Prospectrum finds plumbers,
scores every one against criteria you set, writes the first email, and hands you the reply. It runs personalized outreach at a scale and speed you couldn't manage by hand, reaching more businesses in less time and turning more of them into customers. You just say yes.
Works for any industry, in any city. You decide what a good lead looks like, and we do the finding, the writing, and the following up.
What we do
Four things used to eat a seller's week: finding businesses worth a shot, writing something worth opening, chasing replies, and hoping the person on the other end didn't mind the interruption. Prospectrum runs all four, automatically, and in a way the business on the other end doesn't mind either.

To start prospecting
Set your city, category, and criteria once. Everything below happens on its own from there, the same day and every day after.
Stage 01
Give it a city and a category, any trade. It scans for the tells: no SEO, an unclaimed Google listing, a homepage that still says "Under Construction." You never touch a spreadsheet.
Signals it looks for
Stage 02
Every business gets graded against criteria you set, not a generic checklist. Weak fits get filtered out before they ever reach your queue.
A live reading
Three businesses, one afternoon, graded against your criteria, not ours.
Stage 03
It writes the first email itself, grounded in something real about that business, in their own language. Not a {{first_name}} mail-merge.
What lands in their inbox
Subject: quick one about your Google listing
"Noticed De Groene Winkel's listing hasn't been touched since 2019, even with five-star reviews stacking up. Happy to help if useful, no pressure either way."
One relevant line, not a blast. That's most of why it gets replies.
Stage 04
When someone replies, it reads the tone. Interested goes straight to your calendar link. Not interested gets a polite close. You only see the ones worth your time.
What happens when they say yes
Them: "Yeah, go ahead."
Prospectrum: books them straight onto your calendar. No back-and-forth, no form to fill in.
The easier it is to say yes, the more of them do.
Whatever you sell and wherever you sell it, you set the criteria for what's worth pursuing. Free to start, and you'll have your first leads before lunch.

Who it's for
Prospectrum ships with 57+ business categories already built in, everything from plumbers to law firms to yoga studios. What counts as a good lead is never our call to make. You describe your ideal customer, and we go find, score, and reach out to them ourselves, whatever the trade.
The reading
Every business gets logged the same way: site, SEO, listings, all of it, automatically, so nobody's doing this by hand across a hundred tabs. Pick the trade you're prospecting in below and see the same engine adapt to it, in real leads and real criteria.
What you'd type
"Small, family-run shops and restaurants with no working site or an abandoned Google listing. Skip anything that smells like a franchise."

Questions
Prospectrum searches any city and category you choose, then checks each business for weak digital signal, things like an unclaimed Google listing, no online booking, or a site that hasn't changed in years, and scores them against the criteria you set.
