A tradesperson-founder, four trades, one bench.
SecondShift is the diagnostics agency one owner built because callbacks don’t ship themselves. Four trades, one diagnostic shape, and a bench of specialists on the line for anything the AI is uncertain about.
Founder
Started in a service van in ’98. Still reads the dispatch tickets.
Started in a service van in ’98, ran calls for fifteen years, watched good techs ship callbacks because the diagnostic step was a phone call and a guess.
Built SecondShift with that constraint in mind: a dispatch copilot that ranks probable causes the same way a senior tech talks through the ticket — and a bench of specialists on the other end of the line for anything the AI is uncertain about.

The bench
The bench is the part most AI “dispatch copilots” don’t have.
- WHAT IT IS
Specialists behind every ranked cause.
A bench of diagnostic specialists who read the ticket when the AI flags low confidence — or whenever a callback is on the line.
- WHEN IT RUNS
Escalates when the AI is uncertain.
Configurable escalation threshold per shop. Default kicks in when any ranked cause sits under 65%, on warranty tickets, and on every callback.
- WHAT YOU GET
A signed second opinion, inline.
A specialist reviews the dispatch tape, calls the tech back if needed, and writes a signed second opinion that lands inline with the AI output.
- WHY IT MATTERS
The difference between a guess and a verdict.
Owners sleep through the night. The bench is the difference between a ranked guess and a verifiable verdict on a $4,000 refrigerant job.
