When to choose LUMOS vs StackAdapt (and when to walk away)
Choose LUMOS if
- Target ICP & Stack Fit: You operate as B2B Marketing and Growth & Revenue Teams requiring a Cloud SaaS Platform deployment for AI Programmatic Advertising.
- L3 Architecture & Defensibility: LUMOS builds a differentiated programmatic AdTech moat by uniting real-world physical location intelligence, Digital Out-of-Home (DOOH) inventory planning, cross-screen mobile retargeting, and Seed funding led by Claremont Capital.

Walk away from LUMOS if
- Walk away if you require transparent self-serve monthly billing or your budget ceiling is under $1,000/mo (LUMOS requires sales-gated custom quoting).
- Walk away if your workflow cannot tolerate primary operational trade-off: In practical enterprise deployments, the primary trade-off is that geospatial audience modeling and cross-device offline-to-online retargeting depend on regional location-signal density and local privacy regulations, which can vary across international markets.
- Walk away if functional scope boundary is a deal-breaker for your team: LUMOS is not built for B2B cold email outbound sequencing, generative text blog writing, or inbound customer support ticket automation.
Choose StackAdapt if
- Target ICP & Stack Fit: You operate as B2B Marketing & GTM Teams requiring a SaaS Platform deployment for AI Programmatic Advertising.

- Walk away if your workflow cannot tolerate ad spend floor needs: Real-time bid models need enough ad views and conversions to learn. Small brands with very low monthly budgets may struggle to train multi-channel models.
- Walk away if cross-channel attribution gaps is a deal-breaker for your team: Measuring lift across non-clickable upper-funnel channels like CTV, audio, and DOOH alongside web ads gets tricky when household ID graphs have gaps.
