About

Built by someone who has raised, advised and operated.

An entrepreneur and finance executive

Dori Fussmann is an entrepreneur and finance executive. He founded Rupert to research investors and run personalized outreach for founders raising capital. You approve the list and the messages before anything is sent, and the investor relationships stay yours. Rupert does not take a percentage of capital raised. The roles below are why that work is built around a real raise, not a generic list of names.

Fractional CFO

Fractional CFO roles include BlueMark, Translucent AI, Natrion, and Snout. He serves as Fractional CFO of BlueMark, an impact-investment intelligence platform. At Natrion he served as Fractional CFO during the latest fundraise, working across financial planning, investor materials, and close. At Snout he served as Fractional CFO on the company's $100M financing round. Operating finance is how a raise is planned, modeled, and explained to investors. Rupert's investor research starts from that same view of the company.

Fundraising and strategic finance

He is Fundraising & Strategic Finance Advisor to Ambi Robotics and Manatee. The work covers financial planning, fundraising advisory, and go-to-market strategy. Neither role is a Fractional CFO engagement. The distinction matters for outreach: the investor list and the message follow the mandate of the raise, and the role is named for the work it actually is.

Advisory

He is an Advisor to Sniffi in India and an Advisor to Swift Vets in Australia. These are advisory roles, not finance engagements. They are separate from the Fractional CFO work and from the investor outreach Rupert runs for clients.

Companies founded

He is the founder of Rupert and the founder of InMarketLab. He founded and led The Vets, a technology-enabled home veterinary care company that raised institutional capital and later merged with BetterVet. Building and financing a company is the other side of the table from the banking work: what an investor asks, and what a founder has to be ready to answer. That is the standard Rupert uses when it researches investors and writes outreach.

Investment banking

At Citi, Morgan Stanley, and Ion Pacific he advised technology and consumer companies on M&A, IPOs, and strategic financing. That is the judgment in Rupert's investor research: thesis fit, timing, and whether the story holds in a real conversation.

Mentoring founders

He mentors early-stage founders through Cornell Tech's Runway Startups Program and Yale's Tsai CITY, on fundraising, financial planning, business models, go-to-market, and positioning. The same questions show up in a Rupert campaign: who the raise is for, and what the outreach needs to say.

Education

Dori holds degrees in Accounting and Business Management (B.A.) and Law (LL.B.) from IDC Herzliya.
