Replaces Carta ($600+/mo) + Spreadsheets
Carta charges $600/mo and treats your sub-$25M fund like a rounding error. You've thought about tracking ownership in a spreadsheet instead — and honestly, for most emerging managers, that's exactly what happens. There's a middle ground.

Carta built a great cap table product. Then they priced it for institutional funds and deprioritized support for anyone managing less than $25M. After their 2024 data privacy scandal, emerging managers started looking for alternatives. But the only options were spreadsheets or enterprise tools. Until now.
