What Is a Fractional CTO?

A fractional CTO is a senior technical leader who works part-time with your company — usually 15 to 25 hours a week — giving you the same strategic oversight as a full-time CTO without the full-time price tag. For Series A through B SaaS startups, that means architecture decisions, engineering hiring, vendor evaluation, and investor-facing technical reporting. No $350K+ salary. No equity dilution.

プロジェクトが失敗する理由

Your investors want a technical roadmap and your board deck has a blank slide That blank slide erodes board confidence fast — and once confidence drops, follow-on fundraising gets harder and oversight gets tighter.
You're hiring engineers but nobody's actually evaluating their system design skills Bad hires compound. One wrong senior engineer can set your architecture back 12 months.
Your AWS bill tripled last quarter and nobody can explain why Uncontrolled infrastructure costs burn runway — and they signal operational immaturity to every investor who sees them.
Three vendors are pitching you and you can't tell which one is lying Wrong vendor lock-in costs $100K+ to unwind and can delay product delivery by quarters.
Technical debt is piling up but nobody's weighing it against feature work Velocity drops quarter over quarter until shipping anything takes 3× longer than it should.
Your engineering team has no career ladder, no sprint process, and no incident playbook Top engineers leave within 12 months. Replacing them runs $30K–$50K per head.

コンプライアンス

Technical Strategy & Roadmapping

We build a 6–18 month technical roadmap tied to your business milestones and fundraising timeline. Every architecture decision maps to a revenue outcome or a specific risk you're trying to eliminate.

Engineering Team Hiring

We write job specs, screen candidates, run technical interviews, and design your engineering ladder. You get the right people in seats without burning 40 hours on screening calls.

Architecture Review & Remediation

We audit your codebase, infrastructure, and data layer for scalability bottlenecks and security gaps. You get a prioritized remediation plan — not a 60-page PDF that collects dust on a shared drive.

Vendor & Tool Evaluation

We evaluate SaaS tools, cloud providers, and third-party integrations against your actual requirements and budget. Objective analysis — no affiliate links, no kickbacks.

Board & Investor Reporting

We build the technical slides for your board deck and join board meetings when it matters. Investors get straight answers about uptime, velocity, and technical risk.

SOC 2 & Security Readiness

We put access controls, audit logging, and security policies in place that enterprise customers and investors expect to see. SOC 2 Type II readiness without hiring a full compliance team.

構築する内容

Weekly Strategy Sessions

Recurring 90-minute sessions with founders to keep technical priorities aligned with business goals and your next fundraising milestone.

Async Slack Access

Direct Slack access to your fractional CTO for real-time decisions. No waiting for the next scheduled call when something's on fire.

Sprint Process Design

We put lightweight agile processes in place that actually ship software instead of just generating Jira tickets.

Due Diligence Support

Technical due diligence prep for your next funding round — code quality reports, architecture diagrams, and risk assessments that investors actually expect to see.

Incident Response Playbooks

We write and drill incident response procedures so your team handles outages without panic at 2 AM.

Build vs. Buy Analysis

Data-driven analysis for every major technical decision so you stop building commodity features that already exist as off-the-shelf services.

私たちのプロセス

01

Technical Assessment

We audit your codebase, infrastructure, team structure, and technical debt. Within the first week, you get a written assessment with severity ratings and a prioritized action plan.
Week 1
02

Strategy & Roadmap

We align your technical roadmap with your business milestones — next fundraise, enterprise launch, or compliance deadline. Every workstream gets an owner, a timeline, and a clear definition of done.
Week 2–3
03

Execution & Hiring

Then we start executing: architecture changes, hiring pipelines, vendor evaluations, process improvements. Your team sees measurable velocity improvements, not just slide decks.
Month 1–3
04

Board Integration

We build your first technical board report and establish the KPIs that matter — deployment frequency, incident response time, infrastructure cost per customer. Investors stop asking uncomfortable questions.
Month 2–4
05

Transition or Retain

When you're ready for a full-time CTO, we write the job spec, screen candidates, and run a structured handoff. Many clients keep us on through Series B. Honestly, both paths work fine.

よくある質問

フラクショナル CTO とテクニカルコンサルタントの違いは何ですか?

コンサルタントはレポートを作成して去ります。フラクショナル CTO はあなたのチームに組み込まれ、スタンドアップに参加し、採用判断を下し、ボード会議に出席し、数ヶ月または数年にわたって技術成果を所有します。私たちは納品物ではなく成果に対して責任を持ちます。

フラクショナル CTO は週何時間働きますか?

通常、エンゲージメントティアに応じて週 15~25 時間です。これには創業者との戦略セッション、非同期 Slack 対応、エンジニアリングチームとのやり取り、アーキテクチャ作業、ボード準備が含まれます。ほとんどの Series A スタートアップでは週 20 時間がちょうど良いバランスです。

報酬としてエクイティを受け取りますか?

いいえ。現金のみの月額リテーナーで契約しています。エクイティは利益相反を生じさせます。ビルド vs バイ、チーム変更、技術方向性について、キャップテーブルに利害関係がない中立な助言を提供したいのです。

後でフルタイムの CTO を採用するのを手伝ってくれますか?

はい。ほとんどのエンゲージメントには計画的な移行が含まれています。職務経歴書を作成し、ネットワークを通じて候補者を探し、技術面接を実施し、構造化された 30 日間の引き継ぎを管理します。当社の紹介の多くは、私たちのプロフェッショナルネットワークからの直接紹介から生まれています。

どんな SaaS テックスタックに対応していますか?

Next.js、React、Node.js、Python、Go、PostgreSQL、AWS、GCP、Vercel、Supabase など、モダンな SaaS スタックに対応しています。推奨事項ではスタックにとらわれません。Rails や Elixir があなたの最適な選択なら、そう伝えて採用を支援します。

どのくらいの速さで開始できますか?

ほとんどのエンゲージメントは署名後 1 週間以内に開始されます。最初の 5 営業日以内に有料技術評価を実施し、優先順位付きの推奨事項を含む書面レポートを提供します。その後、最も影響の大きい項目の実行に直ちに進みます。
