Raw Data API or Sales Platform?
Comparing Coresignal and SalesIntel is like comparing a lumber yard to a furniture store. One sells raw materials to people who build things; the other sells finished products to people who sit in them. They serve fundamentally different buyers - and if you're weighing them against each other, you're probably unsure which type of buyer you are.
Here's the short answer: if you don't have a data engineer, you don't want Coresignal. If you can't budget $17,600/year before add-ons, you don't want SalesIntel. Most teams need neither.
30-Second Verdict
Coresignal is for data engineers building enrichment pipelines, data products, or AI models. It's API-first, and while it offers a self-serve platform to search and download custom datasets, it doesn't come with native CRM sync or sales workflow tooling. Raw datasets via API - you build the system around it.
SalesIntel is for sales teams that want a searchable contact database, human-verified records, Bombora intent data, and native CRM integrations. The median contract runs $17,599/year across 20 Vendr-benchmarked deals - before add-ons.
Skip both if you want verified contact data without an engineering team or a five-figure annual contract.
Feature Comparison
| Coresignal | SalesIntel | |
|---|---|---|
| Database | 839M employee records, 75M company records | 200M+ contacts, 30M accounts |
| Data type | Raw datasets + API | Searchable contacts |
| Email accuracy | N/A (raw data) | 60-95% (varies by verification tier) |
| Verified mobiles | Not a "verified mobile" product | Yes (limited) |
| Data refresh | Monthly cycle (often 3-4 months old) | 90-day reverification (Human Verified) |
| Verification | None (raw) | Human + email + machine |
| Intent data | None | Bombora (limited portion of Company Surge, Enterprise tier) |
| CRM integrations | No native CRM sync | Salesforce, HubSpot, etc. |
| Compliance | EWDCI certified | GDPR/CCPA-aligned |
| Pricing | $49-$1,500+/mo | ~$17.6K/yr median |
| Best for | Data engineers | Sales teams |
Coresignal's raw record count looks massive, but those are public web records - not sales-ready contacts. SalesIntel's 200M+ contacts are more actionable out of the box, though accuracy swings wildly depending on which verification tier you're pulling from.
Pricing Breakdown
Coresignal offers a 14-day free trial with 200 Collect and 400 Search credits. The $49/month Starter plan gives you a tiny monthly credit allotment - that's not really a plan, it's a free trial that charges you. Meaningful usage starts at $500+/month. Pro begins at $800/month (at least 10,000 Collect + 20,000 Search credits), Premium at $1,500/month (at least 50,000 Collect + 150,000 Search credits), and larger enterprise usage often lands in the $5,000-$10,000+/month range. Yearly billing saves 20%. Flat-file dataset pricing is contract-based and varies by scope, with packages starting from $1,000.
SalesIntel's median contract is $17,599/year, with a range of $8,670-$41,380 across Vendr-benchmarked deals. Some contracts still follow legacy credit-based tiers ($99-$225/month for individuals, $18K-$48K/year for teams). Add Bombora intent data ($5,000-$10,000/year) and VisitorIntel ($1,000-$3,000/year), and a 5-user team should budget $23,000-$31,000/year. Multi-year deals can knock 25% off, and end-of-quarter timing gives you negotiating room.
Look - SalesIntel markets "unlimited credits," but Research on Demand, where actual humans verify contacts, is capped at 10 lookups per user per month. There's also a 500-contact export limit per pull. That's not unlimited.
SalesIntel's machine-verified tier bounces above 30%. Coresignal doesn't verify at all. Prospeo delivers 98% email accuracy through 5-step verification with spam-trap and honeypot removal - refreshed every 7 days, not every 90.
Stop filtering out bad data. Start with data that's already clean.
Data Quality Deep Dive
SalesIntel runs a three-tier verification model. Human Verified contacts hit ~95% accuracy and get reverified every 90 days. Email Verified sits at ~90%, reverified every six months. Machine Verified drops to ~60%. We've seen the machine-verified tier produce bounce rates above 30% in outbound campaigns, which is enough to torch your sender reputation in a week.
The gap between tiers matters more than the headline number. When SalesIntel says "up to 95% accuracy," they mean the best tier. The contacts you actually pull can include multiple tiers depending on how you filter - and if you're not careful with those filters, you'll end up with a blended accuracy rate that's nowhere near 95%.
On G2, SalesIntel holds a 4.3/5 across 538 reviews. "Ease of Use" leads the praise with 90 mentions, but "Inaccurate Data" and "Outdated Data" tie as the top complaints at 40 mentions each. The pattern is consistent: the good data is genuinely good, but you're constantly filtering out the bad.
Coresignal refreshes on a monthly cycle, but data can be 3-4 months old between cycles. For raw datasets feeding AI models or market research, that's acceptable. For sales outreach, it isn't. Across the broader B2B data market, accuracy ranges from 63% to 91%-accuracy-coverage-real-results), which is exactly why single-source reliance is risky regardless of which provider you choose.
Who Should Choose Which
Choose Coresignal if you have a data engineer who can work with Elasticsearch Query DSL, you're building a data product or AI training dataset, and you need bulk employee, company, or job posting data as raw files. If you don't have a data engineer on staff, don't even consider it. Coresignal is unusable for 90% of sales teams.
Choose SalesIntel if you run a sales team that needs contacts, intent signals, and CRM integration in one platform. You want human-verified data with a searchable UI, you can budget $17K+/year before add-ons, and you want intent signals pushed directly into your CRM. Note that Bombora intent data requires the Enterprise tier - and it's a limited portion of Company Surge, not the full dataset.
Let's be honest: most teams comparing these two tools are overthinking it. If your average deal size is under $15K, you don't need Coresignal's raw data infrastructure or SalesIntel's enterprise pricing. You need accurate emails, direct dials, and a way to get contacts into your CRM without calling a sales rep.
If Neither Fits
Prospeo fills the gap between raw API and enterprise sales platform. 300M+ profiles, 98% email accuracy, 125M+ verified mobiles, and a 7-day data refresh cycle - about 13x faster than SalesIntel's 90-day reverification. The Chrome extension has 40,000+ users, and native integrations push contacts straight into Salesforce, HubSpot, Lemlist, Instantly, and more. Pricing starts free with 75 verified emails and 100 Chrome extension credits per month, with paid plans running about $0.01 per lead. No contracts, no sales calls.
You don't need a data engineer or a $17K annual contract to reach decision-makers. Prospeo gives you 300M+ profiles, 125M+ verified mobiles, and native CRM integrations - starting at $0.01 per lead with no sales call required.
Enterprise-grade data without the enterprise pricing or friction.
FAQ
Does Coresignal have CRM integrations?
No. Coresignal is API-first and built for teams that can pipe data into their own systems via Elasticsearch Query DSL. It offers a self-serve platform to search and download custom datasets, but there's no native Salesforce or HubSpot sync - you'll need engineering resources to connect it to your stack.
How does SalesIntel's data accuracy hold up?
Human Verified contacts hit ~95% accuracy, but Machine Verified drops to ~60% with bounce rates above 30%. Always filter for the highest verification tier. If you're pulling mixed-tier results, expect inconsistent deliverability across your outbound campaigns.
Which is better for small teams?
Neither. Coresignal requires engineering resources most small teams don't have, and SalesIntel's median contract is $17,599/year. Self-serve platforms like Prospeo offer 75 free verified emails per month, transparent credit-based pricing at ~$0.01/lead, and no annual commitment - a better fit for teams under 10 reps.
