A year in, and no launch. When JetSynthesys brought me in to look at RightLife, its new health app, the agency building it had missed four launch dates and was about to miss a fifth. Every update had sounded reasonable. Nobody on the leadership team could tell what was really going on.
If you run a business that works, you'll recognise the feeling. You know your customers, your margins and your market. But the moment you need software built, you're relying on people you can't judge, quoting prices you can't check.
That gap is what a fractional CTO fills: a senior technology leader who sits on your side of the table for one or two days a week. Almost everything you'll read about fractional CTOs is written for startup founders, or by marketplaces that sell them by the hour. This guide is written for owners of established Indian businesses: what a fractional CTO actually does, what one costs in rupees, when you need one, and when you don't.
What is a fractional CTO, really?
A chief technology officer (CTO) owns the technology decisions in a business: what gets built, how it's built, who builds it and what it costs. A fractional CTO does the same job for a fraction of the week. You get the judgment of someone who has built products for years, without a full-time salary or a six-month search.
A typical engagement takes 8–16 hours a week, or one to two days (Idealogic). Mine are usually 1–2 days a week, and they last until the product is live and there's a team or vendor who can carry it forward.
Fractional CTO, interim CTO, advisor or agency tech lead?
These titles get used loosely, and vendors use the confusion. Here's how they differ in practice:
| Role | Time | Accountable for outcomes? | Independent of the builder? | Typical use |
|---|---|---|---|---|
| Fractional CTO | 1–2 days a week, ongoing | Yes | Should be | Leading a build or a technology function |
| Interim CTO | Full-time, temporary | Yes | Yes | Covering a gap between hires |
| Technical advisor | A few hours a month | No, advice only | Yes | Sounding board for the owner |
| Agency "tech lead" | Whatever the project needs | To the agency | No | Running the agency's own delivery |
The last row matters most. An agency's tech lead may be excellent, but their job is to deliver what the agency sold you. A fractional CTO's job is to tell you whether that was the right thing to buy.

What a fractional CTO does for a non-tech business
For an established business building its first product, the work usually falls into four stages.
01Shape the product
Turn the business idea into a clear plan: what the product must do on day one, what can wait, how it should be built and what it will realistically cost. This is where most of the money is saved, because the cheapest feature is the one you don't build.
02Pick the team
Decide whether to hire an agency, build an in-house team or buy something off the shelf. Then choose the vendor, and write the technical side of the contract so you own your code, servers and data.
03Lead the build
Review the work, make the technical calls and keep the project on track. You get updates in business language, not a status report full of jargon.
04Hand over
When the product is live, you get documentation, a team or vendor you can manage, and a roadmap for what's next. A good one is working towards the day you no longer need them.
Here's what that looks like on a real project. A2Z Group's facility management business runs a workforce of more than 12,000 people across over 100 client sites. When Kanika Mittal, A2Z's COO, brought me in, attendance, onboarding, transfers and payroll all ran on Google Sheets and an outdated payroll system.
We tested several off-the-shelf HR products against four questions: would a low-literacy workforce actually use it, could it handle people who leave and come back, could it run on A2Z's own infrastructure, and could A2Z afford it without per-employee pricing? None passed all four.
So I chose an open-source platform with no per-user fees, plus a delivery partner to customise it. That way costs don't grow with headcount. Here's how we took A2Z from spreadsheets to one system for 12,000+ workers.
Notice what I didn't do there: write the code. The value was in asking the right four questions before A2Z signed anything.
What does a fractional CTO cost in India?
Published rates vary a lot, and most come from recruiters and vendors. Treat them as market ranges, not price lists.
| Engagement | Published range | Time | Source |
|---|---|---|---|
| Advisory | ₹40,000–80,000 a month | 4–8 hours a month | Startupbricks |
| Fractional, part-time | ₹1.2–2.5 lakh a month | 1–2 days a week | Startupbricks |
| Fractional, senior | ₹3–5 lakh a month | 15–18 hours a week | Synaplab |
| Fractional, principal | ₹6–10 lakh a month | 20–25 hours a week | Synaplab |
| Full-time CTO, mid-size company | ₹45 lakh–1.2 crore a year | Full-time | Crescendo Global |
For comparison, US fractional CTOs often charge $8,000–25,000 a month (Groovyweb). That's one reason international companies setting up development centres in India look for one here.
What moves the price
- Hours a week. This drives the price more than anything else.
- Seniority. Has this person led products to launch, or only managed engineers?
- Scope. Advising on one decision costs less than running a whole build.
- Duration. A fixed 3–4 week scoping exercise is priced differently from a 12-month retainer.
GST, TDS and the paperwork
A part-time CTO is a contractor, not an employee. If they're GST-registered, add 18% GST to the invoice. Your accounts team will usually deduct TDS on professional fees before paying, so ask your CA which section applies. Either way, put the scope, notice period, confidentiality and IP ownership in writing.
The real comparison isn't the salary
Most articles compare a fractional CTO with a full-time CTO's salary. For an established business, that's rarely the real choice. The real choice is between a fractional CTO and trusting the agency on your own.
So run the numbers that way. Say an agency bills ₹8 lakh a month and the project slips six months. That's ₹48 lakh, before you count the sales you didn't make while waiting. A fractional CTO at ₹2 lakh a month for the same year costs ₹24 lakh, and the main thing you're paying for is avoiding that slip.
