When we thought about who we wanted as a long-term partner, @arampell and a16z were our first call. Excited to build with a firm so aligned with our vision.
Jun 3
We’re thrilled to lead Lassie’s Series A. Most small businesses are run by reluctant operators. Owners set out to serve their customers and communities but end up buried in back-office work. Dental practices are a perfect example. Dentists train to care for patients, but much of their time is consumed by insurance claims, payment reconciliation, staffing, and cash flow. Lassie is building AI that runs small businesses, starting with dental practices. Before writing a line of code, Cofounders Steijn Pelle and Frédéric Renken spent months working inside a dental office, processing payments by hand to deeply understand the workflow. Lassie is not a copilot that creates more work for the practice to review. It does the work. We’re excited to partner with @steijnpelle, @fredericrenken, and the @lassieai team as they build toward the small business that runs itself. By @arampell and @omooretweets

Love seeing people build better software for reluctant operators of small businesses. The baker who ends up running a bakery. The hair stylist who ends up with their own salon. And here, the doctors and dentists who end up with their own practice. More attention on these small businesses, please. We've been building for them for two decades, and I can tell you they're starved for great, straightforward software. I'd bet on these guys. They've got the dirt of real work in the field under their fingernails. There's no better way to know than to do.
Today, we're introducing Lassie and $47M in funding led by a16z. We're building AI that runs small businesses, starting with doctors' offices. Lassie is already trusted by 700 practices across the country, working autonomously to provide them with 30 hours of labor per month. To get here, we first had to leave Robinhood and Superhuman to work in offices ourselves. Here's how that went.

Grateful to Alex for telling the story behind Lassie!
EXCLUSIVE: Lassie's AI agent helps dentists save hours of busywork. Now it's raised $35M from a16z. It started when CEO @steijnpelle heard his own dentist complain about a sea of paperwork -- then embedded in his practice to learn first-hand. My @UpstartsMediaCo exclusive 👀

I'd love a way to snooze tabs in @arcinternet I often keep tabs around because I need them later, but they add clutter until I can act on them and not always worth moving from tab to actual task

1/ Feels like just yesterday I was posting here about kicking off a search to find employees #4 and #5 for Lassie. Well, time flies when you’re having fun. Welcome aboard, @yousefa01 and Jeffrey Tang! Lassie has grown from a team of 3 → 5 and momentum is building! 🔥

jack-of-all-trades! we're looking for the first business hire to help doctors across the country run their practice someone who loves navigating complex systems as much as building relationships — and is hungry to own problems from 0 to 1 DM if that sounds like you!
Come work with me to put doctors — running their own SMB practice — in control of their finances. We’re recruiting teammate #6, the founding business hire, next. If that sounds enticing, DM me!

Another great example of the 2020s being the decade of healthtech! @fredericrenken and @steijnpelle are building products for a space dominated by shifty agencies and banks--a true pain killer for a massive TAM. Huge opportunity 👇

Do you agree that doctors learn medicine— not business— and shouldn’t have to be experts at both? Does building financial software to help doctors run their own, small practice sound like music to your ears? We’re hiring engineers #2 and #3 next: notion.so/lassie/Founding-So…
