# Tecogen touts Cloudsmart data center testimonial for InVerde cogeneration; no financial figures disclosed

## Summary
- Cloudsmart Inc. CEO Robyn Sullivan says the Connecticut Tier 3, SOC 2 cloud/AI data center has been generating its own power with Tecogen's InVerde for 'a few months.'
- Sullivan claims Cloudsmart 'cut our electric bills substantially,' giving it an edge on energy costs versus other local data centers, and says the unit has run reliably and hands-off.
- Tecogen CEO Abinand Rangesh said the testimonial shows the products meet data center demands and that such 'real-world proof points' are needed to convert its data center pipeline to orders.
- Filing gives no contract value, unit count, revenue contribution, savings percentage, or order backlog figure tied to the Cloudsmart installation.
