Lully

A YC-backed hardware company that reported roughly $2.2 million raised between 2014 and 2016, all of it through press interviews rather than a public securities filing. No Form D has been found for the company, and it appears to have stopped selling its device by 2021.

What the filings show

No Form D filing has been found for Lully, Inc. under its own name in SEC EDGAR or in the compiled research record assembled for this profile. That is unusual for a company that raised institutional money across at least two named funds, Two Sigma Ventures and the Stanford-StartX Fund, and a hardware accelerator, Highway1. It means every dollar figure in the table above comes from a press interview with a founder, not from a document filed with a regulator, and none of it can be independently checked against a price, an investor count or a closing date.

Reading the numbers

  1. The reported total nearly doubled in three months.TechCrunch put seed funding at $920,000 in March 2015. By June 2015, NPR reported the company had “just wrapped up its Y Combinator seed funding after raising $2.1 million.” Founders described this as the same round closing, not a new one, so the jump most likely reflects additional investors coming into an already-open round rather than a second financing.
  2. The number barely moved after that.CNBC’s $2.2 million figure, reported in March 2016, is only $100,000 above the $2.1 million reported nine months earlier. Read plainly, that suggests the seed round was effectively closed by mid 2015, with no new institutional round disclosed in the following year.
  3. No filing means no independent check.Four investors are named across the company’s own materials and CNBC’s report: Y Combinator, Two Sigma Ventures, the Stanford-StartX Fund and Highway1. None of the sources breaks out how much any single investor put in, and with no Form D on record there is no way to confirm the round’s structure, valuation or investor count beyond what the founders told reporters.
  4. The money funded a real, shipping product, not just a prototype.By March 2016 the company had shipped a second hardware version, the Sleep Guardian Plus, and reported more than 1,200 units sold. That is a meaningful operating signal even without a securities filing to confirm the capital behind it.
