Solution · Foundation Zero / Cloud FinOps platform / Serverless · live

Every cloud dollar,
accounted for
every night.

Foundation Zero is a serverless FinOps platform that processes thousands of cost-optimization events nightly across multi-account AWS estates — turning billing noise into ranked, owned, actionable savings.

— The problem

Cloud spend grows faster than anyone can track.

Between Reserved Instances, Savings Plans, right-sizing, and resources nobody remembers launching, cloud cost management has become impossibly complex. Reaching even 95% optimization is out of reach for most teams.

The data is there — Cost and Usage Reports, resource metadata, usage patterns — but it's spread across dozens of accounts and millions of line items. By the time someone analyses it, the bill has already landed.

Foundation Zero closes that gap. It processes the whole estate every night, surfaces ranked optimization opportunities within seconds, and routes each one to an owner with a full audit trail — so savings actually get actioned.

// 01 — Ingest & normalize

Every account's billing data, ingested nightly.

Foundation Zero pulls Cost and Usage Reports, resource inventories, and Savings Plan & RI utilization from across your AWS organisation — normalizing millions of line items into a queryable model.

EventBridge schedules the run; Lambda fans out per account; S3 holds the partitioned data lake with lifecycle archival built in.

  • Cost & Usage Reports, resource metadata, usage patterns
  • Multi-account, multi-region, single organisation view
  • Partitioned in S3 — lifecycle-archived to control storage cost

// 02 — Detect & rank

Billing noise becomes ranked opportunities.

A fleet of focused Lambda functions analyses the normalized data — Reserved Instance gaps, idle resources, right-sizing, Savings Plan commitments, storage waste — and scores every opportunity by impact.

Each recommendation carries the accounts, resources, and dollar impact behind it. Nothing is surfaced without the evidence to back it.

  • Reserved Instance & Savings Plan coverage
  • Idle & orphaned resource detection
  • Right-sizing across compute, database, and storage

// 03 — Assign & track to closure

From detected to realized savings.

Every recommendation can be assigned to a team member with a full audit trail. Foundation Zero tracks it from detection through action to verified, realized savings — measured back against the next night's Cost and Usage Report.

No spreadsheet hand-offs. No savings that look good in a deck but never land in the bill.

// 04 — Serverless architecture

Fully serverless, scales to any estate.

Foundation Zero runs entirely on managed AWS services — no servers to babysit. Lambda scales from a single account to hundreds simultaneously; EventBridge orchestrates the nightly run; SQS buffers the work; RDS PostgreSQL aggregates results behind RDS Proxy.

Costs track usage. Quiet periods cost almost nothing; peak nights scale out automatically — the platform practises the cost efficiency it preaches.

// 05 — Security & multi-tenancy

Multi-tenant isolation you can prove.

Billing data is sensitive. Foundation Zero enforces complete separation between organisations with AWS Cognito user pools, validates every API request against tenant context, and reads customer billing through short-lived STS credentials.

  • Per-tenant isolation with AWS Cognito user pools
  • Every Lambda assumes a least-privilege IAM role
  • Cross-account billing read via short-lived STS credentials
  • No long-term customer credentials ever stored

Every interpretation traces to a source line item
Cross-account reads use temporary STS credentials

— Where Foundation Zero fits

Built for estates where the bill outgrew the spreadsheet.

Foundation Zero is for teams running real money through AWS — multiple accounts, variable workloads, and a cost surface no one can eyeball anymore.

// 01

Multi-account enterprises

Hundreds of accounts under one organisation, analysed nightly as a single estate — with ranked savings rolled up and broken down by team, application, and account.

Org-wide · rolled up
// 02

Managed service providers

Per-client cost visibility with complete tenant isolation. Show every customer their own ranked optimization backlog — without their data ever touching another tenant's.

Multi-tenant · isolated
// 03

Scaling startups

Catch waste before it compounds. Idle resources, over-provisioned databases, and missed commitments surfaced the morning after they appear — not at the quarterly bill review.

// 04

Platform & FinOps teams

A ranked backlog of savings, each with an owner and a dollar value. Track every opportunity from detection to verified, realized savings against the bill.

Owned · tracked to closure
// 05

Regulated estates

Audit-ready cost governance. Source line items retained, interpretations traceable, and a full processing log — built to satisfy a finance or security review.

// 06

Cost-out programs

Board-level savings targets, broken into accountable line items and tracked to closure — so the number on the slide is the number that lands in the bill.
