Architecture and scale review for growing products
When the system that got you here will not get you there, you need a clear read on what holds, what breaks, and what to do first. Agents and specialists collect the evidence. I decide the priorities.
When you need this
Growth is real. The architecture is showing stress.
- Growth is real and the architecture is starting to show stress
- You are about to invest in a platform bet and want a senior second opinion
- Multi-tenant, reliability, or cost problems are eating the roadmap
- The team disagrees on the next shape of the system and needs a locked decision
- You want depth on architecture without a full capital diligence cycle
If capital is moving and you need investment-committee-grade diligence across tech and product, go to Diligence instead. If you need someone in the seat week after week, go to the fractional CTO retainer.
What we examine
Scoped to your stage and stack.
Not a generic audit checklist sold as strategy. Agents and specialists collect evidence from code and docs. I decide what matters for your growth path and lock a priority order.
- Core domain model and service boundaries
- Multi-tenancy, isolation, and data shape
- Scalability paths and likely break points
- Reliability, observability, and failure modes that matter commercially
- Delivery path: CI/CD, release risk, and how change actually ships
- Cost drivers tied to architecture choices
- Security and secrets posture where it intersects architecture (this is not a full security audit)
What you get
Findings, priorities, a walkthrough you can act on.
- A written findings pack: what is healthy, what to watch, what is critical
- Prioritised recommendations with business impact, not an endless list
- A live walkthrough so engineering and founders share the same picture
- A practical next-step sequence your team can execute
Commercial terms are fixed-fee after discovery. No invented price bands on this page.
How it works
Scope
Agree stage, stack, and the growth question you need answered.
Collect
Agents and specialists gather from code and docs.
Decide
I judge what matters and lock a priority order.
Walkthrough
Live session so founders and engineering share one picture.
Handoff
Your team executes, or we move into retainer if you want the seat.
Vs diligence / vs retainer
Pick the brief, not a bundled product.
Capital decision / raise readiness / IC-grade tech + product read
Focused architecture and scale judgement
This page
Ongoing seat: weekly or bi-weekly leadership
Install AI-first operating norms around leadership
Architecture review can stand alone. It can also precede a retainer when the first job is to lock the platform direction.
Proof
I have carried architecture through real scale pressure.
