Purdue University is seeking competitors to participate in three Lilly Endowment-sponsored business plan competitions.

Each competition offers at least $50,000 in prizes — $25,000 for first place, $15,000 for second and $10,000 for third. Local sponsorships may increase prize amounts and provide professional business and legal services for the winners.
