10 Best Success AI Alternatives & Competitors [2026]

Success AI uses AI to help you send unlimited emails to verified leads and scale your outreach.

The platform promises to help you identify the right leads to target, personalize the emails, and track the results of your campaigns.

However, some sales teams have been dissatisfied with the solution for various reasons, which is why they have been seeking an alternative.

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

My selection criteria are not based solely on feature strength; I also took into consideration overall customer satisfaction, the different use cases of the solutions, and their pricing models.

TL;DR

Warmly offers the best alternative to Success AI with its signal-based revenue orchestration, AI Marketing Ops Agent, and real-time visitor identification capabilities that automatically build, score, and sync target audiences across your GTM systems.
Apollo and Seamless AI are ideal for teams that want large contact databases combined with built-in outreach automation, helping you handle prospecting and engagement in one place.
On the other hand, tools like Clay, MadKudu, and Cognism can help you automate enrichment, predict lead conversion, or access globally verified B2B data.

Why have some sales teams been considering a switch from Success AI?

The main reasons why some sales teams have been looking to switch from Success AI are its pricing model, which can be expensive for SMEs, its limited data customization capabilities, and its learning curve.

But don’t get me wrong, I’m not claiming that Success AI is a terrible product that needs to be switched from.

In fact, many satisfied users are happy with how much time the tool saves them on outreach, its simple interface, and email personalization features.

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

#1: Pricing can get expensive for SMEs

Starting off with Success AI’s pricing structure, some small business owners and agency founders feel like the platform can be expensive for SMEs.

The platform might look affordable at first, but it splits its pricing into Leads and Outreach, which means that you’ll have to invest a few hundred dollars a month to combine lead list building with automated outreach to get the results you need.

‘’Another concern is the pricing since many of my clients are small business owners, the cost can be a bit too high for them.’’ – G2 Review.

Another small business owner mentions that the platform has a per-user pricing model, which cannot be immediately seen from its pricing page; it can get expensive as you bring in more members to your team.

‘’The per-user pricing model can get a bit expensive as you add more members to your team.’’ – G2 Review.

#2: Limited data customization features

Next up, when users export lead data from Success AI, such as names, emails, company details, or engagement metrics, they can’t fully choose which fields or data points to include or exclude.

This means users who need specific or custom data for their workflows (e.g., CRM imports or segmentation) can’t easily tailor the export to match their requirements.

‘’One thing I'd like to see improved is more flexibility in customizing the lead data fields when exporting. Sometimes I need specific information, and while the current data is great, a bit more customization would make it even better.’’ – G2 Review.

#3: Initial learning curve

Last but not least, there are many instances of dissatisfied users with Success AI’s initial learning curve.

A user of the tool mentions that the platform can be complex when setting up certain features for the first time.

‘’Success.ai can have a bit of a learning curve, especially when setting up certain features for the first time. The AI-generated emails are helpful but often need a human touch to make them truly personalized.’’ – G2 Review.

#1: Warmly

Warmly offers the best Success AI alternative on the market in 2026 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 solves the headache of manual list-building, stale segments, and one-off uploads by keeping target lists fresh in real-time.

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

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

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

Warmly’s new AI Marketing Ops Agent transforms how sales teams manage and activate audiences.

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 GTM teams spend enormous 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.

The tool 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.

➡️ This helps our customers 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 platforms on the market, like Success AI, 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.

💡 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 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.

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

Similar to Success AI, Warmly offers 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 prospect 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.
Apollo.
Outreach.
Demandbase.
RB2B.
Clearbit.
People Data Labs.
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:

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.
Inbound Agent - Scale: Starts at $30,000/year, and adds unlimited AI Chat agents, and the ability to push leads to Ad Audiences.
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 Success AI?

Success AI is a B2B lead generation and outreach platform with a large verified contact database, data enrichment, and built-in sending tools for scaled outbound campaigns.

Warmly, on the other hand, is a signal-based revenue orchestration platform that identifies anonymous website visitors, enriches them in real-time, and offers an AI-powered Marketing Ops Agent that automatically builds, scores, and syncs target audiences across all your GTM systems.

➡️ Our tool offers a better solution for teams that want to eliminate manual list management, automatically identify in-market accounts, and activate outreach instantly.

Here is a breakdown of the two solutions' functionality:

Category	Warmly	Success AI
Core Functionality	Real-time website visitor de-anonymization, person & account-level identification, and signal-based revenue orchestration. The Marketing Ops Agent auto-builds and refreshes target lists based on live buying signals.	Large B2B contact database (700M+) with lead discovery and campaign tools for creating and sending sequences. Focused on list discovery/export and outbound campaign execution.
Data Enrichment & Intent Signals	Combines first-, second-, and third-party signals (site behavior, repeat visits, competitor research) with multi-source enrichment. The Agent continuously re-scores contacts by fit and intent.	Strong enrichment and verification of contact data (emails, phones, firmographics). Intent is primarily based on data filters and campaign engagement rather than live behavioral signals.
Automation & Outreach	The Marketing Ops Agent automates audience building, scoring, and syncing to CRMs, ad platforms, and outbound tools — enabling near-instant campaign activation without manual list uploads. Also supports AI-driven outreach across channels.	Provides multichannel outreach automation, inbox management, and deliverability tools. Optimized for outbound sequencing rather than real-time audience orchestration.
Integrations & Syncing	Automatically syncs audiences with HubSpot, Marketo, LinkedIn, Meta, Outreach, and other GTM tools. Removes the need for manual list management.	Integrates with CRMs and outreach tools to manage contact imports and exports for outbound campaigns.
Best For	GTM, RevOps, and marketing teams that want to identify in-market visitors, auto-maintain dynamic audiences, and activate personalized outreach instantly without manual operations.	Sales and growth teams that need a large, verified contact database to power outbound campaigns and manage deliverability at scale.

#2: Apollo
