It’s raised $23M+ in all.

Hubble, a direct-to-consumer contact lens brand, has closed on a $16.5MM Series A investment round.

The round, which brings Hubble’s total financing to $23.7 million, will allow the company to invest in marketing and advertising and to buy more inventory, according to a press release.

Since launching in late 2016, Hubble "has grown at a rapid rate, acquiring thousands of new customers each week and an extensive network of hundreds of partner doctors, in less than 3 months," the release stated.

The startup recently extended its lens powers to a range of -0.50 through -12.00. With the new funding, the firm plans to "purchase a substantial inventory of toric lenses to support customers with astigmatism and roll out new product extensions, including eye drops."

Hubble's model is based on selling daily lenses via a $30/month subscription service.
