Build sharp tools
for sharp people.
GizmoBuild is a one-person software company building niche SaaS for collectors, coaches, and small operators. Niche markets where the existing tools are bad. Small enough for one person to build, focused enough to charge a fair price.

Who's building this
Founded by Brennan Snow— a Digital Product Manager with 18 years in medical simulation. The pattern: identify a niche where people are stuck on spreadsheets, build a tool that fits the hobby's vocabulary, charge a fair price.
Stay in the loop.
New product launches, occasional behind-the-scenes notes. Low volume.
