Kierin NYC emerged in 2018 from the vision of Mona Maine de Biran, a former international model and lifestyle blogger who wanted to tell authentic New York stories through fragrance. Together with her husband Didier Maine de Biran, who brought over two decades of experience from prestigious houses like Chanel, Prada, and Bvlgari, she created a brand that challenges traditional perfume conventions.

The brand represents more than just fragrances – it embodies a philosophy of inclusion and sustainability. Kierin NYC deliberately creates gender-neutral scents, which they term "gender-all." This approach reflects the diversity and openness of New York, where people from all backgrounds come together.

New York City serves as the central inspiration for every creation. The energy of the streets, the art on the walls, and the stories of its people flow into each fragrance. Street art, graffiti, and tattoo art shape not only the brand's visual elements but also its rebellious soul.

The brand positions itself as "clean and conscious" – all fragrances are vegan, cruelty-free, and free from problematic ingredients like parabens and phthalates. These values aren't just marketing speak but reflect Mona's perspective as a mother who wants to create safe products for everyone.

This commitment to ethical practices extends to their supply chain partnerships with companies like Robertet, known for sustainable natural raw materials. The brand's PETA certification and toxin-free formulations demonstrate their serious commitment to responsible luxury.

The heart of Kierin NYC lies in the four original fragrances created in 2018 with perfumer Mathieu Nardin. Nitro Noir combines Italian bergamot, pink pepper, and iris into a hypnotic composition that bridges classic elegance with modern rebellion. Sunday Brunch captures the lightness of a perfect weekend morning – with Earl Grey tea, bergamot, and jasmine creating a luminous citrus experience.

10 a.m. Flirt tells stories of urban seduction through fig, gardenia, and sandalwood. Santal Sky combines cardamom, saffron, and creamy sandalwood into a meditative woody experience.

Collaboration with award-winning perfumer Jérôme Epinette brought newer creations to life. Pier NY interprets the salty air of New York's piers with salted fig, sage, and seaweed. Rose Ink connects Damask rose with cedarwood for a modern floral statement.

Particularly noteworthy is ScentXone, a complex woody-spicy composition featuring cognac, wild honey, and myrrh. These fragrances stand out through high concentration and sustainably sourced ingredients developed with partners like Robertet, ensuring both quality and environmental responsibility.

Kierin NYC positions itself cleverly in the accessible luxury segment. With 50ml bottles priced around $89 USD, the brand offers premium eau de parfums at a fair price point. This strategy makes niche fragrances available to a broader audience without compromising on quality.

The target audience includes "young people of all ages, colors, and nationalities" – individualists who appreciate urban vibes and make conscious purchasing decisions. These customers seek authentic fragrances that express their personality while maintaining ethical values.

Distribution primarily follows a direct-to-consumer model through kierin-nyc.com. This digital strategy enables direct customer contact and authentic storytelling. Additionally, the brand is available through online retailers like Amazon Luxury Beauty, ASOS, and Harvey Nichols.

The brand expanded to the UK in 2019 with a digital campaign and pop-up at London's Boxpark Shoreditch. Such activations create unique experiences – customers could even design their own bottle labels.

Sustainability shapes packaging too: opaque glass bottles protect fragrance oils from UV light, natural paints and paper-based packaging avoid unnecessary plastics. Kierin NYC actively encourages recycling and supports customers in disposing of empty bottles responsibly.

This holistic approach makes the brand a pioneer in responsible luxury. The combination of ethical practices, urban inspiration, and accessible pricing creates a unique value proposition. Customers don't just buy a fragrance – they invest in a brand that reflects their values while delivering exceptional olfactory experiences that capture the essence of New York City's dynamic spirit.
