About

Most outbound is broken the same way. A founder hires an SDR. The SDR sends 500 generic emails. Open rates tank. Pipeline stays empty. Three months later, the SDR quits. Repeat. I spent the last 2 years figuring out why this keeps happening and what actually works instead. The answer: infrastructure, not headcount. For a UK recruitment agency, I built a 13-step automated system that finds, enriches, and contacts prospects while the founder focuses on closing. No SDR. No agency blasting 10,000 emails. Just a system that runs daily and surfaces the 3% of prospects ready to have a conversation. Results: 28 qualified opportunities. GBP 136K pipeline. 62% open rates. 665:1 efficiency ratio. Here is what I learned: generating opportunities is the easy part. The real challenge starts when your team picks up the phone. The best outbound system in the world means nothing if the sales process behind it is not ready. That is why I only work with teams that are prepared to close. What I actually build: - Signal-based targeting (job changes, funding rounds, hiring patterns) - AI personalization that sounds like a human wrote it - Multi-channel sequences (email + LinkedIn + calls) - Full pipeline infrastructure, built and managed end-to-end I run a boutique GTM engineering practice, working with 2-3 clients at a time. No templates. Every system is built from scratch for your market, your ICP, your workflow. If you run a recruitment agency in the UK and your outbound is either manual or outsourced to an agency that sends volume without strategy, we should talk. If you just want to see how I build these systems, follow along. I share the process openly.
