What this question tests

Tests metrics strategy for a company expanding its category from a single feature to a broader platform.

Identify what changes with the platform shift: revenue and usage should increasingly come from products beyond core text to speech, like voice agents and music.
Build a platform breadth metric: revenue or active usage share by product line, tracked over time to show whether the shift is actually happening.
Add a cross sell metric: percent of existing TTS customers who adopt a second product, since platform success depends on expanding within the existing base, not just new logos.
Track a retention metric per product line, since a broader platform must prove each new line has real staying power, not just novelty usage.
Add a positioning guardrail: brand awareness or share of voice as an audio platform versus purely a TTS tool, tracked through customer or market perception.
Confirm with the interviewer whether the priority is proving platform breadth to the market or to internal stakeholders deciding where to invest next.

Uses cross sell rate from the existing TTS base as the core signal, correctly identifying that platform expansion success is proven by existing customers adopting more, not just new signups.
Tracks revenue mix by product line over time, showing the shift quantitatively rather than through anecdote or launch announcements.
Adds retention per product line, since new lines like music or agents need to prove durability, not just an initial adoption spike.
Includes a market perception metric, recognizing platform positioning is partly about how customers and the market categorize the company, not only internal usage numbers.

Tracking only new product launches or feature counts instead of actual usage and revenue shift across the base.
Ignoring retention on new product lines, celebrating adoption spikes that do not last.
No cross sell metric, missing whether the platform strategy is actually working within the existing customer base.

How would you know if a new product line was cannibalizing TTS usage rather than adding to it?
What would make you conclude the platform strategy was not working?
How would you prioritize investment across product lines using these metrics?
