Great discussion with 30+ CFOs and Finance Directors from CAC40 companies & top startups in France, yesterday at the Google "CFO Breakfast". Key points:

(1) The ultimate objective = Profitable growth: profit and growth are equally important to drive value creation and build a sustainable business. The art is in finding the right trade-off between the two (the level of investment which hits the "sweetspot", the right balance btw direct profit generation and growth). Companies who maintain a long term, growth oriented mindset even in times of crisis get their heads out faster and end up generating higher TRS.

(2) Return of Google investment is very predictable: we have built advertiser-specific spend elasticity models which can tell clients what's the expected uplift in volume (clicks, transactions, revenue) at different levels of investment. By combining that with a simple profitability model you get to project profits, and have in front of you the trade-off volume / profit at different investment levels.

(3) The decision framework is not that complex: you need (i) Media Mix Model to help you understand the relative contribution of different channels to the generation of incremental sales, and give a directional answer for channel allocation. In the absence of MMM, at a minimum calculate the brand uplift effect that you observe - eg boost in brand queries from a YT or TV campaign. (ii) channel elasticity curve like described above, to help you understand the relative size of opportunity in each channel, and prioritize the ones which show most headroom; (iii) incrementality tests critical to confirm that changes you make in channel allocation bring the expected results.

(4) Test-and-learn approach: "don't let perfect get in the way of good". The above framework will give you a directionally correct answer, based on which you can take incremental moves in one direction or another. Measure results, then adapt / add complexity later (eg it's easy to adapt this net profit model to one that looks at LTV and LTV / CAC). Important to set testing budget aside and have flexibility in channel allocation throughout the year.

(5) Finance owns investment - Marketing spend is investment: far too often Finance remit is limited to cost control and Marketing ends up being treated as a cost line rather than what it really is, an investment with attached ROI. Finance should try to understand how Marketing channels work, get into the details of MMM study design, incrementality calculation, help with profitability models that Marketing can use to build the investment case. Getting Marketing and Finance to speak the same language is critical to achieving profitable growth - and Finance needs to take the first step.

notes to self: we're so lucky at Google to be able to dedicate so much mindspace to growth topics, it's not a given everywhere. And wearing a suit is acceptable every now and then
