What PartySlate does
PartySlate is a Chicago-based, private event-planning marketplace platform founded in 2016 by CEO Julie Roth Novack and CTO John Haro. The platform connects individuals planning celebrations with a curated directory of venues and vendors across the United States, and has expanded structured category coverage to weddings, corporate events, birthdays, baby showers, fundraisers/galas, and bar/bat mitzvahs. The user-facing core product is a web-based marketplace where event planners browse 10,000+ venues, filter vendors by category (planners, photographers, caterers, florists, entertainers, rentals, and more), explore an idea gallery of over 4 million real-event photos, save favorites into personalized Idea Slates, and message vendors directly. The platform covers all 50 US states and has begun international expansion (e.g., Cabo San Lucas), with distribution driven primarily through SEO-optimized category and location pages.
The underlying technology is a standard web marketplace stack with no disclosed AI/ML, no native mobile app, no public API, and no documented proprietary algorithms beyond filtering and search. PartySlate Pro is offered as a separate professional-tier subscription for venues and vendors, providing advanced profile, showcase, and management tools; platform-level pricing for Pro is not publicly disclosed. Vendor-level pricing varies, with some vendors disclosing minimums (e.g., $4,000 entertainment, $2,500 event planning, $1,250 photography). The company has raised approximately $11.5 million in disclosed funding across nine rounds since 2015, with investors including Hyde Park Venture Partners, Great North Ventures, FJ Labs, HearstLab, Three Bridges Private Capital, Wavemaker Ventures, Dundee Venture Capital, Alumni Ventures, Halogen Ventures, InvestHER Ventures, JUMP Investors, Service Provider Capital, Right Side Capital Management, and Techstars. Headcount is reported at 11–50 employees.
