Before writing a line of automating code, Lassie's founders sat in dental offices doing the billing work by hand. They automated away their own jobs — and that ground-level experience is why their product works at 98% accuracy when other AI tools fall short.

Steijn Pelle brings the abstract thesis down to numbers. There are approximately 160,000 dental practices in the United States. Each spends around $200,000 annually on administrative labor [1] — Steijn Pelle "160,000 dental practices in the US: There are approximately 160,000 dental practices in the US, each spending roughly $200,000 a year on ad…" 24:12 . Much of that labor is either impossible to hire or performed by the doctor themselves after hours — Dr. Kwon at midnight, Dr. Sloop until he quit. Multiplied out, that is over $1 billion in recurring revenue for just the dental segment, before expanding to physical therapy, primary care, or any other healthcare vertical. Lassie's pricing reflects the value equation directly: the company already charges five figures for its first agent, which currently automates roughly 30 hours of the available 200 monthly labor hours. The framing Pelle uses is telling: customers don't see Lassie as software they subscribe to. They see it as someone who comes in and runs the practice for them. That shift in perception — from SaaS product to autonomous operator — is what commands five-figure contracts from small businesses that would balk at that price for traditional software.
There are approximately 160,000 dental practices in the US, each spending roughly $200,000 a year on administrative labor costs.
Each dental practice spends approximately $200,000 per year on administrative labor that Lassie's AI agents can replace.
Lassie charges five figures for its first agent, which currently automates 30 hours of labor per month, out of 200 total hours available.
The majority of Lassie's customer growth comes from dentists recommending the product to other dentists in study clubs and professional networks.
Lassie has reached 98% automation on its core billing and insurance claims workflows for dental practices.
SiteGPT attracted over 1 million visitors and $500K in total revenue without spending a cent on paid marketing. The secret: engineering as marketing — building free tools that rank on Google.
Bhanu quit his first job after just 8 months, moved back to his parents' house to cut costs, and started building. One product sold for $250K; the next hit $10K MRR in its first month.
90% of SiteGPT's Google search traffic comes not from the main product but from ~50 free tools Bhanu built. Each tool targets a low-competition keyword and funnels users back to the paid product.
50,000 monthly visitors become 200 leads, 60 trials, and roughly 15–24 new customers per month at ~$100 average revenue each. Add a $1,700–$1,800 LTV and you have a very healthy SaaS.
Start with a blank Ahrefs search, layer in keyword filters (include term, KD < 10, volume > 1,000), list candidates in Notion, design a CTA linking to your main product, then score by volume, difficulty, build effort, and product relevance. That's the whole playbook.
Marketing feels painful for most builders. Engineering as marketing flips the script: instead of writing cold emails or blog posts, you build things — and those things rank on Google forever.
Don't spend months perfecting before launch. Ship the core feature, get real users, and let their feedback dictate the product roadmap. Premature polish is a trap.
SiteGPT launched and hit $10,000 MRR within its first month. That momentum was so overwhelming that Bhanu sold his existing SaaS, Feather, for $250,000 to free up all his time.
PropGPT launched with 20 downloads a day and strong influencer marketing but hit a ceiling at $1,000–$2,000 MRR. High download numbers masked a critical flaw: almost nobody stuck around after the free trial ended.
