Ask HN: Do provisional patents matter for early-stage startups?

I am a solo founder building in AI B2B infra.

I am filing provisional patents on some core technical approaches so I can share more openly with early design partners and investors.

Curious from folks who have raised Pre-Seed/Seed or worked with early-stage companies: - Do provisionals meaningfully help in fundraising or partnerships? - Or were they mostly noise until later rounds / real traction?

I am trying to calibrate how much time/energy to put into IP vs just shipping + user traction at this stage.

Would love to hear real world experiences.
