A former head of product who held leadership roles at Duolingo and Grammarly is challenging a core belief in tech. The veteran leader argues that years on the job can hurt decision-making when teams rely on old playbooks. The comments, made in a recent discussion about product strategy, come as software companies face rapid shifts in user behavior and AI adoption.
The central claim is stark and plainspoken.
“Experience can even become a ‘crutch.’”
That view goes against a common hiring bias for long resumes. It also raises a question for companies scaling fast: when does expertise stop helping and start blinding teams to better ideas?
Why Experience Can Backfire
Experience brings pattern recognition. It also brings habits that can narrow options. Product managers often lean on what worked before. In calm markets, that can be efficient. In shifting markets, it can block change.
Consumer apps, including language learning and writing tools, rely on constant testing. Tactics that sparked growth five years ago may stall today. Users now expect personalization, privacy, and instant value. AI tools can generate content in seconds. A step-by-step funnel from 2019 might not fit 2025 user expectations.
The former product chief’s warning suggests that accumulated wins can bias teams. A feature that once boosted retention can be overprotected. Leaders may favor safe bets that match their history rather than emerging signals.
Lessons From Testing Cultures
Duolingo and Grammarly built strong reputations around experimentation. Both invest in A/B testing, rapid iteration, and clear metrics. That culture thrives on humility. It treats each hypothesis as a draft, not a rule.
The caution about experience aligns with this ethos. It nudges leaders to let data, not memory, set direction. It also pushes teams to define what success means today, not last quarter.
- Retire playbooks that no longer predict outcomes.
- Design experiments that can disprove pet ideas.
- Rotate ownership to avoid local maxima in one area.
- Reward teams for killing weak bets early.
Balancing Veteran Insight With Fresh Eyes
Throwing out experience is not the point. The challenge is to use it without letting it dictate every choice. Seasoned leaders can frame problems faster and ask better questions. They can also spot failure modes before they spread.
To avoid the “crutch” effect, companies can pair veterans with newcomers on key projects. They can run premortems to map how a plan might fail. They can build metrics that reflect current goals, like session quality or time to value, not just sign-ups.
Hiring also matters. Teams should prize curiosity and clear thinking as much as tenure. Leaders can model this by changing course when evidence shifts. That signals that the best idea wins, even if it breaks with tradition.
Risks, Trade-Offs, and Industry Impact
There are trade-offs. Constant reinvention can cause thrash. Over-testing can slow delivery. Teams may lose the benefits of compounding knowledge if they reset too often. The sweet spot is disciplined learning with stable principles.
For consumer software, the stakes are high. AI-first features are changing core user flows. Writing assistants now suggest structure, tone, and citations. Language apps are mixing live practice with automated feedback. The move from static content to generative experiences demands fresh assumptions about value, trust, and safety.
In this context, the warning carries weight. When markets shift, the cost of clinging to past success rises. Companies that treat experience as input—not instruction—are more likely to find new growth paths.
What Leaders Can Do Now
Practical steps can keep experience from turning into drag on progress:
- Set guardrails: decide where to exploit known wins and where to explore.
- Timebox experiments and publish results internally.
- Write decision memos that state assumptions and expiry dates.
- Use cohort metrics to track if older funnels still work for new users.
These tactics convert experience into a library, not a leash. They keep institutional knowledge available while leaving room for change.
The former head of product’s simple line lands with force because it names a common trap. Experience is valuable until it calcifies. The teams that will thrive are those that challenge their own playbooks, measure what matters now, and stay open to being wrong. As AI and user expectations shift again, that habit may be the real advantage to watch.
