Tahlia Sisney is Reshaping How Advisors Work
Spreadsheets, invoices, and unread emails littering the tabs of a laptop are what Tahlia Sisney, founder of The Art Girl Advisory was dealing with when she started her advisory. The chaos of starting a new company and managing the host of relationships it takes to be an art advisor ended up being overshadowed by multiple spreadsheets and invoicing systems. The Sotheby’s Institute of Art alumna decided to break down the barriers that advisors face in their businesses by creating a streamline software called Opisfolio.

Some may be familiar with Sisney as she is known on social media as ‘the art girl’ with 47.1k followers on TikTok, 18.7k followers on Instagram and 6.3k subscribers on her Substack. However, Sisney did not start her journey in the art world. After graduating from Baylor University with a neuroscience degree, her interest and love of art drew her to The Sotheby's Institute of Art in New York City to pursue a masters in Art Business. During her time at the Sotheby’s Institute she worked as an independent curator and a graduate assistant. She later went on to be an intern at the Peggy Guggenheim Museum in Venice. In the fall of 2024 she moved back to NYC to build her own advisory.
During the creation of The Art Girl Advisory she found gaps in the systems that advisors were operating with, limiting the processes and efficacy of advisors globally. The frustrations she faced led her to create her own software program called Opusfolio. The name comes from the latin term ‘Magnum opus’ which when translated means great work, and is often a term used by artists to highlight their greatest works. Sisney chose this to represent the software being her great work. The folio added to the end highlights the use of portfolios in both the artist aspect but also the financial world. This name is especially significant to the combination of art and financial investments being the great culmination of art advisors work.

Opusfolio is a platform designed for art advisors by an art advisor. From Sisney’s experience managing an invoicing platform, client spreadsheets, artwork details and more in a range of different documents became challenging especially in a personal professional capacity as advisors often have. Opusfolio serves as a software to replace ‘spreadsheets, email threads, Word proposals, PDF invoices, scheduling tool, and file storage with one system.’ per the website. The software uses built in invoices and calendar syncing tools while acting as both a client management tool and a CRM based product allowing for both onboarding new clients and servicing them. Sisney developed and thought through everything she needed and gave it to the community of advisors operating globally.
Not only does Opusfolio help art advisors manage their businesses but Sisney also established The Easel, a place for art advisors to have forums, and meet to collaborate and grow. The Easel operates through Opisfolio as a streamline place for communication. Sisney highlighted that advisors often work independently so having a community that can discuss and ask questions that would not get answered elsewhere is special. This community also brings together the generations of art professionals working as advisors, letting accomplished advisors aid newcomers while they inspire with new ideas and tastes.
Sisney launched Opusfolio in 2025 and submitted it to the Sotheby’s Institute 2026 Gavel Competition where she was able to present her idea through the Enterprise Studio that has helped students turn brilliant ideas into successful business ventures. Although Sisney’s platform was not picked as the 2026 winner, her platform is doing incredible work for advisors, as users are located across the world.
