“Every small business should run itself” | Lassie with a16z

Summary

Alex Rampell and Olivia Moore interview Lassie cofounders Steijn Pelle and Frédéric Renken about using AI agents to automate small business administration, starting with dental practices. Lassie embeds in dental offices, automates billing, insurance claims, and patient payments, and reports 98% automation. The discussion covers the large healthcare administration market, distribution to SMBs, incumbent dynamics, and Alex's broader thesis that AI lets software perform labor and expand software markets.

• Lassie started by embedding in dental offices to learn administrative workflows first-hand.
• Its AI agents automate billing, insurance claims, patient payments, and other practice operations.
• There are about 160,000 US dental practices spending roughly $200,000 annually on admin labor.
• The company plans to expand from dentists to other healthcare verticals and eventually all small businesses.
• AI models still lack encoded real-world workflows, requiring context, tools, and product work.
• SMB distribution is difficult because owners are busy, non-technical, and often not on typical B2B databases.
• Alex Rampell argues AI software doing labor massively expands software TAM and that public markets may be mispricing software versus AI.
