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.

Hand Calculations and Layouts

Engineers and tradespeople waste time on manual, error-prone calculations and spatial layouts that software handles poorly or not at all.

In their words

two of the companies just split their original load into two units and send back the quote (ie 60k into 2 30k units)

r/HECRAS on Reddit

my family envelopes come out as huge overlapping blobs that cover half the chart and tell you nothing

r/AppDevelopers on Reddit

Are you able to provide engineering for unusual designs and roundwood? Not necessarily stamping, but working out what is viable for structures that don't follow common forms?

r/timberframe on Reddit

My clients would be happy to pay a bit of a premium to have an uninterrupted concrete wall to scrape up against on the interior

r/StructuralEngineering on Reddit

They unfortunately flipped the house layout 180 degrees. My windows are where my garage will be and my pockets for my beams are in the wrong spot.

r/Homebuilding on Reddit

Every single window was 1” too big for the openings we had painstakingly prepared

r/Carpentry on Reddit

i asked the fabricator for more detailed info about the panel construction and they sent me a brochure. a brochure.

Where they talk

  • r/StructuralEngineering
  • r/MEPEngineering
  • r/HECRAS
  • r/fea
  • r/civilengineering
  • r/civil3d
  • r/HVAC
  • r/electricians

Tools they use today

  • HEC-RAS
  • Excel
  • Revit
  • Ansys
  • Civil 3D
  • AutoCAD
  • Photoshop
  • Python

Why those fall short

  • joist design is a black box; no analysis provisions exist
  • Fabricators send brochures and spec sheets with no actual load data
  • hallucinated load conversions and lacked influence line knowledge
  • Shear flow math invalid once section cracks; no tool handles composite action
  • Manufacturers change deflection numbers without revising steel
