    Root Causes

    Repeated market pivots (New York, then London) without finding product-market fit
    Extremely low revenue relative to funding raised and years of operation
    Confused customer understanding of the invite-only 'sublet club' model
    Founder controversy and PR missteps undermining trust

    Kiki was a rental/subletting marketplace founded by New Zealand entrepreneur Toby Thomas-Smith. Backed by Australian VC Blackbird, the company operated across four countries over 7.5 years, raising over $5 million. Despite this runway, Kiki struggled to find a sustainable business model, shutting down in New York before relaunching in London as Kiki Club, an invite-only sublet community. The London reboot generated only ~$18,700 over four months amid customer confusion. The brand also suffered when Thomas-Smith posted an April Fool's Day joke on LinkedIn claiming Kiki was shutting down. In March 2026, Thomas-Smith confirmed after 7.5 years and $5m+ raised, Kiki was 'finally shutting down.'
