Overview
KingSumo
KingSumo helps you turn strangers into subscribers by running viral giveaways that people actually want to share. Instead of paying for expensive ads, you can offer a prize and let your entrants do the marketing for you. The platform uses a unique referral system where users earn extra entries for following your social profiles or inviting their friends to join the contest.
You can set up a professional giveaway page in minutes without any coding or design skills. It handles the heavy lifting by tracking referrals, verifying social media actions, and automatically picking winners. Whether you are a blogger, podcaster, or e-commerce store owner, you can use these contests to build a massive, engaged audience quickly and affordably.
SourceScrub
SourceScrub is a specialized deal-sourcing platform designed to help you find and vet privately-held companies that aren't yet on the radar of your competitors. Instead of relying on static databases, you get access to a dynamic engine that tracks millions of companies by aggregating data from thousands of sources like trade show attendee lists, executive profiles, and industry awards. This allows you to identify high-growth prospects before they officially hit the market.
You can manage your entire deal funnel within the platform, from initial discovery to outreach and tracking. It solves the problem of fragmented data by centralizing company signals, ownership details, and contact information in one place. Whether you are in private equity, venture capital, or corporate development, the tool helps you build a data-driven pipeline and make more informed investment decisions based on real-time market movements.
