As an early stage company your resources are limited and taking advantage of various programs that support startup ecosystems can significantly extend your runway.
They have various restrictions so you might not fit to all of them. Some require that you've raised funds before.
Here are programs from 5 big infrastructure providers:
- Google Cloud Startup program - probably the easiest to get as long as you raised money
- Digital Ocean Hatch - requires association with one of their partners (VC, accelerator, startup program etc)
- Linode Rise Startup
- Microsoft for startups - some limitation on bitcoin businesses
- AWS Activate - requires a VC that is part of Activate program or part of accelerator (get your investors to sign up if they aren't yet, its free and easy)
- Alibaba Cloud Startup Catalyst - for funded startups
