Hands-on fractional CTO
that ships.
Product, engineering, delivery, and fundraising — owned end-to-end. I write production code, ship the right features, run the team, and report to the board. Not just strategy slides.

Scaling engineering is expensive,
slow, and easy to get wrong.
Most founders aren't ready for a full-time CTO — but they pay the price of not having one every single week.
Your first five hires define your velocity for the next two years. Most founders hire the wrong profile and pay for it in year one.
What worked for 100 users breaks at 10,000. By the time you see the cracks, rewrites cost you six months and a funding round.
You need someone who can speak to investors, due-diligence your stack, and own technical decisions — without a £200k full-time salary.
Advisory and hands-on. One operator, nine disciplines.
Pick one or combine. Every engagement starts with a short assessment so we're aligned on the outcomes we're going after before anything else.
Fractional CTO Leadership
Embedded as your part-time CTO. Own technical direction, unblock the team, and report into the board.
- Weekly 1:1s with engineering leads
- Architecture & roadmap ownership
- Board-level technical reporting
Fundraising & Deal Support
Pre-seed to seed fundraising from the founder's side of the table. Legal, financial, and technical workstreams run in parallel — so you close faster and cleaner.
- SeedLegals contracts, cap table, term sheets
- Financial modelling & runway planning
- Investor DD: technical, product, founder
- Deal negotiation & closing support
Product Management
Ship the right features at the right time. Roadmaps tied to real user outcomes, not founder instinct.
- Discovery, prioritisation, roadmap
- Opportunity solution trees
- OKRs tied to product outcomes
Full-Stack Engineering
Hands-on code, not just strategy. I ship features, unblock PRs, and pair with your team when it matters.
- TypeScript, Node, Python, Java
- React, Next.js, Angular frontends
- APIs, queues, event-driven systems
Architecture & DevOps
Design systems that survive the next order of magnitude. Set up the infra, CI/CD, and cost controls once — properly.
- AWS, Azure, GCP, Kubernetes
- CI/CD, IaC, observability
- Cloud cost & reliability reviews
Security Engineering
Ship secure by default. Threat modelling, application security, and the groundwork for SOC 2 and ISO 27001.
- Threat modelling & secure SDLC
- Authn/authz, secrets, data handling
- SOC 2 / ISO 27001 readiness
AI & Machine Learning
From LLM-powered features to production ML pipelines. Practical AI that ships — not slideware.
- LLM integration, RAG, agents
- Model selection & evaluation
- ML pipelines & MLOps
Delivery & Engineering Ops
Run the engineering department. Agile delivery, sprint rhythm, and the metrics that show you're actually shipping.
- Scrum / Kanban / Shape Up
- Delivery metrics & dashboards
- Rituals, retros, and incident response
Team, Hiring & Due Diligence
Hire the right first five engineers — or run the technical DD before a round, acquisition, or rebuild.
- Interview loops & scorecards
- Engineering ladder & comp bands
- Pre-investment technical DD (5–7 days)
A four-step engagement — designed to de-risk every week.
30-minute call. We scope the problem, stage, and fit. No pitch — just an honest read on whether I can help.
Short assessment sprint. I meet the team, read the code, and deliver a written plan with the outcomes we're going after and how we get there.
Ongoing fractional engagement — typically 1–2 days per week. Aligned on outcomes, not hours.
Quarterly reviews tied to measurable goals: shipping velocity, hiring targets, reliability, fundraising milestones.
Bidwise AI
Pre-seed funded startup · Fractional CTO · 2025 – Present
Helping a pre-seed AI startup go from prototype to production — setting technical direction, owning architecture, and building the founding engineering team.
Founder-led technical team needed a senior counterparty to own architecture decisions, set the hiring bar, and support investor conversations ahead of seed round.
- Set technical strategy and 12-month roadmap to seed milestone
- Architected production-grade AI pipeline built for scale from day one
- Designed the engineering hiring plan and ran technical interviews
- Acted as technical counterparty for investors and board
- Ran fundraising mechanics with founders: SeedLegals contracts, investor DD, deal negotiation
- Built financial model and runway plan used in investor conversations
A decade of shipping engineering leadership.

Meet Mayur.
I spent a decade building and leading engineering teams — from pre-seed startups finding product-market fit to the UK government's £1Bn digital transformation programme.
I'm a hands-on CTO. I write production Java, TypeScript, Python, Node and Solidity. I design cloud infrastructure, bake in security, and ship AI/ML features end-to-end. I've hired, fired, and mentored engineers, and sat in board rooms explaining architecture to non-technical founders and investors.
Now I bring that senior engineering leadership to founders who need it — without the full-time cost or the two-month hiring loop. I don't just advise. I build.
Frequently asked.
How many clients do you take on at once?
Deliberately few. I cap concurrent engagements at 3 so every client gets real attention — not someone splitting their calendar eight ways. There are 2 slots open this quarter. Once they're filled, the next opening is typically 60–90 days out, so if you're weighing a call, book it now rather than later.
How does a fractional CTO engagement work?
I embed with your team 1–2 days per week on a fixed monthly retainer. You get senior technical leadership for a fraction of a full-time CTO's cost — typically £80k–150k saved annually.
What stage companies do you work with?
Pre-seed to Series A. Usually 2–15 engineers. If you're post-Series B and need someone full-time, I'll tell you on the discovery call.
Do you publish pricing?
No. Pricing depends on scope, stage, and hours per week. The discovery call is free and I'll quote on the follow-up.
Are you remote or on-site?
Remote-first, UK-based. I travel on-site for workshops, kickoffs, board meetings, critical hires, and any other moment where being in the room actually matters. Expenses billed at cost.
Who owns the IP of work you produce?
You do. Standard work-for-hire terms in every engagement contract — no ambiguity, no IP carve-outs.
What's the notice period?
30 days either side after the initial 2-week assessment. No long tie-ins.
Can you do one-off technical due diligence?
Yes. 5–7 day turnaround, fixed fee, written report ready for investment committee.
Do you help founders raise?
Yes — I've run full pre-seed fundraising with founders from the inside. Contracts (SeedLegals), financial modelling, investor DD, and deal negotiation. Not as a placement agent or introducer: as the technical co-founder-equivalent who owns the workstream alongside you.
Ready to scale your engineering?
Book a 30-minute discovery call. If we're not a fit, I'll tell you on the call — and point you toward someone who is.
