Why This Person Is Included
KJ Miller was among the first sixteen Black women in American history to raise $1 million or more in venture capital. She and Amanda Johnson built Mented Cosmetics from a market insight into a nationally distributed brand with $9 million in VC backing and a 2024 acquisition. The outcome is the exit. The pattern — identify the ignored market, raise the institutional capital that the market said was unavailable, build the brand that proves the market wrong — is the curriculum.
The Story
KJ Miller — Kristen Jones Miller — attended Harvard Business School, where she and Amanda Johnson identified the nude lip shade gap for darker skin tones and decided to fill it.1 Miller's background before HBS included retail and consumer goods strategy. Johnson's background included marketing and brand development. Together they had the product discipline and brand capability to take the Mented concept to market.
They launched Mented in 2016 with a direct-to-consumer e-commerce model targeting darker skin tones with nude lip shades specifically formulated for melanin-rich complexions.1 The founding insight was not new — Black women had discussed this gap for decades. What was new was the infrastructure: DTC e-commerce made it possible to reach a national audience, and Instagram made it possible to build brand awareness, without traditional retail distribution.
The VC Fundraise
Raising venture capital for Mented required overcoming two compounding constraints: the 'niche market' framing applied to beauty products for darker skin tones, and the racial and gender funding gap that made it difficult for Black women founders to access institutional capital regardless of market thesis.2 Miller and Johnson raised $1 million in 2017 — among the first sixteen Black women in American history to reach that milestone.2 Total funding reached $9 million.
The Acquisition (2024)
West Lane Capital acquired Mented Cosmetics in May 2024.3 Over eight years, Miller and Johnson had built Mented from a concept at an HBS cocktail party to a nationally distributed, venture-funded brand with a strategic exit. The acquisition is the market proof: the category they proved existed was real enough to attract institutional buyers at an exit.
Constraints & Tradeoffs
Proving a Market That Investors Had Decided Didn't Exist
Miller and Johnson's core challenge was epistemological: how do you prove a market size to investors who have decided the evidence doesn't justify the thesis? The mainstream beauty industry had underinvested in darker skin tone products for decades — which meant there was no large-scale commercial data demonstrating demand at scale, because scale had never been tried. The absence of scale became the evidence for the niche label, which justified the absence of investment in scale.
Miller's approach was to use available proxies: social media conversation, customer waitlists, and early direct-to-consumer sales that demonstrated willingness to pay at premium price points. Each piece of evidence required translation — converting it from 'this many people follow this Instagram account' to 'this implies this addressable market size.' The translation was part of every fundraising conversation and required sustained patience with investors who required more evidence than the data could provide.
What Actually Happened
Acquisition and Category Proof
The West Lane Capital acquisition of Mented in 2024 closed a chapter that began with a Harvard Business School cocktail party conversation in 2015. Miller and Johnson had demonstrated that a beauty brand founded by Black women, for darker skin tones, with no major brand backing, could raise institutional capital, build national distribution, and achieve a strategic exit. The thesis — that the market was real — was proved by the business's existence over eight years.
Miller has continued to be active in the Black women founder community — speaking at conferences, mentoring entrepreneurs, and advocating for the structural changes in venture capital access that Mented's fundraising experience made visible. The Mented story is taught at several business schools as a case study in market creation and minority entrepreneurship financing.
Pattern Extraction
Miller's pattern mirrors Johnson's: use direct-to-consumer channels to build market proof before scale, use that proof to access institutional capital, use the capital to scale, and use the scale to achieve the exit. The pattern is the same pattern that every consumer brand founder uses — the differentiator is the need to simultaneously make the market existence argument that white founders making comparable products rarely need to make.
Frequently Asked Questions
- What was KJ Miller's highest level of education? ▾
- KJ Miller holds a BA from Harvard College (2008) and an MBA from Harvard Business School (2014). Before co-founding Mented, she worked as a retail buyer at Sears Holdings and as a consultant in Deloitte's retail practice. She had no prior cosmetics industry experience before founding Mented.
- What is KJ Miller's net worth? ▾
- No publicly documented net worth figure is available for KJ Miller. Mented Cosmetics raised approximately $9 million in venture capital before being acquired by West Lane Capital in May 2024. No acquisition price has been publicly disclosed.
- How did KJ Miller and Amanda Johnson formulate Mented products without cosmetics experience? ▾
- After cosmetic manufacturers either quoted prohibitively high minimum order quantities or could not formulate nude shades from a melanin-first baseline, Miller and Johnson self-formulated. Miller found a YouTube tutorial showing a woman making lipstick at home using cosmetic-grade oils, waxes, micas, and pigments. The founders ordered supplies and spent every Saturday and Sunday in Johnson's kitchen iterating on the formula through 2015 and 2016. Miller's retail and supply chain background informed ingredient sourcing and unit economics. The six-shade Capsule Collection emerged from this process.

- What was the significance of Mented raising $1 million in venture capital? ▾
- When Miller and Johnson raised $1 million in 2017, they were among the first sixteen Black women in American history to raise $1 million or more in venture capital. The raise required overcoming two compounding barriers: investors framing beauty products for darker skin tones as 'niche' rather than underserved, and the structural racial and gender funding gap that limited Black women founders' access to institutional capital. Mented's total funding reached approximately $9 million before the 2024 acquisition. [Source: record bio, Block b117]
- When did Mented expand beyond lip products? ▾
- Miller and Johnson planned the expansion sequence from the outset. They described 2017 as 'the year of lips.' Nude lip glosses were added in fall 2017. Eye and cheek products launched in 2018. Foundation and complexion products followed in late 2018 and 2019. The full-line brand Miller had always described was built one category at a time, each funded by the traction of the one before. West Lane Capital acquired Mented in May 2024. [Sources: BET, July 2017; Side Hustle Pro Episode 298, 2022; record bio]
