Show the line
Every screen should make it obvious whether the line is going up or down. If a chart doesn't answer that, it doesn't belong.
About
Abunder started in a single cell of a Google Sheet.
A running total of accounts, real-estate guesses, and a column for "stuff I'd forget about if I died." It grew to sixty rows, then a hundred, then a separate tab for the cars, then a pivot to show growth over time.
It was ugly. It was also the single most motivating financial thing any of us had ever done. The line went up, even in months that felt bad. That's the secret the existing apps bury under transaction feeds and budgets nobody keeps.
So we built the spreadsheet a proper home. Abunder is for people who want the compound to be obvious, not abstract. The product is opinionated because the spreadsheet was opinionated. We kept what mattered and deleted the rest.
Three principles guide every feature:
Every screen should make it obvious whether the line is going up or down. If a chart doesn't answer that, it doesn't belong.
You can export everything to CSV at any time. No lock-in. No dark patterns. We never sell or share your data — ever. Delete your account and it's gone that day.
No streaks, no nudges, no "you spent 4% more on coffee this week." Abunder is a mirror, not a megaphone.
Timeline
Three friends, one shared Google Sheet, one running joke about the "empire."
A weekend prototype of the net-worth chart. It was terrible. We couldn't stop opening it.
First 30 friends and family. First milestone crossings. First time someone emailed us crying about their first $100K.
Hardened the data model, shipped Plaid sync, the Sankey, and the milestone system. Households went into private preview.
Public launch this year. Free + Pro at the start, Family shortly after.
