Fractional CTO / Senior Advisory

Your Series A Deserves an Architect, Not a Gamble.

Most funded startups make their worst technical decisions in the 12 months after raising. Not from lack of effort — from lack of architecture. We fix that before it becomes a crisis.

You're in the right place if —

01

You raised the round but don't have a CTO yet.

02

Your developers are building — but no one is architecting.

03

You've hired engineers before you had a system.

04

Your investors are asking technical questions you can't answer.

05

You inherited a codebase you don't fully trust.

06

Your platform works — but you're afraid to touch it.

Scope of Engagement

What a Fractional CTO Actually Does Here

Not advice. Not slide decks. Operational technical leadership with defined deliverables and measurable outcomes.

Architecture Oversight

We design the system before you build it. Every major technical decision gets reviewed against your business model, your runway, and your scale trajectory.

Vendor & Hiring Guidance

We evaluate vendors, agencies, and engineers on your behalf. We know what good looks like — and what to walk away from.

Investor & Board Communication

We translate your technical state into language your board understands. Roadmaps, risk posture, and architecture decisions — presented with clarity and credibility.

Technical Debt Strategy

We identify what's slowing you down, prioritize what to fix first, and build a plan that doesn't require a full rewrite to execute.

Team Structure & Process

We help you hire right, structure your engineering org, and install the delivery practices that scale past your first 10 engineers.

Escalation Coverage

When something breaks or a critical decision lands at 2am, you have a senior technical mind in your corner — not a contractor waiting for a ticket.

Technical Provenance

Why All Stone Tech

The combination of Fortune 20 enterprise depth and startup-speed execution is rare. Most consultancies have one or the other.

Fortune 20 Depth

We led development of enterprise platforms managing multi-billion-dollar financial operations. We've seen what happens when architecture fails at scale — and we've built systems that didn't.

Startup-Speed Execution

We've rescued MVPs, rebuilt failing platforms, and delivered production-ready systems in weeks. We don't confuse rigor with slowness.

Diagnosis First

We don't accept "we need a React app" as a brief. We insist on understanding your actual problem before we prescribe a solution. This alone prevents most catastrophic builds.

No Vendor Lock-in

You own the repo. You own the infrastructure keys. We build systems you can operate independently — and hand off cleanly when the time comes.

Remote-First, Globally Available

Distributed-team native. All engagements run async-capable with structured check-ins. No physical presence required. Scheduling accommodates clients across multiple time zones.

Engagement Structure

How Engagements Are Structured

Every engagement begins with a clear diagnosis. No retainers sold before we understand what you actually need.

Start Here

System Integrity Assessment

A structured audit of your current architecture, infrastructure, and engineering practices. You get a prioritized remediation roadmap and a clear picture of your technical risk profile — before you hire, before you build, before you scale.

  • No ongoing commitment required

  • Scoped to your specific situation
  • Output: production-ready modernized platform with handoff documentation

Operating Protocol

"Amateurs look for frameworks. Professionals look for constraints."

Our engagement model is built on diagnosis before prescription. We don't accept technical requirements from clients — we accept symptoms. The distinction matters: most expensive failed builds start with a solution, not a problem. We insist on reversing that order.

Next Step

Start with a Conversation, Not a Contract.

A 30-minute strategy session costs nothing. It either confirms you don't need us yet — or it surfaces the exact problem we should solve first. Either outcome is valuable.
