Why we built it.
Most sales email is written before anyone has looked at the company it goes to. We built SYNC to do the looking first, and to stay silent when there is nothing to say.
Where we are.
SYNC is in early beta. We run it on our own outbound and with a small number of client teams, and we publish what we measure, including what fails, under Research.
How we work.
- 01
Measure before we claim.
Numbers on this site come from our own data. Where we do not have one yet, we say so.
- 02
Rules live in the product.
A promise we make here is enforced in SYNC, not a line in a brochure.
- 03
Europe first.
Dutch outbound in Dutch, from your own mailbox, with workspace data stored in the EU.
Our Europe-first approach - 04
Less, finished.
One job done completely beats ten done halfway.
