Founder Fridays: Build for Yourself with Raphael Schaad, Founder of Cron and Owais Khan, PMM, Notion

A practical path to scaling a “broad” product category starts with building something sharply useful for one real person—then stacking outsized value on top of existing infrastructure. Raphael Schaad, founder of Cron (acquired by Notion), describes how a calendar market that seems impossible to tackle at scale became manageable by treating the early product as a toy: a small, personal fix that solved a specific annoyance. In his case, that meant collapsing the empty overnight hours in Google Calendar via a Chrome extension. The add-on quickly attracted thousands of users overnight, signaling that the problem wasn’t unique to him and that a focused wedge could grow into a much larger product.

That “build for yourself” approach is paired with a second principle: don’t try to build the whole category at once. Schaad argues that solo founders should apply pressure where value can be created with minimal engineering—adding “1%” features that capture a large share of the experience. For Cron, that meant standing on the shoulders of Google Calendar rather than rebuilding scheduling from scratch. He used Electron to wrap Google Calendar into a desktop environment, then focused on high-leverage workflow improvements during the Zoom era—extracting Zoom links and delivering timely notifications so meetings started on time instead of arriving late through email. The broader lesson: in big markets, the fastest route to traction is often finding the right point in the value stack to deliver a small but meaningful upgrade.

Cron’s early growth also hinged on go-to-market design, not just product quality. Schaad says the launch moment mattered less than what followed, and he pursued a deliberate channel strategy: invest ruthlessly in a small set of channels and become “an 11 out of 10” in them. At the time, that meant email and Twitter, with no LinkedIn and no paid marketing. Email wasn’t treated as generic lifecycle onboarding; it became a product update ritual built around beautiful, regular change logs. Those emails were written in the language users used in bug reports and feature requests, and they were structured to invite replies—no no-reply addresses—so feedback flowed back into the product. Twitter then acted as the amplification loop: change logs linked to tweets and videos, and users responded across both channels, creating a feedback-and-excitement cycle.

The same philosophy shows up in how Notion approaches “release marketing.” Schaad highlights the power of closing loops: when users request features, the founder tracks them and later sends personalized updates when those changes ship. Even at early stages, that kind of non-scalable attention can create “thousand true fans,” and tools (including AI and outbound platforms like Outreach) can help scale personalization without turning the brand generic.

Finally, the conversation connects Cron’s acquisition by Notion to a larger product strategy. Notion’s “Lego blocks for software” metaphor frames Cron as a missing piece around time and calendar, enabling Notion to expand into a connected workspace that now includes email and calendar. Looking ahead, Schaad’s advice for 2025 is to focus on distribution—the scarce resource when AI makes building cheaper—and to keep early execution grounded in fast iteration, thoughtful narrative, and design-level attention from day one.
