10 Best Kaspr Alternatives & Competitors [2026]

Kaspr is a sales intelligence platform that automatically retrieves contact details on LinkedIn with its Chrome Extension.

The platform promises to help you enrich prospect data, create LinkedIn outreach campaigns, and integrate with all your sales tools.

However, some teams have been dissatisfied with the platform for various reasons, which is why they have been looking for competitors on the market.

In this buyer guide, I’ll go over the 10 best alternatives to Kaspr in 2026 that can help you build and refine your best lead list and then orchestrate outreach.

My selection criteria for this guide were not based solely on feature strength. I also considered the overall customer satisfaction, the different use cases of the tools, and their pricing models.

TL;DR

Warmly offers the best alternative to Kaspr by delivering verified, multi-source enriched data (so nothing is outdated or incomplete), eliminating credit burn with flexible component-based pricing, and providing far more accurate phone and intent signals through its 20+ provider waterfall engine.
Tools like Apollo and Lusha are ideal for teams that want fast contact enrichment, prospect list building, and scalable outbound automation.
On the other hand, platforms like Seamless AI and UpLead can help you access verified B2B data, real-time enrichment, and reliable filters for building high-quality ICP-fit lead lists.

Why have some sales teams been looking to make the switch from Kaspr?

The main reasons why some teams have been looking to switch from Kaspr are its contact information that can be outdated or incomplete, how easy it is to burn through credits, and its poor phone number data.

But don’t get me wrong on this one, I’m not trying to say that Kaspr is a bad tool that you need to run away from.

In fact, many satisfied users are more than happy with its email finder, GDPR compliance, and unlimited free access to B2B emails.

However, there are a few cons that I found when I tested and researched the tool: ⤵️

#1: Contact information can be outdated or incomplete

Although Kaspr aims to make prospecting easy with quick data enrichment, several reviewers highlight that the contact information delivered isn’t always reliable.

The issue here is that inaccurate or incomplete profiles may force teams to verify details manually, adding extra work and reducing the overall efficiency gains the platform promises.

‘’On top of that, the contact info can sometimes be outdated or incomplete, which is a huge pain.’’ – G2 Review.

#2: Burning through credits is too easy

Kaspr’s credit-based model creates friction for customers who rely on consistent, high-volume lead generation.

If your team is doing high-volume prospecting, the credit bucket feels like it drains too fast.

Instead of “use as needed,” the workflow becomes “save credits,” which slows reps down.

‘’Having to earn credits can be annoying when trying to find leads.’’ – G2 Review.

#3: Poor phone number data

While Kaspr provides phone number enrichment as a core feature, multiple reviews point to a lack of accuracy in this area.

Customers of the tool report that most numbers surfaced are personal or unrelated to the contact, with very little value for professional outreach.

‘’The majority, 90% of phone numbers, were personal home numbers (not cool) or registered to other people. <10% had business phone numbers for business contacts and no direct numbers.’’ – G2 Review.

#1: Warmly

Warmly offers the best Kaspr alternative with our AI Marketing Ops Agent that lets you automatically build, score, and continuously sync high-value, intent-driven audiences across CRMs, ad platforms, and outbound tools.

The platform removes manual list-building and fragile spreadsheet workflows by continuously discovering, enriching, scoring, and syncing the exact audiences you should be targeting right now.

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

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

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

Warmly’s AI Marketing Ops Agent lets you automatically build, enrich, score, and sync dynamic target audiences across CRM, ad platforms, and outbound tools.

Instead of manually exporting lists, cleaning data, or waiting for new leads, your team will get an always-fresh, AI-curated list of best-fit accounts and contacts synced across every system.

We noticed how sales teams spend a lot of time building, cleaning, and syncing target lists across CRMs, ad platforms, and outbound tools.

In fact, data shows that sales reps spend only ~28–33% of their time on actual selling, and administrative and non-selling work consumes most of their time.

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

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.

➡️ This helps our users catch up on in-market prospects doing research, as 96% of prospects research companies before engaging sales, according to research from HubSpot.

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, like Kaspr, give you firmographic filters, such as industry, headcount, location, and job title, and call it a day.

However, our software 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 users 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 site 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.

💡 Data shows that sales intelligence (enriched contact and intent data) can help shorten prospect-research cycles from 3–5 hours to 10–15 minutes, according to a recent industry research, as AI enrichment condenses discovery.

Warmly optimizes its data through a waterfall approach.

Our tool 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.

Feature #5: Build targeted lead lists from a 200M+ contact database (Coldly)

Similar to Kaspr, Warmly comes with a built-in prospecting platform, Coldly, which gives your team access to a constantly refreshed database of over 200 million contacts and accounts, so you can build high-quality prospect lists in seconds.

Our database combines powerful filters with real-time enrichment to help you find exactly who you’re looking for across every channel.

Your team will be able to filter by:

Job title, function, or department.
Seniority level and decision-making role.
Company size, revenue, industry, or location.
Tech stack and hiring signals.
And dozens more customizable filters.

➡️ Each lead comes pre-enriched with verified email addresses, phone numbers, and LinkedIn profiles, so your lists are not only accurate but immediately actionable.

Bonus: There’s also a Chrome extension that lets your reps pull contact data directly from LinkedIn or any website, making manual prospecting a whole lot faster.

Warmly’s Integrations

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

HubSpot CRM.
OpenAI.
Slack.

💡 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.

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:

Signals Agent: Custom pricing, which gives you access to 10,000 monthly credits, Person-Level Intent Signals (1st, 2nd, & 3rd Party), website de-anonymization capabilities, Warm lead alerts, and access to a contact database.
Inbound Agent - Engage: Starts at $20,000/year, and adds AI Chat, native outbound email and LinkedIn automation, intent-powered pop-ups, lead routing with custom CRM fields, and the ability to push leads to sales sequencers.

Marketing Ops Agent: Custom pricing, which adds AI-powered account scoring, AI enrichments and custom signals, buying committee identification, real-time buying intent signal tracking, and automatic updates across all enrichments, signals, account and lead lists.

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 Kaspr?

Kaspr is known for contact extraction and basic enrichment. The platform is useful for pulling emails and phone numbers from LinkedIn and quickly building simple prospect lists.

Warmly goes far beyond traditional contact finders by combining visitor identification, intent scoring, automated list building, and AI-driven outreach into one signal-powered revenue orchestration engine.

Warmly helps GTM teams replace manual prospecting tasks with agents that automatically surface high-intent buyers and activate outreach when it matters most.

Here is a breakdown of the two solutions' functionality:
