Many of the big web services companies that develop software use such as AWS, Mailchimp, Sendgrid et al work around this idea. A lot of people decided to build startups. Those started first servicing a handful of startups and were able to grow and sell to Fortune 100 companies.<p>In the Blockchain hype era for example building KYC tools, social media marketing consulting for Crypto or coinmarketcap and so on, as others have suggested would have worked well.<p>You will generally want to provide a service that people would pay for in order to build their "great scheme masterplan", meanwhile others will try to do as well and eat their market, becoming your customers as well. While they race to the bottom in pricing and become unicorns, you take their money and grow your business silently.<p>Instead of making a brewing company in a city where there is a lot of hype, consider owning stocks of the local water/wheat etc provider, because the beer hype will drive up prices of other things as when people compete, they take investment and try to grow fast in the promise of huge returns, meanwhile you sell those to everyone that bought the hype with less investment and if there is a champion on this battle, you can sell as well your business to the winner. Looks like a decent strategy if you ask me.<p>For now, to be honest, we are more like heading to recession so I would rather look into servicing people in debt or looking for ways to save money, avoid losing too much in the crisis and so on. More like selling wipers to the people who are crying in a time of crisis than shovels in a gold rush.
