Glendower Advisory
Post-Sales Revenue Growth for Series B and C SaaS
The problem
You'll recognise at least one of these. NRR flat despite CS investment. PS margin scrutinised but misunderstood. Coverage models that leave your highest-potential accounts underserved. Sales, Services and Customer Success operating as sequential handoffs rather than a coordinated revenue system. Or perhaps post-sales is growing fast and you're not yet sure how to build it for the long term.
The fix isn't more headcount or a new playbook. It's understanding exactly where revenue is leaking — or being left on the table — and fixing it in the right order.
What we do
Glendower Advisory works with Series B and C PE-backed and founder-led B2B SaaS businesses ready to treat post-sales as a revenue system.
We offer two things:
A forensic diagnostic of your post-sales revenue system — interviews, data, documentation — delivered as a board-ready report with a prioritised intervention roadmap. Fixed fee. Four weeks. £18,000. If you proceed to a fractional engagement within 30 days, the diagnostic fee is credited against the first month.
Fractional leadership to implement the fixes — from £9,600/month at 2 days per week, flexing to 3 days as scope warrants. A typical engagement runs three months: diagnostic phase into implementation phase, with a clear deliverable at each stage.

I work with a small number of Series B and C SaaS businesses at any one time — so fit and timing matter to me as much as they do to you. The diagnostic is £18,000, four weeks, fixed scope, with a clear deliverable at the end. If you proceed to fractional leadership within 30 days, the diagnostic fee is credited against month one.
