The Context

A national initiative for financial inclusion

Hustler Fund is a Government of Kenya initiative designed to improve financial inclusion by providing affordable credit and micro-pension products to underserved citizens and MSMEs.

The initiative targets Kenyans at the bottom of the economic pyramid, representing:

  • 80%+ of the workforce
  • 33% of Kenya's GDP

The objective was to:

  • Promote a culture of saving
  • Improve access to affordable credit
  • Reduce dependence on predatory lenders
  • Cushion citizens against economic shocks
  • Support business growth

The product launched with:

  • Personal Loan Product (PLP) — Launched on 30 November 2022
  • Micro Enterprise Loan (Biashara Loan) — Launched on 2 February 2023
Why This Project Mattered

More than a loan product

This wasn't simply a loan product. It was a national-scale initiative designed to expand financial access to millions of Kenyans who have historically been underserved by traditional financial institutions.

Designing for this audience required balancing:

  • Simplicity
  • Trust
  • Accessibility
  • Financial literacy
  • Speed to market
The Challenge

Designing at speed under constant change

The project had aggressive delivery timelines. Requirements evolved rapidly as stakeholders refined the product vision and policy requirements.

We needed to:

  • Design at speed
  • Align multiple stakeholders
  • Iterate continuously
  • Maintain simplicity despite increasing complexity
How might we deliver an intuitive financial experience while adapting to constant change?

The Design Sprint

A sprint-based approach to meet delivery timelines

1. Stakeholder Alignment

Aligned on product vision, objectives, business goals, user needs and success metrics — critical as requirements evolved.

2. Defining User Stories

Translated requirements into user stories covering opt-in, loan limits, requests, repayments, balances, savings and beneficiaries.

3. Rapid Ideation

Explored multiple concepts through design workshops, sketching sessions and collaborative reviews before converging.

4. Rapid Prototyping

Transformed concepts into low-fidelity and high-fidelity prototypes, with each review cycle informing the next iteration.

Understanding the Users

Designing for individuals and small business owners

The target audience included individuals and small business owners with limited access to affordable financial products.

User Stories

Translating needs into the experience

  • As a user, I want to opt into and access the services intuitively.
  • As a user, I want to check my loan limit so I know how much I am eligible for.
  • As a user, I want to request a loan by providing the amount so it can be approved.
  • As a user, I want to check my loan balance so I can keep track of what I owe.
  • As a user, I want to repay my loan so I can clear my debt and maintain a good credit score.
  • As a user, I want to view my loan transaction history so I can see my repayment progress.
  • As a user, I want 5% of my loan transferred to savings — 3% to pension and 2% to a savings account — so I can build a culture of saving.
  • As a user, I want to add emergency contacts and beneficiaries of my assets.
Design Principles

Three principles guided every decision

Accessible

Financial services should be easy to understand regardless of financial literacy.

Simple

Reduce complexity and guide users confidently through every step.

Empowering

Encourage healthier financial habits that go beyond borrowing.

Key Learnings

What this project taught me

  • Alignment accelerates delivery — moving fast requires clarity and shared understanding across teams.
  • Design is a continuous conversation — the strongest solutions emerged through constant feedback and iteration.
  • Simplicity creates inclusion — financial products only create impact when they're accessible to the people who need them most.
Reflection

Designing at speed is about making the right decisions quickly

This project reinforced that designing at speed isn't about skipping process. It's about making the right decisions quickly, collaborating effectively, and continuously adapting as new information emerges.

In fast-moving environments, alignment becomes just as important as design craft.
