CTO as a Service

Senior technology leadership for companies where the platform is the business. RHC Solutions provides CTO as a Service — fractional, interim and virtual CTO (vCTO) engagements that own your architecture, engineering team, scalability, security, and regulatory readiness — for startups, FinTech, online trading, and iGaming operators that need a seasoned CTO now, without the cost and delay of a full-time hire.

In a startup, a FinTech, a brokerage or an iGaming operator, technology decisions are business decisions. The wrong architecture caps your growth, an unplanned outage during market open or a major cup final costs revenue and reputation, and a failed audit or licence review can stop you trading altogether. A fractional CTO — also called a virtual CTO (vCTO), interim CTO, part-time CTO or CTO on demand — gives you an experienced technology executive who owns those decisions: platform architecture, build-vs-buy, engineering hiring and delivery, uptime under peak load, security and compliance by design, and the technical story your investors, regulators and partners need to hear. You get senior judgment from day one, on a monthly retainer sized to the days you actually need.

Who CTO as a Service is for

Startups & Scale-ups

From MVP to Series B: choose a stack that won't need a rewrite, ship the MVP fast, hire and lead your first engineers, control cloud spend, and pass investor technical due diligence. When enterprise customers ask for SOC 2 or ISO 27001, your platform is already designed to be audit-ready.

FinTech

Payments, lending, neobanking, wallets and embedded finance. We design auditable ledgers, idempotent payment flows, KYC/AML and open-banking integrations, and secure-by-design platforms ready for PCI DSS, SOC 2, ISO 27001 and, for EU-regulated firms, DORA operational-resilience requirements.

Online Trading

Brokers, prop-trading firms, investment apps and crypto exchanges. We own low-latency architecture, FIX and market-data connectivity, MT4/MT5 and cTrader bridges, order management and risk systems, capacity for market-open and news spikes, and the record-keeping and reporting your regulator expects.

iGaming

Online casino, sportsbook and B2B game suppliers. We lead player account management (PAM) and game-aggregation architecture, payment orchestration, geolocation and responsible-gambling controls, DDoS resilience and peak-event scaling, and prepare your platform for licensing and certification with regulators such as the MGA, UKGC and testing labs like GLI. RHC prepares the technology, controls, and evidence regulators and test labs review; licensing decisions rest with the regulator, and we work alongside your legal and compliance advisers.

What your fractional CTO delivers

Technology Strategy & Architecture

A product and technology roadmap tied to your business plan, target architecture, stack decisions and an honest view of technical debt — what to fix now, what can wait.

Engineering Team Leadership

Hiring plans, interviews and onboarding, org design, delivery cadence and engineering KPIs — plus oversight of offshore teams and development agencies so you get what you pay for.

Scalability & Reliability

Cloud architecture, observability, service-level objectives (SLOs), load testing and incident management so the platform holds up when traffic spikes — at market open, on a big match day or after a funding announcement.

Security & Compliance by Design

Secure software development lifecycle (SDLC), identity and secrets management, data protection and audit trails built in from the start, with readiness for PCI DSS, SOC 2, ISO 27001, DORA and sector licensing reviews.

Vendor & Build-vs-Buy Decisions

Independent selection of payment service providers (PSPs), KYC providers, trading platforms, PAM and game aggregators, cloud and SaaS — with contract, lock-in and total-cost analysis before you sign.

Investor & Board Readiness

Technical due diligence preparation for fundraising or M&A, board-level technology reporting, and a credible, documented platform story for investors, banks and regulators.

When to hire a fractional CTO

You are a non-technical founder building on an agency or freelancers and need someone senior on your side of the table
You are raising a round or preparing for an acquisition and need to pass technical due diligence
Your platform struggles under load — at market open, during major sporting events or after a marketing push
You are entering a regulated market, applying for a licence, or onboarding a partner bank, PSP or liquidity provider
Your CTO has left and you need interim leadership while you recruit a permanent replacement
Engineering spend is growing faster than delivery and you need an independent view of the team, the code and the vendors

How we engage

Every engagement starts with a two-to-three-week technical assessment: architecture, code quality, infrastructure, security posture, team, vendors and spend — benchmarked against the standards your sector and regulators expect. You receive a prioritized 30/60/90-day plan and a 12-month technology roadmap. From there your fractional CTO works on a regular cadence: architecture and product decisions, sprint and delivery oversight, hiring, vendor management, incident reviews and investor or board reporting — scaled to the days per month you need. We hand over cleanly to a permanent CTO when the time comes, and can help you recruit and onboard them.

What CTO as a Service costs

CTO as a Service runs on a fixed monthly retainer scaled to your stage — from a few strategic days a month for an early-stage startup, to near full-time interim coverage during a platform rebuild, licence application or leadership gap. That is a fraction of the typical $250k+ fully loaded cost of a full-time chief technology officer, with no recruiting delay, no equity dilution and no long-term commitment. Engagements are remote-first and month-to-month, so you get senior technology leadership within days and adjust the level as your company grows.

Frequently Asked Questions

What is CTO as a Service?

CTO as a Service is executive technology leadership on a fractional, interim or virtual (vCTO) basis. An experienced CTO owns your architecture, engineering team, scalability, security and technology roadmap part-time, on a monthly retainer, instead of you hiring a full-time CTO.

What does a fractional CTO do for a startup?

A fractional CTO chooses the right stack and architecture, scopes and oversees the MVP, hires and leads the first engineers, keeps cloud costs under control, and prepares the company for investor technical due diligence and enterprise security requirements such as SOC 2.

Why do FinTech and online trading companies need a specialized CTO?

Their platforms move money and are regulated. The CTO must design auditable ledgers and payment flows, low-latency and highly available trading systems, and security and record-keeping that satisfy frameworks such as PCI DSS, SOC 2, MiFID II and DORA, as well as partner banks, PSPs and liquidity providers. We prepare the technology side and work alongside your legal and compliance advisers; regulatory decisions rest with the regulator.

How does a fractional CTO help an iGaming operator?

By owning PAM and game-aggregation architecture, payment orchestration, geolocation and responsible-gambling controls, DDoS protection and peak-event scaling, and by preparing the platform for licensing and certification reviews with regulators such as the MGA and UKGC and testing labs such as GLI.

How is a fractional CTO different from a development agency?

An agency builds what it is asked to build and bills for hours. A fractional CTO sits on your side: sets the architecture and roadmap, decides what to build or buy, holds agencies and vendors accountable, and owns the outcome. Many clients use both — the CTO directs, the agency delivers.

How is CTO as a Service different from CIO as a Service?

A CTO owns the technology you build and sell — your product platform, engineering and architecture. A CIO owns the technology you run the business on — internal IT, systems and vendors. Product-led companies such as FinTech, trading and iGaming firms usually need a CTO first.

How quickly can a fractional CTO start?

Usually within days. Engagements begin with a two-to-three-week technical assessment and a prioritized 30/60/90-day plan, then continue month-to-month at the level of involvement you need.