RightLife is the version of this I lived through. My audit found three things the agency hadn't flagged.
Servers had been provisioned for scale before the app had a single user, and restructuring them cut monthly server costs by about 66%. Nobody had checked the app against Apple's and Google's rules for health apps, which would have blocked the launch outright. And the team was stuck on the last 20% of features the launch didn't need.
We launched on the fifth date, the one the agency was about to miss. Later, an in-house team of 10 produced 1.8x the output of the 18-person agency team. Read how we shipped after four missed launch dates.

When you need a fractional CTO, and when you don't
Six signs you need one
- You're about to spend more than about ₹15–20 lakh on software, and nobody on your side has bought software before.
- You have three agency quotes for the same brief, and the prices differ by 3x or more.
- Your project has missed a deadline, and the explanations all sound reasonable.
- Your code, servers or app store accounts are in the vendor's name, not yours.
- You're being sold AI and can't tell whether it's real or a demo.
- You need a technology leader, but a full-time hire is too big a bet right now.
When a full-time CTO is the better hire
Hire full-time when technology is the product and decisions come in every day, not every week. That usually means you're running an engineering team of 10–15 or more, or raising money from investors who expect a technical co-founder. A fractional CTO can help you hire that person, and often should.
When you need neither
Sometimes the honest answer is simpler. If an off-the-shelf tool does 90% of what you need, buy it and configure it. If you need a company website, you need a good web agency, not a CTO. A fractional CTO who tells you otherwise is selling hours.
Fractional CTO vs full-time CTO: a quick decision table
| Your situation | Fractional CTO | Full-time CTO |
|---|---|---|
| Building your first product | Best fit | Usually premature |
| Choosing between agencies, or build vs buy | Best fit | Overkill |
| Rescuing a stalled project | Fast to start | Slow to hire |
| Technology is your core product | Bridge to a hire | Best fit |
| Engineering team of 15+ | Not enough time | Best fit |
| Budget under ₹30 lakh a year for tech leadership | Fits | Hard to attract the right person |
Reev Travels shows how this plays out. Reev, a Bangalore-based corporate travel company, was handling 350–500 bookings a month over email, WhatsApp and spreadsheets, and adding people only added mistakes.
The obvious move was to buy a booking tool. As their part-time CTO, I judged that off-the-shelf tools would hit their limits within a year and the team would drift back to spreadsheets. So we built, with a backend engineer, a frontend engineer, a DevOps consultant and a freelance QA tester.
About a year later Reev had a multi-tenant platform for booking, billing and reporting, and the knowledge stayed inside the business. They didn't need a full-time CTO for that. They needed one good build-vs-buy decision and someone to lead the team. See how three engineers built a complete platform in a year.
How to choose a fractional CTO: 8 questions to ask
A LinkedIn title proves very little. Ask these before you sign:
- What have you taken from idea to launch? Ask for named products you can download or visit, not just "led teams".
- What was your role on each one? Advisor, CTO, or the person who actually made the calls?
- Do you also sell development? How do you handle that conflict? This one matters. I'll answer it for myself below.
- Who will own the code, servers, domains and app store accounts? The only acceptable answer is "you".
- How many hours a week will I get, and what happens when there's a crisis?
- How will you report progress to me? You should get business language: dates, costs, risks.
- What does handover look like, and when do we stop needing you?
- Can I speak to two past clients? References from business owners, not just engineers.
On question 3, here's my own answer. Reset, my studio, also builds products.
Most of my engagements start with an independent recommendation. If another vendor or your own team is the better fit, I'll say so and help you work with them. Some clients choose Reset because they want one accountable partner. Either way, you own the code, and that's in the contract.
A note on AI
Every product conversation now includes AI. Part of the job is telling you where AI makes your product better, cheaper to run or faster to build, and where it's an expensive distraction. If an AI proposal is what's prompting the search, start with my buyer's guide on whether you should build an AI agent. It covers costs in India and the questions to ask.
Frequently asked questions
Does a fractional CTO write code?
Usually not much. The value is in the decisions: architecture, vendor choice, code reviews and technical direction. The build is done by your team, an agency or a studio you choose together.
How many hours a week does a fractional CTO work?
Typically 1–2 days a week, or about 8–16 hours. It's often more at the start of a build or during a rescue, and less once things are running.
How long does a fractional CTO engagement last?
A scoping exercise takes 3–4 weeks. A full engagement usually runs 6–12 months, until the product is live and you have a team or vendor who can carry it.
Can a fractional CTO work with my existing agency?
Yes, and that's common. The CTO reviews the agency's work, makes the technical calls and tells you plainly whether to fix the relationship, restructure it or change course.
Can a fractional CTO become full-time?
Sometimes. At RightLife, I started as a technology consultant for four months and then became the full-time CTO for eight. Just as often, the part-time CTO helps you hire your first full-time technology leader.
Who owns the code when a fractional CTO is involved?
You do. Making sure of that, starting with the contract, is one of the first jobs on the list.
Is a fractional CTO only for startups?
No. Some of the best uses are in established businesses (manufacturing, distribution, travel, real estate, healthcare) building their first platform, internal system or app.
