Who should pick which
- Facility manager of a 10-building commercial portfolioPick: Nectar Energy
Nectar Energy integrates with existing BMS (BACnet/Modbus) to automate HVAC and lighting, providing real-time dashboards, anomaly detection, and ESG reporting — critical for reducing energy costs and meeting sustainability targets.

- Sustainability officer targeting net-zero by 2030Pick: Nectar Energy
The platform automatically tracks carbon reduction and generates reports for GRESB/CDP (via the new ESG module launched May 2026), while predictive analytics help prioritize retrofits and efficiency upgrades.
- Revenue operations leader consolidating tech stackPick: Persana AI Sales and Voice Agents
Persana replaces multiple data subscriptions (Apollo, Clearbit, etc.) with one credit-based platform; CRM sync to Salesforce/HubSpot and API access reduce integration overhead.
