatives to Leadspace in 2026 that can help you build your best lead list.

The way I selected them was not on feature strength alone: I took into consideration the overall user satisfaction, the different use cases of the solutions, and their pricing models.

TL;DR

Warmly offers the best alternative to Leadspace with its signal-based revenue orchestration, AI SDR automation, and real-time visitor identification capabilities.
Tools like Cognism and Apollo are ideal for teams that want accurate B2B contact data and built-in outbound automation for global prospecting.
On the other hand, there are tools like Demandbase and 6sense that can help you run full-funnel ABM campaigns and predict in-market accounts using advanced intent data.

Why are some sales teams looking to switch from Leadspace?

The main reasons why some sales teams have been looking to switch from Leadspace are its expensive pricing, its issues with lead-to-account matching, and its poor range of integrations.

But don’t get the wrong idea here, I’m not trying to claim that Leadspace is a bad product that you should run from.

In fact, there are many satisfied mid-market and enterprise users who are satisfied with the platform’s data, Revenue Radar, and overall value proposition.

Despite this, there are a few caveats that I found when I evaluated the tool: ⤵️

#1: Expensive entry-level pricing

The first thing you’ll notice about the platform is its high starting price when compared to other sales intelligence platforms, which I found from Capterra, which also does not feature a free version.

Some users of the platform do mention that the price is high for them, although they believe that it’s worth the cost in the end.

Despite this, I still think that this price tag is prohibitive for both SMEs and some mid-market companies, as Leadspace seems to cater more to enterprise clients.

‘’Price, but you do get what you pay for.’’ – G2 Review.

#2: Issues with lead-to-account matching

Next up, many users are not happy with the tool’s lead-to-account matching, which is the process of automatically linking individual leads (like form submissions or email contacts) to the correct company accounts in your CRM.

➡️ If it’s inaccurate, your reps will waste time on duplicate or misrouted leads, the pipeline visibility will suffer, and valuable opportunities can slip through the cracks.

‘’The lead-to-account matching isn’t perfect.’’ – G2 Review.

#3: Poor range of integrations

Last but not least, some users of the platform are not happy with Leadspace’s integrations, specifically with CRMs like HubSpot.

According to one verified mid-market reviewer, the tool’s integration experience leaves a lot of room for improvement.

‘’Their integration with platforms like HubSpot and their experience with it has a lot of room for improvement.’’ – G2 Review.

#1: Warmly

Warmly offers the best Leadspace alternative on the market in 2026 with our signal-based revenue orchestration tool that lets you identify your website visitors at the person and account level and then automatically reach out to them.

With built-in AI SDRs and Marketing Ops automation that push personalized outreach straight into CRMs and outbound channels, our platform helps GTM teams convert live intent into pipeline faster than a traditional CDP-first solution.

Disclosure: Even though Warmly is our AI sales software, I’ll provide an unbiased perspective on why Warmly is the best alternative to Leadspace in 2026.

Warmly offers a signal-based revenue orchestration solution that lets you:

Identify website visitors (~60% of companies and ~15% of contacts).
Reveal which website visitors are most likely to convert.
Gain unique insights into prospects so that your SDRs can tailor their strategies accordingly.

Let’s look at some of the capabilities that make Warmly the go-to option for sales teams looking to switch from Leadspace:

Feature #1: Automate list building and enrichment with the Marketing Ops Agent

Our Marketing Ops Agent helps you build a real-time, auto-updating list of your best prospects.

We noticed that GTM teams spend enormous time building, cleaning, and syncing target lists across CRMs, ad platforms, and outbound tools.

The Marketing Ops Agent automates that, acting as a real-time intelligence layer between your data sources and your marketing & sales systems.

The solution automatically builds and maintains real-time, up-to-date lists of your best-fit accounts and contacts, so your team can focus on strategy and creativity instead of spreadsheets.

Here's how it works:

‎

The Marketing Ops Agent connects directly to your CRM, ad platforms, outbound tools, and intent sources to automate key targeting workflows:

AI-powered lead scoring and enrichment to create dynamic lists ranked by fit and buying intent.
Buying committee identification using insights from past closed-won deals.

