How Beth Cast Turned Her Personality Into a Multi-Platform Brand

Going viral can get you noticed, but building a lasting career takes much more than a few popular videos. 

That's exactly what Lizbeth Castañeda, aka Beth Cast, has done. 

For the past nine years, the Gen Z Mexican influencer has successfully turned her popularity into a personal brand that has stretched far beyond the internet. 

With nearly 30 million followers across social media, a bestselling novel, a Forbes cover, a hosting role with GQ, and brand partnerships with some of the world's biggest companies, Beth Cast has become one of Latin America's most successful Creators.

Her story shows what can happen when you use each platform for a different purpose and build a business that doesn't depend on any single app.

From YouTube to Everywhere: How Beth Cast Got Started

Like many successful Creators, Beth Cast didn't become an overnight success. 

She began her content career in 2017 when she launched her first YouTube channel. Her videos consisted of family-friendly content and 24-hour challenges, experimenting with trends and trying to gauge what connected with her viewers best.

She eventually took a break from the platform after she started exploding on TikTok and Instagram. Her short-form videos, which included rapid facts about "things you don't know" and humorous skits, helped her find the right formula that made her stand out on both platforms.

One of her signature introductions, "I'm the one with the fun facts, and this is my only account," became instantly recognizable and helped reinforce the genuine personality her audience had come to trust. 

Cast's success was ultimately attributed to her personality. Rather than trying to act like a celebrity, Beth felt like the funny, knowledgeable friend everyone wanted to hear from.

Beth Cast's Platform Strategy: Three Platforms, Three Styles of Content

What makes Beth Cast stand out isn't just that she's active on multiple platforms-it's that each one serves a different purpose. 

While many Creators tend to repurpose their content and post the same videos everywhere, Cast uses each of her platforms to play to their strengths: TikTok (short-form videos), Instagram (videos and images), YouTube (long-form content).

Together, these platforms function as a single brand for Cast, with each helping her grow her audience and business in different ways.

TikTok: The Platform That Built Her Audience

TikTok is where Cast found her biggest audience and established the style she's known for today.

Her videos are a hodgepodge of rapid-fire facts, dance videos, and funny skits featuring awkward social interactions and relationship humor.

By mixing comedy with interesting facts and her own personality, she creates content that feels fun, authentic, and easy to share.

One of Beth's biggest strengths is that she doesn't simply copy whatever is trending. Instead, she takes popular sounds, formats, and ideas and adds her own sense of humor, making each video feel unique. 

She also regularly collaborates with Creators like Kim Migneault and La Granja del Borrego, introducing her content to new audiences while keeping the collaborations natural and entertaining rather than feeling like advertisements.

The results speak for themselves. Beth has built an audience of 16.9 million TikTok followers and averages 7 million views per video, making her one of the most engaging Creators in Latin America, according to her stats on StayOnSocial. 

Because she posts almost every day, her audience continues coming back for new content, turning casual viewers into loyal fans who follow her across her other platforms as well.

Instagram: Building a Stronger Connection With Fans

While TikTok helped Cast grow her audience, Instagram is where she builds deeper relationships with her 7 million followers. 

Instead of focusing only on comedy, she shares a mix of fashion, travel, friendships, behind-the-scenes moments, and everyday life that gives people a better look at who she is outside of her videos. It makes her feel more relatable and helps followers connect with her on a more personal level.

Cast also makes smart use of Instagram Reels by reposting many of her most successful TikTok videos, allowing her best content to reach a different audience without having to create everything from scratch. 

At the same time, she uses captions to share personal thoughts, stories, and moments of gratitude that don't always fit into a short video. Those small touches help strengthen the trust she's built with her audience and keep people invested in her journey.

Instagram is also where many of Cast's brand partnerships come to life. She has worked with companies like Spotify México and Coca-Cola, weaving sponsored content naturally into her posts so it feels like a genuine recommendation instead of a traditional advertisement. 

YouTube: A Place to Show Audiences the Real Beth Cast

Although her YouTube following is a bit smaller than her TikTok and Instagram followings (with a subscriber count of 3.41 million), Cast's channel has quickly become an important part of her brand's growth. 

Along with reposting her most popular TikTok videos as Shorts, Cast has spent the past year creating long-form content that not only offers viewers more variety in entertainment but also provides a bigger platform to highlight Cast in real-life situations that bring out her authentic self. 

Whether it's getting personal and answering questions, doing shopping and food experiments, or going on 24-hour adventures to exciting destinations, her YouTube channel has enabled her to share an aspect of herself that TikTok and Instagram can't quite capture.

This longer format has proven to be a natural fit for Cast, whose personality thrives when given room to breathe. 

Unlike the split-second comedic timing for which her TikTok audience knows her for, YouTube lets her ramble, react, and be genuinely surprised, and that unscripted quality is exactly what her fans show up for. 

Comment sections on her long-form videos frequently reflect the same sentiment: viewers feel like they're hanging out with her, not just watching her.

The results back that up. YouTube is currently her fastest-growing platform by percentage, gaining thousands of new subscribers every month as the algorithm rewards her consistent uploads and the platform continues to push long-form content to new viewers. 

For brands, that growth trajectory matters just as much as the raw numbers; it signals an audience that's actively expanding, not just loyal.

Beyond Social Media: Expanding Her Brand

One of the biggest moments in Cast's career didn't happen on TikTok, Instagram, or YouTube. Instead, it came when she proved she could turn her online audience into success beyond social media.

In 2020, Beth published her debut novel, Status: Jugando con Fuego. At a time when many Creators were still figuring out how to make money online, her book became a bestseller and quickly sold out.

It showed that the trust she'd built with her audience was strong enough to inspire people to support her outside of the apps where they first discovered her.

The book wasn't simply a side project-it was a natural extension of the storytelling skills she had already developed through her content. 

Years of entertaining audiences with relatable stories, humor, and creative ideas helped establish her as someone people genuinely wanted to hear from.

Her success as an author proves an important lesson for Creators: when you build a loyal community around your personality and creativity, your audience is often willing to follow you wherever your career takes you.

From Social Media Star to Industry Recognition

As Beth Cast's audience grew, so did the opportunities outside of creating videos.

What Creators Can Learn From Beth Cast

Beth Cast's success shows that building a Creator career takes more than going viral. 

Social media trends come and go, algorithms constantly change, and what works today might not work tomorrow. 

However, the Creators who continue to grow are the ones who build genuine relationships with their audience and create a brand that can succeed beyond any single platform.

One of Cast's biggest strengths is her understanding that every platform has a different purpose.

She uses TikTok to reach new viewers, Instagram to build stronger connections with her community, and YouTube to experiment with new ideas and longer-form content. 

And instead of posting the exact same thing everywhere, she develops a strategy that plays to each platform's strengths while keeping her personality consistent across them.

Her career is also a reminder that your content can open doors far beyond social media. 

By building trust with her audience first, she was able to expand into publishing, hosting major events, landing high-profile brand partnerships, and becoming one of Latin America's most recognized Creators.
