Tech.eu calls the five backers; TFN writes that the round was 'led by' all five, so no single lead is recorded. Tech.eu also lists founders and hyperscaler directors, and TFN angels, none by name. The founder says the seed combines two rounds raised over the past year. Both outlets quote the company.
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.
