A website was listed for this organisation, but we could not confirm it belongs to the firm that wrote these cheques. Either the site never mentions them, or it turned out to be a different company sharing the name. We show neither it nor anything read from it. Tell us the right one.

An announcement gives the size of the round, not the size of this investor's cheque: the only rounds that imply a cheque are those where they were the sole named investor.

Weaker than a round we watched, stronger than a list somebody sold us. A firm is far less willing to put a company on its own site that it never funded.
