7 Best B2B Data Chrome Extensions in 2025
Prospecting is broken when reps spend most of their week doing anything but selling. Sales reps now spend roughly 70% of their time on non-selling tasks – so tools that surface verified data in-context and cut clicks aren’t “nice to have,” they’re pipeline multipliers.
If you prospect on LinkedIn or company sites, the right Chrome extension turns browsing into a pipeline: reveal verified emails and phones, see firmographics and technographics in context, and push prospects straight into your CRM with minimal clicks.
Here’s a clean, comparison-first guide to seven standouts:

| AddToCRM | 1-click sync from LinkedIn, Gmail and outlook to your CRM | Verified emails/phones; duplicate awareness; very wide CRM coverage. |
| ZoomInfo (ReachOut) | Enterprise intelligence at scale | Direct dials; company intel; wide integrations from the extension. |

1. Apollo.io
Apollo blends a large B2B database with in-workflow outreach: capture from LinkedIn and across the web, add to lists and sequences, and work from Gmail, calendar, and CRM. Public listings cite access to 210M contacts and 35M accounts, with the extension included on the free tier. Beyond discovery, Apollo shortens the gap to first touch with built-in sequencing, a dialer, and robust filtering – so reps can research, enrich, and engage without leaving their tab. It’s a strong “single pane” for teams that want fewer tools and faster motions.
Where it shines
- Data discovery and engagement live in one place, reducing context switching
- The extension works across LinkedIn, Gmail, Google Calendar, your CRM and company sites.
Watch-outs
- Export limits and credit mechanics apply by plan; review tiers before rolling out broadly.
2. AddToCRM.com
Built to “kill copy-paste”, Add to CRM is a chrome extension which lets you sync prospects from LinkedIn, Gmail and Outlook to your CRM. They offer a huge B2B database (220M prospects) and over 96% accuracy.
On a LinkedIn profile you can get access to verified contact info (e.g. email, phone etc) and also see if the person already exists. Otherwise you can add the record to one of 26+ CRMs. Here is a full list of their LinkedIn CRM Integrations.
Where it shines
- Fastest prospect-to-CRM handoff with duplicate awareness and one-click add.
- The broadest CRM coverage of any extension with dedicated extensions for 26+ CRMs.
- Highly accurate data
Watch-outs
- Purpose-built for capture and CRM hygiene; pair with your sequencer or dialer for full outreach.
ZoomInfo (ReachOut)
The ReachOut extension overlays contact and company data wherever you browse and lets you export directly to CRM and sales engagement tools. It’s included for subscribers and is designed for deep research and action from LinkedIn, Salesforce, and company sites. ReachOut brings org charts, direct dials, buying signals, and rich firmographics into the page you’re on, so researchers and sellers can qualify accounts and trigger next steps without switching systems. It’s built for scale, governance, and complex team workflows.
Where it shines
- Depth: direct dials, rich firmographics, and workflows that plug into existing systems.
- Enterprise rollouts with mature integrations and governance.
Watch-outs
- Pricing is contract-based; ensure credit usage and user seats match expected volume.
Lusha
Known for quick reveals on LinkedIn, Lusha has expanded its dataset and automation while keeping an easy, freemium-friendly credit model. Its pricing page lists a free plan with monthly credits. The extension excels at surfacing verified emails and mobile numbers fast, helping SDRs move from profile view to outreach in seconds. Setup is minimal, exports are straightforward, and the workflow pairs neatly with any existing sequencer or dialer.
Where it shines
- Speed and simplicity for sellers who need verified emails and mobile numbers.
- Low-friction rollout; credits keep costs predictable at small scale.
Watch-outs
- If you want sequences, intent, or advanced analytics in the same UI, pair it with your engagement platform.
Ampliz (SalesBuddy)
SalesBuddy focuses on prioritization. Set your ICP and get a prospect fit score, then reveal contact details and see context like technographics and funding to guide who you contact first. The extension is designed to help reps work smarter than a simple “reveal” – highlighting the right targets and enriching them in one place. With credit-based plans (including free credits to try), it’s an easy way to add scoring and enrichment without overhauling your stack.
Where it shines
- Prospect fit score available on all plans helps reps focus on the highest-fit leads
- Easy, credit-based entry with free credits to try before scaling.
Watch-outs
- Credit packs require simple usage forecasting; avoid running dry mid-campaign.
Cognism
Cognism’s extension surfaces business emails and DNC-screened mobile numbers, with accuracy reinforced by its phone-verified Diamond Data. Documentation highlights extension support for LinkedIn and Sales Navigator. It’s oriented toward call-heavy teams that need reliable mobiles and strong compliance guardrails – capture a profile, sync it to your CRM or engagement tool, and start dialing with higher confidence. Expect an emphasis on data quality and governance alongside productivity.
Where it shines
- Phone-verified mobile numbers to increase connect rates.
- Compliance posture and DNC checks are a core part of the offer.
Watch-outs

Support docs emphasize real-time querying and status feedback during capture. LeadIQ is ideal for fast list building from Sales Navigator: select, capture, and push to your sequences with minimal manual entry. The real-time approach helps keep data fresher, while the extension’s bulk-friendly UI keeps reps in flow.
Where it shines
- Rapid list building from LinkedIn search pages with one-click capture and instant sync.
- Real-time approach helps avoid stale data and reduces manual entry.
Watch-outs
- On-demand discovery can vary by contact; have a backup data source for edge cases.
Conclusion
Choosing the right B2B data extension is less about flashy features and more about fit. If you want one platform for data and outreach, Apollo is hard to beat. If your day lives inside the CRM, AddToCRM gives you the fastest LinkedIn-to-CRM flow. ZoomInfo brings enterprise depth, Lusha and LeadIQ win on speed, Ampliz helps you prioritize with fit scoring, and Cognism leans into phone-verified accuracy.
Run a 30-day pilot with two contenders and make the call on outcomes, not opinions: improve verified reachability, cut time to first touch, reduce duplicates, and lift meetings per 100 reveals. If the numbers move, you’ve found your stack.
