13 Best B2B Sales Intelligence Tools and Companies (2026)

Sales intelligence is a broad label. Some tools sell contact data, some sell account intent, some deliver dated signals, and some run the outreach itself. This guide sorts 13 tools into those four groups, so you compare like with like. The comparison table at the top of this page lists every tool by best fit, data type, delivery and pricing model, with a source link for each vendor fact.

If you buy data by API rather than by seat, also read our comparison of the best data enrichment APIs and the B2B data providers guide.

What is B2B sales intelligence?

B2B sales intelligence is the data and tooling that tells a sales team who to sell to, when to reach out and what to say. It feeds the CRM; it does not replace it. The products in this category answer four different questions:

Category	Question it answers	Examples in this guide
Contact data	Who should we reach, and how?	ZoomInfo, Apollo, Cognism, Lead411
Intent and account data	Which accounts research our category?	6sense, Demandbase, Bombora
Signal data	What just changed at the account?	Autobound, UserGems
Engagement and execution	How do we run the outreach?	LinkedIn Sales Navigator, Outreach, Salesloft, Artisan

Most teams buy from two or three of these categories. Know which one you shop in before you compare prices, because a contact database and a signal API are not substitutes.

How we compared these tools

We read each vendor's public product and pricing pages and recorded what the vendor itself states: the data it sells, how you get it and how it charges. Every vendor fact in the table links to the page it came from, with the date we read it. Where a vendor publishes no price, we say so instead of guessing.

• Data type: contacts, company records, intent, events or engagement data.
• Delivery: web app, CRM integration, API, MCP server or file delivery.
• Pricing model: seats, credits, exports, annual plans or quote only.
• Best fit: the team and use case the product is built for.

We did not run accuracy tests, so this page prints no accuracy or connect-rate numbers. Test your shortlist on a sample of your own CRM records before you sign. Autobound is one of the 13 tools, and our row uses our published pricing and Signal API facts.

Contact data platforms

1. ZoomInfo: broad contact and company data in one platform

ZoomInfo describes itself as an AI go-to-market platform for B2B sales, marketing, RevOps and customer success teams. It states 500M+ contacts and 100M+ companies, plus intent and behavioral signals, and it joins Chorus call data with CRM and intent data.

• Strong fit when: you want contacts, companies and intent from one vendor, inside one app your reps already use.
• Consider another tool when: you need only one data type by API, such as dated account events for an AI agent or a product.
• Pricing model: free to start, then consumption credits based on usage (ZoomInfo).

2. Apollo: contact data plus sequencing

Apollo combines a contact database with email sequencing, call recording and pipeline tools. Apollo states access to 240M contacts and 30M companies, and it integrates with Salesforce, HubSpot, Outreach and Salesloft.

• Strong fit when: you want contact data and email sequencing in one tool, and you want to start on a free plan.
• Consider another tool when: you need API access without a Custom plan, or you already run sequences in another engagement tool.
• Pricing model: a free Starter plan, paid plans by seat with credits, and Custom plans that include API access (Apollo).

See Apollo alternatives.

3. Cognism: contact data with a Europe focus

Cognism sells B2B contact data with phone-verified mobiles, a prospecting platform and CRM enrichment. Its plans list emails, mobiles, job titles, work history, revenue, headcount and technology usage, with intent data on the Pro plan.

• Strong fit when: you sell into Europe and need compliant contact data and mobile numbers.
• Consider another tool when: you need dated events, such as filings, hires and funding, rather than contact records.
• Pricing model: a seat subscription with 5 seats included and credits, where 1 credit reveals 1 contact (Cognism).

See Cognism alternatives.

4. Lead411: contact data billed by export

Lead411 sells verified emails and direct phone numbers. Its pricing page lists plans billed by exports, monthly or annually, and adds buyer intent data on annual plans.

• Strong fit when: a small team wants verified emails and direct dials with a month-to-month option.
• Consider another tool when: you need an API-first data feed for a product or a warehouse.
• Pricing model: Spark, Ignite and Blaze plans billed by exports, with a 7-day free trial (Lead411).

Intent and account platforms

5. 6sense: predictive account intelligence

6sense packages sales intelligence with data credits, predictive AI models, a Sales Copilot, company and contact insights and a Chrome extension. Teams use it to find and rank accounts that show buying behavior.

• Strong fit when: your team runs account-based programs and wants predictive account scores in one platform.
• Consider another tool when: you need raw, dated events by API to feed your own scoring or an AI agent.
• Pricing model: quote only. 6sense lists three Sales Intelligence packages without public prices.

6. Demandbase: ABM platform with account data

Demandbase is an ABM platform that turns account, buying-group, engagement and signal data into programs for sales and marketing teams.

• Strong fit when: sales and marketing run account-based programs together.
• Consider another tool when: you only need a data feed, not a program platform.
• Pricing model: a platform fee plus a flat fee per user, priced by quote (Demandbase).

