A fresh sample for every experiment
9.5 million companies you can search by what they do, not only by industry code. Describe the segment in your hypothesis, and email only companies that have never heard from you.
- ✓ Previously contacted companies excluded
- ✓ No credit card required
Describe the segment exactly
A segment where everyone shares the same problem replies more often, and a higher reply rate reaches a verdict with fewer emails.
Company profiles
- ✓ Search by the company's own description of what it does
- ✓ Industry, size and keywords
- ✓ Geographic data — country, state, city
- ✓ General company contacts & socials
US software companies with 2–20 employees whose description says “our platform helps”.
The people you'd email
- ✓ Key professional details & job title
- ✓ Current & past employment history
- ✓ Work email & phone with verification status
- ✓ Professional social profiles
At each of those companies, the founder or CEO, with an email that passes verification.
A dynamic and evolving database
Aggregated from public sources and refreshed regularly. Contacts carry a verification status where possible, so bounces don't eat into your sample.
A sample that refills itself, without repeats
Save the search that describes your segment once. Sellvance pulls new matching companies as the experiment needs them, and never the same company twice.
Save the segment
The search from your hypothesis, kept as it is for the whole experiment.
Exclude everyone you've contacted
Point the rejected list at All leads and past experiments stay out.
Let the campaign set the pace
Autopilot pulls only as many companies as the campaign can email.
From search to experiment in one place
The database is where an experiment starts. Every company flows straight into the rest of the platform.
- Add to a segment in one click. Or let a saved search do it continuously.
- Qualify before anyone is emailed. AI enrichment checks each company against your hypothesis.
- Send and get a verdict. Qualified companies move into the experiment's campaign.
Why a precise sample gives a better answer
Targeting isn't about sending more. It's what makes the result readable.
One problem per segment
A broad list averages groups that want different things. A narrow one tells you about the group you actually described.
Fewer emails to a verdict
Against a 3% threshold, proving a true 10% takes about 66 sends. Proving a true 6% takes about 282. The sharper the segment and the offer, the cheaper the answer.
Nobody hears from you twice
A company answering your second email tells you nothing about your new offer. Excluding past contacts keeps every result clean.
