Fractional CTO Service

Founders can launch with agencies, no-code tools, and AI coding assistants, but they then face decisions about security, scaling, and hiring that they cannot judge. Investors increasingly want a technical lead on the team, even part-time. Experienced engineers affected by layoffs or looking for flexibility are filling this gap, so clear positioning matters.

Non-technical founders who outsourced their first build, seed-stage startups without a technical cofounder, and small companies modernizing legacy systems.

• $Monthly retainer
• $Equity plus reduced cash
• $Project-based technical due diligence

1. 1

   Define your sweet spot

   Choose the stage and domain where your experience is strongest, such as seed-stage SaaS, marketplaces, or data-heavy products.

2. 2

   Package the engagement

   Offer clear tiers, for example 8 hours a month for advisory at $2,000 to $3,000 and 2 days a week for hands-on leadership at $8,000 to $14,000.

3. 3

   Create a technical health check

   Sell a fixed-fee review of code, hosting, security, and team process for $2,500 to $6,000 as an entry offer that often leads to retainers.

4. 4

   Network with founders and investors

   Join founder communities, speak with accelerators and angel groups, and offer to review portfolio companies’ tech stacks.

5. 5

   Set boundaries in contracts

   Specify availability, response times, decision rights, and what happens if the company hires a full-time CTO. Include confidentiality and IP terms.

6. 6

   Keep clients healthy

   Run weekly check-ins, maintain a living roadmap, and document decisions so the team can operate when you are not there.

  You are my AI cofounder. We are starting this business together:
  
  Business idea: Fractional CTO Service — Provide senior technical leadership to startups a few days a month.
  Summary: A fractional CTO gives non-technical founders and small teams senior guidance on architecture, hiring, vendor choices, and delivery for a monthly retainer instead of a full-time salary. Early-stage startups and small businesses pay because bad technical decisions are expensive and a full-time CTO is out of reach. It fits experienced engineers and engineering managers who can lead without needing a large team.
  Typical startup cost: $0–$1k. Typical revenue after ~12 months: $5k–$25k/mo. Time to first revenue: 2–6 weeks.
  Target customers: Non-technical founders who outsourced their first build, seed-stage startups without a technical cofounder, and small companies modernizing legacy systems.
  Revenue models: Monthly retainer; Equity plus reduced cash; Project-based technical due diligence.
  Common channels: Founder communities and accelerators; LinkedIn thought leadership; Referrals from agencies and VCs; Speaking at startup events; Newsletter with technical lessons for founders.
  
  About me (edit this): I live in [CITY, COUNTRY]. My budget is [BUDGET]. I can spend [HOURS] hours per week. My relevant skills/experience: [SKILLS].
  
  Work autonomously and use web search. Deliver, as separate files or clearly separated sections:
  1. A demand check: 10 real signals that people in my area/market pay for this today (links to competitors, reviews, job posts, forum threads).
  2. The 5 strongest local/online competitors with pricing, positioning and one weakness each.
  3. My offer: a specific niche, 3 packages with prices, and why a customer picks me.
  4. A one-page business plan with a startup budget table under my budget.
  5. A 30-day launch checklist, day by day, with the first paying customer as the goal by day 14.
  6. Copy for a one-page website and 3 outreach messages.
  Ask me at most 3 clarifying questions first, then go. Flag anything that needs a license, permit or insurance where I live.

  3. Write the exact message I should send to 20 potential customers to test willingness to pay (not just interest).
  4. Tell me what result would make you say "don't do this".
