Coresignal
Coresignal sells public web data on companies, employees and job postings, collected from professional networks, job boards and review sites and delivered as datasets, APIs and searchable lists. Its employee data covers more than 900 million records with over 300 fields, its company data more than 70 million and its jobs data more than 480 million, with social posts from companies and employees added in 2025. Revenue teams are one market among several, alongside AI developers, investors, HR technology companies and researchers.
For sales use, AI Data Search turns a written description of a target market into a list of up to 10,000 companies or people that can be refined in chat, enriched and downloaded, and the same prompt returns the same list each time. The Agentic Search API translates plain language into structured queries against Coresignal's own indexes, with a fast mode and a slower reasoning mode, and Contact Enrichment adds professional emails, each with a verification status and confidence score, for people outside the EEA and UK. Data reaches customers through an MCP server for AI assistants, n8n, Zapier, Clay, Snowflake, Databricks and cloud storage, though there is no direct CRM connector.
Self serve plans run from $49 a month for 2,500 credits to $5,000 a month for 10 million, with a full employee or company record costing 20 credits and an email 10, and full datasets start at $1,000 on an annual contract. Contracts are signed by Deeptrace Inc. in Delaware, the company dates itself to 2016, and it is a founding member of the Ethical Web Data Collection Initiative.

The Agentic Search API turns plain language into Elasticsearch queries grounded in Coresignal's own index schemas, with semantic matching of job titles, and AI Data Search uses an agent to build and refine lead lists in chat. A few fields, such as a profile score and projected salary, are model derived. Underneath sit scraped datasets and record APIs that are sold on their own and work without the AI layer.
Little runs on its own, and nothing writes into customer systems. Monitors check up to 10,000 profiles weekly and report changes by email or webhook, with five monitors per team that expire after 90 days, and credits cap what any query can spend. The reasoning search mode can stop to ask a clarifying question, and the MCP server pauses for confirmation before large pulls, while what happens when a search returns the wrong people is left to the user.
No model or AI provider is named, and the reasoning mode runs on a more powerful model than the fast one, with neither identified. AI Data Search shows how it generated each list and returns the same results for the same prompt, which lets buyers check its work.
Results appear only as anonymous testimonials, such as a lead generation client reporting 25 percent more net new pipeline in two months and 40 percent after six, and a venture firm saying data now shapes 65 percent of its investments, up from about 2 percent. No named case studies exist, client counts range from 500 to more than 1,000, and record totals from 4.5 to 5 billion.
Contracts make the customer solely responsible for data protection as an independent controller and forbid using the data for bulk mail. Emails are withheld for people in the EEA and UK, legitimate interest is the stated legal basis, and an online form handles opt outs, access, deletion and correction without a stated response time. No data broker registration is named for any US state, and the impact assessment behind the legitimate interest basis is not public.
Binary House LLC is the controller for profile data, with no address given, while contracts are signed by Deeptrace Inc., and profile data is kept for up to five years from the latest collection. Transfers to Deeptrace, Google and Meta in the US rely on unnamed contractual clauses, neither contract references a DPA, and no subprocessor list or breach notice timing is given. Emails may be derived from a person's name and company domain.
Named sources include Glassdoor, Indeed, Docker Hub, Owler, the Chrome Web Store and Craft, alongside a professional network that supplies most company, employee and jobs data and is never named. Collection is open scraping of public pages without logging in, with no third party collectors, and Coresignal rests its legality on the hiQ v. LinkedIn and Meta v. Bright Data rulings and on accreditation by the Ethical Web Data Collection Initiative. The contracts deliver the data as is and put compliance on the customer, and APIs are live while datasets refresh daily, weekly or monthly.
Most employee, company and jobs data is scraped without logging in from what Coresignal calls the world's largest professional network, and its opt out form asks for a LinkedIn profile link. LinkedIn's user agreement prohibits scraping, and the case for collecting anyway rests on court rulings about public data rather than any permission or partnership.
Whether customer queries or data train models is not addressed, and feedback on AI Data Search sends the query and its results to Coresignal. Profile data is kept for up to five years, and delivered data does not have to be deleted when a contract ends.
Nothing is sent to prospects, and customers carry the data into their own outreach. No notice to the people whose profiles are collected is described, and no position on Article 50 of the EU AI Act is taken.
An MCP server with OAuth sign in brings entity search and email enrichment into Claude Code, Codex and Cursor, and a native n8n node, Zapier, Clay, Databricks, Snowflake and delivery to S3, Azure or Google Cloud storage cover data pipelines. The API uses key authentication with rate limits from 5 to more than 100 requests a second by plan, the reasoning search allows ten calls an hour, and webhooks report record changes. Salesforce, HubSpot and other CRMs have no direct connector.
Google is named as a US infrastructure provider, but hosting regions and residency choices are not described. Datasets can be delivered to the customer's own S3, Azure or Google Cloud storage or by download link.
Security practice follows ISO 27001 requirements without formal certification, with encryption, breach response and restricted access as the named controls. No SOC 2 report, trust center or sign in controls such as single sign on are listed.
Self serve plans are priced with their credits, from Mini at $49 a month for 2,500 credits through Starter at $199, Pro at $499, Growth at $1,000, Premium at $1,500 and Scale at $3,000 to Elite at $5,000 for 10 million. Annual billing runs 10 percent lower, from $2,149 a year for Starter to $54,000 for Elite, unused credits roll over for three months, and a seven day trial gives 2,000 credits.
A full employee or company record costs 20 credits, a core record 10, an email 10, a job or post one, and agentic searches 20 or 100. AI Data Search prompts are free, previews cost 20 credits, and full datasets start at $1,000 on an annual contract.
Self serve plans cancel at any time and run to the end of the paid cycle, with credits not refundable. Under the master agreement, terms follow the order form and may renew automatically unless stopped 30 days ahead, early exit requires an uncured breach, and delivered data can be kept after the contract ends, with sufficiently altered derivative works licensable onward. Data exports as CSV, JSONL or Parquet, disputes go to arbitration under Delaware law, and liability is capped at twelve months of fees.
Each email carries a status of verified or catch all and a confidence score, but the checks behind them are not described, and some addresses are derived from a person's name and company domain. No accuracy or bounce guarantee is offered, and the contract supplies data as is.
AI developers, sales and marketing teams, sales and market intelligence platforms, investors, HR technology companies and researchers are all buyers, so revenue teams are one market of several. Customer evidence is anonymous apart from universities in a pro bono research program, and customer sizes and geographies are not stated.