Instant audience syncing with HubSpot, Marketo, LinkedIn, Meta, Outreach, and more. No more manual CSV uploads.
Automatic list updates as new intent signals or engagement changes occur.
Unified buying intent scores that stay synced across every sales and marketing channel.

Feature #2: Find prospects that look just like your best customers

Most sales intelligence tools on the market give you firmographic filters, such as industry, headcount, location, and job title, and call it a day.

However, our platform goes much deeper.

With our AI-powered ICP identification capabilities, Warmly analyzes your actual customer data to uncover what really makes a good fit.

And it’s not just surface-level attributes: it’s patterns across the company tech stack, growth signals, org structure, seniority distribution, and even past engagement behavior.

Once Warmly understands who your best customers truly are, it’ll automatically scan its database of 200M+ contacts to find lookalike prospects, that is, the people and companies that closely resemble your top performers.

The result is a list of not just any prospects, but the right prospects, so your team spends less time guessing and more time engaging the people most likely to convert.

Feature #3: Identify your website visitors at the company and person level

Warmly helps you maximize your website’s lead generation potential by identifying both the companies and individuals visiting it.

All you have to do is add a snippet of Warmly’s code to your site, and the sales intelligence software will start revealing your visitors in minutes.

In addition to company and person-level identification, Warmly will also enrich your visitors’:

Contact data (e.g., email address, phone number, social media profiles, etc.).
Firmographics (e.g., company location, size, funding, etc.).
Demographics (e.g., individual names, job positions, etc.).
Technographics (e.g., tools a prospect uses).

But our visitor identification solution doesn’t stop there.

Warmly also tracks real-time 1st, 2nd, and 3rd-party intent signals to surface the visitors that matter most, so you can instantly prioritize outreach based on actual buying behavior.

That includes:

1st-party signals, such as pricing page views, repeated visits, product usage, or form fills.
2nd-party signals like relevant LinkedIn activity (e.g., industry-relevant discussions, posts, comments, likes, etc.).
3rd-party signals like competitor research or intent keywords being searched.

Warmly optimizes its data through a waterfall approach.

Our platform uses multiple data providers (20+), including 2 other leading website de-anonymization providers, to validate the accuracy, quality & overall match rate of our signal & contact data.

We’ve seen that this leads to:

Higher data quantity: Multiple sources expand match rates.
Higher data quality: Proprietary cleansing and confidence scoring validate accuracy.

💡 To maintain data quality and quantity, we continuously monitor vendor performance and validate our proprietary matching algorithms.

➡️ These systems allow us to track quality and quantity metrics in real-time to make sure that both contact-level and company-level data meet the high standards our customers expect.

Warmly’s transparent data commitment means you can test our data quality with our free tier before committing to us as a data provider.

Since our platform aggregates data from 25+ providers and cross-checks it using our proprietary waterfall technique, the software can validate and verify data on your behalf, ensuring it’s of the highest quality.

Feature #4: Turn static lead lists into automated outreach with AI SDRs

Once you have built the list of prospects, Warmly doesn’t just let it sit there. It gets to work for you.

With AI Orchestrator and built-in AI SDR agents, our platform turns every ICP-fit prospect into a warm opportunity by triggering automated, personalized outbound across email and LinkedIn, based on real-time behavior and intent signals.

Here’s how it works:

Prospects who match your ICP and show strong signals (like visiting the pricing page or researching competitors) are instantly added to outbound sequences.
Messages are tailored automatically using contact data, context, and intent.

3. Warmly checks to avoid duplicate outreach and ensures contacts aren’t already being worked.

4. It’s also possible to set rules for account multithreading, so your AI SDR reaches all the key decision-makers, not just one person.

And this isn’t just task automation. It’s real prospecting, at scale, without increasing SDR headcount.

Warmly’s Integrations

Unlike Leadspace, Warmly integrates with a wide range of CRMs and sales platforms, including:

HubSpot CRM.
OpenAI.
Slack.
Apollo.
Outreach.
Demandbase.
RB2B.

And more.

💡 For example, you can combine Warmly’s visitor identification software with HubSpot to alert your sales team the moment a known prospect arrives on the site.

With the HubSpot browser cookie, you can prioritize conversations with the leads who have shown the most engagement with your HubSpot campaigns.

