Fractional CTO for Startups
Fractional CTO for startups — part-time senior technical leadership for founders: 0→1 product builds, the right stack, first hires, and scaling architecture.
A fractional CTO for startups is the senior technical leader an early-stage founder gets before they can justify a full-time executive — someone who has built products from zero, made the expensive mistakes already, and can steer yours around them. I’m Kuldeep Pisda, a former startup CTO and co-founder. For 6+ years I’ve taken products from a blank repo to something real users depend on, and now I do that part-time for seed and early-stage founders who need one strong technical head in the room, not a whole department.
What a fractional CTO does for a startup
Most early technical damage is invisible until it’s expensive: the wrong database, a framework nobody can hire for, a build the outsourced team can walk away from. My job is to keep those decisions boring, defensible, and reversible while you’re still small.
- Architecture & stack — pick tools that are proven, hireable, and cheap to run, and design the boundaries so v1 doesn’t become the thing that has to be thrown away at v3. Boring and scalable beats clever and fragile every time.
- First hires — write the specs, run the technical interviews, and set what “done” means, so your first engineers raise the bar instead of baking in habits you’ll spend two years unlearning.
- Delivery — stand up CI/CD, code review, testing, and a release process from day one, so shipping stays fast and safe as the team and the codebase grow.
- Technical due diligence — for your own fundraise, a codebase you inherited, or a vendor you can’t independently judge: I’ll tell you plainly where the risk sits and what it costs to fix.
- Scaling architecture — knowing when to optimise, when to re-architect, and when to leave it alone, driven by query plans and profiles instead of hunches.
I stay hands-on. I still write and review code, so the guidance is grounded in what your team is actually shipping — not a slide deck from someone who stopped building years ago.
Why founders bring me in
I’ve sat in the founder’s chair and the CTO’s, so I know both the technical call and the runway pressure behind it. I led a ~6-person engineering team, owned the roadmap end to end, and set the standards they built to. On the delivery side I scaled a platform past 30,000 users on a lean budget, and I’ve built products 0→1 across OTT/LMS streaming, AI, and SaaS — the messy early stage where the spec changes weekly and the architecture has to survive it. I took products through SOC 2 Type 1 and Type 2 and did the founding-SRE work to stand up the infrastructure underneath, so compliance and reliability aren’t afterthoughts.
My hands-on stack is deep where it counts: Django/DRF and FastAPI, PostgreSQL, Celery, AWS, and Terraform. On the AI side I’ve shipped multi-LLM systems, RAG and semantic search, and voice/SMS agents in production — the difference between a demo and something that holds up under real load. I maintain django-rls, an open-source PostgreSQL row-level-security library, and I speak at DjangoCon US, DjangoCon Europe, and EuroPython, so the standards I bring come from the wider community, not one company’s habits. The case studies walk through the real trade-offs.
How engagements work
Fractional means a fixed, dependable slice of my week on retainer — a partner who holds your context from one week to the next, not a stranger you re-brief every call. Most founders start around one to two days a week (8–16 hours), scaling up around a fundraise, a launch, or a hard scaling push, and down once the foundations are steady. If you mainly need a senior sounding board, a lighter advisory cadence works too. Remote, on IST, and used to overlapping with US, EU, and India founders.
FAQ
What is a fractional CTO? A senior engineering leader who works part-time for your company instead of joining full-time. You get CTO-level strategy, hiring, and technical judgement without a full-time executive salary or the wait to find one.
When does a startup need a fractional CTO? When technical decisions have outgrown the founder — first engineering hires, a 0→1 build, a re-architecture, a compliance push, or investor due diligence. If a wrong call now would be expensive to unwind later, that’s the moment.
How does the cost compare to a full-time CTO? Far less. It’s a monthly retainer scoped to the hours you actually need — predictable, and easy to scale up or down — versus a senior salary plus equity for a role you may not need full-time yet.
Do you take equity or cash? Primarily a cash retainer, since that keeps the engagement clean and flexible. For the right early-stage story I’m open to a modest equity component alongside it — happy to talk through what fits your stage.
Will you actually write code? Yes. I stay hands-on — writing and reviewing code, unblocking the team, and setting patterns by example — so the architecture advice is real, not theoretical.
