About us
FlatPeak integrates with electricity suppliers worldwide to provide real-time energy cost to any device or process enabling them to consume power when it’s cheapest and greenest. ⚡
We raised more than $5m from top-tier venture capital firms who supported industry-leading companies in digital energy, fintech and AI and have decided to take part in our journey. 🚀
Our tech stack:
- Languages: Javascript, TypeScript, Golang
- Datastore: MongoDB, Snowflake
- Infrastructure: AWS-Serverless, Atlas, Fly
- Monitoring: Sentry, Grafana, Datadog
- Business Intelligence: Tableau
Some of our current challenges:
- Product: We are shipping an average of a feature per week and tons of micro-improvements that compound in making our platform leading and valuable. We need to ensure our product stays sharp, free of clutter and no features are built for single-use.
- Machine learning: We have an enormous amount of transaction data, which we are using to provide better decisioning for our users. Predicting when energy cost will change or when a device will require more power is some of the problems we are tackling.
- Scaling: We connect to hundreds (and soon thousands) of datasources around the world in real-time. Millions of devices and processes rely on our data and algorithms. We need to keep FlatPeak running smoothly. This means building scalability in everything we do.
- Speed: In the rapidly changing energy industry what really matters is speed. We need to move fast adapting to the evolving market landscape while providing reliable solutions to your customers.