In addition to deep integrations with several lead intelligence platforms, Warmly provides a Warm Bundle: partner discounts for over 25 sales, marketing, and GTM tools.

This way, your team can access many relevant tools and combine them with Warmly at a fraction of their usual price.

Pricing

Warmly’s pricing is modular and component-based and comes with a free plan that lets you identify up to 500 website visitors per month.

You can choose the components that best match the needs of your business, as components are priced by output and not just by a monthly fee.

There are 4 paid product plans that you can choose from:

AI Data Agent (Starts at $10,000/yr), which includes 10,000 credits, person-level web visitor de-anonymization (RB2B + Vector data), CRM integration, and access to our Coldly Contact Database.

Monthly credits on Warmly are used to track and engage with potential leads.

For example, each interaction or engagement with a lead will use up one credit, such as when you engage with a lead through email or LinkedIn.

➡️ Warmly’s pricing is ideal for larger SMB and MM companies with a growing or mature GTM motion with SDR, sales, and marketing functions.

How do Warmly’s credits work?

💡 Warmly provides you with a certain amount of credits every month, depending on your monthly web visits and the amount you want to de-anonymize.

Once someone visits your website, the tool captures their first and last name, job title and company they work at, LinkedIn profile and business or personal email. This information takes 1 credit.

For example, each interaction or engagement with a lead will use up one credit, such as when you engage with a lead through email or LinkedIn.

How is Warmly different from Leadspace?

Leadspace is a B2B customer data platform that unifies first- and third-party data, enriches profiles, and applies predictive scoring and ICP models to feed downstream martech systems.

Warmly, on the other hand, is a signal-based revenue orchestration platform that de-anonymizes website visitors at the person and account level and immediately turns high-intent visitors into personalized outreach using built-in AI SDRs and Marketing Ops automation.

➡️ Warmly offers a better solution of Leadspace for sales teams that need to instantly identify in-market visitors, automatically build and maintain target audiences, and push those audiences everywhere without spreadsheets.

Here is a breakdown of the two solutions' functionality:

Category	Warmly	Leadspace
Core Functionality	Visitor de-anonymization and signal-based revenue orchestration that identifies people & accounts visiting your site and prioritizes them for outreach.	Enterprise B2B customer data platform that consolidates account & contact data, builds unified profiles and supports predictive modelling.
Data Enrichment and Intent Signals	Real-time 1st/2nd/3rd-party intent tracking (pricing page views, repeat visits, LinkedIn activity, competitor searches) plus multi-vendor waterfall enrichment from 20–25+ providers for higher match rates and contact-level data.	Large-scale enrichment from many sources with firmographic data, buying centre and predictive propensity built from unified data.
Automation and Outreach	Built-in AI SDRs, automated personalized sequences across email, LinkedIn, and chat, Marketing Ops Agent for live list building and instant syncing to CRMs and ad platforms (HubSpot, Outreach, etc.).	Primarily operationalizes data and scores into downstream systems (MAP/CRM/ads) for campaign activation; less emphasis on autonomous outbound agents: the focus is on feeding and improving campaigns.
Best For	GTM and revenue teams that want visitor identification, outreach automation and autonomous, intent-driven prospecting at scale without expanding SDR headcount.	Enterprises and martech-heavy teams that need a centralized B2B CDP, advanced predictive models, and robust data hygiene to power personalized campaigns across channels.

Pros & Cons

✅ Identifies companies and individuals visiting your website.

✅ Enriches each identified lead with detailed B2B intelligence and reveals intent data.

✅ Identify buying committees.

✅ Live sales engagement capabilities.

✅ You can build a real-time, auto-updating list of your best prospects.

✅ Generous free plan to get started with 500 website visitors to de-anonymize.

❌ Pricing is modular.

#2: Cognism

Best for: Providing accurate and compliant B2B contact data, particularly for global outbound and phone-based prospecting.

Similar to: Apollo, Persana AI.

Cognism is a B2B sales intelligence platform that focuses on verified contact data and compliance, making it ideal for teams targeting prospects across EMEA, the US, and APAC.

The reason why I think that the platform is a viable Leadspace alternative is that it focuses on contact-level accuracy, direct-dial coverage, and GDPR-compliant enrichment.
