Vibe Prospecting Is Shutting Down: What to Do Before December 2, and the Alternatives

Vibe Prospecting is shutting down. Explorium is ceasing operations, and it told Vibe Prospecting users by email on November 3, 2026 that the product is discontinued. It stays fully available until Wednesday, December 2, 2026: export your lists and use your credits by then. Credits still unused on that day are refunded within 30 days, and all data is deleted no later than December 31.

If you used it to find prospects for your outreach, the two closest alternatives are Apollo, to find the people at a company by job title, and Hunter, to find and verify the addresses at a company’s domain. Below are the dates, a checklist for the next four weeks, how the two compare, and how Personyze uses either one to find the person and write the personalized email.

When does Vibe Prospecting shut down?

Vibe Prospecting was Explorium’s prospecting tool inside the chat: you described the companies or people you wanted in plain English, and it searched, enriched and exported them, in its own app, as a connector (MCP) in your AI assistant, or through its API. This is what Explorium’s email says happens to it:

Explorium published the same terms for AgentSource, the API that Vibe Prospecting was also available through. If your systems call it, the same December 2 date applies to them.

What to do before December 2

Four weeks is enough, if you start with what cannot be recovered afterwards: your data.

• Export every list you still need. Your exported datasets are in the Hub, each with its status; Download is offered once a dataset is ready. Keep the lists you are still working, and the ones you already wrote to, so nobody is contacted twice.
• Export the enrichment too. Files you uploaded to the Hub and enriched there are data you paid for. Download the enriched version, not only the file you started from.
• Keep a record of your exclusion lists. The companies and people you chose to leave out should stay left out in whatever you use next.
• Use your credits, or let them refund. Credits still unused on December 2 come back within 30 days to the original payment method. Automated billing stopped on November 3.
• Write down what depended on it. Lists that fed your email sequences, the connector or plugin in your AI assistant, enrichment written into your CRM, scripts that call the API. Each needs a replacement by December 2.
• Claim a free month of Personyze. Vibe Prospecting customers get one month of Personyze free when they show a current or recent Vibe Prospecting invoice; claim it through our support team.
• Ask Explorium what this list does not answer: support@explorium.ai, from the email address of your Vibe Prospecting account.

Vibe Prospecting alternatives: Apollo and Hunter

No tool is a copy of a chat-first prospecting app. For the two jobs most outreach depends on, finding the right person at a company and getting an address that will not bounce, Apollo and Hunter each do one of them well.

Apollo: the right person, by job title

Apollo describes itself as one connected go-to-market platform: data, intelligence and execution. The part that replaces prospecting is people search: give it a company and the job titles you sell to, and it finds the people in those roles and reveals their work email, enriched with what Apollo knows about them.

In Personyze, you connect your own Apollo account with Connect with Apollo: you sign in to Apollo and click Authorize, with no key to create or paste. Personyze may only search people and reveal their work emails, and writes nothing to your Apollo account. Before connecting, it checks that your Apollo plan lets it search people. The Apollo guide has every detail.

Hunter: the address, found and checked

Hunter starts from a company’s web address. It finds the people with their own addresses at that domain, never a shared one such as info@, and says whether each address is valid. If you already know which companies you want, and need the person and an address that will be delivered, it is the shorter path.

In Personyze, Hunter connects with your Hunter API key: paste it into the Hunter card and click Connect, and Personyze checks it with Hunter before saving it. When the people at a company asked Hunter not to process their data, Hunter gives nobody there, and nobody there is written to. See the Hunter guide.

Apollo vs Hunter: which to pick

Side by side	Vibe ProspectingUntil December 2	ApolloAsked first	HunterThe fallback, or on its own
You start from	A sentence in a chat: who you are looking for	A company, and the job titles you sell to	A company’s web address
You get	Companies and the people at them, with enrichment such as firmographics, technographics, funding and contact details	The people in those roles, at the ranks that decide, and their work email	The people with their own addresses at that domain, never a shared one such as info@
The email check	—	Personyze writes only to an address Apollo calls verified, at the company’s own domain	Personyze writes only to an address Hunter calls valid; any other goes to your rep
What it uses	Vibe Prospecting credits; unused ones are refunded after December 2	One Apollo credit per person revealed; the search itself is free	One Hunter search per company looked up
In Personyze	—	Connect with Apollo: sign in to Apollo and click Authorize, with no key to paste	Paste your Hunter API key; Personyze checks it with Hunter before saving it

