How We Work at ReplyRadar: Building in Public

Building software is messy. You have a vision, you write the code, and then real users touch it and everything breaks. At ReplyRadar, we decided from day one that we weren't going to hide behind a corporate veil. We are a small team, and we are building in public.

The Iteration Cycle

When we first launched our core email follow up tool, the idea was simple: CC us, and we remind you if they don't reply. But within a week, our users said: "Reminding me isn't enough. Draft the email for me."

So we pivoted. We integrated large language models to read the context of the thread and generate natural-sounding drafts. It took a while to get the prompt engineering right—early versions sounded like medieval squires—but eventually, we nailed the natural, professional tone.

Listening over Guessing

Our roadmap isn't dictated by what we think is cool; it's dictated by what our users are actually struggling with. We use Twitter, Reddit, and direct user interviews to figure out what to build next.

For example, the customizable multi-stage intervals (2 days, 4 days, 7 days) was entirely a user request from a real estate agent who needed different aggression levels for different clients. We built it, shipped it, and it became one of our core features.

We believe that the best products are built close to the metal with direct lines of communication to the people using them every day. ReplyRadar is built by humans, for humans.
