The Netflix Prize was an open competition for the best collaborative filtering algorithm to predict user ratings for films, based on previous ratings. The prize would be awarded to the team achieving over 10% improvement over Netflix's own Cinematch algorithm.
The team "Gravity" was the front runner during January—May 2007.
The leading position was achieved again in October 2007 in collaboration with the team "Dinosaur Planet" under the name "When Gravity and Dinosaurs Unite".
In January 2009, the two teams founded "Grand Prize Team" to initiate even wider collaboration that resulted in being one of the leading teams throughout 2009.
On July 25, 2009 the team "The Ensemble", a merger of the teams "Grand Prize Team" and "Opera Solutions and Vandelay United", achieved a 10.10% improvement over Cinematch on the Quiz set.
On September 18, 2009, Netflix announced team "BellKor's Pragmatic Chaos" as the prize winner, and the prize was awarded to the team in a ceremony on September 21, 2009. "The Ensemble" team had in fact succeeded to match the winning "BellKor" team's result, but since "BellKor" submitted their results 20 minutes earlier, the rules award the prize to them.
In 2009 and 2011, Gravity R&D got 2 rounds of investments from include Hungarian institutional strategic investors, Wojciech Uzdelewicz (an all-star analyst at Wall Street according to hedge funds, former Managing Director of Duquesque Capital), and the financial investor PortfoLion.
Gravity R&D introduced in 2010 RECO, its cloud-based SaaS personalization solutions for online businesses (e-commerce, market places, classified media, publishers, etc).
Gravity R&D extended its product portfolio in 2015 by introducing its automated, turn-key recommender system YUSP for small and medium enterprises (SMEs).
In 2016 the firm expanded internationally and established new practice areas.
Through its own subsidiary called Gravity Bricks & Mortar, the company is developing and providing personalization and recommendation solutions to Retail and Supermarket Chains, Retail Banks and Telecommunications companies worldwide by closely cooperating professionally and commercially with its strategic partner Deloitte Hungary in the joint sale and implementation of the above mentioned solutions to whom it may be of interest.
