A common failure mode when moving upmarket is committing to build every unique feature a prospect requests. This creates a "snowflake" roadmap that is not scalable. Successful companies learn to differentiate between true deal-blockers and nice-to-haves, maintaining strategic focus.

Don't overwhelm an enterprise buying committee by pitching all of your product's features. Instead, survey each member to find the 2-3 features that resonate most broadly. Focus all messaging and demos on just those features to create a clear, concentrated value proposition.

The moment you realize you have enterprise product-market fit is not just closing a big deal, but being able to enter a competitive proof-of-concept (POC) late and quickly become the front-runner. This proves your product's core value doesn't require extensive customization or a long sales cycle to demonstrate its superiority.

PMF isn't just users loving your product; it's when they're so invested they constantly pull you in new directions, demanding more features. This feeling of being overwhelmed by customer requests is a strong signal that you've built something truly valuable and are on the right track.

Initially, customers often "round down," focusing on missing features. A key sign of product-market fit is when they start "rounding up"—their faces light up in demos, and they imagine the product's future potential, forgiving current limitations because they believe in the core value.

Beyond usage and payment, the strongest PMF signal is when existing customers ask you to build solutions for other pain points. This shows they not only value your current product but have deep trust in your team's ability to solve their other, unrelated business problems, indicating true partnership.

Avoid the trap of building features for a single customer, which grinds products to a halt. When a high-stakes customer makes a specific request, the goal is to reframe and build it in a way that benefits the entire customer base, turning a one-off demand into a strategic win-win.

The ultimate test of product-market fit for an enterprise startup isn't the founder closing big deals. It's when the value proposition and sales process are so clear and repeatable that an average salesperson can successfully sell the product without the founder's presence in the room.

Product-market fit is confirmed through repetition. For Decagon, it was when the fifth and sixth customers independently described the same core problem, cited the same failed competitors, and expressed immediate willingness to buy, proving a repeatable market need.
