# Coaching/Clarity Call w/ Alun with Alun Da Silva

> Alun Da Silva — Clarity Call I'm a marketing systems consultant with 13+ years of experience building marketing systems for SaaS and tech companies — from solopreneurs to Fortune 500s. I work with founders at £10k–£50k MRR whose marketing has become messy, ad-hoc, and dependent on them being in the room for anything to move. In a focused four-week engagement, I help them rebuild it into something repeatable, AI-powered, and free of the founder as the single point of failure. This call is 30 minutes. We'll identify which of the three core marketing problems is costing your business the most right now — and you'll leave with a clear next step, whether we work together or not. No pitch deck. No pressure.
