FusionForce AI — Critical Action

Launch Automotive OEM Re-engagement Campaign — $94M ARR at Risk

847 Altair customers in the automotive OEM segment have not responded to Xcelerator migration outreach. At current ARPU, this represents $94M in annual recurring revenue at churn risk. Recommend launching a targeted re-engagement campaign within 7 days — assign dedicated Customer Success managers per account, with executive sponsorship from Siemens' Automotive VP.

FusionForce AI — Critical Action

Establish a Customer Experience Task Force to Arrest CSAT Decline

CSAT has dropped from 7.9 to 6.8 since deal close — a 14% decline driven by migration friction, dual-support model confusion, and product roadmap uncertainty. Recommend a dedicated CX task force with weekly NPS tracking and a 90-day "white glove" migration programme for the top 500 customers by ARR. Every 0.5 point of CSAT recovered correlates to ~$18M in reduced churn risk.

Accelerate Cross-sell: Altair Simulation to Siemens' 300K+ Customer Base

Cross-sell of Altair simulation tools to Siemens' existing industrial customer base is at 0% of $180M target — not yet started. FusionForce has identified 1,240 Siemens customers in aerospace and automotive with active simulation needs that Altair HyperWorks directly addresses. Recommend a joint sales motion with Siemens account teams — estimated pipeline value $42M in the next 2 quarters.
