The most reliable AI powered sales assistant for B2B
Cognism is built for modern revenue teams that demand accuracy, compliance, and speed. Its AI sales assistant combines verified B2B contact data, real-time buyer signals, and automated outreach sequences to deliver results you can trust.
Unlike ZoomInfo or Clay, Cognism doesn’t just hand you data; it delivers GDPR- and CCPA-compliant, phone-verified leads enriched with the insights you need to start relevant conversations immediately.
Every feature is designed to improve your experience, not overwhelm you with alerts that lack context. At Cognism, we believe that trust, accuracy, and governance are the foundations for true prospecting efficiency, and that’s what you get with Sales Companion.
Sales Companion: AI-powered prospecting co-pilot that overlays insights directly into LinkedIn and company websites. It combines phone-verified data, live signals, and account recommendations to keep outreach fast, fresh, and compliant.
AI Search: Find prospects instantly with natural language or voice prompts. AI Search filters millions of records in seconds, delivering GDPR/CCPA-compliant leads enriched with Diamond Data®.
Smart Personas: Skip manual filtering. Describe your business and what you sell, Cortex AI auto-translates this into job titles, industries, geographies, and segments. It also recommends intent topics and technographics based on your model, so outreach stays hyper-targeted.
Research by Cortex AI: One-click company research built directly into Sales Companion. Pre-engineered prompts surface insights on revenue drivers, strategy, competitors, and ice-breakers, no messy prompt writing, no tab-hopping, just the right intel when you need it.

A powerful tool, but comes with extra costs.
ZoomInfo is one of the most recognised names in sales intelligence, but how does its AI Copilot compare to the rest?
The ZoomInfo Copilot offers a custom feed for each user with real-time alerts on account, contact and intent changes. It also includes an email writer for tailored emails based on buying groups and personas.
And, the ZoomInfo Copilot cost?
It’s an additional per-seat charge to existing ZoomInfo licenses.
ZoomInfo pricing must be requested from the website and follows individual pricing tiers for sales, marketing, and recruitment. Seats, credits, and supplementary tools, like ZoomInfo AI, also affect cost.

Flexible data enrichment, but not a full sales assistant.
Clay AI has gained popularity for its waterfall data enrichment, allowing teams to connect multiple tools and build custom prospecting sequences. However, the lack of phone-verified data and heavy configuration are drawbacks, especially as an AI sales assistant.
Clay AI has five pricing tiers: Free, Starter, Explorer, Pro and Enterprise. Packages are based on credits with unlimited user seats.

Great for email coaching, but not a full assistant.
Lavender specialises in AI-powered email writing feedback, helping reps craft more effective messages.
It’s a strong complementary tool, but can’t replace a full sales assistant platform like Cognism. You’ll still need separate tools for data sourcing, intent, and automation.
Lavender AI offers four plans: Basic, Starter, Individual Pro and Team.
Lavender excels at AI-driven email personalisation and coaching. But it’s not a complete sales assistant; you’ll still need a separate solution for prospecting, enrichment, and triggers.
Cognism is the best AI sales tool as it delivers all of these in one.
Strong in AI calling, but lacks prospecting tools.
Dialpad’s AI excels in transcribing and analysing calls, making it a good fit for call-heavy sales teams.
However, without integrated prospecting and lead generation, it’s not a complete AI sales assistant solution.
Dialpad offers three packages: Standard, Pro and Enterpise.
Dialpad’s AI is great for call transcription and coaching, but it doesn’t generate net-new pipeline.
Sales Companion helps drive conversations and ensures your team is talking to the right people at the right time.
Niche AI lead enrichment.
Breeze Intelligence is best suited for marketing and operations teams looking to enhance existing data and automate workflows.
This AI powered sales assitant focuses on AI-driven lead sourcing. Leveraging your CRM data to research companies, prep for sales calls, build pipeline and summarise CRM records for streamlined marketing and sales efforts.
Breeze Intelligence pricing is based on credit packs of 100, 1,000 and 10,000. Packs range from $30 to $700 a month.
Breeze Intelligence is focused on inbound data enrichment rather than outbound prospecting, and advanced features are only available on higher-tier HubSpot plans. What's more, due to the way pricing is set up, costs can increase significantly as your CRM grows.
Cognism offers real-time data signals and tech install data with unrestricted views/ individual and page-level exporting on all packages. This is subject to a generous fair usage policy.
While both providers have many integrations with other sales tools, such as Salesforce or HubSpot, Breeze Intelligence doesn’t offer integration with LinkedIn. Sales Companion is designed for sales reps’ workflows, including prospecting on LinkedIn.

Every AI powered sales assistant software offers features that promise better team performance, a streamlined sales process, and faster prospecting.
But, how can you be sure the tool you choose really lives up to those promises?
Here’s what to look out for when evaluating AI sales assistants:
You want a tool that takes compliance seriously. Why?
Well, not only can failure to comply with data laws result in fines, but reaching out to prospects on DNC lists can ruin your brand reputation. The last thing you want is potential buyers to avoid your brand because your sales calls are a nuisance.
Basic automation tools follow rigid, pre-set rules, for example, sending the same email sequence to every lead after a fixed number of days.
While that may save time, it ignores important factors like buyer intent, engagement signals, and sales cycle stage.
A context-aware AI sales assistant goes beyond these static workflows.
It analyses real-time data from multiple sources, including CRM updates, email opens, call transcripts, and buyer signals. This way, it can recommend or execute the next best action for each specific prospect.
For instance, instead of sending a generic follow-up, it might:
This type of AI doesn’t just automate tasks; it helps reps make smarter, better-timed moves, improving engagement rates and closing more deals.
AI sales assistants should be easy to use.
What’s the point of investing in a tool that’s supposed to make your reps’ lives easier when it’s hard to set up, has a strong learning curve, and doesn’t work half the time?
If you’re prospecting into new markets or looking to scale in different regions, your AI lead generation tool should align with those goals.
This means complying with international privacy laws, showing time zone differences, and filling your contact database with fresh and accurate data.
Seamless CRM and sales engagement platform compatibility are essential for B2B businesses.
The best AI agents can integrate with tools your team uses daily without interrupting or changing your workflows.
