Overall verdict

  • LetSorted appears to be a UK-based property/letting management service, but I do not have verified, up-to-date information about this specific company to confirm its reputation, service quality, or customer satisfaction levels. I'd recommend independently verifying through official reviews before forming a judgment.

Why this product is good

  • Unable to confirm specific service features without verified current data
  • Cannot validate customer reviews or ratings from reliable sources
  • No access to real-time company registration or regulatory compliance information
  • Recommend checking Trustpilot, Google Reviews, or Companies House for verified details

Recommended for

  • Users should conduct independent research before relying on this assessment
  • Check official regulatory bodies like the Property Ombudsman or ARLA Propertymark for accreditation
  • Verify through direct customer testimonials and third-party review platforms

Questions & Answers

As answered by people managing JSON Formatter & Validator and LetSorted.

What makes your product unique?

LetSorted's answer:

LetSorted is the only property management tool built specifically for UK self-managing landlords that automatically builds a court-ready evidence trail as you manage. Every inspection is signed by both parties, every maintenance request is timestamped, every rent payment is logged — so if a tenancy goes wrong, your evidence is already there.

Why should a person choose your product over its competitors?

LetSorted's answer:

Most UK landlord software focuses on accounting and rent tracking. LetSorted covers the full tenancy lifecycle — from AI-powered tenant screening to move-in inspections, periodic checks, maintenance logs, and a one-click Dispute Evidence Pack. It's also the only tool built around the Renters' Rights Act 2025, with RRA-compliant contracts and Section 8 evidence support built in.

How would you describe the primary audience of your product?

LetSorted's answer:

UK self-managing landlords with 1–5 properties who currently juggle spreadsheets, folders, and WhatsApp. They don't want to hire a letting agent, but they do want to stay compliant and protected — especially after Section 21 abolition.

What's the story behind your product?

LetSorted's answer:

The founder moved to the UK in 2022 and spent two weeks navigating paper forms and photocopied contracts just to rent a house. Three years later, researching buy-to-let investment, he couldn't find software that would protect a small landlord under the new Renters' Rights Act. So he built it — first for himself, then for everyone.

Which are the primary technologies used for building your product?

LetSorted's answer:

Next.js, TypeScript, PostgreSQL (Supabase), Prisma, Stripe, Resend, Claude AI (Anthropic), pdf-lib, Tailwind CSS. Hosted on Vercel with EU-based data storage.

Who are some of the biggest customers of your product?

LetSorted's answer:

Early stage, currently onboarding first users via Product Hunt launch.
