Who Hari PK works with

Business Owners & Founders

For people who have a business challenge, a product idea or a growth ambition and need help deciding what to do next.

CEOs & Leadership Teams

For organisations looking to sharpen positioning, align marketing with business goals, improve go-to-market execution or identify practical AI opportunities.

Product Teams & Aspiring Builders

For teams looking for stronger strategy, better execution, improved lead-to-revenue processes or practical AI-assisted workflows.

Services: three pillars, one connected path

Define the right product, take it to market, and use AI to make the whole engine work smarter.

Product Building

Turn ideas and business problems into clearly defined products and practical solutions.

Marketing & Go-to-Market

Build a clear path from product value to market adoption and growth.

AI for Business & Growth

Apply AI where it can solve real business problems and improve how work gets done.

Approach to AI for business: start with the problem, then add AI

Not every problem needs AI. Sometimes conventional automation, a product change or a simpler process improvement is the right answer.

  1. Understand the problem — the people affected and the outcome that matters
  2. Map the process — how the work happens today
  3. Identify the AI opportunity — where AI genuinely helps
  4. Design the solution — inputs, steps, rules, handoffs
  5. Build what is needed — the simplest solution that works
  6. Keep humans in the loop — people review and decide
  7. Measure the outcome — business value, not activity

How Hari PK works

  1. Understand — Learn about the business, customers, challenges, and objectives.
  2. Define — Identify the opportunity, clarify priorities, and determine what matters most.
  3. Build & Execute — Turn strategy into a product, marketing initiative, or practical AI workflow.
  4. Learn & Improve — Evaluate what works and improve the next iteration.

Ways to work together

Advise — Your team. My thinking.

I work alongside your existing team to provide strategic direction, product thinking, marketing and growth advice, AI opportunity assessment and execution guidance.

Best suited for: Businesses with existing teams that need experienced strategic input.

Build together — Your team. My extended team.

I collaborate with your people and bring in relevant specialists when required to deliver an agreed initiative across product, brand, marketing, automation or growth.

Best suited for: Businesses that have internal ownership but need additional expertise or execution capability.

Build & deliver — One brief. End-to-end execution.

I lead a defined project from discovery and planning through implementation and handover, with specialist support where the project requires it.

Best suited for: Founders and businesses that want a defined outcome without managing every execution detail themselves.

Team composition, individual responsibilities, third-party costs, deliverables and ownership are agreed before work begins.

Commercial models

Project-based
Defined scope, deliverables, milestones and an agreed fee. Suitable for product discovery, MVP planning, brand and go-to-market projects, AI workflow builds and specific growth initiatives.
Monthly retainer
Ongoing strategic or execution support with agreed scope and capacity, for businesses that need consistent involvement rather than a one-off project.
Hourly / time-based
Consulting sessions, focused working sessions and flexible advisory support. Hourly billing may be appropriate for international clients.

The right model depends on the work, not a predefined package. Commercial terms are agreed before work begins. Remote engagements are available for businesses outside India.

Experience

Built
I co-founded Big Foxx Branding & Technology in 2012 as a first-generation entrepreneur. Over more than a decade, I helped build the company across 150+ brands and 11+ sectors before its exit following a merger with a Hyderabad-based company.
Grew
At Everrenew, I led Branding & Corporate Communications during a period of significant business growth, as the company’s turnover increased from ₹500 crore to ₹2,500 crore. I later moved on following the company’s subsequent acquisition by a leading renewable energy company.
Shared
I have conducted 300+ workshops and sessions at the intersection of business, marketing, technology, and growth, sharing practical perspectives with entrepreneurs, professionals, and students.
Today
I focus on helping businesses move beyond simply talking about AI. The opportunity is to identify meaningful problems, make better decisions, and build practical products and workflows that solve them.

Frequently asked questions

Who is Build with HPK for?

I work with founders, business owners, CEOs, product teams and marketing leaders who need help turning a business problem or opportunity into a clear plan and practical execution. The right engagement depends on the challenge, team and desired outcome.

What can I work with HPK on?

Engagements may cover product discovery and MVP planning, brand and positioning, go-to-market strategy, marketing and growth systems, and practical AI workflows. I start with the business problem and recommend the relevant scope rather than pushing a fixed package.

Do you only consult, or can you execute too?

Both. I can advise your existing team, work alongside them with additional specialist support, or lead an agreed project through implementation and handover. The delivery model is defined before work begins.

Do you have an in-house team?

My involvement is tailored to the engagement. I can work directly with your team and bring in relevant specialists when needed. Team composition, responsibilities, third-party costs and deliverables are agreed transparently.

How do you charge?

Depending on the work, engagements can be project-based, monthly retainer-based or hourly. Fees depend on scope, complexity, duration and delivery requirements. International consulting can be billed hourly where appropriate. You receive the agreed commercial terms before work starts.

Do you work with businesses outside India?

Yes. Remote engagements can be considered across geographies. Scope, working hours, communication, currency, payment terms and any specialist support are agreed based on the project.

Can you work with our existing marketing, product or technology team?

Yes. I can collaborate with existing teams, help establish priorities and workflows, and support execution without automatically replacing your current partners or people.

Can you help us use AI if we don’t know where to start?

Yes. We begin by understanding the process, friction points and business outcome. We then assess whether AI, conventional automation, a product change or a simpler process improvement is the right answer. Not every problem needs AI.

How do we get started?

Share the business challenge, what you want to achieve, your timeline and the team or resources already available. We can then assess fit, define a practical next step and agree on scope and commercials before committing.

Do you guarantee business results?

No responsible partner can guarantee outcomes that depend on customers, markets, execution and other variables outside their control. I commit to clear scope, transparent thinking and agreed deliverables, with success measures defined where appropriate.
