How One Developer Turned a Simple API into a $50K/Month SaaS
From 11 failed startups to a $50K/month success: How Jon built Bannerbear by solving his own problem and growing through transparency, not ads.(~1min 45 secs read)
THE BACKSTORY:
Jon is an experienced entrepreneur and developer with years of hands-on experience creating and launching software products.
In 2019, he committed to a challenge: build 12 startups in 12 months.
Most flopped. But during this process, he hit a recurring pain point:
Marketers and businesses were wasting time creating the same branded visuals over and over again for blog banners, product images, social posts, you name it.
So he built a tool to automate it.
It started as a basic image-generation API.
He used it himself. Then shared it online.
People loved it.
That project became Bannerbear.
THE PRODUCT BREAKDOWN:
Bannerbear is an API and UI-based tool that auto-generates images and videos from templates and data.
You create a template in the editor.
Then send in data via:
→ Zapier
→ Airtable
→ Google Sheets
→ Webhooks
→ Notion, Forms, CMS tools, etc.
It generates visuals like:
Social media graphics, Dynamic product images, Open Graph images, Video snippets
And it works at scale — hundreds or thousands of assets, all on-brand, in minutes.
Teams use it to save time, stay consistent, and fully automate content design.
THE GROWTH PLAYBOOK:
No ads. No cold emails. No sales team.
He built in public
He shared MRR(Monthly Recurring Revenue) monthly
He blogged his learnings and journey
Ranked on SEO and indie hacker circles
Here’s the truth:
People buy the product when they believe in the builder.
THE OUTCOME:
Today? $50K+/monthly revenue.
Thousands of customers.
Big brands. Solo founders. Agencies.
And Jon still owns 100% of it.
