Trellis

Trellis is a Y Combinator-backed company that autonomous Agents for Short Term Rentals. Based in San Francisco, USA, the company participated in the Spring 2026 batch of Y Combinator.

Short-term rental operators suffer from diseconomies of scale. As listing count grows, operational complexity increases exponentially, managers lose control, reviews drop, and so do rates and homeowner retention.

Most are stuck between 10 and 50 listings, using 5 to 10 different software tools, none flexible enough for their needs. There is no unified data layer of their company. They navigate in the dark, reacting to problems rather than delivering hospitality.

Trellis was part of Y Combinator's Spring 2026 cohort, has a team of approximately 6 employees, and is actively operating.
