We just raised — why not just hire a CMO now?
Because you don't yet know which channel or offer works, and a £150k hire made on a guess is expensive to get wrong. WSS names the constraint and proves the channel first, so your first senior marketing hire (if you make one) walks into a system, not a blank page.
We don't have any marketing hires at all yet — is that a problem?
No — it's the exact stage this is built for. The engagement installs the system with whoever you have (including just you), then hands the weekly rhythm to whoever joins next.
How is this different from an agency?
Agencies are the right call once the channel plan is clear and you need production capacity. WSS works one level up — naming the bottleneck, aligning channels, and installing the decision rhythm your team (or your agency) runs inside. Many founders need both, in that order.
