Elsinore Ventures is a venture operating partner for AI and SaaS founders — and for the funds that back them.
Angus Birchall brings 10 years at Google, 8 at Meta, and 4 years building companies zero-to-one inside a venture studio to the GTM, growth, and revenue challenges that determine what happens next.
Full-stack growth marketing embedded in your team, not an agency on the sidelines.
Positioning, channel selection, messaging, and launch sequencing for AI and SaaS companies building their first commercial motion - or rebuilding a stalled one.
Audit your current growth model. Identify what's working, what's wasted, and what's missing. Then build the system — paid, organic, product-led, partnerships — structured into a coherent engine.
Pipeline architecture, funnel diagnostics, and CRM structure for teams that are closing deals but need the infrastructure to scale them.
Trusted by leading agencies worldwide.
“Elsinore didn't just run our marketing—they built a system we actually understand and can measure. For the first time, I know exactly where our leads come from.”
“We went from random marketing activities to a predictable pipeline. The ROI was clear within 90 days.”
Most businesses obsess over getting more traffic, but if your marketing funnel is leaking, every new lead is worth less. Here are five clear signs your funnel has a leak—and practical fixes for each stage, from landing pages to referrals.
Most B2B websites look credible but quietly leak pipeline every day. The problem isn’t design—it’s how your site speaks to buyers, guides them, and proves outcomes. Fix your messaging, navigation, CTAs, proof, and speed, and your website becomes a 24/7 revenue machine instead of a digital brochure.
Most agencies chase clients one at a time. The Elsinore approach is different: build a system that generates a predictable pipeline of qualified leads so your calendar fills itself.
Let's talk about where you are, where you want to go, and whether we're the right partner to get you there.
