Portrait of Santiago Cardona Ortiz

I'm Santiago Cardona Ortiz. I work on my own, from Medellín, with brands in Colombia and abroad. From 2017 to 2025 I was co-founder and COO of Vieli, a 30-person studio: we delivered 100+ projects, all of them from referrals. From 2020 to 2026 I worked with silBe. I taught UX/UI design at CESDE for six years, and for Bancolombia I designed FIDI, a financial-education prototype built on WhatsApp videos.

Track record

  1. 2017–2025

    Vieli

    Co-founder & COO. A 30-person studio, 100+ projects, all from referrals.

    I set the strategy for every client, presented budgets and results to the owners, and turned the plan into briefs for the ads specialists and designers. When a client couldn't wait, I ran the Meta and Google Ads campaigns myself. I also built launches and funnels for creators with 845,000 to 1 million followers selling courses on Hotmart and Kajabi. The team worked remotely from Colombia, Argentina, Spain and the US.

  2. 2020–2026

    silBe

    Growth and marketing lead: funnel, conversion, app and subscription.

    I led marketing from the first launch, which brought in USD 400,000 and 5,000 subscribers in its first week (Forbes, 2021), to an app with 25,000 paying subscribers. I set the channels and the offer in five markets (Colombia, the US, the Middle East, Australia and Spain), tracked every sale by channel and by creator, and checkout A/B tests lifted conversion from 3% to 4%.

  3. 2019–2024

    CESDE

    UX/UI instructor.

    For six years I taught how to design digital products: user research, information architecture, prototyping and testing. Teaching made me explain clearly why a design decision works.

    Bancolombia · FIDI

    A personal-finance prototype built on short WhatsApp videos.

    I designed FIDI to teach personal finance through short videos sent over WhatsApp, the app people already open every day, instead of asking them to download another one.

  5. Since 2025

    Olmo

    Independent advisory.

    I work on my own, directly with the owners and teams of brands that already sell online. I advise on funnels, product, AI-powered systems and web, and I stay until it shows in the numbers. I also built Olmo Métricas, a free calculator for subscription businesses, and Olmo Cotiza, which turns a written scope into a proposal ready to send and is used by real clients.
