Your infrastructure bill
is a margin line
For a product company, cloud spend is not an IT cost — it is cost of goods sold, and it shows up in every valuation conversation. That reframing changes which engineering work is worth doing.
What product engineering leaders bring us
Gross margin moving the wrong way
Revenue grows, infrastructure grows faster, and nobody can say which customers or features are responsible because everything shares one account and one bill.
Enterprise deals stalling in security review
The deal is agreed and then spends three months in a questionnaire, because tenant isolation and control evidence were never designed to be explained to someone else's auditor.
A noisy-neighbour problem you cannot price
One large tenant degrades everyone else's experience, and the pricing model has no mechanism to reflect the cost that tenant actually imposes.
What we do for software companies
Architecture decisions here are commercial decisions. We treat them that way.
Multi-tenancy and isolation
Pool, bridge or silo per tier — chosen deliberately, with the isolation boundary you can describe to an enterprise security reviewer in one diagram.
- Tenant isolation strategy per customer tier
- Data partitioning and access enforcement
- Onboarding and offboarding as automated flows
Gross-margin engineering
Cost attributed per tenant, per feature and per plan, so pricing, packaging and platform investment are argued from the same numbers.
- Cost per tenant and per plan
- Feature-level cost attribution
- Margin modelling for new pricing
Enterprise readiness
SOC 2 and ISO 27001 groundwork on AWS, plus the artefacts that shorten security review: architecture diagrams, control evidence and answers that do not require an engineer each time.
- Control implementation and evidence automation
- Security questionnaire answer library
- Penetration test remediation support
Scale engineering
Load isolation, rate limiting, async decomposition and caching so one tenant's Tuesday does not become everyone's incident.
- Per-tenant quotas and rate limits
- Async decomposition of heavy paths
- Capacity modelling tied to sales forecast
What your customers' auditors will ask
In SaaS the compliance pressure usually arrives through your customers rather than a regulator — which makes it a revenue problem.
SOC 2 / ISO 27001
The two most commonly requested attestations in Australian enterprise procurement, with evidence generated from your pipelines.
Privacy Act & APPs
Your obligations as a processor, and the contractual commitments you make to customers about their data.
Data residency commitments
Where you promise data stays, enforced architecturally rather than by policy alone.
What software companies ask first
The cost model is not — it is cheap to build early and expensive to retrofit. Full multi-tenancy re-architecture usually is premature before you have enterprise demand pulling for it.
That is the normal shape. An embedded squad works inside your cadence and your codebase, with your engineers on the same tickets. We are not trying to become your platform team.
We extend it. Rewriting working Terraform to our house style would burn your budget on something that produces no customer value.
No — we are not an audit firm. We do the engineering and evidence work that makes the audit straightforward, and we work alongside whichever auditor you select.
Start with the number your board will ask about
Infrastructure cost per tenant, per plan and per feature. Six weeks to build the model, and it usually changes at least one commercial decision.
