A longer bio is on its way. In the meantime, the easiest shorthand is the list of companies below — early-stage software bets in places where physical and financial reality still bites: construction, energy, real estate, industrial infrastructure.

The proper bio — what I work on day-to-day, how I got here, what kinds of companies I write checks for — is being written. For now, the portfolio above is the most honest summary.
