Susan Su on how to approach growth as your startup raises each round

‘I firmly believe that every founder should try their hand at growth’

Your startup might rely on clever growth tactics to get off the ground, but you need more than spreadsheets if you want to turn viral spikes into a real business. You need a qualitative growth model to guide the strategy that you can use to tell your story to your team and investors.

Growth marketing expert Susan Su sat down with us at TechCrunch Early Stage: Marketing and Fundraising this month to share pointers for young companies that are trying to raise money after initial market traction. In the presentation below, she maps out a growth strategy from seed through Series A and B rounds and details how your milestones, budgets, investor updates and other measures change as you advance.

Throughout the process, “a qualitative model tells the story of growth that you can use at early stages and really all throughout your company life cycle,” she explains. “A quantitative model or quantitative growth accounting charts the numerical course for how you actually deliver against that narrative and becomes more relevant at later stages when you actually have real numbers.

Formerly a strategic growth adviser to companies at Sound Ventures, a growth marketing lead focused on startups at Stripe, and the first hire and head of growth at Reforge, Su just became a partner investing in climate tech for early-stage fund Toba Capital. She also writes a popular newsletter on climate investing and runs a six-week course for other investors on the topic.

Here’s more about growth, and how to talk about it with investors, from her presentation:

So here’s a sample qualitative growth model that I built for one of our portfolio companies with some modifications for anonymity. At the bottom, we have our linear inputs that form the foundation of awareness — in other words, traffic or leads that feed into our growth machine.

Once those leads come in, we have our acquisition loops, working to turn that non-repeatable spiky linear traffic (aka TechCrunch traffic, if you get so lucky as to be written up in TechCrunch) into scalable, repeatable acquisition. You cannot repeat the TechCrunch effect.

For this sample business, I happened to spec out five different acquisition loops — I was really ambitious. Many companies will struggle to identify this many. But the key to being able to scale is to have multiple viable acquisition loops, not just one single thing that works.
