Chanel backed her silkworm-sourced healthier fabric care.
When 38-year old Rebecca “Beck” Lacouture underwent three grueling months of chemotherapy a decade ago, her skin became painfully tender. So, an oncologist advised her to avoid a list of harmful chemicals commonly found in skin care products. A researcher with a PhD in biomedical engineering, Lacouture turned this advice into Evolved by Nature--a startup that uses proteins found in silkworm cocoons to manufacture a "liquid silk" alternative to damaging ingredients in skin care, consumer goods, and textiles. The company, which launched in 2013, recently won the backing of luxury fashion and beauty label Chanel, bringing its fundraising totals to $51 million. It also doubled revenue this year. “In the last year or so, we’ve realized that what we’re really creating is a chemistry company,” says Lacouture, who is now cancer-free. “Our silk can potentially be used anywhere." --Zoë Henry
Women spend over $70 million a year on her chic, personalized workwear.
Women’s workwear brand M.M.LaFleur first gained a following by curating “Bento Boxes” of coordinating looks—think tailored suits and sharp dresses—that busy women could try on at home. The strategy helped M.M.LaFleur hit more than $70 million in revenue in 2017—but it won’t keep the brand growing. More women are dressing casually for work, and an increasing number still want the in-store experience. LaFleur has responded to these trends by leaning hard into seven brick-and-mortar retail showrooms, where same-store revenue is up 13 percent from 2018. The company is also designing more lines for the formal and casual ends of their 25-55-year-old customer base—launching a high-end suiting collection this fall and designing a machine-washable, wrinkle-resistant travel line. “Releasing these two collections allows us to target both the C-suite exec and the younger, more casual woman on the go,” says co-founder and CEO Sarah LaFleur. --Lindsay Blakely
She put the work of African artisans on the covers of American magazines.
Look away from Michelle Obama’s dazzling smile on the cover of December’s Essence magazine and you might notice a graceful brass ring and necklace—both from Soko. That photo “was such a validation of what we do,” says Catherine Mahugu, who co-founded the business with Gwendolyn Floyd and Ella Peinovich. After Obama’s cover, Oprah Winfrey flashed a Soko bracelet and earrings on the cover of April’s O magazine— and fashion pace-setters like Reformation, Zolando, Amour Vert, and Nordstrom’s have taken up the brand. But what’s more important to Soko’s co-founders is the income provided for the 2,300 artisans in Mahugu’s native Kenya. To advantage African workers, Mahugu also just launched Chiswara, a company trying to digitize the agricultural supply chain, first by partnering with small farmers in Kenya to sell their coffee internationally. “In the U.S., we pay $5 for a cup of coffee, but the lives of the farmers don’t reflect that,” says Mahugu, whose parents grew up on coffee farms. “We are giving farmers a seat at the table.” --Leigh Buchanan
This Jimmy Choo co-founder is taking luxury shoe sales direct to consumer.
Tamara Mellon is the past of footwear retail and its future. After co-founding Jimmy Choo, Mellon launched a namesake shoe line that went bankrupt. She parlayed the lessons of that bankruptcy into a leaner, direct-to-consumer brand that she’s determined will be the luxury shoe of choice. By doing its prototyping stateside while keeping production in Italy, Mellon’s namesake company has cut the typical development time on a new style from three months to one. That’s increasingly necessary as Mellon ditches the industry’s standard seasonal collections in favor of frequent, small releases. Drawing from a $91 million VC war chest, which includes backing from private equity firm NEA, Tamara Mellon opened its first store in November. It’s currently doing an impressive $3,000 per square foot--and doubling year-over-year sales. --Kimberly Weisul
She uses her platform as the founder of a $100 million fashion brand to support women-owned businesses
Two decades into building her $100 million namesake brand, New York City clothing and handbag designer Rebecca Minkoff is still on the rise--with space in 900 stores worldwide and business growing by double digits--and she's taking other female entrepreneurs with her. The Female Founder Collective, which Minkoff launched last year, is a network of women-run businesses boasting a seal that its 50,000-plus Instagram followers can recognize, support, and promote. The group harnesses the talents of its members--from Draper James founder Reese Witherspoon to scrappy Nashville-based meal-delivery company Dinner Belle--"to enable and empower female-owned and led businesses to positively impact our communities, both socially and economically." --Christine Lagorio-Chafkin