• Pick Apollo if you search by role: the Head of Operations, the VP Ecommerce, whoever decides at a company you have not spoken to.
• Pick Hunter if you start from a list of company domains and need a verified address at each.
• Or connect both. Personyze asks Apollo first and Hunter only when Apollo has nobody at a company, so a company Apollo answers for uses none of your Hunter searches. Either one also works alone.

Both are your own accounts, with your own credits. What either answers about a company is kept for 30 days, so the same company is never paid for twice in that time.

Finding the person and writing the email, in one place

A prospecting tool gives you a list. What you do with it, the page each person sees and the email each person gets, happened somewhere else. In Personyze the two meet, and AI does the writing.

Company follow-up: the right person at a company that reads your site

The prospects most worth writing to are often the companies already reading your pricing page. When your company-identification tool, such as Albacross, Leadfeeder, Snitcher, ZoomInfo or Demandbase, names one, Company follow-up checks that it fits: its industry, size and country, and the pages it read. It finds the right person there with your Apollo account, or Hunter when Apollo has nobody, writes a page of three ideas for their own site, and has AI write one short email from that page. Your rep approves each email before it goes.

Written from her page, what you sell and Jordan’s own words. It goes from Jordan, Tuesday to Thursday, 9–11 a.m. her time.

Demo mode firstThe person is found, the page made, the email written and your rep told, but nothing is emailed until you start sending.

• Your rep approves each email, under Identified companies or on a phone, straight from the alert: Approve & send, Edit, Skip, or Copy to send it from their own mailbox. What your rep approves is what is sent, from your rep, in the recipient’s working hours.
• Your rep’s alert comes on Slack and by email, with the company, why it fits, the person, and a LinkedIn note of up to 300 characters to copy. LinkedIn is never automated.
• Demo mode first. Everything runs except the sending, until you start it.
• Limits: a company is noted once, however many of its people visit, and followed up again only after 30 days, at most 20 a day. Your own domains, your customers and your competitors are never followed up.
• Replies go to your rep, and into the panel’s Inbox. For each company you see what happened: sent, opened, opened their page, replied or bounced.

Our Company follow-up post walks through a whole example, and what each company sees on your site while it reads is on B2B personalization.

AI emails for the people you already exported

The lists you take out of Vibe Prospecting do not have to sit in a spreadsheet. Under Settings › Imported user data, an uploaded file puts them on a list, keyed on email, with columns such as first name, last name and industry filling their profile.

Load status, without the round of calls

Hi Sam,

At a distribution company, every late load starts the same round of calls to dispatch. Lanewise gives each load one live tracking link your customers can open themselves.

Would a 20-minute walkthrough be useful? Jordan

Email 2 in 4 days · stops if Sam repliesApprove

Then an Automatic AI emails campaign writes to each person as they join that list: their own email, from your instructions, a few emails you wrote yourself as examples, and what is known about them and their company. It is told never to invent a price, a date or a promise. Up to five follow-ups can come after it, and the sequence ends when the person replies.

• Publish first, then upload. Only people who join a list after the campaign is published are written to.
• Big imports wait for you. When more than 100 people join at once, nobody is written to until you press Email them or Skip them.
• Review first is the default. Each draft waits on Activity for your OK, until you choose Send by itself.
• Caps you set: 5 to 60 emails an hour and 20 to 300 a day for the campaign.

For the conversations that follow a demo or a call, Personal emails writes one email to one person from your note, and you send it. When their address is at a company’s own domain, the AI also reads what Personyze found on that company’s site. Both are part of email personalization; as with any outreach, write only to people you may email.

The short version

Export everything by Wednesday, December 2, and let the unused credits refund. Then use Apollo or Hunter for finding the people, and Personyze for what they see on your site and what they are emailed: Company follow-up for the companies reading your site, and AI emails for the lists you already have.
