Contact data and enrichment, indexed from public professional profiles
Primary sources checkedSignalHire
SignalHire finds verified work and personal email addresses and phone numbers for people you have already identified, through a browser extension, a searchable database of 850M+ profiles, bulk CSV enrichment and an API, with ATS and CRM sync included on every paid plan. It indexes public professional profiles and processes them under legitimate interests, and publishes an opt-out route.
The short answer
- Best for
- A sourcer or agency desk that already knows who it wants and loses the day to finding a working email or a mobile number, and wants unlimited seats rather than paying per recruiter
- Not ideal for
- Teams whose real problem is candidate discovery rather than contact details, and organisations that cannot accept a legitimate-interests basis for processing candidate data
- Price
- Free tier; paid from around $69/month, or around $57/month billed annually
- Closest alternative
- ContactOutThe comparable recruiter-focused contact-data tool, when you want a product built around recruitment sourcing rather than one that serves sales and recruitment from the same database.

Why these assessments
- Recruitment fitFair
- Genuinely useful in recruitment and not built only for it: the same database and the same enrichment serve sales prospecting, and the ATS and CRM integrations are listed side by side. The recruiter-specific parts are real — Zoho Recruit, Recruitee, Ashby and Workable are named connectors — but the product is a contact-data layer rather than a recruitment product.
- Ease of useUnknown
- SourcrLab has not used it. On a contact-data tool ease is really hit rate on your own roles — how often the extension returns a number that actually rings — and that is invisible until real searches go through it. The free tier is where a buyer settles it.
- ImplementationStrong
- A browser extension and a free tier with no card mean the first real test takes minutes, and every paid plan includes unlimited users, so rolling it out to a team is not a second purchasing decision.
- Price transparencyFair
- Plans and rates are published for monthly and annual billing, and the free tier is explicit. The pricing page is harder to read than it should be: several plans render at the same headline price with different credit counts, and the annual view mixes a monthly rate with what appears to be an annual credit total. The credit allowances are therefore carried as unknown rather than reconstructed.
- Value for moneyUnknown
- Not assessed. The prices are published and the unlimited-users model is genuinely favourable, but value on contact data is entirely hit rate against your own market, and SourcrLab has not measured it. The vendor's own accuracy figures are its claims.
- ScalabilityStrong
- Unlimited users on every paid plan is the unusual part: cost scales with credits consumed rather than with headcount, so adding a recruiter costs nothing and a quiet month costs less than a busy one. Unlimited exports and an API make the same data usable in bulk.

