founder-ledger-trackerv1.0.0

A bootstrapped solo founder sets a goal of reaching $1,000 in monthly recurring revenue by a target date and uses the tracker to get a one-line daily nudge on progress and deadline proximity. The branchable exit codes let their shell script trigger different follow-up actions, like logging progress or sending themselves an alert when only three days remain.

A freelance designer tracks a daily discretionary spend cap alongside a quarterly income goal, invoking check each morning from a cron-like script. Exit code 1 at 80% of the cap reminds them to slow down, and exit code 2 blocks further non-essential purchases until the next day. The plain JSON state file keeps all data local and private.

An indie developer sets a deadline for their Steam launch and uses the tracker's soft trigger to surface a reminder when the deadline is within three days. Automated build scripts call reminder-text to embed the current countdown in their daily standup notes without mutating state.

A two-person marketing agency uses the tracker to monitor a quarterly new-client goal and a daily ad-spend cap, checking status at the start of each workday. The hard trigger exit code 2 prompts an automated Slack ping so the team can pause campaigns before overspending. State stays in a JSON file the agency fully controls.

An AI researcher running autonomous agent experiments wires the tracker into an agent loop so the agent checks its own milestone progress and spend budget before each decision cycle. The deterministic exit codes give the agent a clean signal for branching behavior, and the stdlib-only design avoids dependency conflicts in sandboxed environments.

Offer the tracker as a free MIT-0 Python file while selling an optional hosted companion that syncs state across devices and sends scheduled reminders. The hosted tier adds convenience without changing the offline-first core, appealing to users who want cross-device continuity.

Package the tracker together with pre-built shell scripts, cron configurations, and dashboard templates for common founder workflows. The core tool stays free, while advanced automation packs and integrations are sold as one-time purchases.

Use the tool as a lightweight entry point for advisory engagements where you help founders set realistic milestones, budgets, and automated check-in workflows. Revenue comes from setup, customization, and ongoing coaching rather than the software itself.
