Stay loco.
Support localhost.
We're a one-engineer shop out of Loudoun County building software for the problems nobody else bothered to solve. Finance, scheduling, coaching. If it helps real families get organized and stop guessing, we're building it.

A little loco.
A lot of localhost.
We build for people who have better things to do than fight with spreadsheets. Every feature earns its place or gets cut. Ship fast, stay scrappy, keep it local.
No complexity theater
If a feature makes you feel like you're doing "work" to use it, we failed. Interfaces should disappear and let you think about your actual life.
Your data stays yours
Bank credentials never touch our servers. OAuth tokens are encrypted in Firestore with server-side-only access. We can't see your balances even if we wanted to.
Find the gaps, stay loco on them
We don't rebuild what Mint or YNAB already do. We find the blind spots other tools ignored: vehicle fleet costs, replacement timing, household tax strategy, and projections from next week to next decade.
