[Technical] Built a SaaS that lets you hit REST APIs via SMS

[Technical] Built a SaaS that lets you hit REST APIs via SMS — looking for cofounder

The idea came from camping with no cell signal but SMS still worked. Built a platform where you define commands that invoke REST APIs over text message. Think: text "STATUS" to check your server, text "DEPLOY staging" to trigger a pipeline.

MVP is ~90% done. React frontend, Node backend, PostgreSQL. Integrated with Twilio for SMS handling.

Use cases I see: IoT monitoring, devops on the go, field workers with bad connectivity, emergency systems.

Looking for someone US-based who finds this interesting and wants to help figure out distribution + pricing. Technical or non-technical — I just need someone who'll obsess over this with me.

Satellite internet companies (Starlink competitors) were looking at exactly this kind of SMS-as-fallback architecture last year. Might be a B2B angle worth exploring — bundle your platform as the "offline mode" for existing SaaS products.

Cool idea. Heads up on costs: Twilio gets expensive fast at scale. Look into SignalWire — same API surface, fraction of the cost. Made a huge difference when I built a texting-based controller for a client project. Also curious how you handle the 160-char SMS limit for API responses? Do you paginate? Truncate? Send multiple messages?

The UX challenge here is fascinating — you're essentially designing a CLI that runs over SMS. Have you thought about onboarding? Most people's first reaction will be "why not just use the app" so you need to nail the "no signal" story in the first 10 seconds. I'd be happy to do a UX review of your MVP if you want an outside eye. DM me.

I bootstrapped two developer tools to $20k MRR and this reminds me of my first one — very niche, very sticky once someone integrates. The key is finding 10 users who absolutely need this, not 1000 who think it's "cool." Who are your first 3 paying customers going to be? If you can answer that specifically, you don't need a cofounder — you need to start selling. If you can't, that's the real problem to solve.
