Case studies.
The proof of the playbook isn't in a case-study slider. It's in a single long-form telling of the work I've actually done. The headline credential is below, with more to come as the consultancy publishes them.
More case studies are being written. By the way, if you'd like to be one of them, the audit form is the starting point.
※If you want me to look at your specific site against the same playbook we ran at CoLaz, the audit is free and you don't need a call to start it. Send the URL over — let me know what's going on.
