Or generally how is the job scene after startup failure.
I have friends who started a startup, got VC money, and ultimately shut it down after 2-3 years. They didn't have any issue getting another job as they had a product to show and they worked with a standard team. It was essentially a 'business that failed' and they were able to show the successes they did have (fundraising/launching/hiring/etc).
I have friends who tried consulting/solo startup and gave up after a year of no traction. They had a harder time getting a job afterwards because people felt they were just going to leave after they got another idea for a startup. "Less likely to put up with work politics" or they felt they "just took a year off" because they didn't have much to show for it.
I've started startups/businesses as side projects and I've found that it has only helped me. Most people are curious about them, gives me something to talk about, and I get to discuss pain points and things I've learned. But, they don't see it as a threat as I present it as a way to "learn" and keep my skills up to date.
If you work on your own startup, and eventually shut it down, in SV at least is not seen as an issue and you'll have many opportunities. It all goes down to what you achieved in term of product and team.
If you run your own project for 2 months, you're not much better than before. If you grow a team even of 3-5 people, maybe raise some money, have a compelling story about your product, and hustle for a few years, that's a completely different story.
Best of luck.
