How did your SaaS journey begin?

Leah:
I’ve always loved spreadsheets but hated how hard it was to use AI tools like ChatGPT with them. I kept copying content from Google Sheets to ChatGPT and back - it was clunky and slow.

I mocked up an idea: a spreadsheet function that lets you run AI prompts like formulas. I called it PromptLoop and initially just had a landing page explaining the idea. I shared it on Reddit and Indie Hackers to see if anyone else struggled with this too.

The feedback was immediate - lots of upvotes and comments like “I need this yesterday.”

What made you decide to build it into a full product?

Leah:
The validation came from people literally asking for a way to pay. I didn’t even have a product yet - just a demo video using Glide and Zapier. But I got 50+ signups in the first week and a few folks emailing me asking when they could subscribe.

That’s when I knew I had to build a working prototype fast. I used no-code tools like Glide and Make to stitch it together. It was rough, but it worked - and people used it.

What’s the product and who is it for?

Leah:
PromptLoop is like ChatGPT for spreadsheets. You can write prompts directly into your spreadsheet cells, and it fills in results automatically.

It’s designed for marketers, SEO writers, e-commerce teams, and virtual assistants who want to automate repetitive content tasks without leaving Google Sheets or Excel.

How did you grow your user base?

Leah:
I went where my users hang out: Reddit, Indie Hackers, and X/Twitter. I posted honest build logs, failures, and feature demos. I also created free templates (like “Generate product descriptions with AI”) and shared them in Google Sheets communities.

SEO came later - I started targeting search terms like “GPT Excel function” and “AI Google Sheets plugin.” I also added a free plan to get more users in the door.

Now, I get about 40% of my traffic from organic search, 30% from Twitter, and 30% from referrals.

What are your revenue numbers and pricing structure?

Leah:
I’m making around $6,500/month now, with about 220 paying users. Here’s the pricing:

Free: 25 AI tasks/month

Pro: $19/month (2,000 tasks)

Business: $49/month (10,000 tasks + team sharing)

Most users land on the Pro plan. I offer a 7-day free trial, no credit card needed.

What tools are essential for running your solo SaaS?

Leah:
I’m a non-technical founder, so I leaned heavily on no-code:

• Glide - For the initial MVP

• Make (Integromat) - To connect Sheets, OpenAI, and Stripe

• Stripe - Payment processing

• Outseta - User management and CRM

• Framer - Website

• Notion - Product roadmap and support docs

No engineers, no full-stack app - just tools that help me ship fast.

What’s your biggest win so far?

Leah:
Hitting 1,000 users was huge - but the best moment was when a marketing team emailed to say PromptLoop cut their blog production time in half. That kind of outcome is the goal.

What was your biggest mistake?

Leah:
I waited too long to charge. I was nervous people wouldn’t pay, so I kept everything free for too long. Once I added a paywall and a usage limit, not only did revenue start, but retention improved - people value what they pay for.

What advice would you give to first-time founders?

Leah:
Don’t overthink the tech. If you’re not a developer, use no-code. The real moat is distribution and customer insight.

Build something small, useful, and fast - and talk about it publicly. Users don’t want polished. They want useful, transparent, and responsive.
