About TenderSeal

Help small businesses win the public contracts they're qualified for, not just the ones they have time to bid for.

Our story

Why did we start TenderSeal?

Shaped by 50+ conversations with SMEs, bid writers and advisors, with testers in the UK, Ireland and the Netherlands.

TenderSeal started when four friends out of college set out to solve one problem with AI, and solve it properly. Rather than guess what that problem was, we asked business owners: what would you want AI to fix?

One answer stood out: “We hate doing tenders, but it’s half our revenue. Can’t you make something to automate it?”

We’ve worked on that ever since. Every version of TenderSeal has been tested by people who bid for contracts, then rebuilt around what they told us. Along the way, Dr Simon Raybould, who has run his consultancy Aware Plus since 2008 and writes his own bids, became our advisor. With his feedback, getting from tender to first draft went from days to about an hour.

Our rule hasn’t changed: don’t assume what the solution should be. Ask the people who’ll use it. What our beta users ask for is what we build next.

Mission and vision

What are we working towards?

Mission

Help small businesses win the public contracts they're qualified for, not just the ones they have time to bid for.

Vision

A public sector where the best supplier wins, not the biggest bid team.

Values

What do we hold to?

  1. 01

    Ask, don't assume

    We build what bidders tell us they need.

  2. 02

    Only what's true

    No invented claims, in our bids or our marketing.

  3. 03

    Your documents stay yours

    Encrypted, stored in the UK and the Netherlands, and never used to train AI.

  4. 04

    AI where it saves hours, not as a buzzword

    It takes the reading and the first draft off you. The judgement stays yours.