7. Bombora: topic intent from a publisher co-op

Bombora Company Surge measures topic research across a co-op of B2B publisher sites and flags companies that research a topic more than usual. Many platforms deliver Bombora data through partner integrations.

• Strong fit when: you rank accounts by the topics they research and want intent inside the tools you already use.
• Consider another tool when: you need person-level contacts or dated events rather than topic research.
• Pricing model: no public price (Bombora).

Signal data platforms

8. Autobound Signal API: dated account and contact events by API

The Autobound Signal API returns dated, sourced events for a company domain or a contact: news, SEC filings, hiring changes, job changes, funding, posts, podcasts and more. One API covers every signal type, with search and enrich endpoints, an MCP server for AI assistants, and GCS or flat file delivery for a warehouse.

• Strong fit when: you already have contact data and need to know what changed at an account, in your CRM, your product or an AI agent.
• Consider another tool when: you need emails and phone numbers to dial. Autobound sells signals, not a contact database.
• Pricing model: credits per result, with self-serve credit packs and free credits on signup. Calls that return nothing are free. See pricing.

To enrich one company or one person, see the company enrichment API and the contact enrichment API. Platforms that embed signals in their own product license them through OEM data licensing.

9. UserGems: pipeline from job changes and relationships

UserGems sells AI agents that build lists, capture signals and write emails. Its best-known use is tracking past buyers and champions who change jobs, so a team can reach them at the new company.

• Strong fit when: you have a large base of past customers and champions and want pipeline from their job moves.
• Consider another tool when: you need many signal types as raw data for your own systems.
• Pricing model: annual plans (Core, Advanced, Elite) listed on the UserGems pricing page, from $40,000 a year for Core.

Engagement and execution tools

10. LinkedIn Sales Navigator: relationship selling on LinkedIn

LinkedIn Sales Navigator turns the LinkedIn network into a prospecting tool, with lead and account search, alerts, relationship paths and InMail.

• Strong fit when: account executives sell through relationships and need to map buying committees.
• Consider another tool when: you need verified emails or phone numbers, or bulk data for a system.
• Pricing model: per-seat plans (Core, Advanced, Advanced Plus), with a free trial for eligible members (LinkedIn).

11. Outreach: sales execution

Outreach runs sequences, calls and deal workflows. It is an execution layer, so most teams pair it with a contact or signal data source.

• Strong fit when: a sales team runs multi-step sequences and wants AI help inside them.
• Consider another tool when: you are shopping for the data itself.
• Pricing model: per-user seats plus consumption-based AI credits, priced by quote (Outreach).

12. Salesloft: revenue workflow

Salesloft combines cadences, conversation intelligence, deal management and forecasting in one workflow. Like Outreach, it needs a data source next to it.

• Strong fit when: you want engagement, deals and forecasting in one place.
• Consider another tool when: you are shopping for contact or signal data.
• Pricing model: no public prices; Salesloft prices by quote.

13. Artisan: an AI BDR with built-in data

Artisan sells Ava, an AI BDR that finds and enriches B2B leads, writes and sends personalized outreach, handles replies and books meetings.

• Strong fit when: a lean team wants an agent to run outbound end to end.
• Consider another tool when: your data team needs raw data by API or in a warehouse.
• Pricing model: not verified. We could not read a public price.

Alternatives to the top sales intelligence platforms

Looking for an alternative to one platform in particular? Each page below lists vendors from the same category, with sourced facts and a note on when the original is still the better choice:

• ZoomInfo alternatives: contact and enrichment vendors that replace parts of ZoomInfo.
• Apollo alternatives: contact data and enrichment API options.
• Cognism alternatives: contact data vendors with Europe coverage.
• Clearbit alternatives: enrichment for teams outside HubSpot.
• People Data Labs alternatives: person data by API.

For vendors that sell dated events, see signal data providers compared.

How to build your sales intelligence stack

Start from the job, not the vendor. A working stack has one source for who to reach, one source for when to reach them, and one tool to run the outreach. Join them on the company domain and the work email.

Stage	Who to reach	When to reach them	How to reach them
Startup (1 to 10 reps)	Apollo free or paid plan	LinkedIn Sales Navigator alerts, or Autobound free credits	Apollo sequences
Growth (10 to 50 reps)	Apollo, ZoomInfo or Cognism	Autobound Signal API or UserGems	Outreach or Salesloft
Enterprise (50+ reps)	ZoomInfo or Cognism	6sense, Demandbase or Bombora for intent, plus Autobound for dated events	Outreach or Salesloft

Common mistakes

1. Two tools for the same job. Two contact databases mostly return the same people. Buy a second source only to fill a gap you measured.
2. Data without timing. A contact list tells you who, not when. Add a signal source so reps reach out after something changed.
3. Data without workflow. Route each signal to an owner, a CRM task or an AI agent. A dashboard nobody opens does not create pipeline.
4. Enterprise contracts for small teams. Start on free plans and credits, and scale after you measure results.
