Rino Sinčić
Co-Founder, Technology
Rino builds and maintains the technology behind LeadVine — from client websites to the internal systems that power the agency.
Rino is the technical backbone of LeadVine. He architects and builds every client website on the Astro + Sanity stack — a setup he chose specifically because it ships fast by default, not fast after a month of optimisation. Speed, crawlability, and clean SEO fundamentals aren't features he adds on; they're the starting point.
Before LeadVine, he worked alongside Simon in the US addiction treatment space, building the sites and tracking infrastructure behind six-figure-a-month ad campaigns where a broken conversion pixel or a slow-loading landing page meant burning tens of thousands in wasted spend. That environment doesn't tolerate sloppy engineering. It's where he sharpened his approach: build for performance first, measure everything, and never ship a site that can't prove it's working.
At LeadVine he owns every build, plus the internal tooling that keeps the agency running — the content pipelines, the build systems, and the integrations that keep client data clean and campaigns properly tracked. Every site gets the same three-question test before it goes live: will it rank, will it load fast, and will it convert? Everything else is secondary.
