    The release names no lead and calls the backers Zone II, CC.VC and angels from the finance sector; Fortune, which the company briefed, puts the angels in defence and finance and says the round is all equity. Fortune's piece carries a correction striking Fifth Wall from its own list of this round's investors, after a disclosure error by the company before publication; the release itself lists Fifth Wall as an existing investor, not as part of this round. The valuation is Fortune's, from an unnamed person, on a basis it does not give.

Research entries are the timeline's graded entries that name this company. A level grades one claim, not the company, and a blank can mean the record has not caught up rather than that nothing was published.
