The List Is Wrong. Say So, in a Sentence.

What People Ask before Trying It

Fifteen questions people ask about AI B2B lead search in ReachStream Prospect. A 20-minute demo answers the rest faster than this page can.

What is Conversational Search in ReachStream Prospect?

Conversational Search is AI B2B lead search inside ReachStream Prospect. Describe the buyer you want in plain English and it builds the filtered B2B contact search: industry, job function, seniority, location, headcount, and technology. Every filter stays visible and editable.

It maps each phrase in your sentence to an attribute ReachStream Prospect already holds, applies those as real filters, and returns verified contacts. You find decision-makers at companies that match your description without writing a query.

Yes. Conversational Search sets ReachStream Prospect’s own B2B prospecting filters, and all of them stay on screen and editable. Start with a sentence and finish by hand, or the other way around.

Job function, job title, seniority, industry, location, headcount, and the technology a company runs. A prompt such as “Marketing heads at SaaS companies in Austin with 50 to 200 employees” uses five of those at once.

Yes. Every filter the B2B prospect list builder sets is a normal ReachStream Prospect filter. Change it, remove it, or add one it missed, without rewriting your sentence.

Send a follow-up instead of starting again. “Only the ones with a direct dial” narrows it, “widen it to Georgia and Alabama” opens it back up. The B2B lead list builder never makes you start over.

Every plan, including Free. Plans differ in how many Conversational Searches you get, not in whether the feature is available. Free includes two per month.

No. Searching and refining do not spend export credits. Credits are spent only when you export verified contacts: one per contact with an email, ten per phone number, one per company export.

Yes. Email verification runs inside ReachStream Prospect before you download, and deliverability is guaranteed at 90% on the emails you export.

No. ReachStream Prospect does not provide intent data. Conversational Search works on the firmographic, contact, and technographic attributes in the database.

A general AI tool searches the open web and hands you text. AI B2B lead search in ReachStream Prospect searches a verified B2B contact database and hands you an editable filtered list you can export. That is the difference between a chat tool and AI sales prospecting.

Yes. One sentence carries who the person is and what the company looks like: “Revenue operations leads at companies already running HubSpot” sets a function, a seniority, and a technology filter together.

Name the role and the company in the same breath, and be specific about scale and place. “Operations managers at third-party logistics companies in Texas with 200 to 1,000 employees” works because every phrase is an attribute. “Good leads for us” does not.

Run one persona per search. A prompt asking for two roles at two kinds of company produces a list you then have to untangle. Run the second as its own search.

Look at the filter panel first: it shows exactly what your sentence resolved to. Usually one phrase mapped wider or narrower than you meant. Edit that filter, or send a follow-up naming the change.
