Launch week: every idea card is free.Get Pro

SaaS ideas, mined from what people actually complain about.

Every idea comes from real Reddit posts, was researched against today's competitors, and survived an independent skeptic before it made the list.

Missing Repair Information

Field technicians across trades cannot quickly access accurate, equipment-specific diagnostic and repair information, causing slow fault tracing, misdiagnosis, and wasted site visits.

In their words

I have spent hours just trying to get the needed information for a 2021 GLS recently, which has a suspension fault of some sort, to no avail.

r/mechanics on Reddit

I would pay for this idea on older models where, as you say i can't find squat on it

r/hvacadvice on Reddit

I tried various ways. Hazards, scan tool, doors but it would send a signal for a split second and go flat.

r/Justrolledintotheshop on Reddit

service information is down so I can't get the new code

r/mechanics on Reddit

You drive hours to a distant site just to realize the problem is something incredibly simple, or because the user is completely clueless.

r/sysadmin on Reddit

Tell me why I can’t get a condenser fan motor for a TWO YEAR OLD Trane Precedence RTU?!?

r/HVAC on Reddit

he had run and common reversed on the contactor despite the 2" flags on each lead telling them where to land them and ruined the compressor

r/HVAC on Reddit

I need a proprietary handheld or a specific laptop software tool to even read the fault log properly.

r/Elevators on Reddit

if both show as just non-green, the tech ends up tracing wires on a sensor that's only inactive because the cycle hasn't gotten to it yet

r/PLC on Reddit

Still does it. No events present when it goes nuts like this.

r/forkliftmechanics on Reddit

none of those shiny trophies matter when the actual field techs can't install them without a tech support hotline on speed dial

r/sweatystartup on Reddit

the 4g SIM reader on these things is one of the worst I have seen. Constant calls saying "my laptop won't connect, it just says no SIM"

Why those fall short

  • signals only last a split second and go flat
  • codes and freeze frames are wiped before the shop can read them
  • Error codes lack explanation; vendor support slow or unavailable; manuals unhelpful.
  • manufacturers do not publish manuals online; phone resets manual and loses scroll position
  • service information down, boss cannot provide good manual
