Zefr is a video advertising company that creates targeted video ad placements with it's unique and proprietary technology. With our custom packages, we leverage both technology and human review to selected individual videos, ensuring brands can safely and effectively scale their video ad campaigns. Why the name Zefr? Before Venice became “Silicon Beach” it was the grimy paradise of the 1970's Zephyr skate team. The Z-boys were a group of broken-home-punks that pioneered today’s skate culture. They did more than just push the physical boundaries of the sport—they created the culture that defines Venice today. At Zefr, we embrace the Z-boy’s drive for innovation, performance, and pushing boundaries. Our motto? Go Big. Go Fast.

Trading ZEFR Stock
How to invest in ZEFR stock?
Accredited investors can buy pre-IPO stock in companies like ZEFR through EquityZen funds. These investments are made available by existing ZEFR shareholders who sell their shares on our platform. Typically, these are early employees who need to fund a life event – house, education, etc. Accredited investors are then offered the opportunity to invest in this stock through a fund, like those used by hedge funds serving large investors. While not without risk, investing in private companies can help investors reach goals of portfolio diversification, access to potential growth and high potential return.

An Express Deal allows you to sell your allocation of private shares in a given private company to another investor on EquityZen's marketplace. See more information on Express Deals and pre-IPO exit information.
