After the Sprint, you've got two paths
Stay hands-off with Management, or learn to do it yourself with the Cohort. Both start from the same fixed baseline.
Management
Best if you want this handled without thinking about it. Three tiers from £149/mo, month-to-month, cancel any time. You get ongoing monitoring and fixes; we own the skill.
Cohort
Best if you want the capability in-house. £1,200 one-off, 12 weeks, small group. You own the skill going forward; ongoing cost after that is just your tooling subscription, not a retainer.
Neither is wrong — it depends whether you'd rather rent the attention or own the skill.
