Explorium announced on November 3, 2026, that it’s shutting down. AgentSource and Vibe Prospecting both end on December 2, 2026, which is the day data exports stop. Unused credits are refunded within 30 days, and account data is deleted by December 31. Anything that depends on either product needs a tested replacement before December 2.

What did Explorium announce?
Explorium announced on November 3, 2026, that it would cease operations after almost nine years. It sent similar announcements in a notice to AgentSource customers and its update for Vibe Prospecting customers.
| Date | What happens |
|---|---|
| November 3, 2026 | Explorium announces the shutdown. Automated billing stops. |
| December 2, 2026 | AgentSource and Vibe Prospecting are discontinued. Data exports are available until this date only. |
| Within 30 days of December 2 | Credits that are still unused are refunded to the original payment method. |
| By December 31, 2026 | Explorium deletes all data and account information, keeping limited billing records where the law requires it. |
Vibe Prospecting is the in-chat prospecting app that grew out of Explorium's MCP server, and the founders' post says it has more than 350,000 registered users. Explorium may publish more details, so check its pages for the current terms.
What should Explorium users do before December 2?
Export your data first, because you can’t get it after December 2. Then test a replacement before you switch.
- Export what you want to keep. Download the lists, enriched records and saved searches you rely on. Explorium's notices say exports are available until December 2 only.
- List every call your workflows make. For each AgentSource endpoint, Vibe Prospecting prompt, MCP tool or integration step, write down what you send and the fields you read back. That list is the specification for your replacement.
- Build a test set from your own data. Take 500 to 1,000 records from your CRM or lead lists, and include the hard ones: small companies, people outside the US, rows with no domain.
- Run every candidate on the same set. Measure how many records come back, how often the fields you read are filled, and how old each record is.
- Check the integration details. Authentication, rate limits, response times and error codes decide how much of your pipeline has to change.
- Run both side by side before you cut over. Both products stay available until December 2, so you can compare outputs for a few days while they are still running.
- Keep your account email and invoices. The refund goes to the original payment method, and Explorium asks for the email linked to your account when you contact support.
How do you choose a replacement?
Match the replacement to the way you use the data. You can use these same six questions for any provider:
| Question | What to look for |
|---|---|
| Do you call it per record or load it in bulk? | A per-call API fits enrichment inside a form, a CRM or an agent. A dataset license fits loading records into your own warehouse. They are different products. |
| How complete are the fields you use? | Ask each provider for the fill rate on your three most important fields, then check it on your test set. |
| How old is each record? | A timestamp on every record tells you more than "updated monthly". |
| How is a match scored? | Look for a confidence value on lookups, so you can set your own threshold. |
| What are the limits? | Rate limits, response times, and whether you can call from a browser. |
| What notice do you get before things change? | Ask for the commitment on breaking changes and the terms for exporting your data. |
Our guide to evaluating a data enrichment provider covers five structural dimensions in more depth, and how to test and evaluate a data enrichment dataset walks through the test.
Where does Enrich Layer fit?
Enrich Layer is a B2B data enrichment API for people and company data. You send one request for a person or a company and get the record back as JSON.
Our API covers person profiles, company profiles, person and company search, employee lists and counts, work email lookup, reverse email and phone lookups, and job postings.
If you used Vibe Prospecting from inside an AI chat, you can connect Enrich Layer's hosted MCP server to Claude, Cursor, VS Code or ChatGPT. The MCP setup page has the steps for each.
Person Profile and Company Profile responses include meta.last_updated, so you can see how old a record is, and meta.thin_profile, which flags a sparse record. Set use_cache=if-recent to accept a cached profile only when it is under 29 days old, and an older one triggers a live fetch. Enrich Layer commits to no breaking API changes without 30 days' notice.
Enrich Layer returns one record per call. If your workflow depends on loading a full dataset into your own warehouse, check the list of calls with no direct equivalent in the migration guide before you commit.
How do Explorium calls map to Enrich Layer?
Single-record calls have a direct equivalent, and a few features do not.
| Explorium | Enrich Layer | How close |
|---|---|---|
| Match businesses | Company Lookup | Same job, one company per call. |
| Match prospects | Person Lookup, Reverse Email Lookup and Reverse Contact Number Lookup | Same job, with one endpoint for each identifier. |
| Fetch businesses and prospects | Company Search and Person Search | Part of the job. There are no filters for revenue, industry codes, seniority or department. |
| Firmographics | Company Profile | Part of the job. There is no revenue range and there are no industry codes. |
| Person profiles | Person Profile | Part of the job. There is no age group, seniority or department. |
| Work email | Work Email Lookup | Part of the job. The address is sent to a callback URL. |
| Technographics, buyer intent, event feeds and statistics endpoints | None | No equivalent. |
Our Explorium to Enrich Layer migration guide maps each Explorium operation and the main fields, and includes a script that re-keys a list of companies.
How to try Enrich Layer on your own records
Create an account. New accounts include free trial credits. Run your test set against the calls in the migration guide, and compare the results with your Explorium export. Check the rate limits first, because trial accounts have a lower limit than paid ones.
Explorium customers can get their unused credits matched, plus up to 3x on their first top-up.
