Data, domains, warmup, sending, dialing and CRM in one stack — the only reason research can run before the send.

01The stack
Each of these is a product other companies sell on its own. Buying them separately is not just more expensive — it is why the research never reaches the message and the call never reaches the record.
DNS, SPF and DKIM configured for you, with free warmup on every mailbox from day one.
Search by title, seniority, industry or funding stage. Find the right email or mobile every time across 35+ industry-leading data providers, verified in the same step.
A sourced fact sheet per company and a fit verdict per campaign. Bad fits exit before the first send.
One sequence per person, written from the account's researched facts and paused everywhere the moment they reply.
A dialer built into the lead record, with local numbers you can buy in 130 countries.
Deals, emails, calls, LinkedIn touches and notes on one timeline, shared across the whole team.
02Infrastructure
The most fragile part of outbound is the part every sending tool leaves to you. Gripwise sells it, configures it, warms it and watches it.

Because charging for it makes no sense when we sold you the mailbox. A mailbox that is not warmed is a mailbox that does not deliver, and a mailbox that does not deliver makes the rest of the platform worthless.
03Finding people
Lists are assembled from live sources when you ask for them, not exported from a database that decayed eighteen months ago.

Then it gets qualified
Finding people is the easy half. Every account that comes out of this step is researched and ruled on before it is contacted — that is the part worth reading about.

06What it replaces
Where we draw the line
If we cannot find a fact with a working source, we do not invent one. The message falls back to your approved copy instead.
