Empowering Innovation, Eliminating Compliance Barriers

At TANDMM, we believe that compliance should fuel innovation, not slow it down. Startups and research institutions are building the future, yet navigating the complexities of security frameworks, compliance mandates, and enterprise procurement often becomes a bottleneck. We are building Day1 to solve this problem, delivering pre-engineered, audit-ready cloud infrastructure so that companies can move fast, meet compliance requirements, and unlock enterprise sales and research funding without months of delays.

We exist to accelerate the speed to funding for organizations in enterprise, highly regulated and government industries by eliminating compliance and security as a friction.

Whether you’re a SaaS startup trying to close your first enterprise deal or a research institution securing limited government funding, compliance is non-negotiable. With Day1, we provide a fully compliant cloud environment from day one, so you can focus on innovation while we handle the complexities of security and compliance.
