Oscar Trelles is the founder of Breathing Flame and author of The Human OS Manual. He works at the intersection of human performance, organisational systems, and technology, examining how energy, attention, recovery and decision quality are shaped by the conditions in which people live and work. His career spans two decades across advertising, strategy, market research, startups, cybersecurity, and global commercial leadership. Today, he combines that operating experience with systemic coaching and applied human performance to develop practical frameworks for strengthening human capacity as organisations adopt increasingly capable AI systems. He is based in Málaga, Spain.
