HubSpot has emerged as the benchmark for build vs buy ai excellence in MarTech. Their investment of $50M+ in build vs buy ai capabilities between 2024-2026 generated measurable improvements: ROAS up 32%, CAC improved by 25%, and Attribution Accuracy enhanced by 18%. Their approach prioritized cross-functional integration over isolated deployments.
However, Adobe is pursuing a contrarian strategy that may prove more effective long-term. Rather than heavy upfront investment, they deployed build vs buy ai incrementally through 12-week cycles, each with mandatory ROI validation.

Looking ahead, three factors will determine build vs buy ai winners in MarTech: speed of implementation (first-mover advantages are real and durable in this domain), depth of integration (surface-level adoption produces surface-level results), and measurement rigor (companies that cannot quantify build vs buy ai impact will inevitably underinvest).
Ehsan's Analysis
Adobe generated $28M in incremental revenue from build vs buy ai in 2025, while HubSpot spent $50M on it with unclear returns. The difference: Adobe treated build vs buy ai as a revenue feature customers pay for, while HubSpot treated it as an internal efficiency play. In MarTech, build vs buy ai is a product strategy, not an operations strategy. Companies that monetize it directly will fund their investment; those that treat it as cost reduction will perpetually under-invest.
