The rows your GTM team can actually use
Not a sponsor PDF. Not scraped badges. A structured dataset your team can filter, route, enrich, and act on before the conference window closes.

Verified outcomes
Attendee data that outpaces other GTM channels
Verified conference campaigns delivered these outcomes while outperforming typical cold outbound, paid social, and broad-intent lists on reply and meeting conversion—because the motion starts with confirmed attendance, attendee context, and refresh cadence through the show.
95%
Attending accuracy
Verified against observed event participation—precision cold lists and rented intent audiences rarely match.
66%
Reply rate
From outreach using attendee-specific context—well above typical cold outbound on comparable touches.
52%
Meeting booking rate
For qualified replies converted into scheduled meetings—ahead of booking rates we see from paid social and generic nurture paths.
6 hours
Refresh frequency
New attendee signals refreshed throughout the event window—faster than weekly enrichment cycles common in outbound stacks.
What You Get
Conference datasets built for action, not decoration
Company attendee lists
Organizations represented at the event, normalized with firmographics and routing fields.
People-level attendee lists
Names, roles, seniority, departments, and contact fields where available.
ICP-shaped filtering
Narrow the dataset by segment, account profile, function, title, geography, size, or campaign objective.
Contact enrichment
Add work email, LinkedIn, and phone fields based on your outreach motion.
Conference campaign briefs
Turn a raw attendee universe into priority account lists for sales, marketing, and partnerships.
Refreshes through the event window
Support pre-event planning, on-site changes, and post-event follow-up.
Who Uses It
One conference dataset, multiple GTM motions
Sales teams
Prioritize accounts, book meetings, and route prospects to the right owners before the show.
Marketing teams
Build segmented invite lists for dinners, side events, webinars, and post-event campaigns.
Partnerships teams
Identify partner prospects, ecosystem companies, and people already gathering in one place.
Sponsors and exhibitors
Know which accounts to target on-site instead of waiting for booth scans after the fact.
Founders and operators
Turn expensive conference travel into a focused list of people worth meeting.
How It Works
From conference brief to outreach-ready data
Tell us the conference and target market
Share the event, your ICP, target roles, fields, and campaign objective.
We build the attendee dataset
We assemble company and people-level records, enrich fields, and structure the list for your workflow—sourced from public web activity, event ecosystems, and enrichment workflows.
Your team acts before, during, and after the event
Use the dataset for meeting-setting, on-site prioritization, dinners, partner campaigns, and follow-up.
Why Impossible Data
Most conference lists arrive too late. We make them useful while the event still matters.
Before the show
Start outreach while calendars are still open.
During the show
Route the right accounts to the right people on-site.
After the show
Follow up with structured context instead of a cold CSV.
Built around your ICP
Every list starts from your market, not a generic attendee universe.
