🇵🇹 FOUNDING STORY - The Origin of K2Crypto
The Story of Tiago and Rafael - Two Coders, One Vision
In 2017, in a small café overlooking the Atlantic in Porto, Tiago Alves and Rafael Duarte met to discuss a problem that obsessed them both:
“Why is crypto still so complicated for the people who need it most?”
Tiago, a security engineer with a background in applied cryptography, had spent years developing encryption protocols for fintech startups. Rafael, a blockchain developer and open-source contributor, was fascinated by decentralized systems and the promise of financial freedom through code.
Both were driven by the same frustration - that cryptography and blockchain knowledge were scattered, overly technical, and inaccessible to newcomers.
So, with laptops balanced between coffee cups and scribbled notes full of hash functions and tokenomics, they decided to build something bigger than a project - a platform to decode the crypto world.
That night, the idea for K2Crypto was born.
Named after K2, the world’s second-highest - and one of the most challenging - mountains, the name symbolized what they believed in:
“Reaching the summit of crypto knowledge requires skill, patience, and trust in your tools.”
They envisioned a knowledge hub where developers, investors, and enthusiasts could learn, explore, and build together. Over time, their mission expanded from technical tutorials to deep-dive research, crypto reviews, and AI-driven analysis - all while keeping education at the heart of the platform.
Today, Tiago leads K2Crypto’s cryptography and security division, ensuring accuracy and integrity in every article, while Rafael oversees the AI-driven market research, blending data with human insight.
Together, they turned a conversation in a Portuguese café into a global resource for crypto education - still guided by their founding belief:
“The future of crypto isn’t just code - it’s understanding.”
