    Causal Chain

    Derived · heuristic

    This is our reading of the causal chain — separated from the verifiable facts above. Timeline dates, funding numbers and filings are facts (see methodology); root / proximate / terminal attribution is judgement based on public evidence.

    Root cause

    Structural mismatch between burn rate and revenue growth: capital was consumed on scaling before unit economics turned positive, leaving no bridge when the next round failed to close.

    Contributing factors
    • Sector context: Ride-hailing in UK, 2 years of runway.
    Terminal event

    2016: cessation of operations after failing to secure additional capital or a strategic buyer.
