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.
Prefinery

It handles everything from lead capture and automated email sequences to reward delivery and fraud prevention.
You can integrate the platform directly into your existing website or use their hosted landing pages to start collecting leads in minutes. It is designed for startups, SaaS companies, and game developers who need to manage thousands of beta testers or early-access signups. The platform provides deep analytics so you can track which influencers are driving the most traffic and optimize your launch strategy accordingly.
