AWS foundations for an early-stage startup

Most early AWS problems are permissions and surprise bills, not scale. An early-stage review sets up the few things that are painful to change later: separate environments and accounts, least-privilege access, infrastructure as code and cost alerts, and checks that the product is ready for its first real traffic.

AWS re-architecture that cut cloud cost by about 30%

Cloud spend had grown without anyone owning it. One of our experts re-architected the AWS setup: consolidated serverless functions, optimized the database, scheduled non-production environments to shut down off-hours, and added observability. Outcome: cloud cost down about 30%.

Questions buyers ask

What should a pre-seed startup get right on AWS first?+
Separate accounts for production and everything else, no shared root credentials, infrastructure defined as code, backups that have been restored at least once, and budget alerts. These take days to set up and months to retrofit.
Is a technical review useful before fundraising?+
Yes. Investors increasingly ask technical questions early. A pre-raise review finds the obvious gaps in architecture, security and delivery so the answers are ready before the first diligence call.
What should a pre-seed startup get right on AWS first?+
Separate environments and accounts, least-privilege access, infrastructure defined as code, and cost alerts before traffic arrives. Most early AWS problems are permissions and surprise bills, not scale. A short review catches these in a day or two.

How it works

  1. Tell us what you need — the repo or system, the question, and the deadline.
  2. We match an expert from the network, with a second reviewer where it helps.
  3. Scoped work, contracted through Invental — review per pull request, a fixed-scope audit or architecture review, or ongoing capacity.
