TrialConvert Diary

The Problem

SaaS founders on r/indiehackers consistently report that their free trial conversion rates are abysmal but they have no visibility into what trial users actually did — or didn't do — before churning silently. TrialConvert Diary instruments your trial period with a lightweight event tracker and generates a per-user 'activity diary' showing the exact feature sequence (or absence) that preceded conversion or abandonment, so founders can pinpoint the one activation moment that predicts paying.

Target Audience

Early-stage SaaS founders with 50–500 monthly trial signups who lack the budget for Mixpanel or Amplitude but need activation insight

Monetization Angle

Freemium up to 100 trial users/mo; $29/mo for up to 1,000 trial users tracked

Evidence & Source Signal

Multiple Sources: Privacy-first analytics tools have removed third-party tracking, leaving a gap where founders have less behavioral data than ever precisely when trial-to-paid conversion is their most important metric.

Why Now

Privacy-first analytics tools have removed third-party tracking, leaving a gap where founders have less behavioral data than ever precisely when trial-to-paid conversion is their most important metric.

MVP Scope

A single JS snippet that captures page/feature visit sequences during trials and a dashboard showing a ranked list of 'paths that converted' vs 'paths that churned' with percentage breakdowns.

AI Angle

LLM summarizes each cohort's behavioral pattern into a plain-English hypothesis ('Users who hit the export feature within 48 hours convert at 3x the rate') so non-analyst founders can act without SQL.

Primary Risk

Founders must install a JS snippet, which creates an integration friction barrier — if the setup takes more than 10 minutes, they abandon it.

Validation Checklist

  • Survey 20 founders in IH Slack about their current trial conversion visibility and what they'd pay to fix it
  • Build a manual version using PostHog exports and deliver 5 'trial diaries' by hand to validate the format resonates
  • Post the concept on r/SaaS and r/indiehackers asking if anyone would swap their current analytics tool for this
  • Measure whether founders who see the demo ask 'how do I install this' within 2 minutes — that's the signal

Who Would Pay For This

Likely buyers are founders, operators, and small teams with a recurring business process. Start with Early-stage SaaS founders with 50–500 monthly trial signups who lack the budget for Mixpanel or Amplitude but need activation insight and validate whether this can replace a spreadsheet, manual review, or consultant workflow.

First 10 Users

Find the first 10 users by searching for recent complaints around "SaaS analytics" in Multiple Sources, developer communities, GitHub issues, and niche Slack or Discord groups. Offer a concierge version first: manually solve the workflow for a few users, then automate only the repeated steps.
