Outbound / RevOps / Growth infrastructure
21 Century Sales is a done-for-you outbound studio for B2B SaaS and agencies. We build the systems (Clay, Smartlead, Apollo, LinkedIn) and run them every day until your calendar is full.

Pick the engagement that fits your stage. All three plug into the same outbound engine. Only the surface area changes.
Foundation
from €3,500
We build the entire system from zero. Domains, inboxes, ICP, Clay enrichment, copy, sequences. You inherit a working machine in 21 days.
Engine
from €2,500 / mo
We run it. Every day. Lists, copy iterations, reply handling, meetings dropped on your calendar. You show up to the call.
Advisory
from €4,000 / mo
For teams with an SDR or junior already in seat. We architect the strategy, hire the talent, and own the number.
/ Manifesto
Most agencies sell volume. They blast 50,000 contacts, burn domains, and call deliverability a "channel problem." We don't.
21 Century Sales treats outbound like infrastructure. Tight ICP. Real signals. Personalized at the row, not the segment. Sent from warm inboxes that survive Google's next algorithm change.
Less spam, more conversations.
Fewer leads, more revenue.
/ The engine
Pipeline funnels, reply rates, deliverability, meeting velocity — all wired into a single source of truth. You see what we see, every day.
/ How it works
ICP workshop, signal map, value-prop teardown.
Domains, inboxes, Clay tables, copy v1.
Inbox warming, list scrubbing, micro-tests.
Full send live. First meetings booked.
/ From the trenches
"Rebuilt our entire outbound motion in three weeks. We went from 6 to 41 booked meetings a month. Same headcount."
"We finally stopped guessing. Pipeline is predictable for the first time."
"Day 21: first qualified meeting from cold. Day 60: €38k in new ARR."
"The Clay workflows alone were worth the engagement. They handed us a machine, not a deck."
/ Last call
30-minute strategy call. We teardown your current outbound and show exactly what we'd change in week one. No deck, no fluff.
