CTO as a Service
Fractional CTO and tech lead from EltexSoft. Architecture, team scaling, vendor evaluation, due diligence. HeyTutor (8+ yr de facto CTO). $50-99/hr.
EltexSoft provides fractional CTO and tech lead as a service for startups and growth-stage companies that need senior technical leadership without a full-time C-suite hire. Our co-founder Illia has served as de facto CTO for HeyTutor for 8+ years, owning architecture, infrastructure, hiring, and technical strategy. We also provide tech-lead-level CTO functions for SoRipe and other long-term clients. $50-99/hr.
What we ship
The Work
-
Architecture and Technical Strategy
Stack selection, system design, scalability planning, build-vs-buy decisions, technical roadmap. The decisions that are expensive to reverse once code is written.
-
Team Building and Scaling
Hiring plans, technical interviews, onboarding processes, engineering culture, performance standards. How to go from 2 engineers to 20 without losing velocity.
-
Infrastructure and DevOps
CI/CD pipelines, cloud architecture, monitoring, incident response, cost optimization. The foundation that determines whether your engineering team ships daily or monthly.
-
Technical Due Diligence
Pre-acquisition code audits, security assessments, architecture reviews, scalability analysis. What investors and acquirers need to see before writing a check.
-
Vendor and Partner Evaluation
Evaluating development agencies, SaaS vendors, API providers, and technology partners. Objective technical assessment without the conflicts of interest that come from selling services.
-
Legacy Rescue and Modernization
Inheriting codebases from prior contractors, stabilizing production, establishing CI/CD, documentation, and test coverage. The first 90 days of a fractional CTO engagement.
Most Startups Don’t Need a $300K CTO. They Need CTO-Level Decisions Made Correctly.
A full-time CTO costs $200K-$400K in base salary, plus equity, plus benefits. For a Series A company with 5-15 engineers, that is the right hire. For a seed-stage startup, a bootstrapped company, or a growth-stage business that has product-market fit but no senior technical leader, it is a misallocation of capital.
What these companies actually need: someone who makes the architecture decisions correctly, sets up infrastructure that does not catch fire at 2 AM, builds a hiring process that attracts engineers who stay, evaluates vendors without conflicts of interest, and creates a technical roadmap that aligns with the business plan. They need a fractional CTO.
EltexSoft provides CTO as a service and tech lead as a service. Our co-founder Illia has been the de facto CTO of HeyTutor for over 8 years. Not an advisor. Not a consultant who visits quarterly. The person who owns the architecture, the infrastructure, the CI/CD pipelines, the hiring decisions, and the technology strategy. HeyTutor does not have a separate CTO because they do not need one.
How It Works in Practice
HeyTutor: De Facto CTO for 8+ Years
HeyTutor is an EdTech platform connecting students with tutors. Illia has been their technical leader since the early days of the product. What that looks like in practice:
Architecture ownership. Stack selection, database design, API architecture, third-party integration decisions. Every technical decision that is expensive to reverse runs through Illia before code is written.
Infrastructure from day one. CI/CD pipelines with on-demand development environments. Dev-staging-production workflow. Slack integrations for deployment notifications, monitoring alerts, and build status. Automated testing in the pipeline. This is not infrastructure that was added later. It was set up on day one because that is how Illia starts every engagement.
Team scaling. As HeyTutor grew, the engineering team grew with it. Illia manages the hiring process: defining the role, conducting technical interviews, making offers, and onboarding. The engineers are EltexSoft team members, which means the technical leader and the team work at the same company, share the same standards, and communicate daily.
Technical strategy. What to build next, what to defer, what to kill. When to use a third-party service and when to build in-house. When to refactor and when to leave working code alone. The judgement calls that a CEO cannot make alone.
SoRipe: Tech Lead as CTO
For SoRipe (the meal kit platform acquired by Hungry), our tech lead performed CTO-level functions: architecture decisions, infrastructure management, team coordination, and technical due diligence preparation ahead of the acquisition. The acquisition outcome validated the approach: the technical foundation passed buyer due diligence.
What a Fractional CTO From EltexSoft Does
Architecture and system design. Stack selection, database design, API architecture, microservices vs monolith decisions, scalability planning, build-vs-buy analysis. The decisions that shape your engineering for years.
Infrastructure and DevOps. CI/CD pipelines from day one. Cloud architecture (AWS, GCP). Monitoring and alerting. Incident response procedures. Cost optimization. On-demand dev environments. The foundation that determines whether your engineering team ships daily or monthly.
Team building. Hiring plans, technical interview processes, onboarding, code review standards, engineering culture, performance management. How to scale from 2 engineers to 20 without losing velocity or quality.
Technical due diligence. For fundraising, for acquisition, or for your own peace of mind. Codebase audit, security assessment, architecture review, scalability analysis, dependency risk mapping, and a report that investors or acquirers can read.
Vendor evaluation. Evaluating development agencies, SaaS providers, API vendors, and technology partners. When a vendor claims their product does X, a fractional CTO verifies it before you sign a contract.
Legacy rescue. Inheriting a codebase from a prior contractor who left no documentation. Stabilizing production. Establishing CI/CD where none exists. Writing the tests that should have been written from the start. The first 90 days of most fractional CTO engagements start here.
What the First 90 Days Look Like
Weeks 1-2. Codebase audit. Infrastructure review. Team assessment. Documentation of current state. Identification of critical risks (security vulnerabilities, single points of failure, missing backups, no CI/CD).
Weeks 3-6. Stabilize critical issues. Establish CI/CD if missing. Introduce monitoring and alerting. Set up dev-staging-production workflow. Document deployment procedures. Fix the things that will cause an outage if left alone.
Weeks 7-12. Technical roadmap for the next 6-12 months. Hiring plan. Architecture decisions for upcoming features. Vendor evaluation for any planned integrations. Quarterly planning with the CEO/founder.
After 90 days. Monthly retainer. Weekly architecture reviews. Sprint planning participation. Pull request reviews for critical systems. Infrastructure monitoring. Hiring support. Vendor negotiations. Quarterly roadmap updates.
What It Costs
Fractional CTO / tech lead as a service: $50-99/hr on a retained basis.
A typical engagement runs 20-40 hours per month: $4,000-$16,000/month.
Compare to:
Full-time CTO: $200K-$400K/year base salary, plus equity, plus benefits.
US-based fractional CTO: $200-$500/hr.
Management consulting firm: $300-$600/hr for a principal, with junior analysts doing the actual work.
Our model: a senior engineer who has been a production CTO for multiple companies, available at the rate of an Eastern European senior developer, with the judgement that comes from 11 years of shipping software for startups and growth-stage companies.
