Building Financial Clarity Through Education
We started prologicstream in 2019 because the gap between academic finance theory and practical modeling work felt too wide.
Most finance graduates we met could explain complex theories but struggled when opening Excel to build an actual model. That disconnect bothered us. So we created programs focused on hands-on skills—the kind you actually use when building cash flow projections or valuation models at work. Our approach comes from years of building models for real businesses and noticing what separates theory from practice.
Practical Over Perfect
We don't teach you to build the perfect model. We teach you to build models that work under deadline pressure. That means knowing which shortcuts are safe and which assumptions matter most. Real financial modeling involves judgment calls and trade-offs—not just formulas.
Context Matters
A retail cash flow model looks different from a SaaS revenue forecast. We teach across industries because that's how you develop adaptable skills. You'll see how the same principles apply differently depending on business models, revenue structures, and cash conversion cycles.
Questions Welcome
Financial modeling involves lots of "why" questions. Why use this discount rate? Why structure the model this way? We encourage those questions because they show you're thinking critically. Our instructors have built models for mining operations, retail chains, and tech startups—we've asked those questions ourselves.
Who Teaches These Programs
Our lead instructor spent over a decade building financial models for investment analysis and business planning. He's seen what works in practice and what causes problems down the line.
Corbin Threlkeld
Program Director & Lead Instructor
Corbin worked in corporate finance for mining companies and retail businesses before starting to teach. He built his first three-statement model in 2009 and has been refining his approach ever since. What he enjoys most is showing students how to spot the assumptions that actually drive a model's output—the 20% of inputs that create 80% of the variance. Outside of teaching, he consults with small businesses on financial planning and still builds custom models for specific projects.
Based in North Geelong
We run our programs from North Geelong, serving students across Victoria and beyond through both in-person workshops and online courses. The Australian business environment gives us plenty of case studies—from agricultural businesses managing seasonal cash flows to manufacturers dealing with supply chain complexity.

What Drives Our Approach
Transparency in Assumptions
Every financial model rests on assumptions. We teach students to document them clearly and test how sensitive their outputs are to changes. A model with hidden assumptions creates problems later when someone needs to update or audit it.
Continuous Improvement
Financial modeling practices evolve as tools and business environments change. We update our curriculum based on what we're seeing in current projects and feedback from former students now working in the field. What worked well in 2020 might need adjustment by 2025.
Real Business Context
Our examples come from actual business situations we've encountered—anonymized and simplified for teaching purposes, but rooted in reality. You'll work with revenue patterns that make sense and cost structures that reflect how businesses actually operate.
Long-Term Skill Development
We're not interested in teaching quick tricks that become obsolete. The programs focus on foundational skills that adapt as your career progresses—whether you're building models for investment analysis, corporate planning, or business valuation down the line.
