France and the United States
Headquartered on either side of the Atlantic, targeting the other for expansion
About the partnership
Built for the complexity of crossing borders.
Most advisory firms handle one country well. We built something different — a single operational team spanning Paris and New York, engineered from the ground up for companies that need both sides handled simultaneously.

Our story
Two firms. One operating model.
Orbiss and Impulsa began working together in 2020, with a shared conviction that transatlantic expansion deserved better infrastructure than the market was offering — firms that were either too local to see both sides, or too large to move at the speed scale-ups require.
What started as coordination between two specialised firms evolved into a fully integrated model: shared processes, unified reporting, and a single point of contact regardless of which jurisdiction a client's question originates from.
Today that model serves scale-ups across tech, SaaS, biotech, retail, and beyond — companies that can't afford to lose time between their Paris CFO and their New York counsel.
Who we work withMultiple markets.
Multiple markets.
No gaps.
We work with a specific type of company — not defined by size alone, but by the complexity of what they're attempting. If the profile below fits, let's talk.
Series A to Series C
Or bootstrapped equivalents with $1M+ in anticipated French or US-sourced annual revenue
Tech, SaaS, biotech, retail, F&B, fashion
Any sector where the US and French market is a primary growth target, not a secondary consideration
10–200 employees
With a finance lead or CFO who needs a reliable international counterpart, not a generalist
When teams engage usWhen to
When to
call us.
Engagements rarely start in the abstract. They start with a specific event, deadline, or pressure point. These are the most common.
01
Setting up the first presence
First hire or entity setup underway, with no existing compliance infrastructure.
02
Preparing for a fundraising round
Clean, auditable financials required across both jurisdictions before due diligence begins.
03
Outgrowing a local accountant
Existing setup has outgrown a local accountant with no cross-border visibility.
04
Managing a foreign subsidiary
A cross-border subsidiary of a local parent needing statutory compliance managed end-to-end.
05
Structuring intercompany flows
Intercompany billing or transfer pricing exposure that hasn't been properly structured.
How we work
The infrastructure behind frictionless expansion.
One engagement, two jurisdictions
A single onboarding process, shared client records, and coordinated delivery across both teams — no handoff gaps, no duplicated admin.
Speed that fits your timeline
We move with your fundraising timelines, hiring decisions, and regulatory deadlines — not an auditor's calendar.
Consolidated financial visibility
Unified reporting across US GAAP, French GAAP, and IFRS standards — giving your finance team and investors a single source of truth.
Integrated into your stack
We integrate directly with the ERPs, finance tools, and accounting systems your team already uses — meeting you inside your existing workflow rather than forcing a migration.
Onboarding stays light, your data stays in one place, and your CFO keeps the dashboards they already trust.
In-market expertise
Teams physically embedded in Paris and New York — same time zones as your operators, same regulatory ground as your filings, no offshore handoffs in between.
When a French tax notice lands or a US deadline shifts, the person responding is in the same market as you.
From “compliance” to “operating model”
We don't stop at the statutory minimum. We treat finance, tax, and legal as a connected operating layer — so the way you're structured today supports the next round, the next hire, and the next market. Decisions made early stop becoming constraints later, and every layer of the stack is built to scale with you rather than be rebuilt around you.
