Co-Founder, Growth & Marketplace

8.0% – 12.0%We are building the operating system for Sweden's physical second-hand economy, and we need the commercial co-founder who makes the supply side run. Sweden's second-hand market is tripling. 62% of Swedes bought second-hand in 2024. EU regulation is accelerating commercial demand for circular economy data. The cultural shift has already happened. What has not been built is the infrastructure, and the commercial engine, that serves it. CircuCity connects two supply sources to a national buyer base for the first time. The first is the 2000+ physical second-hand stores across Sweden — charities, vintage boutiques, municipal recycling stores, that hold enormous inventories and almost no online presence. The second is the tens of millions of individual Swedes who want to sell but find existing platforms too slow and too fragmented to bother with.The product is live. The first store partners are signed. Individual sellers are onboarding. What we need now is the commercial co-founder who turns proof of concept into a running engine. WHAT YOU WILL OWN: You own the supply side — both of them. For stores: partner identification, relationship building, and closings that create the inventory density that makes the buyer experience better than any alternative. For individual sellers: acquisition, activation, and the community mechanics that turn occasional listers into regular ones. For buyers: demand activation, referral loops, and the flywheel that compounds both supply sources together. For the business: commercial strategy, pricing, partnerships, and the city-by-city GTM playbook that scales from Vasterbotten to Stockholm, Gothenburg, and the Nordics.And as a co-founder: investor conversations, commercial metric ownership, and a real equity stake in what this becomes. WHAT WE ARE LOOKING FOR: You have scaled a two-sided marketplace before, or something close enough that you understand the cold start problem and the supply-demand sequencing challenge. You know that the supply side is always harder. You know how to build it before the demand exists to justify it. You understand that store partners and individual sellers are different customers with different motivations and different success metrics, and you can build a strategy for both simultaneously without letting one crowd out the other. You have run or owned P&L, CAC, LTV, retention, cohort analysis — these are how you understand whether growth is real. You have managed commercial teams, run multi-channel growth, and built partner relationships at scale.Sweden-based is a firm requirement. The store relationships, community activation, and investor relationships that matter here require physical presence. WHAT WE OFFER This is an equity-only role at the pre-seed stage. No salary until the pre-seed round closes. Equity of 8–12% structured with a one-year cliff and four-year vest — the specific number reflects timing of join and contribution to the raise.A founding team that knows this market deeply. A live product with signed store partners and onboarding individual sellers. And a market that has never had a platform built specifically for it. TO APPLY: Send us your CV and supply us with two paragraphs response to the following questions.How did you solve the supply side when demand did not yet exist to justify it — and how did you manage two different types of sellers simultaneously?What makes you ready to work without a salary for the next 12 months?
