Be brave and deliver and this will happen.
Important fact in my last 2 years just happened - last week. Almost two years ago I have started building K2 Digital Ventures which helps large organizations to innovate with audacity and a speed of startups. One of our customers is Shell. Huge global company with many business units, business lines and clusters. Thousands of people. Many markets. All continents.
The project we work on together is, generally speaking, building a startup in and with large organization. After 18 months of hard work, and we are still not done, we gave a public speech together. The project became public. I love it. I love it. It is a proof that startups way of building business works in large organizations.
If you are brave enough, push things forward every day and execute like crazy this happens......
