From Kalo Yankulov, exited co-founder Encharge / founder Sensorhub
In 2019, I had $1,000 to my name and decided to compete against HubSpot (the company that invented inbound marketing), Mailchimp ($1B ARR), ActiveCampaign (1,000+ employees), and Salesforce (the granddaddy of SaaS itself). Companies whose marketing budgets had more zeros than my GTA bank account
We bootstrapped to $2M in revenue and sold that business for 7 figures.
Our only channel?
SEO.
This book shares how.

From $1K to Exit
Back in 2019, I was doing bare minimum freelance work to survive. My technical co-founder, Slav, had just exited Post Planner. We validated a few ideas until we made $3,950 in pre-launch revenue for a marketing automation tool, relying purely on product-founder fit and ignoring quasi-science validation frameworks (nothing wrong with these; it’s just that, at some point, you get tired and do whatever the F you want).
Five years and 40,000 monthly organic visitors later, here’s where we landed:
No paid ads. No cold email. No partnerships.
