A rolling plan that lists what the product team intends to ship and in what order, communicated as a statement of priorities rather than a delivery commitment.
Linear, founded in 2019, ships its own product roadmap as a live page on its site, with statuses like 'in progress' and 'shipped' that match what the company is actually doing. The transparency doubles as a sales tool, since enterprise buyers can see the cadence before they ever talk to sales. By 2023 Linear had crossed 10,000 paying teams running on that public-by-default model.