The SourcrLab bottom line
A contact-data layer with an unusually buyer-friendly commercial model and a data-protection position that deserves reading. The product is four routes to the same thing: a Chrome and Firefox extension that reveals contacts on social media and websites and carries ten free credits a month, a database of 850M+ profiles and 30M+ companies the vendor says is updated every seven to ten days, bulk enrichment of up to a thousand people per CSV run, and Person and Search APIs with key-based authentication. Email sequences with Outlook and Office 365 tracking sit on top. Every paid plan includes unlimited users, unlimited exports, team management, the browser extension, ATS and CRM sync across 25-plus platforms including Salesforce, Zoho Recruit, Pipedrive, Recruitee, Ashby and Workable, and API access — so seats are never the cost, credits are. The accuracy claims are the vendor's own: 95%+ email accuracy with live verification, emails for up to 90% and phones for up to 80% of profiles. The privacy position is stated plainly and is the part to read twice.
Best fit
A desk whose sourcing already works. You can find the right twenty people; what costs the afternoon is turning them into twenty ways of actually reaching someone. SignalHire is built for exactly that gap — a browser extension that reveals contacts on the profile you are already looking at, a database to search when you are not, bulk enrichment for a list you already have, and an API when the list comes from your own system. Unlimited users on every paid plan means the whole team gets it for the price of the credits.
Think twice if
Understand what you are buying into on data protection, because it is the substance of this purchase rather than a footnote. SignalHire indexes public professional profiles the way a search engine does, and its lawful basis for processing those people's data is legitimate interests, not their consent. That is a defensible and common position for this category, and it is not the same as the candidate having agreed to anything. The vendor complies with GDPR as a baseline, applies CCPA and Virginia's law for those residents, publishes an opt-out route, and states a retention period of typically up to seven years. If your organisation runs a data-protection impact assessment on candidate data, this is the tool that will need one.
SourcrLab assessment
Everything on this page comes from the vendor's own pages, checked on the dates below. SourcrLab has not used this product in real recruitment work, so you will not find a first-hand opinion here.
Why choose SignalHire?
Seats are free; you pay for data
Unlimited users on every paid plan, including the cheapest, is rare in this category and changes who can use it. A five-person desk pays the same as one recruiter for the same credits, so the tool ends up on everyone's browser instead of being rationed to whoever has the licence.
Four routes into the same data
The extension for profiles you are looking at, the database for people you have not found yet, CSV enrichment for a list you already hold, and an API for a list your own system produces. Most tools in this category do one or two of those well; covering all four means the data fits however your sourcing actually works.
The data-protection position is written down and checkable
The privacy policy states where the data comes from, names legitimate interests as the lawful basis for professional profiles, commits to GDPR as a baseline, covers California and Virginia residents, gives a retention period of typically up to seven years, and publishes an opt-out link. Plenty of tools in this category leave a buyer guessing at all five.
A free tier that answers the only question that matters
Five credits a month, or ten with the extension installed, and no card. That is not enough to work with and it is exactly enough to find out whether the numbers it returns for your kind of role actually ring, which is the whole basis on which contact data should be bought.
Main trade-offs
Legitimate interests, not consent
The people in the database did not agree to be there. The vendor indexes publicly available professional information the way a search engine does and processes it under legitimate interests, which is a lawful basis rather than permission. That is standard for the category and it is still a position your organisation adopts when it buys. If candidate data goes through a DPIA where you work, budget for one.
The pricing page is hard to read reliably
Several plans render at the same headline price with different credit counts, and the annual view shows a monthly rate next to what looks like an annual credit total rather than a monthly allowance. The prices themselves are legible; how many credits each buys is not, and it is not reconstructed here. Confirm the monthly credit allowance for the exact plan you are signing.
A credit is not a working phone number
The vendor states 95%+ email accuracy with live verification, and coverage of up to 90% for emails and 80% for phones. Those are its own figures and they describe the database, not your market. Coverage on senior technical roles in a small European country is a different number from coverage on US sales profiles, and only the free tier tells you which one you are buying.
It finds contacts, it does not find candidates
The database is searchable, but the product's centre of gravity is turning a person you have identified into a way of reaching them. A team whose actual problem is not knowing who to approach is buying the wrong half of the workflow, and should look at sourcing platforms instead.
Pricing and buying reality
Free tier with no card; paid from around $69/month, or around $57/month billed annually
- Free: $0 a month for 5 credits, or 10 with the browser extension installed, with no credit card required
- Paid plans are split by what a credit reveals: Emails, Phones, or Emails and Phones, each with a capped-credit and an unlimited variant
- Monthly billing: capped-credit plans around $69 a month; unlimited variants around $79 for Emails and around $99 for Phones and for Emails and Phones
- Annual billing: capped-credit plans around $57 a month; unlimited variants around $63 for Emails and around $83 for the phone-carrying plans
- Every paid plan includes unlimited users, unlimited exports, CSV enrichment, team management, the browser extension, ATS and CRM integration and API access — seats are never the cost
- A Scale tier for larger volumes is quoted on request
What we do not know
- The monthly credit allowance on each paid plan. The page shows several plans at one headline price with different credit counts, and the annual view mixes a monthly rate with what appears to be an annual credit total, so no allowance is published here
- What counts as one credit on each plan type, and whether unused credits roll over
- Scale tier terms, and any minimum commitment on annual billing
- Data-residency options and whether a DPA is offered as standard

How it fits your stack
Works with
- 25-plus ATS and CRM platforms including Salesforce, Zoho Recruit, Pipedrive, Recruitee, Ashby, Workable, ActiveCampaign and ClickUp
- Chrome and Firefox, through the browser extension
- Outlook and Office 365, for email sequence sending and tracking
- Your own systems, through the Person and Search APIs
Likely replaces
- Guessing an email format and testing it by sending
- A separate bulk-enrichment service for a candidate list you already have
- A per-seat contact-data licence rationed to one recruiter
May overlap with
- Recruiter-focused contact tools such as ContactOut, and sales-first data providers such as Lusha and Apollo
- The enrichment layer inside a sourcing platform you may already run
Check before buying
- Hit rate on twenty people you already have the contact details for, using the free tier, before any plan is chosen
- The monthly credit allowance for the exact plan you would sign, since the pricing page does not make it legible
- Whether your organisation accepts legitimate interests as the basis for processing candidate data, and whether a DPIA is required
- That your specific ATS is one of the named integrations, not merely a category
SignalHire vs alternatives
Products a buyer would genuinely put next to this one, with the reason you would pick each instead.
Choose ContactOut when you want a contact-data tool built around recruitment sourcing specifically, rather than one serving sales and recruitment from the same database.
Choose Lusha when the buyer is commercial as well as recruiting and you want a provider whose compliance posture is built around B2B sales data.
Consider RocketReach for a comparable breadth of contact data with a different credit model, if the deciding factor is coverage on your specific market rather than the seat policy.
