After Morning Brew acquired the brand in 2022, Gatti Tassin paid out her remaining contract and reclaimed full ownership. The Money with Katie Show aired its final episode on December 31, 2025, with a podcast hiatus beginning January 2026.
Katie and co-host Caro Claire Burke fulfilled their pledge to redirect 33% of net revenue from their independent Substack podcast, Diabolical Lies, surpassing their earlier $100K target for the year.
As part of a pilot initiative, Katie and co-host Caro announced a relaunch and gave listeners direct control over directing a quarter's worth of redistribution funds (~$30K), having already donated over $65K that year.
Published via Penguin Random House, the personal finance book for women earned Katie the title of national bestselling author, as noted across her platforms and promotional appearances.

Their YouTube bio reads: "cohost of Diabolical Lies 🔪 author of Rich Girl Nation 💅". The full audience and engagement breakdown is below.
Katiegattitassin reaches an audience concentrated in United States primarily through YouTube, and is best activated via Instagram Reels and Stories, TikTok branded content. As a finance creator they map naturally to brands targeting that space. With no brand deals logged yet, they read as an available, category-aligned partner for advertisers building early presence in the space. Engagement on YouTube runs around 4.9%, which points to an audience better suited to category-relevant, mid-funnel campaigns than to pure-reach buys. The channel's mix of Instagram Reels and Stories and TikTok branded content lets a sponsor choose between short awareness placements and longer, more detailed integrations. Because the audience follows finance content rather than arriving through untargeted reach, sponsorships that match the channel's subject matter tend to convert more efficiently than broad placements. A consistent, on-topic posting focus gives sponsors a predictable, brand-safe environment, lowering placement risk compared with broad, general-interest channels. Campaigns here are best measured on qualified engagement and consideration within the niche rather than on raw impression volume. For United States-focused brands in finance and related categories, Katiegattitassin offers a defined, creative-fit audience rather than broad, low-intent impressions.

Diabolical Lies is a podcast that Katiegattitassin cohosts, and it's one of the two headline projects she leads with in every platform bio alongside her book Rich Girl Nation.

Rich Girl Nation is a book authored by Katiegattitassin, and given that her content consistently revolves around money, culture, and class, the book appears to explore those same themes — likely around wealth identity, financial dynamics, and women's relationship with money.

Yes, Love Is Blind is a recurring subject in Katiegattitassin's content, reflected in her consistent use of the #loveisblind hashtag.
