I've worked at 3 different startups, which were all unique.<p>The first found good product/market fit and, though not profitable, had a solid customer base and a good technology. Founders were also knowledgable and well-connected in the space. On the negative side, the CEO lacked experience and was related to the principal of our main funder, and company debt load steadily grew over time as hiring and expansion outpaced growth. The dotcom crash also happened at this time. The company eventually exited (acquisition) with C-level getting retention packages from the acquiring company, and with shares worth zero dollars.<p>The second startup was the opposite. It was small and scrappy and had only taken $20k in seed money before becoming self-sustaining. We only grew as fast as we could afford to and never took any additional funding. While this was great from a financial perspective, it meant zero to no growth after several years. The founder wasn't looking for an exit, and enjoyed a nice income from the business. It's still going after 18 years.<p>The last one was also interesting. I rose to executive level there. We struggled with a long history (a few previous pivots before I joined) and funding that was on an ongoing, monthly basis. There was no cash pile to manage or be strategic about. We also had some trouble finding product market fit, but eventually found it, but lack of ability to market effectively, which greatly limited growth. The CEO also had a vision for the company that differed from the rest of the executive team, so when we eventually identified and pursued a strategy that led to our eventual acquisition, we had to half-ass it (i.e. couldn't fully reorient the company on it), which ultimately led to a reduced valuation when we were acquired. Again, stock was worth zero, but the main investor gave everyone in the company a cash bonus based on longevity and role, plus compensation from the acquiring company meant those remaining (everyone but sales and marketing) essentially got 20-30% raises. (that company's stock tripled after the acquisition, so everyone effectively got 50-100+% more out of the deal).<p>What did I learn from all of that? It's important to go into a startup with goals in mind. I wanted to learn, play a big role in a company, build cool stuff, and work with cool people. The nature of startups is often that if you want to do something, you can do it, because there's no one else. I learned an amazing amount in my day. My goal wasn't to get rich, so I viewed anything positive as a bonus, really. That said, things go better when the culture is one of working collaboratively with each other, vs. being adversarial. There should be a strong vision about goals for the company (lifestyle, exit, etc) and the product. Most of all, learn all you can about all of the things, and you'll be well set up for future experiences.
