You don’t need a banker to build a financial model!

One of the “must have” slides in a B2B start-up deck is the financial projections model. There is one untold universal truth about these models- they are myths (the second thing in common for this part of the presentation is that the CEO always starts it with “we have taken a conservative approach…”)

Now, if everyone knows that the model is off the beam- why waste time building on it? The answer is very simple. Actually, it’s not the answer rather the approach and the assumptions. This helps investors to authenticate  that you have considered dynamics like Unit Economics -the charge per seat .What will be the number of seats per customer? Business Strategy -Number of  customers  expected. What is the average deal size? Spending Characteristics-the cost of building a product. What is the sales and marketing plan? and that you made sure the business model works.


One of the biggest turnoffs is a financial model which shows the team just doesn’t understand the space. It is important to take guidelines and understand the scenarios that need to be avoided. Learn them now!!

Few mistakes that can pin you down, beware of them.

Hiring a banker to build your financial model

For an early stage company, building a financial model should be pretty simple. Since the model is inherently incorrect then there is really no need to over complicate it or present false accuracy. The problem is that this is exactly what your banker is likely to do to justify his fees / commission. It is better to take in that the model is still in progress and is intended more as a thought exercise than anything else. Even worse, when you outsource this to a banker you miss the key benefit of building a financial model – understanding the fundamentals of your business.

Not being connected to reality 

Here is the 3 year P&L I got from a company that is building a marketplace for Real Estate professionals to offer their services. If anyone has ever built a marketplace, they would know it takes a long time to generate revenue. Moreover, I don’t think that in the history of subscription model there has been a company that generated $60M in revenue and $37M in EBITDA in 3 years! One last thing here, if it costs you “just” $2M to generate significant profit- it probably means the barrier to entry is too low.


Combining different revenue models into one statement

There are very few successful companies that sell both perpetual license and subscription (a topic for another post). The difference between the two is huge from a business model perspective. Some companies that we see plan to do both (which is typically not a great sign). But to make things worse, some go further and combine both types of models into one P&L statement. Once combined, there is just nothing you can learn from the model

Significantly underestimating cost

Too many times we hear “this is the last round of financing” when the company is pretty early or in a space which is known to require a lot of capital. The truth is that for almost all early stage companies things take longer than expected and they don’t meet revenue plans. Making things worse is that most companies spend much more than they originally anticipated. Moreover, even if everything goes extremely well then in most cases you will want to raise more money to double down on the opportunity ahead before competition catches up.

Significantly overestimating cost

You might ask yourself why would anyone want to overestimate cost. The quick answer is typically to justify a larger round which is another way of increasing valuation. When you try to estimate cost for the following year ask yourself how many sales reps do you have today and how many can you really hire in a year. Same question goes for developers, marketing people, support reps etc. It takes time to find strong talent and it gets more difficult to do so at scale. So either you plan to lower the bar or you will just not be able to ramp up hiring as quickly as you think.

Instead of following the mediocre procedures build your models your own way. If done rightly, it will force you to think about key business questions long before you encounter them.
