What Is B2B Data and Why It Matters for Modern Sales Teams

How to Evaluate B2B Data Vendors for Accuracy and Compliance
ReachStream Prospect vs Kaspr is really a choice between two starting points. Kaspr is built around revealing phone numbers and emails while you browse LinkedIn. ReachStream Prospect is a searchable database of 500M+ contacts and 50M+ companies with a LinkedIn extension attached. Either can feed a cold outreach workflow. They just get you there differently.
This comparison covers contact data, email finding, phone numbers, LinkedIn prospecting, enrichment, integrations, and pricing.
Contact data enrichment simply means adding missing details, such as emails, phone numbers or job titles, to records you already have. That is one piece of the puzzle. The areas where ReachStream Prospect vs Kaspr actually diverge are the data itself, how emails are found and checked, the LinkedIn workflow, and how each vendor counts credits.
Kaspr holds over 200 million European B2B contacts drawn from 120+ data sources, and it calls Europe home turf. Its data page also says it provides data for decision makers globally, so the emphasis is regional rather than exclusive. According to Kaspr, contact details are updated in real time whenever a user requests them.
ReachStream Prospect lists 500M+ contacts, 50M+ companies and 100M+ direct dials across 150+ countries, searchable by job title, seniority, industry, technology, revenue and location. Its records are checked by an AI-powered engine and human researchers, with 95% data accuracy.
Any verified contact data comparison only means something if both tools are run against the same prospects. The numbers above are context, not a verdict.
Emails are where accuracy claims get slippery, so process tells you more than percentages. Kaspr says its email data goes through a multi-step verification process and is re-validated every two months. Its plans split emails into B2B email credits, unlimited on paid plans, and direct email credits, which are capped at 60 a year on Starter and 2,400 a year on Business.
ReachStream Prospect includes a built-in email verifier, described as using credits only on verified data, and lists its emails as ESP-verified. Email views are capped at 200 a month on the free plan and unlimited on paid plans.
On Kaspr vs ReachStream accuracy, both describe verification and neither publishes an independent benchmark. For a wider look at how email finders stack up, see ReachStream’s accuracy comparison against Apollo and Hunter.
Kaspr’s core experience is its Chrome extension. A widget appears on a LinkedIn profile, shows a small preview, and spends a credit when you reveal contact details. It works on profiles, groups and events, with Sales Navigator support from Starter upward and Recruiter Lite on Business. If your process starts on LinkedIn, the Kaspr Chrome extension is the main event.
The ReachStream Prospect Chrome extension is available on every plan, including Free, and pulls verified contact details while you browse LinkedIn. The bigger difference is what sits behind it. ReachStream is also a searchable database, so you can build a list from filters without opening LinkedIn at all. Contact and company views are unlimited on every plan, and export credits are what you spend when you download or sync.
For a LinkedIn email finder comparison, that gives you two working styles: reveal as you browse, or build first and browse later.
Kaspr enriches in three ways: from LinkedIn, by uploading a CSV of LinkedIn URLs, and through an API available on request. Bulk runs are capped by plan, at 500 leads per launch on Starter and 1,000 on Business. Its integrations include HubSpot, Salesforce, Pipedrive, Lemlist, Brevo, Zoho, Aircall, Ringover and Zapier.
ReachStream Prospect data enrichment is included across plans, and ReachAPI, available on every plan including Free, covers pushing data into other systems. It connects natively with Salesforce and HubSpot, and any other system can be connected through ReachAPI. The two lists are not the same length, so check that your CRM or sequencer is on the one you are considering. For more on this, see our guide to CRM-compatible B2B data platforms.
Kaspr pricing is per user. Free costs nothing, Starter is $49 per user per month billed annually ($65 billed monthly), and Business is $79 annually ($99 monthly). Enterprise is custom, with unlimited credits. Kaspr’s paid plans list credit rollover, and add-on credits can be bought at any time.
ReachStream pricing plan is credit-based. Starter is $29 per month billed annually ($39 monthly) for 60,000 export credits a year. Pro is $49 ($59 monthly) for 120,000, and Business is $79 ($99 monthly) for 240,000, with up to three seats and a dedicated account manager. Enterprise is custom. Unused credits do not roll over.
In a ReachStream vs Kaspr price check, the credit systems measure different things, so a lower sticker price does not automatically mean a cheaper workflow.

Here is a simple sequence to help you choose the right B2B prospecting tool for your team.
Kaspr’s free plan includes 15 B2B email credits, 5 phone credits and 5 direct email credits a month, plus the LinkedIn extension and CSV enrichment at small limits.
ReachStream Prospect’s Free plan includes 100 export credits and 200 email views a month, the Chrome extension, data enrichment, and a small yearly allowance of AI Conversational Search and Similar Companies searches.
Both are enough for a proper sample. Neither is enough to run a full outbound motion. If you are shortlisting Kaspr alternatives with free plan options, look at B2B data providers with free trials, and treat free tiers as trial tools. They show you data quality, not what a busy quarter of outreach will cost.
ReachStream Prospect is a B2B data platform with 500M+ contacts, 50M+ companies and 100M+ direct dials across 150+ countries, and it is designed around building lists from filters. Contact and company data is searchable by job title, seniority, industry, revenue, location and technology, and the built-in email verifier is designed to check addresses before you export them.
Two features are worth a look if you prospect a lot. AI Conversational Search is designed to let you describe who you are looking for in plain language instead of stacking filters, and Similar Companies can make it faster to grow a target list from accounts that already fit your ideal customer profile.
It tends to suit teams that build lists at volume, enrich CRM records, or want a LinkedIn extension and a database in one place. If your process is almost entirely one profile at a time on LinkedIn, or you need an integration outside Salesforce and HubSpot, Kaspr’s setup may fit better.
Choosing between ReachStream Prospect vs Kaspr is not about a scoreboard. Kaspr can be a good fit when the work happens on LinkedIn profiles, particularly for European prospects and for teams that want phone numbers revealed one prospect at a time. ReachStream Prospect is a natural fit when you want to build lists from filters, enrich records in bulk, or keep a LinkedIn extension next to a searchable database.
If you are building a shortlist of the best B2B contact data tools 2026 has to offer, or working through Kaspr alternatives 2026 lists and other Kaspr competitors, run the same 50 to 100 prospects through each candidate, count the bounces and the connects, and price the credits you would really use. Then decide.
