Having reviewed hundreds of financial models across more than fifteen industries, I’ve identified five most common mistakes entrepreneurs make when creating their financials. In this article and the corresponding video, we discuss each of these mistakes in more detail so that you can learn how to model your company correctly and get funded faster.

Mistake #1: Hardcoding financial projections
Hardcoding expected financial performance is the go-to strategy for many founders with no financial experience, especially when it comes to projecting sales. This approach is incorrect because 1) you do not know where the data is coming from and this makes it impossible to validate the numbers and 2) you can’t see the financial impact of changes in your assumptions.
Only the underlying factors that impact revenues and costs, also called revenue and cost assumptions, should be hardcoded. These assumptions come from your strategy and industry standards. Please see our blog post on how to create credible financial model assumptions for more info.

Mistake #2: Using random number generation to create projections
Your financial model is a quantitative representation of your strategy and a tool to measure its effectiveness. Your financial goals, specifically sales goals, are not random and thus should not be randomly generated.
Instead, you should figure out what your goals are, think through how you are going to achieve them, and formulate metrics that will measure the effectiveness of your strategy.
-
Mistake #3: Not having a financial summary
A financial summary is a snapshot of your financial model that highlights all key assumptions and results. Usually a financial model has many parts and it can take an investor a lot of time to decipher the key findings and the underlying logic. Thus, to save investors time and to make their due diligence process easier, I recommend that you always have a financial summary. In addition, it will help you determine what to focus on when you present your financials.
-
Mistake #4: Calculating funding needs without using your financial model
Your funding needs must come directly from your financial model. In many cases, founders determine their financial needs based on the perception of what they need, rather than a robust financial plan. This is wrong and leads to a lot of unnecessary questioning by investors.
-
Mistake #5: Improperly aggregating your financial data into the three financial statements
There are three main financial statements: Income Statement, Balance Sheet, and Cash Flow Statement, and it’s important to create all of them properly. Many entrepreneurs know how to put together an Income Statement that shows how much profit they project to make, but are confused about how to generate the other two statements. The Balance Sheet is a snapshot of the company’s financial position and the Cash Flow Statement details how the cash is used between the operating, investing, and financing activities. It is critical to have your financial model built properly so that investors take you seriously and you have a complete picture of your business from the financial point of view.

“What I appreciated most about this program was the opportunity to stop during the work day and have an opportunity to reflect. In addition to having access to pre- and post-session materials that were profoundly useful (which I will undoubtedly go back to), being asked to stop, breathe, and process was a gift that carried throughout the day, week, and program. I recommend this program to any female founder or business owner in the midst of building her business.”
“Atending the Power Up Coaching pilot has been an absolute game-changer for me. Victoria and Hamp’s expertise, passion, unwavering support and genuine commitment to empowering women in the entrepreneurial space were evident in every session.

Sharing stories, challenges, and dreams with fellow entrepreneurs created a bond that transcended mere networking—it felt like finding a tribe where I truly belonged. It has equipped me with invaluable skills, insights, and a network of like-minded individuals who continue to inspire and support me on my entrepreneurial journey.

From the first session, the small group size allowed a safe, supportive environment to openly discuss challenges.

“Victoria provided me with great knowledge for the financial projection and reviewed my pitch deck where she provided me with great pointers. She definitely is somebody I count as my inner circle of advisors and recommend her as the go to person for any start up.”

“I have the greatest appreciation for Victoria’s contribution in analyzing financial trends and developing the monetization strategies for my business. She is not only an experienced financial analyst, but she is also very creative and gave my business many important suggestions. I felt comfortable and willing to reveal information easily, which helped make the valuation process easier. Victoria can see the big picture almost immediately, and at the same time she is a stickler for details. These attributes make her a perfect financial advisor and mentor for entrepreneurs. Further, Victoria, once given a task, is completely dedicated to it. She has a keen ability to process and synthesize information and make the right decisions, and she comes with the highest recommendation.”

