- From $30/day cost per user to viral growth.
- How a 'terrifying' decision paid off.
- Product-led strategy in healthcare tech.
In a counter-intuitive move that sent shivers down the spines of CFOs, Heidi, an AI product for healthcare, made its core offering entirely free. Faced with the challenge of reaching overworked doctors who avoid sales calls and cold outreach, and with no marketing budget, the company embraced a radical product-led growth strategy that transformed its business model overnight.
Heidi targeted a difficult market: doctors who are constantly pressed for time. With no funds for traditional advertising, conferences, or a sales team, the small team of 10-15 people needed a disruptive approach to get their new AI note-taking and transcribing product into the hands of users. The solution? Make it free.
This decision was met with understandable apprehension, particularly from the financial side, as the compute-heavy task cost approximately a dollar per note. With some doctors generating up to 30 notes a day, Heidi was effectively paying $30 daily per active user with no immediate revenue. However, the team viewed this expense not as a cost, but as their marketing budget, drawing inspiration from successful product-led companies like Canva and Notion. This meant a dramatic shift from traditional enterprise margins to a consumer app model, prioritizing distribution over direct sales.
The key to success lay in eliminating every possible piece of friction. Heidi ensured that signing up was incredibly easy, requiring no credit cards, sales calls, or IT approvals. The goal was to 'hack' users into experiencing the product's value immediately. This strategy paid off almost instantly. Clinicians, desperate for tools to save them an hour or two a day, quickly adopted Heidi. The immense value created a powerful viral loop, as doctors eagerly shared their discovery with colleagues and even patients, some of whom were also clinicians.
After just seven sessions with the free version of Heidi, doctors exhibited a remarkable 90% weekly retention rate, making the product an indispensable part of their daily workflow. Once trust was established and the initial 'blush' of excitement wore off, users began to desire customization and integration with their existing medical records. This is where Heidi's commercial model kicked in, offering paid features for personalization and team collaboration. By making the product free, removing friction, and allowing users to experience profound value, Heidi effectively turned its product into its most potent lead generation and sales engine.
“making it free in the end actually was the best way for us to generate leads for sales.”
