I lead product that ships

Discovery, roadmap, delivery, and the team that builds it. Judgment you can touch, from first interview to launched revenue.

Kill criteria first. Three bets fail the bar this week. They go.

Locked. Roadmap down to 5 bets.

AI handles the grunt work

Research, analysis, documentation: AI. Decisions, alignment, relationships: me. Output looks like a department, not a solo consultant.

Strategy with owners and dates

Where to play, how to win, and how it shows up in the product. Then I stay until it ships.

Field notes

How I think about the work.

Q3 2026 · Roadmaps

I kill criteria first, features second

Every roadmap starts with what we are willing to stop. If you cannot kill a feature when the data says stop, you have a wish list with deadlines.

Q3 2026 · Fractional

You are buying my judgment, not my hours

A full-time CPO costs £180K+ and takes months to ramp. Pattern recognition across 40+ products is the product.

Q3 2026 · Execution

I do not confuse the deck with the strategy

Strategy is the next three decisions you make. A 90-day execution plan ships in week one.

Discuss this over a call

I operate first. I advise second.

I am Sree Durairaj. 10+ years shipping products, from zero to revenue and from idea to scale.

Based in Leicester, working remotely across the UK and Europe. Rooms from first pitch to board calls taught me what actually moves a startup forward.

I work fractionally because focused leadership beats full-time theatre. You need someone who has shipped, not someone reading from a playbook.

10+ Years shipping product
£50M+ Revenue influenced

Is this for you?

Good fit if you

  • Run a pre-seed, seed, or idea-stage startup
  • Want a senior operator, not a consultant
  • Have builders but no one owning the roadmap
  • Need board-ready strategy you do not have time to write
  • Need someone who ships, not only advises

Not a fit if you

  • Need a full-time employee
  • Want someone only to hire your team
  • Want a deck delivered and a quiet exit
  • Are shopping for cheap labour, not judgment
FAQ

Straight answers.

What is the difference between a fractional CPO and a fractional CSO?

A CPO owns the roadmap, product experience, and what ships. A CSO owns positioning, growth strategy, and market expansion. You pick the seat, or I blend both.

How does the 30-day trial work?

We lock scope on the first call. I execute for 30 days, then we review. If it is not working, you walk. No lock-in.

Can I switch between CPO and CSO mid-engagement?

Yes. I shift focus as needs change, and we re-align on the next 90-day outcome.

What does AI-amplified mean in practice?

I use AI for research, competitive analysis, and pattern recognition so you get executive-grade output faster. It amplifies my judgment. It does not replace it.

Do you work with non-UK companies?

Yes. Based in Leicester, working remotely across Europe and beyond. Async keeps things moving between calls.

I am pre-revenue. Can I still work with you?

Yes. Most founders I work with are pre-revenue. The Catalyst package at £499 a month is built for this: advisory, product strategy, and roadmap direction without embedded days.

What if I do not have product-market fit yet?

That is where I add the most value. Validate the problem, shape the MVP, and write the first product strategy together.

Do you support seed raises?

Yes. Product narrative, investor-ready roadmaps, and the deck that tells the story. Many founders I work with are 3–6 months from a raise.

Ready for me to fill the seat?

25 minutes. We map the 90-day outcome, lock scope, and pick the engagement.

Prefer to write first?
