Orbiss + Impulsa Take Their France–U.S. Collaboration Further

After six years working together, Orbiss and Impulsa are launching a dedicated partnership for companies building across both markets.

September 9, 2026New York & Paris

For the past six years, Orbiss and Impulsa have worked together to help companies navigate growth between France and the United States. Now, we’re taking that relationship a step further.

Our new partnership brings together Impulsa’s expertise in France with Orbiss’ specialization in U.S. expansion, giving companies operating across both markets a more connected approach to their tax, accounting and financial operations.

A French company opening a U.S. subsidiary—or an American company establishing itself in France—quickly encounters two different accounting standards, tax systems, payroll requirements and regulatory environments. Decisions made in one market can have direct consequences in the other.

In the U.S., Orbiss supports companies with entity setup and structuring, corporate and sales tax, U.S. GAAP accounting and reporting, payroll and benefits, and broader financial operations.

In France, Impulsa provides accounting and statutory compliance, tax and social filings, payroll and HR support, legal services, and financial and strategic advisory.

Across both markets, our teams can coordinate on areas including consolidated reporting, intercompany transactions, accounting-system integration, tax structuring, fundraising and audit preparation, and the financial management of foreign subsidiaries.

“When a company expands internationally, the French and U.S. sides of the business can’t be treated in isolation. We’ve worked with Orbiss since 2020 and know how valuable it is when the teams on both sides already understand each other and work together.”

— Grégoire Proust, Founding Partner at Impulsa

Since 2020, Orbiss and Impulsa have worked with more than 120 scale-upsnavigating France–U.S. growth and cross-border structuring. Those companies have collectively raised more than $2 billion in funding.

“These are exactly the issues we see when international companies begin scaling in the U.S. Working closely with Impulsa gives us a much clearer view of the broader business and helps us address cross-border questions earlier.”

— Yoann Brugiere, Co-Founder and Partner at Orbiss

The partnership is particularly focused on growing companies for which France and the U.S. are core markets, including businesses in technology, SaaS, biotech, retail and e-commerce, food and beverage, and fashion.

“For clients, the real value is continuity. They have specialists in each market who already know how to work together and understand the bigger picture.”

— Laurence Goleret Ruiz, Co-Founder and Partner at Orbiss

For Orbiss and Impulsa, this is the next chapter in a relationship that has been growing since 2020—and a stronger foundation for helping companies build on both sides of the Atlantic.
