Introduction
Achieving product market fit is a pivotal milestone in any startup’s journey. It’s when your product resonates deeply with a specific audience and demand starts to pull you forward. But many founders misread early signals, chase false positives, or scale prematurely.
Andy Rachleff, co-founder of Benchmark Capital and Wealthfront, outlines four key mistakes that consistently derail startups trying to find product market fit. This post unpacks those mistakes with real-world startup examples — and shows you how to avoid them.
Mistake 1: Prioritizing Well-Known Customers Over Desperate Ones
“You should not go after the big market first. It’s the exact opposite of what everyone tells you.” — Andy Rachleff
The Pitfall: Founders often chase logos — believing a big brand customer will validate their startup. But these customers are often slow, risk-averse, and don’t have urgent pain.
Real-World Example: Quibi raised $1.7B and signed big media deals — but never found a core audience with a desperate need for its short-form video platform. It shut down within 6 months of launch.
The Fix: Prioritize early adopters with hair-on-fire problems. They adopt faster, give better feedback, and don’t need convincing.
Mistake 2: Iterating on the Product Instead of the Audience
The Pitfall: When a product flops, founders often default to adding features. But what if the issue isn’t the product — but the people you’re building it for?
Real-World Example: Frankly.me, a Q&A social platform in India, iterated multiple times but never clicked with its audience. The idea wasn’t necessarily bad — the market fit was just missing.
The Fix: Re-segment. Ask: who finds this product obvious and urgent? Test the same product with different customer types before rebuilding it entirely.
Mistake 3: Pursuing Growth Before Delivering Value
The Pitfall: Scaling too early — with ads, partnerships, PR — can disguise the fact that users don’t actually stick, pay, or tell others.
Real-World Example: Homejoy expanded rapidly across cities but struggled with retention due to inconsistent service. Despite high growth metrics, it failed in under 2 years.
The Fix: Nail retention, engagement, and repeat usage first. Growth before value is a trap. Product market fit shows in behavior, not buzz.
Mistake 4: Treating Product Market Fit as a One-Time Achievement
The Pitfall: Founders sometimes treat product market fit like a finish line. But PMF can fade as markets shift and new competitors enter.
Real-World Example: Pebble was an early smartwatch hit on Kickstarter. But as Apple and Samsung entered, Pebble lost its edge and failed to evolve fast enough.
The Fix: Treat product market fit as a system, not a status. Build recurring validation into your strategy. Your PMF pulse should evolve with your market.
Bonus: Don’t Confuse Problem/Solution Fit With Product Market Fit
You’ll hear, “We love the idea!” or “We’d use something like this…” But that’s often just validation of the problem — not your solution.
The Fix: Measure usage, retention, activation. Product market fit shows up in behavior, not compliments. Don’t confuse applause for adoption.
Product Market Fit Is a Moving Target — Not a Trophy
Most startups fail not because they built the wrong thing — but because they chased the wrong signals. They built for the wrong customer, scaled too early, or stopped evolving once they had early wins.
True product market fit is dynamic. It requires iteration, humility, and obsessive customer understanding. Don’t just build. Validate.
