Social Rewards, a social loyalty platform, has closed an oversubscribed seed round of angel funding totaling $600,000. The company, which has been mainly focusing on the travel and hospitality sector till now, also shared that it has achieved 80 percent market share of hotel casinos on the Las Vegas strip.

The platform helps in leveraging a company’s existing loyalty programme and turns it into a distribution platform via social media.

The platform provides a brand’s customers with loyalty points for engaging in social media activity via Twitter, Facebook, Foursquare, and YouTube.

Points may be earned, deposited, redeemed, donated, or transferred into a “bank” built on the Social Rewards platform. Social Rewards combines social media, affiliate marketing, and loyalty rewards to help companies identify brand advocates and increase social engagement.

Social Rewards has immediate plans to roll out to new markets and industries. The company was self-funded for a year with $250,000 from founders Joseph Morin and Mike Uesugi before raising any outside capital, and exceeded its original funding goal of $500,000.

The platform is now available in the US and Japan and is written in unicode, making implementation possible in any country or language.

“In our initial launch market of Las Vegas, we’ve already achieved an 80 percent market share of hotel casinos using the Social Rewards program on the Strip,” said Morin.

The company also announced new client wins including Caesars Entertainment with a global roll out to 52 resorts and casinos, and an expanded presence with MGM Resorts coming out of beta from their early adoption of the platform.

Two thirds of Social Rewards’ seed round was funded by members of Tech Coast Angels, the largest angel network in the US, including the TCA ACE Fund, the Angels’ new rapid accelerated funding arm. Other high-profile investors include Jeff Lapin, former CEO of Starwood Hotels, Stuart Larkins, part of the Performics founding management team, Kelly Perdew, previous LinkedIn advisor, co-founder & CEO TargetClose, and winner of Apprentice 2, Mi Ventures, and K5 Venture Partners.

Many of the company’s angel funding introductions were facilitated via AngelList, a social network of entrepreneurs and investors.
