Lark, which launched a wearable silent alarm on-stage at TechCrunch’s Disrupt conference back in 2010, has raised $3.1 million of an intended $3.6 million round of funding, according to a filing with the Securities and Exchange Commission.I’ve emailed the company and its CEO Julia Hu for confirmation, and I’ll update this post if I hear back. The filing doesn’t specify the investors in the new round, but intriguingly, it does identify Weili Dai, president and co-founder of Marvell, as as member of its board of directors.
