In this episode of Lenny's Podcast, featuring Karri Saarinen and Lenny Rachitsky, Inside Linear: Building with taste, craft, and focus | Karri Saarinen (co-founder, designer, CEO) explores inside Linear: Opinionated Product Craft, Lean Teams, And Relentless Focus Karri Saarinen, co‑founder and CEO of Linear, explains how Linear builds a highly polished, beloved issue-tracking product using a tiny, very senior team and a culture obsessed with craft, speed, and focus. Rather than A/B tests and feature-level metrics, they rely on deep customer understanding, taste, and opinionated product decisions, plus a strong emphasis on retention and trust over short-term wins. Linear minimizes specialization (one PM for ~50 people, rotating project leads) and uses structured cycles, opinionated workflows, and high design quality as core differentiators in a crowded market. Saarinen also details Linear’s selective growth approach—from waitlisted private beta and segment-by-segment product‑market fit, to a unique paid work trial hiring process and culture rituals that reinforce quality and authenticity.

My belief is that, like, any domain or industry, the more it matters, the more the design matters. What happens is, like, whenever there's, like, a new paradigm, I don't know, it's like the mobile or the web or something, the first iterations of those products existing there, they don't have to be like super well-designed necessarily because they are the first. But then like as, as you build the 100, like, thousand, like, different email clients, any email client now has to be like pretty good to be, be even considered like reasona- like an email client. It's like that the bar is so high. So I think like today it's almost like a very basic thing now, pretty much from the very beginning you need like pretty high level design for people to even like pay attention or consider you seriously.
(instrumental music) Today my guest is Karri Saarinen. Karri was the founding designer at Coinbase, principal designer at Airbnb, co-founder of two previous startups, and most recently is the co-founder and CEO of Linear, which I am fairly confident is the fastest growing and most beloved issue tracking tool in the world, and something that a growing number of product teams are using to build their own products. Karri and his team are building their company and their product in a really unique way with a huge focus on craft and quality, no A-B tests, no metrics-based goals, instead a focus on taste and opinions. Also, no durable cross-functional teams. Instead, teams assemble around a project and then disperse once it's done. Also, they have just one product manager as the head of product, and that's it. In our conversation, Karri shares how he built a culture around quality and craft, how he makes trade-offs, and how he operationalizes quality and thoughtfulness, where design can be a differentiator in competing against incumbents. We talk about something called the Linear method of building product, which is big on building opinionated software, working in consistent cycles amongst other principals. We also get into Linear's unique hiring approach, which involves a paid work trial where candidates work alongside a team for a number of days instead of just having an interview. Also, a glimpse into how Linear got their first 10 customers, found product market fit, and scaled their growth engine. There is so much gold in this episode. I am very excited for you to hear it. With that, I bring you Karri Saarinen after a short word from our sponsors. This episode is brought to you by Mercury, who I also happen to use for my business checking account.
