Building Financial Models That Actually Work

We started quantheliora in 2019 because we kept seeing the same problem. Businesses would spend months building financial models that looked impressive in presentations but fell apart when it came time to make actual decisions. The spreadsheets were there, sure — but the logic underneath was fragile, assumptions were buried three tabs deep, and nobody could explain what happened when you changed a key variable.

So we took a different approach. Instead of building models that impress investors for five minutes, we build frameworks that finance teams can actually use every day. Models that adapt when your business changes. Systems that make your assumptions visible and testable.

What We Mean by Financial Model Building

When we say financial model building, we're not talking about templates you download and fill in. We mean creating custom analytical frameworks that reflect how your specific business actually generates revenue and incurs costs.

A property development firm needs models that handle staged construction timelines and presales commitments. A SaaS company needs cohort analysis and churn modeling built into their forecasts. A manufacturing business needs working capital cycles that reflect actual production lead times.

The models we build incorporate your operational reality — not generic formulas from a textbook. And when market conditions change or you pivot strategy, the model adapts because the structure was designed with flexibility from the start.

How We Build Models That Last

Structure First

Before any formulas get written, we map out your business drivers and how they connect. Revenue doesn't just appear — it comes from specific activities with timing and dependencies. We diagram those relationships first, then build the model to reflect that structure. This means when something changes in your business, you know exactly where to adjust the model.

Transparent Assumptions

Hidden assumptions are how financial models break. We put every assumption on a dedicated inputs sheet with clear labels, reasonable ranges, and notes about where the numbers came from. Your finance team shouldn't need to hunt through nested IF statements to understand why revenue grew 23% in Q3. The logic should be right there, documented and testable.

Scenario Planning Built In

Markets shift, products launch late, key customers churn — your model needs to handle reality, not just the base case. We build scenario switching directly into the framework so you can test optimistic and conservative cases without rebuilding formulas. You get one model that handles multiple futures, not three separate spreadsheets that diverge over time.

Linnea Valtonen

Lead Financial Architect

Linnea spent seven years in corporate finance at mid-sized tech companies before joining quantheliora in early 2021. She got tired of watching CFOs make strategic decisions based on models that nobody really understood — including the analysts who built them.

Her background in both accounting and software development gives her an unusual perspective on model design. She thinks about financial models the way developers think about code architecture: modular, documented, maintainable. When she's not building forecasting frameworks, she's usually hiking the trails around Canberra or trying to convince her team that tabs are better than spaces (a losing battle, apparently).
