Product Strategy and North-Star Metric for a Shared In-House AI Agent Platform
Company: Netflix
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
You are the product manager for an internal AI platform: other teams across the company use it to build their own AI agents. Answer in two parts.
### Clarifying Questions
- How far along is the platform: are teams already running agents on it in production, or are most still building their own stacks or using outside tools?
- What does the platform provide today: model access only, or also connectors to internal systems, permission handling, evaluation and monitoring?
- Who builds on it: engineering teams shipping customer-facing agents, internal-tools teams automating operations, or non-engineers in business functions?
- Is using the platform required by leadership, or does it have to win teams over against building their own?
### Part 1 — Strategy
What is your strategy for the platform: who it serves first, what it does for them, and how it gets adopted?
```hint Why not build it themselves?
Any team can call a model API and wire up its own tools. Think about what the platform can offer that a team cannot easily get alone, and at which step between a working prototype and a trusted production agent that matters most.
```
#### What This Part Should Cover
- The platform's purpose for the company and the builder segment it serves first, with the reasoning
- The biggest obstacles builders face and which one the platform attacks first
- What makes the platform hard to replace, and the plan for adoption
### Part 2 — The one metric
If you could own only one metric for the platform, which would it be, and why that one?
```hint Activity is not value
API calls, agents created and registered developers can all grow while nothing useful happens. Look for a number that moves only when agents built on the platform do real work well.
```
#### What This Part Should Cover
- A precise definition of the metric: what counts and what does not
- Why it beats the obvious alternatives
- The supporting metrics and guardrails that keep it honest
### What a Strong Answer Covers
- A strategy and a metric that follow from each other
- The realities of an internal platform: other teams as customers, cost paid centrally or charged back, and competition from building in-house or adopting outside tools
- Security, permissions and data access for agents that act on internal systems
- Sequencing: what ships first and how the platform earns adoption before broad rollout
### Follow-up Questions
- Your metric is climbing, but nearly all the growth comes from one team. Is the strategy working?
- A large team wants to use an outside agent framework instead of your platform. How do you respond?
- Model spend on the platform doubles in a quarter. How do you tell whether that is good news?
Overview: A product strategy question for the PM of an internal platform that company teams use to build AI agents. It asks for a strategy for the platform and the single metric you would own, testing segment choice, adoption planning, and how well a candidate defines and defends one measure of success.
