About Kaiju
We are on a mission to clean the web of invalid emails, one list at a time.
From Zero to Global Scale
We started with a simple observation: the internet is cluttered with bad data. Invalid emails were costing businesses millions and damaging sender reputations everywhere.
We built Kaiju not just to verify emails, but to set a new standard for accuracy and speed. Today, we process millions of verifications daily, helping companies worldwide communicate with confidence.
Our Core Values
Transparency
No hidden fees. No "contact sales" for pricing. What you see is what you get.
Privacy First
We don't sell your data. We don't keep your lists. We verify and delete immediately.
Precision
We don't guess. If we can't verify an email, we tell you. We strive for perfection.
Speed
Time is money. Our engine is optimized for speed, processing thousands per minute.
Innovation
We constantly evolve our algorithms to stay ahead of spam traps and new email technologies.
Reliability
Count on us when it matters. Our infrastructure is built for high availability and uptime.
The Kaiju Initiative
We're not just another startup. We're a small team that has invested heavily in enterprise-grade infrastructure to deliver a service that rivals Fortune 500 companies.
20 Ryzen 7 Servers
Our verification cluster runs on 20 dedicated AMD Ryzen 7 servers, each optimized for parallel email verification. This allows us to process thousands of emails simultaneously while maintaining sub-second response times.
Dedicated IP Pool
Each server operates with dedicated IP addresses to prevent rate limiting and IP reputation issues. This infrastructure ensures consistent verification speeds and reliability, even during peak usage.
Battle-Tested Team
Our team built and scaled CompaniesData.cloud, managing millions of business records and API requests. We know how to build reliable, high-performance data systems.
