A CTO's judgement, on the days you need it — at a fraction of a full-time hire.
Most Indian startups and SMEs reach a point where the product works but the technology underneath does not scale: a monolith nobody wants to touch, an agency that owns the code, a cloud bill growing faster than revenue and no one who can answer an investor's architecture questions. A full-time CTO costs a crore or more a year with ESOPs and takes months to hire.
vCTO as a Service gives you a senior technology leader from XcellHost for 16 to 80 hours a month. They set the architecture, run engineering rituals, choose what to build and what to buy, track DORA metrics, bring cloud spend under control, design security in for the DPDP Act and SOC 2, and write the board's tech memo — backed by a team that has run production infrastructure from Mumbai since 1999.
Two weeks to understand you. Every month after that, we lead.
The engagement starts with a hands-on assessment, turns into a blueprint and roadmap, then runs as a monthly retainer with a named vCTO.
A two-week tech health check
We read the code, the cloud bill, the incident history and the team set-up, and talk to founders, engineers and your agency. You get a scored risk register, not a slide deck.
- Architecture & code review
- Cloud bill and licence review
- Scored risk register
Blueprint, roadmap and hiring plan
A target architecture with build-vs-buy calls, a 12-month product-tech roadmap tied to your milestones, a cloud cost plan and the hiring plan to deliver it.
- Architecture blueprint
- 12-month roadmap
- Hiring plan, JDs & interview kits
A named vCTO, every month
Sprint reviews, architecture decisions, code-quality gates, vendor and agency oversight, a DORA dashboard and a monthly board-ready tech memo. Scale adds interim CTO cover.
- SDLC, DevOps & DORA
- Agency & vendor oversight
- Board & investor reporting
From first audit to board meeting — scroll through a vCTO engagement.
Five stages. Watch the same pieces of your technology move from scattered to scored, layered, scheduled, shipping and reported.
- 01Weeks 1–2Assess
We map every service, repo, vendor and cloud account, then score each one for risk, cost and how much it slows the team down. Red flags come first.
Tech health check · risk register - 02Weeks 2–4Strategy
The same pieces fall into a target architecture: edge, application, data and AI layers. Commodity parts are bought, core IP is built, cloud and security choices are written down.
Architecture blueprint · build-vs-buy - 03Weeks 4–5Roadmap
Work becomes a 12-month product-tech roadmap across platform, product, data & AI and team — sequenced against your fundraising and launch dates, with the hires to deliver it.

Your vCTO runs the engineering system: planning, code-review gates, CI/CD, release discipline and agency oversight. Work flows to production in small, safe batches.
SDLC & DevOps · DORA dashboard - 05Monthly · quarterlyReview
DORA metrics, cloud spend, risks and roadmap progress go into a one-page board tech memo. Each quarter we re-plan against what the business now needs.

Seven areas a CTO is accountable for — covered, from day one.
Pick an area to see what we do in it. Most clients use all seven; the hours move to wherever the business needs them that month.
Technology vision & architecture
A target architecture that fits your stage — modular before micro, managed services before self-hosting, cloud-native where it pays. Every decision is written as a short architecture decision record your team can follow.
- Edge, app, data and AI layers defined
- Monolith-to-modular plan, no big-bang rewrite
- Architecture decision records (ADRs)
Product engineering leadership
Team structure, hiring and the rituals that make a team ship: planning, code review, testing standards and release discipline. We oversee agencies and freelancers so you own your code and your roadmap.
- Org design, JDs and interview kits
- Code-quality gates and review standards
- Agency & vendor oversight, IP in your repos
Build vs buy, decided on evidence
Every component is placed on one question: is this where you win? Commodity capabilities — login, payments, notifications, search — are bought or integrated. Engineering time goes into the parts that make you different.
- Differentiation vs effort matrix
- Three-year cost of each option
- Vendor shortlists and exit plans
Cloud cost & FinOps
Tagging, budgets and unit costs per customer or transaction, then the usual levers: rightsizing, commitments, idle clean-up, storage tiering and architecture fixes. AWS, Azure, GCP or Indian cloud — chosen on merit.
- Unit economics: cost per customer
- Rightsizing & autoscaling
- Budgets and anomaly alerts
Security by design
Security decisions made while the system is designed, not after a breach: OWASP-aware code review, secrets management, MFA everywhere, backups that are tested, and personal-data handling that matches the DPDP Act. SOC 2 readiness when enterprise customers ask.
- DPDP-aligned data flows and consent
- OWASP Top 10 in the review checklist
- SOC 2 / ISO 27001 readiness path
AI strategy & responsible AI
Where AI actually moves a metric for you, what it costs to run, and how to keep customer data safe while doing it. We take ideas from a long list to one measured pilot, with evaluation, guardrails and a cost ceiling.
- Use-case scoring by value and feasibility
- Model, vendor and hosting choices
- Guardrails, evaluation and PII controls
Board reporting & tech due diligence
A monthly one-page tech memo your board can read in five minutes, and a data room that survives an investor's technical due diligence: architecture, security, scalability, team, IP and open-source licences.
- Monthly board tech memo
- Due-diligence readiness review
- IP and open-source licence check
Before and after — in money and in delivery speed.
Two illustrations of where a vCTO's time pays back. Move the slider to your own cloud bill. Figures are typical ranges and samples, not a promise — your numbers come from the assessment.
Typical FinOps lever ranges applied to the remaining bill, midpoint shown. Estimates only — a costed review confirms them.
Sample before/after for a 12-person product team. Ring = distance to “elite” on each DORA metric. Illustrative, not a client result.
Rate eight areas. See your shape, your score and the plan that fits.
Be honest — 1 is “we wing it”, 5 is “measured and improving”. Start from a typical profile if it's quicker. The green outline is an illustrative 12-month target.
Full-time CTO or vCTO? Compare year-one cost and time to value.
Set the hire you'd otherwise make. Salary bands are broad Indian market ranges we use as a starting point — change them to your own numbers.
Assumptions: benefits & overheads 15% of CTC; recruiter fee 20% of CTC; ESOP valued at grant % × valuation over 4-year vesting; 2 months ramp-up after joining. Market salaries vary widely — illustrative only. vCTO prices indicative, excl. 18% GST.

