Building Financial Clarity for Entrepreneurs
We started Hasterina because we saw too many talented business owners struggling with numbers when they should've been focused on growth. Our approach strips away complicated jargon and focuses on what actually matters for your business.
Why We Do This
Back in 2019, I spent three years working with established corporations. The systems were solid, but everything felt disconnected from real business challenges. Entrepreneurs needed something different—practical guidance that fits their specific situation.
Singapore's business environment moves fast. You're dealing with supplier payments, employee salaries, tax obligations, and trying to plan for growth all at once. We built our methods around those actual pressures, not theoretical models from textbooks.
Our team works with you to create budgeting systems that make sense for your business stage. Whether you're just starting out or scaling operations, the fundamentals stay consistent: know where your money's going, understand your margins, and plan ahead without overcomplicating things.

How We Actually Help
Three areas where we focus our energy, based on what entrepreneurs tell us they need most
Cash Flow Mapping
We help you see exactly where money enters and exits your business. Most entrepreneurs know their revenue, but tracking the timing and patterns of expenses? That's where things get tricky. We build simple tracking systems that show you the real picture.
Cost Structure Analysis
Understanding which expenses are fixed and which scale with growth changes everything. We break down your cost structure so you can make informed decisions about pricing, hiring, and investment. No guesswork—just clear data about what drives your profitability.
Growth Planning
Scaling a business requires different financial thinking. We work with you to model various growth scenarios—hiring another team member, expanding your product line, or entering new markets. The goal is to understand the financial implications before you commit resources.



Real Experience from Real Businesses
The methods we teach come from working alongside entrepreneurs who face actual financial challenges every day. We've refined our approach based on feedback from dozens of business owners across different industries in Singapore.
You won't find generic advice here. Every business has unique cash flow patterns, different cost structures, and specific growth targets. Our framework adapts to your situation rather than forcing you into someone else's template.

Working with Willem changed how I think about business finances. Instead of avoiding the numbers, I now check them weekly. The budgeting system he helped me build takes about 20 minutes to update and shows me exactly where I stand. It's straightforward, which is what I needed.
Our office is located at 1 Jln Kuala, Singapore 239639. We typically work with entrepreneurs for 4-6 months, helping you build systems that continue working long after our engagement ends.
