What is The Sill?

The Sill is a New York City-based ecommerce and brick-and-mortar business that specializes in selling houseplants and related products. Since its launch in 2012, the woman-owned startup has gained a cult-following as a direct-to-consumer brand that focuses on making houseplants accessible and easy to care for. The company's mission is to bridge the gap between people and plants, bringing greenery into people's lives and creating a sense of well-being through nature.

The Sill offers a wide range of indoor plants, including popular varieties like pothos, snake plants, succulents, and fiddle-leaf figs, among others. The company also sells plant care accessories, such as planters, pots, soil, and fertilizers. In addition to an e-commerce store, The Sill operates seven brick-and-mortar locations where customers can explore and purchase plants in person.

One of the key aspects of The Sill's business model is its emphasis on education and customer support. Detailed plant care instructions, online resources, and workshops help customers understand how to care for their plants. This approach aims to empower plant owners, particularly those who may be new to gardening, by providing them with the knowledge and confidence to nurture their indoor greenery.

The Sill also offers a monthly houseplant subscription box and ships to customers nationwide.

Who founded The Sill?

Eliza Blank founded The Sill in 2012 on a simple premise: “plants make us happier, healthier humans.” 

What is The Sill's origin story?

When The Sill founder Eliza Blank moved from rural Massachusetts to New York City for college, she missed the lack of greenery in the city. However, she struggled to find houseplants to fill her NYC apartment. At that time, houseplants were not available online and the local gardening stores didn’t offer what she wanted. Upon her college graduation in 2007, Eliza had the concept for The Sill, but she had no idea how to launch it. 

So she took a job in brand strategy at the beauty brand Living Proof, and learned the basics of starting a business. She learned what she should do and what she didn’t want to do, namely go the venture capital route too early and make expensive mistakes. 

In 2012, Eliza quit her Living Proof job to pursue her business idea full-time. A co-worker from Living Proof joined her efforts, and they both put in their savings–a little less than $10,000 each–to get the company off the ground. They launched a Kickstarter campaign in April 2012 to raise $12,000, which they easily achieved. 

A Lean Startup

With a budget of $32,000, Eliza knew she would need to keep her initial costs low. Her brother loaned her office space and the creative team from his agency to help her with The Sill’s visual identity and website design. She sourced products from her own pocket, buying locally when possible. 

Soon after The Sill’s launch in June 2012, Eliza and her partner parted ways due to differences in business goals. Once they amicably dissolved the partnership, Eliza hired a marketing intern and started reaching out to her target audience through Instagram, newsletters, and The Sill’s blog. They also cold-emailed editors and gifted houseplants to build rapport. Eliza credits her media exposure with helping her get the word out about the business. She partnered with brands like DailyCandy and Refinery29. She also set up booths at local fashion and flea markets to increase exposure. 

While revenue was low from 2012 to 2014, Eliza was excited about her business and wanted to see where she could take it. By 2015, Eliza opened her first brick-and-mortar location in Chinatown in Manhattan. As The Sill continued to grow, the company began shipping nationwide, and Eliza realized her business was established enough to seek venture capital funds to take it to the next level. 

How was it funded?

Eliza and her partner used their personal savings and a 2012 Kickstarter campaign to fund the business launch. A few years later, Eliza took out an $80,000 small business loan from TruFund. In 2017, the startup turned to venture capital, raising $2.5 million in seed funding from a team led by Brand Foundry Ventures. Other venture capital funding for The Sill included $5 million in Series A funding led by Raine Ventures. 

What is the company’s valuation?

As a privately-owned company, The Sill does not have a publicly reported valuation. According to marketing intelligence platform PipeCandy, the startup’s estimated valuation is in the range of $50 million to $150 million.
