Judgement where finance, tax and cross-border risk converge.
Thyor is a principal-led advisory firm for private businesses, owners, investors and internationally mobile families. We work where finance, tax, transactions and cross-border risk converge — from building the CFO function and repairing liquidity to structuring international tax, evaluating private-market transactions and underwriting expansion across jurisdictions.

The firm
A specialist advisory model built around the decision.
The firm is deliberately built around senior practitioners rather than a leverage pyramid. Engagement teams are small, domain-specific and accountable to the decision in front of the client. Every professional deployed to a mandate brings at least a decade of relevant industry or subject-matter experience.
That model allows Thyor to work across an unusually wide range of private-company situations without pretending every client needs the same institutional machinery. A family-owned operating business at $5 million of revenue, a sponsor-backed platform at $300 million and an institutional investor evaluating a multi-billion-dollar cross-border programme face different governance and information requirements. The underlying discipline is the same: establish the facts, model the consequences and make the options explicit.
Where Thyor is strongest
Three lead capabilities, supported by an integrated advisory platform.
These are the areas most likely to bring clients into the firm. The broader practices exist because the underlying decisions rarely stay inside one service line.

CFO & strategic finance
Fractional and interim CFO leadership, FP&A, liquidity, finance transformation and board-grade decision support for businesses whose complexity has outgrown their finance infrastructure.

Tax advisory & compliance

Where we advise

When clients call us
Most mandates begin with a situation, not a service line.
If one of these is recognisable, the useful first step is usually to define the decision and what happens if it is delayed.
- 01
The finance function has stopped keeping up
Reporting, forecasting and cash visibility no longer match the scale or complexity of the business.
- 02
A capital or ownership event is approaching
A raise, acquisition, sale, recapitalisation or refinancing requires numbers and structure that will survive external scrutiny.
- 03
Tax exposure is moving faster than compliance
New states, jurisdictions, entities or owner circumstances are creating obligations that cannot be handled as an annual filing exercise.
- 04
Growth has crossed a border
Market entry now requires an integrated view of tax, capital, country risk, operating structure and the economics of the local footprint.
- 05
An investor needs an independent operating view
The underwrite, portfolio reporting or value-creation plan needs analysis from people who can move between the model and the business.
- 06
Liquidity needs control quickly
Cash headroom, covenants or stakeholder confidence require a forecast that reconciles to reality and a sequenced plan management can execute.
- 07
A private client is approaching a relocation or liquidity event
US and international tax, ownership and timing need to be resolved before the transaction or move constrains the available choices.
- 08
A board faces a decision with geopolitical consequences
Policy, sanctions, industrial strategy, currency or country exposure needs to be translated into financial scenarios rather than commentary.

A cross-border practice
Global capability expressed through the work, not a map of decorative offices.
Thyor is remote-first, with operating hubs in McLean, Zurich, Singapore and Bangkok and senior advisers deploying on site when the economics and sensitivity of a mandate justify it. Other markets are served through remote work, project travel and established jurisdiction-specific specialists.
The firm has worked across North America, Western and Eastern Europe, the Gulf, Central and South Asia, Southeast and East Asia, Australia and selected Latin American markets. Geo-macro and government-adjacent work is often subject to strict confidentiality, so the public website deliberately describes the decision framework rather than the client or underlying programme.
Market entry & expansion
Entry economics, entity and tax architecture, country risk and operating design for a new jurisdiction.
Cross-border transactions
Private acquisitions, disposals, valuations and capital decisions spanning legal and tax systems.
International private client matters
US expatriate tax, relocation, ownership and liquidity events for families whose lives and assets cross residence lines.
Geo-macro & capital allocation
Policy and country scenarios translated into cash flow, valuation, supply-chain and portfolio consequences.

The thirteen-week cash flow: the discipline that buys time
When liquidity matters, nothing else a finance function produces carries the same weight. A rolling thirteen-week cash flow — honestly built and rigorously maintained — changes what management, lenders and owners can do next.

Selling a business: the two years before the process
Most of what decides the outcome of a sale is settled long before the information memorandum is written. The owners who transact well are the ones who treated the final two years as part of the transaction.

Cross-border expansion is an investment decision, not a market decision
Companies enter new geographies for market reasons and fail for financial ones. The expansions that work are the ones that were underwritten as investments before anyone booked a flight.

FP&A after founder-led growth: build the decision system before the finance department
The useful FP&A function is not a larger budget spreadsheet. It is a small number of reconciled models, definitions and meetings that change operating decisions.

Geo-macro risk belongs inside the investment model
Country risk is useful only when it changes assumptions, capital gates, valuation or the decision to proceed.
