About
jiesen.ai is built and operated by a working group of CFOs, controllers, and AI company founders with 25+ years of operational accounting and finance leadership across public companies, private equity portfolios, multi-entity restaurant groups, and international finance build-outs, paired with direct product and market input from AI venture founders shipping at scale. The platform reflects work done across five M&A deals at a $3 billion Nasdaq semiconductor company, a Fortune 500 carve-out and post-merger integration, an end-to-end finance and accounting build for an integrated resort in greater China, a B2B embedded payments architecture for an AI media venture, and the live multi-entity controllership of a multi-unit hospitality group running on a 13-period operating calendar today.
jiesen.ai is not a Big 4 firm and is not trying to be one. It is built by operators, for operators — the controllers, CFOs, and deal teams who do the actual work.

Who builds jiesen.ai?+
jiesen.ai is built by a working group of CFOs, controllers, and AI venture founders with 25+ years of operational accounting and finance leadership. The platform reflects M&A and carve-out work at a $3B Nasdaq semiconductor company, a Fortune 500 post-merger integration, an end-to-end finance build for an integrated resort in greater China, B2B embedded payments architecture at an AI media venture, and live controllership of a multi-unit hospitality group today.
Is jiesen.ai a Big 4 firm?+
No. jiesen.ai is built by operators, for operators. The platform is designed for the controllers, CFOs, and deal teams who do the actual work — not for partners selling to other partners. The output reflects how a senior finance lead would think through the problem, not how a junior consultant would frame it in a deck.
How do advisory engagements work?+
Advisory engagements run through Jiesen Li Advisory — inbound only, no cold outreach. Scope is typically ERP migrations, post-merger integration, controllership stand-ups, or finance transformation for PE portfolio companies and middle-market operators. Senior practitioner delivery — the partner who sells the engagement is the one doing the work.
How is client confidentiality handled?+
All advisory engagements run under written confidentiality terms before any work begins. Platform interactions on jiesen.ai are educational and reference-grade — they do not constitute an advisory engagement and are not protected by engagement-level confidentiality. For sensitive work, contact Jiesen Li Advisory directly.
