Outside reality television, Guelli has an established career in skincare and beauty. She developed her first skincare products through personal experimentation, launched her own brand, and later expanded into makeup.

Who Is Jacqueline “Jax” Guelli?

Jacqueline Guelli, professionally known as Jax, is a beauty entrepreneur from the Boston area of Massachusetts.

She founded JAX SKINCARE after developing an interest in skincare, makeup, and product formulation. Her professional background includes working as a licensed esthetician and makeup artist.

Guelli became known to a wider audience when she joined the cast of Love Is Blind Season 11. Netflix introduced her as an entrepreneur who wanted a relationship with someone who would support her professional ambitions.

Her television appearance brought attention to a career she had been developing for nearly a decade before joining the dating series.

Jacqueline “Jax” Guelli Age

Jax Guelli was 31 years old during Love Is Blind Season 11 in 2026, according to Netflix’s official contestant profile. Netflix also identifies her zodiac sign as Taurus.

Early Life and Family Background

Jacqueline “Jax” Guelli developed an interest in the beauty industry at a young age. In an April 2018 interview with Boston Voyager, she explained that she began working in skincare when she was 18.

Beauty and personal care were already familiar parts of her family environment.

Her mother worked as an esthetician, while her sister was a hairdresser and business owner. Guelli identified both women as important influences on her decision to establish a business of her own.

Their professional backgrounds helped shape her interest in skincare, beauty products, and entrepreneurship.

JAX SKINCARE

Jacqueline Guelli founded JAX SKINCARE in Boston in 2017.

According to the company’s official history, the business began when Guelli started developing skincare formulations in her kitchen. She experimented with different oils before creating a product that became popular with her clients.

That original formulation became the foundation of the company’s product line.

The brand initially focused on a facial oil known as Balance Oil, later marketed as THE OIL. Guelli subsequently expanded the business into additional skincare products.

JAX SKINCARE emphasizes simplified routines, carefully selected ingredients, and minimalist packaging.

The company’s development reflects Guelli’s professional experience as an esthetician and her interest in creating products based on her own approach to skincare.

How Did Jax Guelli Start Her Skincare Business?

Jax discussed the early development of her business in an April 10, 2018, interview with Boston Voyager.

She explained that she began experimenting with skincare formulations after finding a combination of ingredients that worked well for her own skin.

Encouraged by those results, she decided to develop products for other people.

Guelli initially focused on creating a simple skincare routine built around facial oils. She also wanted the products to have packaging that appealed to customers interested in a modern, minimalist appearance.

At the time of the interview, she was working to expand the product range and introduce the brand to additional retailers.

Her account provides a documented history of the business before her appearance on reality television.

MADAME JACQUELINE BEAUTY

Jax Guelli later expanded her beauty business by introducing MADAME JACQUELINE BEAUTY, a makeup line associated with JAX SKINCARE.

According to the company’s official website, the makeup collection developed from her belief that effective makeup application begins with good skincare.

The products follow a similar minimalist approach to the original skincare line.

The expansion allowed Guelli to build on her experience in makeup artistry while continuing to develop the skincare business she founded in 2017.

Both brands form part of her professional identity outside television.

Love Is Blind Season 11

Jacqueline “Jax” Guelli joined the cast of Love Is Blind Season 11, which premiered on Netflix on October 14, 2026.

The season featured 30 singles from the Boston area participating in a dating experiment that begins with conversations in separate rooms known as pods.

Contestants develop connections without seeing one another and must become engaged before meeting face-to-face.

Netflix introduced Jax as a 31-year-old entrepreneur who had struggled to find a compatible partner in the Boston dating scene.

In her official cast profile, she explained that her business was an important part of her life and that she wanted a partner who would respect her professional ambitions.

She also described enjoying simple activities, including morning coffee, walking her dog, and spending time together at home.

Her approach to dating emphasized stability, compatibility, and shared expectations about the future.

Other contestants from the Boston season included orthodontist Sahar Mostafavi and former professional baseball player Scott Shuman.

Jax Guelli and Scott “Stew” Stewart

Spoiler warning: This section discusses events from the October 14, 2026, premiere episodes.

Jax developed a relationship with Scott “Stew” Stewart during the pod stage of Love Is Blind Season 11.

Stew was introduced as a 34-year-old director of engineering who enjoyed skiing, boating, and traveling.

The pair discovered several shared interests, including their preferences for design, travel, and lifestyle.

They also connected over their appreciation for The Phantom of the Opera.

Their conversations extended beyond romance to practical questions about finances, living arrangements, and the type of life they wanted to build together.

Despite their connection, Jax became concerned when Stew revealed that he had never previously been in love.

She later explained that the admission raised questions about his emotional experience and readiness for a serious commitment.

However, the concern did not immediately end their relationship. Stew eventually proposed, and Jax accepted.

Why Did Jax Guelli Leave Stew on Love Is Blind?

Jax left the experiment shortly after meeting Stew face-to-face during the Season 11 premiere episodes.

In an October 14 interview with Netflix’s Tudum, she explained that the experience had become overwhelming and that the romantic connection she expected did not translate into their first in-person meeting.

She also expressed disappointment with Stew’s proposal, which she felt had not been sufficiently personal.

When they finally met, Jax said the interaction felt different from the conversations they had shared in the pods.

She subsequently decided to leave the experiment without first explaining her decision directly to Stew.

Importantly, Jax later clarified that her departure was not simply a reaction to his physical appearance.

Reflecting on the situation, she acknowledged that she should have handled the conversation differently and expressed regret about leaving without providing an explanation.

Stew told Netflix that he found the reveal uncomfortable but did not blame either of them for how the experience unfolded.

Are Jax Guelli and Stew Still Together?

Their final relationship outcome had not been established by the first five episodes released on October 14, 2026.

Jax left the experiment following their face-to-face meeting, but Netflix’s official episode recap indicated that their story had not necessarily concluded.

Episode 5 ended with the possibility of another meeting between the two in Boston.

Netflix’s official relationship tracker therefore listed their status as unresolved following the premiere.

The next episodes were scheduled for October 21, 2026.