I couldn’t recommend her enough as a resource for any entrepreneur looking to build out a financial model, financial roadmap and/or valuation of their enterprise.”
“Victoria Yampolsky came highly recommended by a colleague of mine and I’ve been fortunate to work with her! She completed the valuation and the financial model for our startup, EnergyPoints. Her unique framework for modeling early-stage ventures allowed us to refine our business plan and use strategy and industry standards to credibly formulate assumptions. Victoria is a Columbia Business School grad and CFA, and her company, The Startup Station, has done 100s of valuations and has an impressive track record. She presented her valuation to two national banks with our accountant, and in both scenarios, she was praised by the level of detail that went into her extensive valuation. I can’t recommend her highly enough!”
“Victoria was a key advisor for Predictive People – as an early stage startup we had tons of questions and we needed professional guidance to sort them out. I am really glad we had her by our side to solve them all, ending with a solid business plan and financial projections. I can’t recommend her more, she’s professional, fast, empathetic, and incredibly smart, a true partner for any startup.”
“Victoria is trustworthy, knowledgeable and customer-focused startup strategic CFO. I’ve been impressed since day 1 with the responsiveness, thoroughness and overall professionalism of Victoria. According to the traditional scenario of almost all early stage startups, the founders are involved in all processes of the company formation. So I am no exception without having a financial education, without professional Excel skills – I nevertheless decided to build a financial model on our own. Honestly, it seemed impossible. But in the end, we did it in a total of 3 weeks. I want to express my deepest gratitude for professionalism and incredible talent to motivate all of our team members. Victoria has a unique ability to get into the essence of the business very quickly, to think very flexibly and innovatively – which is very important for our startup.
“I was a student and client of Victoria through The Startup Station and cannot highlight enough how helpful the process was for our company in reaching our first funding milestone and personally for me. Victoria is a fantastic teacher and recommend her financial modelling courses to anyone. We also worked one to one to refine our company model/financial roadmap and Im proud of my newly developed, ninja-level Excel skills. Paraphrasing from someone famous “Clarity trumps confidence any day of the week” and it’s what I feel from working with Victoria.”
“Building a financial model with Victoria and The Start Up Station for a mutual client was an illuminating experience!
“Victoria is a rare find in the startup world. She’s brilliant with startup financial strategies and has this no-nonsense work ethic that proves to deliver results. Victoria worked with a participant of 2020 Startups, a startup founder, and within a couple of months the founder raised capital. Victoria has done several workshops and speaking engagements at 2020 Startups and is always insightful and held in the highest regard by the audience.”
“Victoria and The Startup Station Team were absolute game-changers for Ovaterra. Victoria served as my right-hand CFO through fundraising, M&A, liquidity crises and more — always guiding the ship with calm, detail-oriented and strategic advice. I would recommend her and her team to any Founder or executive who needs a strategic, fractional CFO to guide your business to the next level.”
“Victoria, we raised $1.4M! It’s finally 
“Victoria is one of the smartest, and most talented financial analysts out there. She has created the financial models for 2 of my companies, to which we have raised over $20M using her financials and valuation reports. She is very professional and always makes you prove the assumptions:) She will always be a vital part to my businesses.”
“In business, and especially with startups, getting to a place of clarity around the business and financial models can be challenging even for the most experienced professional. Victoria brings the right mix of business and financial know-how and quickly understands the moving pieces. As such, she’s able to provide an excellent product, a deeper sense of understanding about the project based on its’ needs, and a sense of calm and assurance that the challenges faced will be dealt with in a way that drives growth.”
“I had the pleasure of working closely with Victoria as fractional CFO of our startup. Her expertise in business and financial modeling is truly exceptional. Victoria played a pivotal role in helping our company think through every aspect of our business, and her ability to create a comprehensive model was nothing short of impressive. She not only provided a clear plan for our future but also identified areas where we could improve and grow.
