Sense Energy

Electronics

Sense Energy

Sense's mission is to make all homes intelligent by keeping people informed about what's happening in their homes and helping to make them safer, more efficient, and more reliable. Sense was born from the simple idea that people should know what's happening in their homes. We track calories, footsteps, mpg's yet we know so little about the place where we spend so much time. Energy efficiency and home automation begin with information. We built the Sense home energy monitor to provide people with information about their homes in the simplest, most helpful way possible.

BlockJoy

Blockchain

BlockJoy

BlockJoy allows you to deploy and run your own blockchain nodes on any infrastructure you choose. It started as a project to manager staking with friends and family. We built advanced tooling to optimize validator management for teams of two. But, due to the sheer difficulty of installing and running nodes, our little VaaS company grew crazy fast. We quickly realized that VaaS can’t work for a network because it centralizes control. We turned our platform into a SaaS tool so that anyone could launch and run their own node with full control over where and on what infrastructure it runs. Now, network operators can run their own nodes; BlockJoy just takes the headaches away.

Mainstay

At Mainstay, we believe one conversation can spark a brighter future. Our Engagement Platform makes it easy for colleges and businesses to start and measure conversations that drive action at scale. From our rigorous research methods to our Behavioral Intelligence framework — everything we do is designed to help people take the next step toward achieving their goals.
