Startup CTO

Startup CTO services for founders in Canada and the US. Advisory strategy sessions through embedded technical leadership and MVP delivery — the right depth for your stage.

The technical co-founder you don't have to hire full-time.

Reyem Tech delivers startup CTO services for founders in Canada and the US who need senior technical leadership without a $200K–$380K salary commitment. Not coaching. Not open-ended mentoring. A structured engagement with deliverables — covering the full stack of what an early-stage CTO actually does: technology roadmap, architecture decisions, engineering hiring, and hands-on build when your team needs it. From pre-seed through Series A, the engagement depth scales with your stage.

Who This Is For: Founders Who Need a Startup CTO Without the Full-Time Price Tag

Founders and early-stage leaders at every technical comfort level — from first-time entrepreneurs to experienced product builders.

The Non-Technical Founder

"I have deep domain expertise but I go quiet when engineers talk infrastructure. I need a technical co-pilot who translates technology decisions into business outcomes — and holds engineers accountable to the roadmap."

The First-Time CTO

"I can build the product but I've never run an engineering org, set up a hiring process, or presented a technical strategy to a board. I need a senior perspective without the politics of hiring above me."

The Founder Preparing to Fundraise

"My raise is 3-6 months away. I need investor-ready documentation, a credible scalability story, and someone to pressure-test our architecture before a VC's technical advisor does it for me."

The Solo Technical Founder Drowning in Build

"I'm both the CTO and the only engineer. I need someone to help me make the right architecture calls and hiring decisions before I build myself into a corner I can't scale out of."

Startup CTO engagement: pre-seed, seed, and Series A technical leadership tracks

Stage-Specific CTO Leadership: Pre-Seed, Seed, and Series A

A startup CTO does very different work at each stage. We adapt the focus — and depth of involvement — to where you actually are.

Pre-Seed

Validate your technical assumptions before spending engineering budget. Scope the MVP that tests your core hypothesis. Build a technology story credible to angel investors — and make the first architecture decisions you'll live with for years.

Focus Areas

Idea validation, MVP scope, first hire brief, angel pitch narrative, early architecture choices

Seed

Build an architectural foundation that survives 10x growth. Establish engineering processes, hiring criteria, and documentation your team can actually follow. Prepare the technical narrative for institutional fundraising before the round opens.

Focus Areas

Architecture decision records, scalability review, due diligence package, engineering team structure

Series A

Prepare for technical due diligence by institutional investors. Articulate your technology moat. Establish governance structures — incident management, security posture, SDLC — with investor-grade documentation to match.

Focus Areas

Due diligence prep, CTO succession, engineering KPIs, investor-grade documentation, board reporting

How Our Startup CTO Engagement Works

A structured program designed to leave you stronger and more independent — not to create ongoing dependency on an outside advisor.

01

Discovery Call

Free · 60 min

A 60-minute session to map your current landscape and identify the 3 highest-risk technical decisions in your next 90 days. You leave with a prioritized risk register regardless of next steps. (For a deeper baseline, the $2,000 Technology Health Check delivers a full written report.)

02

Engagement Design

Week 1

Define scope — which deliverables, what depth of involvement, what cadence. Advisory-only, embedded part-time, or full hands-on build. No open-ended retainer without clear milestones.

03

Structured Delivery Sprints

Weeks 2–12

Bi-weekly working sessions and async support. Every session produces a decision log, architecture record, or artifact. Hands-on work happens where advisory alone isn't enough.

04

Handoff & Independence

Week 12+

All decisions documented, artifacts handed off, team briefed. Assess whether continued engagement adds value — we never recommend ongoing retainers you don't need.

Decision gate:

After the discovery call and after each sprint, you decide whether to deepen the engagement. No multi-year contracts, no lock-in at any stage.

Full-Time CTO vs. Startup CTO Services

Why the full-time hire doesn't make sense before Series A.

Reyem Tech Startup CTO Full-Time CTO Hire
Time to first value 2 weeks (Health Check) 3-6 months (hiring cycle)
Annual cost Scales with engagement depth $230K–$380K total comp
Commitment Sprint-based, cancel anytime 12-24 month runway commitment
Depth of involvement Advisory through full execution Full-time only
Artifacts on day one Risk register after session 1 Onboarding for weeks first
Equity dilution None 0.5–2% typical founder package

Who This Is NOT For

You need a permanent, full-time CTO on your leadership team (consider our Fractional CTO service)

You're post-Series B and need enterprise-scale engineering org design

You want someone to manage your existing dev agency or outsourced team without technical depth

You're looking for generic business coaching without hands-on technical accountability

How We Engage on Startup CTO

Applicable engagement depths — pick the one that matches where you are. Each is a real, scoped engagement, not a vague consultation.

