Precision financial engineering for variable-income professionals — the operating system between revenue volatility and personal sovereignty.
You're a high-performer trapped in a low-security cycle. The invoices are larger than most paychecks, yet the bank account rarely feels settled.
A €14,000 month followed by a €3,200 month. You spend the good month as if every month were the good month, then enter the bad month already depleted.
128 days from first contact to cleared cash. For four months, you were a bank extending a working-capital loan to your client at zero interest.
A bill arrives for an amount you didn't anticipate, due in a timeframe you cannot meet, on income you've already spent. The tax authority always wins.
Revenue is real but volatile. Skills are scarce but unprotected. Freedom is hard-won but operationally fragile. You're one missed invoice from crisis.
Not a budgeting manual. Not a mindset manifesto. A precision financial operating system designed for the specific pathology of the solo professional.
The 90-Day Soloist Runway engineers a complete financial infrastructure: auditing, mapping, shielding, stratifying, pricing, automating, and maintaining.
Know exactly — to the euro — what your monthly survival cost is. No more estimates, no more 2 a.m. anxiety.
A buffer that absorbs revenue volatility and pays you a flat synthetic salary every month, regardless of inflow.
The money for every tax bill, already waiting in a separate account. Tax season becomes a non-event.
Three stratified tiers — Emergency Piston, Freedom Buffer, Strategic Growth Tank — totaling 12 months of sovereignty.
Stop billing hours. Start capturing 10–20% of the value you create. Same work, 6.7× the captured revenue.
12 prompts that turn any LLM into your 24/7 financial analyst. Spending audits, forecasts, decision stress-tests.
"I trimmed €436/month from ghost subscriptions in week one. By month three I had a three-month Emergency Piston. The 2 a.m. anxiety is gone."
"The Tax Shield alone is worth 100× the price. My last VAT payment was a transfer, not an emergency. I sleep now."
"Switched from €90/hour to value-based pricing on a €240k value project. Captured €24k for 60 hours of work. The book pays for itself."
