How I Built It: $37K/Month Notion App | Starter Story

AI Summary

5 min read

Julian built a form builder for Notion users called NodeForms. He coded the first version in six days. The product now has close to 100,000 registered users and generates roughly $37,000 in monthly recurring revenue. He did this while keeping his full-time software engineering job, working on the project during a three-hour daily commute. The conversation covers how he found the idea, validated it, marketed it, and built a sustainable solo business.

Building on a Platform, Not From Scratch

Julian deliberately built NodeForms on top of an existing platform—Notion. He had been a Notion user for years and jumped on the opportunity when Notion released its API. His reasoning was straightforward: building around a platform is easier than building a standalone SaaS because you don't have to create a community from nothing. You can "cannibalize" part of the existing user base and solve a specific sub-issue. Notion already had a huge, engaged community on Reddit and Facebook groups, which gave him a ready-made audience to market to. He acknowledges this approach has its own risks—dependency on the platform—but for a solo founder starting out, it dramatically reduces the hardest part of a new business: finding your first users.
