In Silicon Valley, it is never too early to become an entrepreneur. Just ask 13-year-old Shubham Banerjee.
The California schoolboy has launched a company to develop low-cost machines to print Braille, the touch-based writing system for the visually impaired.
Last year, Shubham built a Braille printer with a Lego robotics kit as a school science fair project after learning that current printers cost at least 2,000 US dollars (£1,320) - too expensive for most blind readers.
After his Lego-based printer won numerous awards and enthusiastic support from the blind community, Shubham started Braigo Labs this past summer with an initial 35,000 dollars (£23,000) investment from his father.
In November, tech giant Intel Corp invested an undisclosed amount of venture capital in Shubham's start-up, making him perhaps the youngest entrepreneur to receive such funding.
