Ask HN: How did you make money while working on a pre-revenue startup?

To give you some background, I’m a product leader based in Montreal with over 10 years of experience in the tech industry, working with companies of various sizes. Recently, I faced a layoff and, as the primary breadwinner for my family, it’s a critical situation since they rely on my income. I’ve managed to save enough to buy us some time until next year while I explore a new venture.

Since then, I’ve been working full-time on an idea. Although it's still in the early stages and hasn’t generated revenue yet, I’m starting to see some traction. Right now, I’m bootstrapping it on my own.

I’d love to tap into the collective wisdom of this community: what strategies do you use to support yourself financially while pursuing your idea? Do you recommend consulting, freelancing, a part-time job, or even something more out-of-the-box?

I’m looking for practical ideas that can generate income in the short term while allowing me to maintain momentum with my startup. Extra points if your side hustle ended up benefiting your main project in some way!

Would love to hear what worked (or didn’t) for you!

I appreciate any insights you can share. Thanks in advance!
