On the founder

A practice owner who builds the tools.

Mehmood Rajoka arrived in the UK in 2011. By 2016 he'd built an eBay business to £1M a year, for someone else. So he started again, unpaid, as a bookkeeper at RR Accountants in Birmingham. Six years later he bought in and became a 50% co-owner.

Along the way they took the firm digital. Every tool they couldn't find, he built. That became Rajoka, a group of UK businesses that includes software for practices: compliance, bookkeeping and practice management. In 2025 he was named Young Entrepreneur of the Year.

Ten years inside a practice taught him this: AI won't replace good firms. It will expose the badly run ones.

The journey

From a village in Pakistan to building an institutional portfolio.

  1. Origin

    Village roots in Pakistan

    Born into a rural community where ambition came from observing a different world. Early exposure through an elite college shifted what was possible.

  2. 2011

    Migration to the United Kingdom

    Arrived after an initial visa rejection then approval. Survived early years through IT support work while teaching himself ecommerce.

  3. 2012—2016

    The eBay years

    Built an eBay business to £1M turnover — for an employer, not himself. The lesson that shaped everything after: never build value you don't own.

  4. 2016

    The accounting pivot

    Stepped away from IT and joined RR Accountants unpaid. Started as a bookkeeper. Set out to learn the discipline that runs every business.

  5. 2022

    Bought into RR Accountants

    Became 50% co-owner. Began re-engineering the firm with systems, automation, and modern client infrastructure.

  6. 2023

    Bryxo founded

    Launched as the operating arm for founder back-office work — the first deliberate building block of the Rajoka portfolio.

  7. 2025

    Young Entrepreneur of the Year

    Recognised for sustained operator performance, system-led growth, and contribution to founders across the region.

  8. 2026

    Rajoka formalised

    The parent portfolio brand is established — a house of operating companies across compliance, operations, growth, and investment.

  9. March 2026

    Mantle Partners

    Launched Mantle Partners as the acquisition arm of Rajoka. A long-horizon growth-by-acquisition strategy: acquire, operate, and compound proven UK businesses with the goal of scaling the Rajoka portfolio toward £100M. Capital deployed with operator discipline, not spreadsheet optimism.

What I'm building

Rajoka. A portfolio of operating companies.

Rajoka is the parent brand and institutional umbrella behind a focused house of operating companies. It helps businesses start, run, and grow — across four operating layers.

Layer 041 company

Investment

Capital deployed with operator discipline.

Each company stays primary in its own market. Rajoka is the standards layer behind them — not a service marketplace, not a software platform.

Operating philosophy

Six principles that shape how I build.

I

Resourcefulness over resources

Constraints sharpen judgment. The best operators do more with less for longer than feels reasonable.

II

Systems create leverage

Every repeat decision belongs in a system. Personal effort scales linearly. Systems compound.

III

Focus beats fragmentation

Each company in the portfolio has one job. Clarity of purpose protects against operational drift.

IV

Build with structure

Governance, standards, and infrastructure are not bureaucracy — they are how good companies become durable ones.

V

Legacy over short-term noise

Decisions are made on a ten-year horizon. The market rewards patience differently from social platforms.

VI

Show the work

Documenting the journey sharpens the operating. The work is the brand, and the record is the proof.