Four ways to get technology leadership. One fits most companies under 50 engineers.
A fair comparison. A full-time CTO is the right answer eventually — we help you hire one when you get there.
| Full-time CTO | Agency's tech lead | Freelance advisor | XcellHost vCTO | |
|---|---|---|---|---|
| Time to start | 3–9 months to hire | Immediate | 2–4 weeks | About 2 weeks |
| Year-one cost | CTC + overheads + recruiter + ESOP | Bundled into dev billing | Hourly, variable | Fixed monthly retainer in INR |
| Independent of who writes the code | Yes | No — reviews its own work | Yes | Yes — we don't bill you for development hours |
| Board & investor reporting | Yes | Rarely | Sometimes | Monthly memo · due-diligence ready |
| Security & compliance depth | Depends on the hire | Depends on the agency | Depends on the person | Backed by our ISO 27001 & SOC 2 practice |
| Production operations behind them | You build it | Limited | No | 24×7 NOC & SOC, Mumbai |
| Continuity if someone leaves | Single point of failure | Team rotates | Single point of failure | Named vCTO plus a bench |
| Hours of attention | Full time | As needed | As needed | 16–80 h / month · flex with extra hours |
The rules your product runs under — designed in, not patched later.
A CTO in India has to know more than cloud and code. These are the obligations we build into architecture and process from the first month.
DPDP Act, 2023
Purpose-limited data collection, consent records, retention rules, breach response and “reasonable security safeguards” designed into your data flows.
CERT-In directions
Incident reporting within 6 hours, logs kept for 180 days, clocks synchronised — built into logging, alerting and your incident runbook.
RBI & SEBI expectations
Selling to banks, NBFCs or brokers? Their IT outsourcing and cyber-resilience frameworks flow down to you as vendor questionnaires and audits.
MeitY cloud & data location
Government and regulated customers may need MeitY-empanelled cloud or India-only data. We design for it before a deal depends on it.
GST, e-invoicing & UPI
Billing, IRP e-invoicing APIs, payment gateways and UPI flows — the integrations Indian products live or die on, chosen and reviewed.
SOC 2 for export SaaS
US and EU buyers ask for SOC 2 or ISO 27001. We plan the controls into the roadmap and hand over to our Managed GRC team.
XcellHost has run regulated infrastructure from Mumbai since 1999 — ISO 27001, 27017, 27018 and 20000-1 certified, SOC 2 Type I & II, MeitY empanelled.
Guidance only — confirm obligations with your legal and compliance advisers.A monthly retainer for leadership, sprints for one-off questions — in rupees, with GST.
Pick a retainer by hours, add a sprint if you need a fixed-scope answer, and top up with extra hours in busy months. All prices are indicative and exclude 18% GST.
Growth
Choose a retainer
Indicative placeholders until confirmed on your quotation. Retainers run on a 3-month minimum term. Development, cloud and third-party tool costs are billed separately or paid directly by you.
Advice from people who run production. Every day, since 1999.
Strategy is only useful if it survives contact with real systems. Our vCTOs sit on top of a company that operates infrastructure, security and compliance for Indian businesses around the clock.
Backed by our 24×7 NOC & SOC in Mumbai — the people who answer when production breaks at 3 a.m.
01We don't sell you development hours, so architecture and vendor advice isn't shaped by who gets the build.
02AWS, Azure, GCP or an Indian cloud — recommended on cost, compliance and fit, with the numbers shown.
03ISO 27001, 27017, 27018, 20000-1 and SOC 2 in our own operations; DPDP and CERT-In designed into yours.
04One accountable leader, with cloud, security and data specialists behind them — no single point of failure.
05Monthly billing in rupees — UPI, card, net banking or transfer. Scale up or down each term.
