INSIGHT

Some Success Is Not Product Market Fit

Some revenue and satisfied customers can mask a lack of true product–market fit.
Teresa explains early fans can keep a product stable yet too small to grow or scale into the impact you want.

INSIGHT

Flatlining Products Steal Discovery Time

Stable, flatlining products quietly consume discovery capacity and block new opportunities.
Teresa notes every hour maintaining a limp product is an hour not spent running experiments to find a higher-growth product.

ADVICE

Add A Sunsetting Column To Your Board

Add a sunsetting column or regular review so teams can flag features or products for retirement.
Petra recommends using that column to start reallocation conversations and reduce surprise when decommissioning is needed.

What this episode covers:

Why some traction can be more dangerous than no traction at all
The difference between early fans and real product–market fit
How “stable but not growing” products quietly drain discovery capacity
Why killing profitable products can be the right strategic move
The org and team implications of sunsetting products
How to create space for what’s next—without framing it as failure

Key moments & themes:

00:00 – Why “kill your darlings” matters
Teresa introduces the idea of letting go of products that feel successful but aren’t delivering the impact or growth you need.
04:30 – The dangerous middle ground
Products that are profitable and liked, but not growing, often escape scrutiny—and quietly block better opportunities.
09:30 – The opportunity cost of “okay” products
Every hour spent maintaining a flatlining product is an hour not spent discovering something better.
14:30 – Sunsetting in product organizations
Petra explains why dedicated teams and org design make decommissioning products especially hard—and why leaders need explicit sunsetting conversations.
19:00 – Real examples of killing revenue streams
Teresa shares concrete decisions from her business, including shutting down a popular Slack community and cutting deep-dive courses that made up 40% of revenue.
28:00 – Designing for the right customers
Why Teresa intentionally limits access and pricing to work with customers who show agency and commitment.
33:30 – Burn the ships (on purpose)
Letting go of short-term revenue to make space for experimentation and future growth.
38:00 – Making sunsetting easier
Practical frameworks product leaders can use:
- Regular portfolio reviews
- A visible “sunsetting” column
- The Horizon (H1 / H2 / H3) model
- Making portfolio decisions one level above teams
46:00 – Normalizing product lifecycles
Successful products don’t fail—they run their course. Markets change, and endings should be expected, not stigmatized.

Takeaways for product leaders:

Product–market fit isn’t binary—and “some success” can be misleading
Sunsetting is a portfolio decision, not a team failure
Teams shouldn’t be punished for working on products that reach the end of their lifecycle
If experimentation isn’t in your DNA, killing products will always feel traumatic
Making space is an intentional act—not a passive one
