Practice by Numbers: bootstrapped dental analytics hits $16.5M revenue target with zero VC
Founded 2015 as a side project by a Philips engineer and his dentist wife, Practice by Numbers grew to ~$12.5M revenue in 2025 with no outside funding.
Practice by Numbers
What the business is
Practice by Numbers is an all-in-one dental practice SaaS platform that sits on top of systems such as Dentrix and Open Dental, providing analytics, patient communications, marketing, payments and workflow automation to dental offices, priced per location.
Starting capital：No outside funding: Rohit Garg built the first version nights and weekends while employed at Philips Healthcare, and the company has been self-funded and profitable since its 2021 relaunch.
How it started
After helping his wife Aditi, a dentist, make sense of her practice data, Rohit Garg concluded that dentistry was massively underserved by software and started Practice by Numbers in 2015 while holding a full-time medical imaging role at Philips Healthcare. The first customer was his wife's practice, and growth came from dentists telling other dentists.
What happened
The company reached about $1M in revenue by 2018, then COVID 'cut the company at its knees' and forced a 2021 relaunch at about $2M. From there revenue roughly doubled repeatedly: about $4M in 2023, $8M in 2024 and $12.5M in 2025, with EBITDA of roughly 22-24% and about $1.5M in free cash flow. Growth stayed fully inbound - word of mouth plus trade shows and G2 - with no outbound sales team and no paid acquisition, while the product expanded into AI receptionist work and a payments product processing about $190M in GMV.
How it ended up
As of 2026 the founders expected to close the year at about $16.5M in ARR, roughly 35% growth, while targeting 30% EBITDA and $100M+ in revenue within ten years. Rohit Garg described the company as 'bootstrapped completely... not a single dollar that's been taken.'
Background
Practice by Numbers began in 2015 as a side project: Rohit Garg, a medical imaging professional at Philips Healthcare, spent weekends running spreadsheets and SQL queries against his wife Aditi's dental practice database to answer basic business questions. He concluded dentistry was underserved by software and built an analytics platform for it, with his wife's practice as the first customer.
The bet was that dentists would pay for software that mines their practice-management systems for insight - and that measurable results would spread by word of mouth. The company sat on top of systems such as Dentrix and Open Dental and expanded from analytics into patient communications, marketing, phones, payments and workflow automation, priced per location.
Revenue reached about $1M by 2018, COVID forced a 2021 relaunch at about $2M, and then growth accelerated: roughly $4M in 2023, $8M in 2024 and $12.5M in 2025 at 22-24% EBITDA and about $1.5M in free cash flow. All sales stayed inbound; there was no outbound team and no paid acquisition budget.
By 2026 Practice by Numbers served roughly 1,300 customers across about 2,000 locations with around 80 employees, was processing about $190M in annual payments GMV, and expected to close the year near $16.5M in ARR. Customers using the platform reportedly generate about twice the national average in dental production revenue, which is the flywheel the founders bet on.
What has to be true
- The founders chose profitability over scale: no outside capital meant no pressure to buy growth, and the company deliberately avoided paid acquisition that would have made unit economics worse.
- Dentists talk to dentists, so serving a few practices exceptionally well created a referral engine that outran any sales team the company could have afforded.
- A vertical entry point - analytics layered on existing practice-management systems - avoided replacing the systems dentists already trust.
- COVID nearly killed the company in 2020, and the 2021 relaunch forced it to rebuild lean, which kept later growth efficient.
- Expanding from analytics into payments and AI opened bigger revenue pools, including roughly $2B of addressable GMV inside the existing customer base.
What can be applied
In a fragmented vertical, a product that measurably improves customers' core numbers can replace a sales team: 2x national-average revenue per practice is the referral engine.
Aftermath
As of September 2026 Practice by Numbers remains a fully bootstrapped dental SaaS expected to close the year at about $16.5M ARR, with the founders targeting 30% EBITDA and $100M+ in revenue within ten years. The company employs about 80 people across the US and India, processes about $190M in annual payments GMV through Stripe and Adyen, and is building agentic AI workflows and an AI receptionist on top of its recorded and transcribed call data.
