Building is easier.
Building the right thing is still hard.

AI makes research, prototyping, content creation, and automation easier.

But businesses still need to understand customers, identify opportunities, make product decisions, communicate value, reach the right market, and create sustainable growth.

That is where business thinking, product building, marketing, and practical AI need to work together.

WHO SHOULD BUILD WITH HPK?

Good work starts with the right thinking. And the right partner to build it with you.

Whether you need strategic clarity, an experienced partner alongside your team, or someone to take a defined initiative from idea to execution, let’s start with the business problem.

    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.

  • 02

    CEOs & Leadership Teams

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

  • 03

    Product Teams & Aspiring Builders

    For people validating ideas, prioritising features, shaping an MVP or turning a product concept into something customers can use.

  • 04

WHAT I DO

Three pillars. One connected path.

Each pillar feeds the next: define the right product, take it to market, and use AI to make the whole engine work smarter.

MY APPROACH TO AI FOR BUSINESS

Start with the problem.
Then add AI.

I don't start by asking which AI tool to use. I start by understanding the problem, the people affected, and the outcome that matters.

WAYS TO WORK TOGETHER

The right involvement. For the right challenge.

Some businesses need strategic direction. Others need additional execution capability. Some need a partner to take a defined initiative from idea to delivery.

I can work in the way that best fits the problem, your team and the outcome you want to achieve.

  1. MODEL 01

    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 FORBusinesses with existing teams that need experienced strategic input.

  2. MODEL 02

    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 FORBusinesses that have internal ownership but need additional expertise or execution capability.

  3. MODEL 03

    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 FORFounders 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

Flexible engagements. Clear commercials.

Every engagement starts with a conversation about the business problem, the desired outcome and the level of involvement required.

The commercial model is based on the scope, complexity, duration and delivery requirements.

  • 01

    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.

  • 02

    Monthly retainer

    Ongoing strategic or execution support with agreed scope and capacity.

    Suitable for businesses that need consistent involvement rather than a one-off project.

  • 03

    Hourly / time-based

    Consulting sessions, focused working sessions and flexible advisory support. Hourly billing may be appropriate for international clients.

    Suitable for expert consultations, focused problem-solving and time-based advisory engagements.

The right model depends on the work—not a predefined package.

Commercial terms are agreed before work begins.
