You burn ~75,000 net a month and have ~10 months of runway.

  • At this pace your cash lasts about 10 months before reaching zero.
  • Most investors expect you to start a raise with 9 to 12 months of runway left, so begin financing conversations now.
  • This is net burn, new revenue and one-off costs both shift it, so recompute at the close of each month.

Next stepTrack burn monthly and revisit the runway target before each hiring or spending decision.
