Harman AJ Ltd

Independent software · England & Wales

We build our own products, and we stand behind them.

Harman AJ Ltd is an independent software company registered in England and Wales. We design and build our own software: no agency work, no outsourcing, and nothing shipped unless we genuinely believe it is useful.

About us

Independent, focused, accountable.

Harman AJ Ltd exists to build software we genuinely believe to be useful. We are not a consultancy or an agency: every product we ship is one we own, support and answer for ourselves, from the first line of code onwards.

Focus is a deliberate choice. Every product gets the same close attention: the security of the infrastructure, the clarity of the interface, and the privacy of the people who trust us with their data. When something needs fixing, the people who built it fix it.

Our first product launched in 2026, and it is the start of a portfolio, not the whole of it. Everything we build follows the same pattern: useful first, careful with data by design, and improved steadily in response to how people actually use it.

How we work

Four principles we hold ourselves to.

01

Privacy by design

We take the least access a product needs to do its job, and we enforce that in code, checked on every build, not just promised in the marketing.

02

Built in-house

Our software is designed, built and supported by us, not outsourced. Questions are answered by the people who wrote the code, so problems get fixed at the source.

03

Hosted in the EU

The products we host run on EU infrastructure, with credentials encrypted at rest and verified backups held off the production servers.

04

Security as routine

Vulnerability scanning and security testing are part of normal operations, done regularly rather than once before launch.

Portfolio

What we've built.

The Sortfully website: a cluttered inbox shown being filed into folders and coloured tags by the organisation that sent each message.

Sortfully

Live

Sortfully organises Outlook and Microsoft 365 inboxes automatically. It files every message into a folder, or a coloured category, by the organisation that sent it, so mail groups itself by who is writing instead of piling up in arrival order.

It is built around a strict privacy guarantee: Sortfully never reads message bodies or attachments. By default it also waits until a message has been read before moving it, so nothing disappears before it has been seen.

  • Works with Outlook and Microsoft 365 via the Microsoft Graph API
  • Files into folders or coloured categories, per mailbox
  • Never reads message bodies or attachments
  • Clears historical backlog safely, leaving recent mail alone
  • Plans for individuals and teams
