Put intelligence to work across energy
Acquisition & onboarding
Qualify leads from campaigns and partners. Coordinate contracts, supplier switching, move-ins, and consent through existing systems.
Retention & renewals
Identify churn risk from tenure, contracts, consumption, and service history. Prioritise retention, renewals, and win-back by customer needs and lifetime value.
Cross-sell & energy services
Match energy contracts, charging solutions, and business services to customer needs, eligibility, and consent. Coordinate follow-up across channels.
Customer & conversation intelligence
Connect conversations and account history to understand intent and sentiment. Help advisers explain bills and contracts, and share context with self-service.
Billing & revenue assurance
Reconcile meter readings, contracts, invoices, and payments. Flag errors, leakage, and overdue balances for review, then coordinate corrections and customer communication.
Commercial performance
Compare acquisition cost, conversion, retention, margin, and cost to serve. Prioritise profitable growth across customers, contracts, and channels using lifetime value.

How does AI support energy retailers rather than generators?
For an energy retailer, the work centres on customers, contracts, consumption, billing, service, and commercial planning. Connect these systems to improve customer journeys and support decisions about retention, offers, and operations.
What can AI demand forecasting help an energy retailer plan?
Forecast consumption across customer groups, compare scenarios, and assess how changing demand affects the plan. Select the prediction horizon, data, constraints, and actions around the retailer's responsibilities; this is distinct from controlling a generation asset.

For SK Energi, Langstack connected customer data and sales workflows above the existing billing system. The case describes commercial growth and more efficient agreement handling.
Read the SK Energi storyA security foundation for energy
Zero Trust makes access explicit, limited and subject to reassessment. Langstack’s identity and networking controls provide a foundation for applying these principles to applications, models and agents.
Explore Security- Explicit verification
- Verify identities and authorize access to each resource. Reassess access as context and security signals change.
- Least-privilege access
- Grant users, workloads and agents only the access their task requires. An agent’s decision to use a tool does not itself grant permission.
- Assume breach
- Design for the possibility that a workload or identity is compromised. Isolate workloads, limit lateral access, and monitor activity to help contain the impact.
“We’ve gained detailed insight across our commercial activities, and a committed, capable partner in Langstack.”
