Product Overview

Lassie is an AI healthcare admin worker that automates back-office operations for independent dental and medical practices. The platform handles insurance enrollments, EFT payment posting, claims reconciliation, appeals, and follow-up work.

It integrates directly with practice management systems and operates as an autonomous agent rather than a copilot, saving practices 30-100+ hours of administrative work per month while catching underpayments and denials that used to slip through.

Market Outlook

Dental practices spend roughly $200,000 per year on administrative staff and lose 100+ hours monthly to manual back-office work. Existing software tools do not solve the core compliance and workflow problems.

Lassie targets the $100-200K admin OPEX per practice with AI agents that replace manual labor rather than augment it. The initial wedge is dental, but the broader opportunity extends to all small business back-office automation, representing a massive TAM as AI agents shift the unit of value from software to labor.

Competitive Advantages

Founder-led product obsession: Steijn Pelle and Frédéric Renken embedded themselves in a dental practice for months before writing code, manually processing payments to understand workflows from the inside.

Deep PMS integrations and purpose-built AI for EOB parsing enable cent-level accurate posting. Strong word-of-mouth growth with 700+ practices across 49 states and minimal sales team. Five-figure ACVs with clear expansion path to capture full $100-200K admin OPEX per practice.

Competitive Disadvantages

Limited to dental practices as the initial wedge, though expansion to broader medical and small business verticals is planned. Narrow initial TAM compared to horizontal AI automation platforms.

High touch onboarding requires significant founder and engineering involvement for new practice integrations, which may limit scaling velocity compared to fully self-serve SaaS products.

Pricing Strategy

Five-figure annual contract values (ACVs) with pricing tied to the value generated from automating insurance AR and back-office workflows. The wedge product alone commands a five-figure annual contract, with a clear expansion path to capture the entire $100-200K in administrative OPEX that practices currently spend.

Pricing is positioned to deliver more value than cost, targeting the full-time staff equivalent spend that practices currently allocate to manual admin work.