Technology Health Check

For founders, the Health Check zeroes in on the early decisions that quietly burn runway — risky architecture and the wrong or missing first hires. It's the standard $2,000 fixed-scope review of your stack, architecture, team, and risk, with a written report and a 60-minute readout in about two weeks. Ongoing CTO leadership and hands-on build live in the advisory and hands-on tiers.

Advisory

Ongoing Startup CTO advisory on retainer: technology roadmap guidance, architecture decision support, vendor and build-vs-buy evaluation, engineering hiring plan, and investor-ready documentation — you drive the roadmap, we keep you from costly wrong turns.

Hands-on management

We embed as your part-time technical leader: owning architecture decisions, running engineering sprint reviews, unblocking your team on hard technical calls, and directly writing architecture decision records and investor-grade documentation — not advising from a distance.

Full execution

End-to-end MVP delivery: we take full ownership of your technical build — architecture, engineering, QA, and handoff — from validated spec to a production system your team inherits. No agency management overhead; we are accountable to the outcome.

The Reyem Tech ladder

Four buyable rungs. Pick the one that matches where you are. Each step is a real, productized engagement — not a vague consultation.

Frequently Asked Questions

A startup CTO makes the decisions that are easy to get wrong and expensive to undo: which technology stack to build on, when to build versus buy, how to structure your first engineering hires, and how to document your architecture for investors. At the earliest stages, they are often also hands-on — writing code, reviewing PRs, and setting technical standards that the team inherits. Our Startup CTO engagement covers all of this, scaled to your stage.

The terms overlap, but the emphasis differs. Fractional CTO typically means a part-time executive embedded in your leadership team — recurring operational presence, board meetings, team management. Startup CTO services covers a broader range of depth: from structured advisory programs (deliverables, fixed timeline) through full fractional embedding. We match the engagement model to your actual stage — advisory is right pre-seed; embedded fractional CTO is right when you are scaling engineering toward Series A.

Pricing follows our engagement ladder, scoped to your stage. The $2,000 Technology Health Check is the entry; advisory is from $2,750/month; embedded fractional-CTO leadership is from $8,000/month (scaling with days per week); and end-to-end MVP delivery — fractional CTO plus developers at $50–$100/hour — typically runs $30K–$150K. Compare to a full-time CTO at $230K–$380K in total comp — or a bad early architecture decision costing $200K+ to undo at Series A. These are typical averages for planning only — actual cost is assessed per project and scope, and is not a guaranteed price. We share specifics on the first call.

Founders who get structured technical guidance before committing to a stack spend 40% less Series A engineering budget on rework. The decisions that are hardest to fix — monolith vs. microservices, cloud provider, auth architecture, data model — are the ones you make in the first 90 days. Early guidance does not slow you down; it stops you from building yourself into a corner.

That is exactly what this service is for. We function as your technical co-pilot: translating business goals into architecture decisions, evaluating vendors and candidates you cannot assess on your own, and ensuring your technology story is coherent before investors test it. We do not replace a future technical hire — we get you to the point where you can make that hire confidently.

Pure advisory fees typically do not qualify for SR&ED on their own, but the engineering work that flows from the engagement — novel integrations, custom architecture, systematic technical experimentation — often does. IRAP grants can cover a broader scope of advisory activities when the engagement involves mentoring your engineering team or supporting technical development projects. We are not SR&ED or IRAP specialists, but we structure our work to support a claim and strongly recommend pairing with a qualified funding consultant for eligibility questions.

Our standard model is fixed-fee — predictable cost, no dilution. For very early-stage startups with constrained capital, hybrid arrangements (reduced fee plus a small equity stake) are considered case-by-case. We are transparent about all terms in the first conversation.

You own all artifacts — architecture decision records, roadmap, hiring plan, investor documentation. Options at the end of a program: continue with another sprint, transition to an ongoing fractional CTO retainer, or execute independently. No lock-in by design. Our measure of success is leaving your team stronger, not creating dependency on us.

The Technical Health Check can typically be scheduled within 1-2 weeks of first contact. A structured advisory engagement can begin within 2-3 weeks — after a 60-minute discovery session to confirm fit and scope the right engagement depth. We do not take every engagement that comes in; the fit conversation matters.

A Technology Health Check is a fixed-scope engagement. Two weeks, written report, clear next steps — no open-ended commitment.
