You talk to the person doing the work.
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
- 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.
- 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%.
- 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.
- 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.
