Once you’ve hacked your way to a few quick wins, you’ll likely discover that the analytics and experimentation tools you’re using won’t suit your long term goals around deep analysis and rapid experimentation. Growth Teams tend to win by creating compound interest, meaning lots of small/medium wins rather than a few big ones. This means you need to optimize your team for high experiment throughput, and nothing will slow you down more than weak data/experimentation tools. Every company’s situation is different, and the best tools change every quarter, so trying to recommend an exact toolset isn’t helpful. That said, make sure you reach out to people that have done this well recently and bring the best-in-class tools in-house.
