We built software because our physical factory was bleeding money to Excel.

For years, we ran a luxury custom rug manufacturing business. It is a massive global industry, but behind the scenes, it runs entirely on fragmented WhatsApp messages, messy Excel sheets, and manual calculators.

Every time a client asked for an abstract shape or a multi-currency quote, we lost hours to complex surface-area math. A single miscalculation meant bleeding profit margins. We tried generic CRMs, but they couldn't handle the physics of textile production (like yarn dyeing stages or loom assignments).

Out of pure frustration, we partnered with developers to build our own internal quoting engine and factory pipeline. It worked so well that we turned it into a B2B SaaS (Rug Estimator PRO) to help other manufacturers and interior designers stop the margin leakage.

It made me realize that the biggest SaaS opportunities aren't always trendy AI apps—they are in digitizing "unsexy," traditional physical industries that are still stuck in 2005.

I’m curious to hear from other makers:

• Are you building for a highly specific or "boring" physical industry?

• Do you think niche vertical SaaS is a safer bet right now than building broad horizontal tools?

• What was the "broken workflow" that forced you to build your current product?

Would love to hear your stories!
