## Steve Tulenko (person)

**Role in the source:** President of **Moody's Analytics**, who partnered with [[entity-rob-fauber|Rob Fauber]] to drive the AI transformation.

### Profile
Tulenko is the voice of the **build-vs-buy** thesis in the case: he emphasized applying **off-the-shelf models to proprietary data** rather than building foundation models.

### Attributed contributions in this vault
- The claim that advantage comes from application, not proprietary models: [[claim-proprietary-models-not-competitive-advantage]].
- The **'ready-to-use tools'** quote: [[quote-ready-to-use-tools]].
- The strategic logic behind the [[concept-ai-orchestration-layer]] and the contrarian [[contrarian-off-the-shelf-over-proprietary]].

### Enrichment note
Quoted in the HBR piece arguing that commercial LLMs are 'ready-to-use' tools and that the competitive edge lies in applying them to proprietary data.
