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.

Outdated CAD and Design Tools

Users across many fields struggle with CAD and design tools that are slow, buggy, expensive, platform-limited, or poorly matched to their real workflows.

In their words

it's buggy, it's laggy, it's incredibly resource hungry, the error messages are frequently entirely unhelpful, and it's still possible to irreversibly break your model losing dozens if not hundreds of hours of work

r/SolidWorks on Reddit

After driving two hours for a site survey, it is now my favorite piece of tech my company invested in.

r/MechanicalEngineering on Reddit

The key in my opinion is to build something really niche in an area where there is an incumbent still offering windows software that looks like it came straight from '99.

r/vibecoding on Reddit

I’m hoping to avoid another expensive material-selection mistake

r/InjectionMolding on Reddit

I’ve had them for several years. I don’t have a problem. I’m just looking for something That’s a little bit more polished.

r/msp on Reddit

We have always designed these by hand but I feel the need to purchase a software to be able to design these quickly, efficiently and accurately.

r/Geotech on Reddit

I have not found any systematic, simulation based DFMA processes

r/MechanicalEngineering on Reddit

Stain matches are the biggest waste of time for any busy store past 3 million dollars.

r/sherwinwilliams on Reddit

I like being in control of the processing and verifying everything. Not going to put my license on the line for someone else's work.

r/Surveying on Reddit

I can't buy Coreldraw right now. But I need to make layered art.

r/lasercutting on Reddit

I need my toolpath to still do a helix around the part, but now, I need to keep the tool (facemill) flat on the flat faces, and only curve around the fillets.

r/CNC on Reddit

it’s quite expensive and requires a relatively powerful computer, even though we are only drawing in 2d.

r/CommercialAV on Reddit

I do not like to use cad software. It is painful to express ideas with it.

Why those fall short

  • buggy, laggy, resource hungry, unhelpful errors, models can break irreversibly
  • bloated piece of shit, worse than Microsoft Paint
  • extremely outdated and glitchy software
  • alternatives are getting eliminated or becoming crazy expensive
  • FreeCAD not enough; no app handles large files or DWG/DXF properly
