Quick Facts

Hill House Home has sold 1.2 million Nap Dresses at an average price of $210, with fashion now accounting for 87% of revenue.
The brand has raised $30.4 million across three funding rounds and is valued at more than $150 million.
For its 10th anniversary in 2026, Hill House plans two to three new store openings and a series of brand collaborations.

Nell Diamond launched Hill House Home in 2016 as a direct-to-consumer bed and bath startup. By 2026, she had built it into a fashion and lifestyle brand valued at more than $150 million, powered largely by a single product: the Nap Dress.

The smocked gown, designed to be worn day or night, debuted in August 2019. Its tartan winter version sold out quickly. Then the pandemic hit.

In 2020, consumer searches for the term “nap dress” averaged 4,400 per week between July and September, a 423% increase from the prior year, according to Trendalytics. Hill House had trademarked the term. The brand posted 275% overall growth that year. The Nap Dress category alone grew 1,120%.

The momentum compounded fast. On Feb. 10, 2021, a new collection sold $1 million in inventory in the first 12 minutes. By end of day, the brand had generated more revenue than in all of 2019. Hill House then logged 300% growth for three consecutive years.

Diamond had kept the company lean before that breakout. She hit profitability in 2018, two years after founding. She avoided wholesale in favor of digital DTC, which insulated the brand during pandemic-era retail disruptions that hurt competitors.

The top 15% of Hill House customers have purchased an average of 12 dresses each. Diamond said 2024 was the company’s best year, and 2025 was tracking ahead of it.

To fund expansion, Diamond raised $20 million in September 2022, following a $6 million Series A tied to the brand’s influencer-driven growth. Total funding stands at $30.4 million across three rounds from five investors.

Hill House has used that capital to build physical retail. The brand now operates stores in New York City, Nantucket, Charleston, Dallas, Greenwich, and Atlanta. A Boston location in the Seaport District opens this summer. The Charleston store, three times the size of any prior location, includes a coffee and soda bar called Nell’s, marking the brand’s first move into hospitality.

The wholesale strategy has also shifted. Hill House is no longer avoiding outside partnerships. In March 2026, it launched a collection with Pottery Barn Kids and Pottery Barn Teen covering furniture, bedding, wallpaper, and nursery goods. In June 2026, it launched a Williams Sonoma outdoor entertaining collection featuring garden-inspired dinnerware, striped linens, and vegetable motifs.

“Hill House Home is famous for its whimsical aesthetic that really resonates with our customers,” said Allison Spampanato, SVP of product development at Pottery Barn Kids and Teen.

For its 10th anniversary this year, Diamond plans two to three additional store openings and more brand collaborations. Fashion, which stood at 88% of sales in 2022, now sits at 87%, confirming the business mix has held steady as the company scales its physical and wholesale channels.

Hill House started as a linen brand solving a niche home goods problem. It now sells 87 cents of every dollar in fashion. The Nap Dress made that possible. The question Diamond is answering now is how large a lifestyle brand can be built around it.
