Venture building for durable ideas.
Ten & Walker is a venture studio and intellectual-property platform. We originate and build selected ventures, steward brands and frameworks, publish through Ten & Walker Press, and make selective investments where we can add more than capital.
Based in Málaga, Spain · Working across markets
The right idea needs the right container.
Some ideas need a company. Some need an operator. Some need software, a marketplace, a book, a licensing structure, or more time before they should become anything at all.
Ten & Walker exists to give those ideas the right structure.
Our role changes with the work. We may originate a venture, build its first operating model, steward the underlying intellectual property, publish the idea, bring in an external operator, or participate as an investor. The objective is not to force everything into the same company-building template. It is to preserve what is valuable while giving execution to the people and structures best positioned to carry it.

Investment is one tool inside Ten & Walker. Ten & Walker is not an investment fund.
Ten & Walker Press is the publishing imprint of Ten and Walker SL.
It publishes systems-oriented nonfiction and other durable intellectual property where the work should stand independently of the ventures around it. The imprint provides an editorial home, rights structure, and distribution layer for ideas designed to remain useful beyond a launch cycle.
Its first title is The Human OS Manual by Oscar Trelles, publishing October 15, 2026.

The Human OS Manual
Why Self-Improvement Fails When You Ignore The System Underneath
A systems manual for understanding how energy, clarity, behavior, recovery, adaptation, and healthspan are shaped by one interacting human operating system.
Where we engage
Ten & Walker works across a deliberately mixed portfolio. The common denominator is not an industry label. It is whether better structure, ownership, intellectual property, or operating design can create durable value.
These are areas of existing work, not a mandate to manufacture ventures to fill categories.
Principles
Founder & Principal
Oscar Trelles is a Peruvian-American entrepreneur, systems thinker, and author of The Human OS Manual. Over more than two decades, his work has spanned advertising, strategy, market research, technology, cybersecurity, startups, and commercial leadership across the United States and Europe.
At Ten & Walker, he works across venture architecture, category design, intellectual property stewardship, publishing, and selective investment. The common thread is systems design: understanding how incentives, environments, narratives, and operating conditions shape what people and organizations can build, sustain, and become over time.
Selected Work
Ten & Walker’s role varies across the portfolio: owner, studio, investor, publisher, or IP steward. The structure follows the needs of the work rather than forcing every project into the same model.
Start a conversation
Ten & Walker does not operate as a general consultancy or accelerator. We work selectively where there is a clear venture, intellectual-property, publishing, operating, or investment reason to engage.
The most useful inquiries are concrete.
