John Glasgow spent over a decade as the end customer of enterprise accounting software — at Adobe, Invoice2Go, and Bill.com — before deciding to build the ERP he always wished existed. After Invoice2Go was acquired for $625 million, he applied to Y Combinator with a newborn at home and a single conviction: the incumbents were 25–30 years old, the pain was acute, and nobody was building for the modern tech company. Campfire, the AI-native ERP for growing tech companies, was the result. Customers like Replit and Posthog are scaling on it today.

Topics Discussed:

Why deep category experience — not just founder energy — gave John his edge at YC

Getting to paying customers within 30 days of starting the program

How to identify and close early adopters who pay before the product is ready

Two years of solo founder-led sales as the only AE and solution consultant

Why the first AE hire came from an incumbent, not a startup

Building a credible brand in a category starved of creativity

The daily LinkedIn content engine that now drives 80% inbound pipeline

GTM Lessons For B2B Founders:

The best early customers are strangers, not friends. John's network opened doors, but his most valuable early customers came from cold LinkedIn outreach to people he had never met. One replied that his financial reporting was "so bad" he was willing to meet weekly for an hour — no compensation, no equity — just to help build the right product. Warm intros from your network are useful, but a stranger paying for a rudimentary product and demanding you meet weekly is the real PMF signal. Optimize for that.

If a prospect says "once you ship X, we'll buy" — flip it on them. Don't build to the condition. Ask them to sign now with a contract contingent on that feature shipping. If they won't, they were never serious. John saw founders repeatedly fall into the trap of waiting for one more feature or one more logo before going to market. The "not ready yet" excuse almost always belongs to the founder, not the product.

Narrow your ICP to the point it feels uncomfortable, then go deeper. Campfire landed on the 50–150 employee Series B/C tech company and refused to move until that cohort was truly happy. In a category where NetSuite and Sage Intacct technically serve everyone, being exceptional for one precise segment is a stronger competitive position than being adequate for many. The up-market and geo expansion came later — only after the core was locked.

Run founder-led sales all the way to Series A, even in complex categories. John was the sole AE and solution consultant at Campfire for nearly two years — demoing the product himself in a category that traditionally separates AE and SE roles entirely. His reasoning: the feedback loop you control as the only seller is what lets you function as an effective PM when the team is lean. Once you hand that off, you lose the translation layer between customer pain and product decisions. His rule: no matter what AI sales tooling exists, get to Series A PMF metrics first.
