Tech is infamously ageist. It favours ambition over experience. Ideas over achievements. And novelty over history.
These 30 youngsters are making a name for themselves all before hitting the age of 30.
We believe that in the next few years they will be taking over Silicon Valley.
Here they are, presented in descending order of age.
Occupation: Founder/CEO of Facebook
Why: We're pretty sure this one is self-explanatory. But it's not just about Facebook: since persuading 1.2 billion people to join the social network, Zuckerberg has become an aggressive acquirer of both small apps like Glancee (for location sharing) and giant businesses like WhatsApp.
Occupation: Founder/CEO of Walker & Company
Why: Walker left Foursquare to launch his own startup and has already snagged $US2.4 million of backing. Walker & Company sells razors and shaving cream for black people online and is currently run by two employees.
Occupation: Co-founder of Asana
Why: If cofounding Facebook wasn't enough to convince you, Dustin hasn't slowed down, working on Asana (an app to foster teamwork without email), Good Ventures (a philanthropic foundation), and Vicarious Systems (which is developing machine learning software based on how the human brain works, starting with a visual perception system). Asana grabbed $US38.2 million in funding and employs 80 people; Good Ventures has secured at least $US55 million in funding; and Vicarious Systems has secured $US60 million in funding and employs six people.
Occupation: Co-founder of Causes

Occupation: Former Executive Director of Girls Who Code, currently a consultant
Why: She is working hard to change the gender break-down of the tech world. Girls Who Code works to educate young girls and inspire them to get involved in computing fields to level out the gender inequality in the industry. More recently she struck out on her own as principal at Kristen Titus Consulting, 'advising nonprofit and for-profit clients alike in the areas of strategic planning, management, fundraising, and communications.'
Occupation: Founder/CEO of Quora
Why: The Q&A company he started is valued at $US900 million, employs 90 people, and has secured $US141 million in funding. And if that wasn't enough, he also was one of the early guys at Facebook.

Occupation: President of Y Combinator/Cofounder of Loopt
Why: He's one of the guys who decides which startups get money. This is after he gave his own startup, Loopt, a try with a location-based social networking app. Before being acquired by Green Dot Corporation, Loopt had secured $US39.1 million of funding.
Occupation: Founder of Pebble
Why: Migicovsky's smartwatch is now probably the most-watched wearable tech brand, after starting as a kickstarter project a few years ago. Pebble has raised $US25.7 million in funding and has 35 employees.
Occupation: Founder/CEO of Tumblr

And SCVNGR has secured $US40.8 million in funding thus far.
