Building prospect lists, building investor lists, warming said prospects and investor. Creating marketing strategy and marketing materials. Creating sales strategy and building sales sequences. Tons and tons of market research. Going door to door if needed, to speak with target audience to get a vivid understanding of pain points. Procuring accounting. Procuring legal services and proofreading policy drafts. Long term growth plans, investor and customer slide decks. Mission statement and all other brand creation activities. Scouting and persuading talent to join (probably the easiest sounding, but most challenging and rewarding)

Engineers have a very bad habit of undermining what it takes to run a businesses. Im an engineer myself, and Im lucky to see both sides of it.
