A seminar in San Francisco, at the heart of Silicon Valley

Immersion, innovation, management and tech discovery.

This is not a business trip. It is an immersion seminar designed by practitioners to change how you see business, technology and management. Over a week you are not a spectator: you work inside the Californian technology ecosystem and come to understand what tomorrow’s user will expect.

FAQ: California immersion — from founding project to innovative company

Yes. The programme is built to inspire and equip founders, including those still at seed stage. Meetings with company creators, visits to incubators and accelerators, and the sessions on business models are particularly valuable when a venture is still taking shape.
Young companies and startups get direct immersion in an ecosystem built to incubate innovation. We facilitate introductions, offer perspective on whether an innovative project is actually viable, and explore how business nurseries work. The informal mentoring and the first-hand accounts matter as much as the formal programme.
We go directly into how innovative companies get built in Silicon Valley: understanding disruptive business models, meeting founders who have succeeded, visiting active coworking spaces, and discussing founding projects and the realities of fundraising — including how business angels actually decide.
Yes. We regularly host students and recent graduates from business and engineering schools. For them it is a rare opportunity to test theory against practice, understand what innovation actually demands, and sharpen a project before committing to it. We can also arrange visits to university labs, at Stanford for instance.
The programme covers the range: conventional incubators, business nurseries supporting companies in their first months, and accelerator programmes for startups ready to scale. We look at how each structure actually supports a founder, and where each one stops being useful.
