One Spark organizers say they are "humbled" and "blown away" by the growth of this years One Spark festival.

Sunday they announced that more than 85,000 people joined One Spark in Downtown Jacksonville on Saturday, bringing the estimated total for the first four days of the festival to more than 235,000 people. Last year an estimated 130,000 attended the five-day event.

They invited everyone to come out again for the closing ceremonies where around 3.5 million dollars of crowdfunding money will be awarded. More than 600 creator projects will continue to showcase their ideas in 77 venues throughout 20-square blocks on Sunday. Votes can be cast for creators until 3 p.m.

At the closing ceremony, which starts at 5 p.m., One Spark will announce the winners of $310,000 in guaranteed crowdfunds and cash awards. Eleven $10,000 checks will be handed out in addition to the crowdfund distribution and individual contributions.

Organizers say the top three finalists in each category will pitch live to Jurors “Shark Tank” style at the Community First Pitch Deck at Hemming Plaza. Jurors will award one $10,000 prize to one winner in each of the five categories. Winners will be announced at Sunday’s Closing Ceremony, and will also receive entry and airfare to One Spark Berlin.
