85%
of UK SMEs rebuild their tender responses from scratch every time — compounding time cost with no reusable library.
more time per tender when there is no structured bid library, case study engine or evidence vault behind each answer.
£300bn
UK annual public sector spend. What's limiting you isn't what you can deliver — it's how you prove it on the page.
the problem

three reasons UK SMEs lose tenders
they should have won.

01
no case study library
Project evidence is scattered across old submissions, emails and spreadsheets. Every new ITT means hunting for the same material — or drafting without it and hoping the evaluator doesn't notice the generic answers.
"We had the case studies. We just couldn't pull them together before the deadline."
02
writing for the response, not the evaluator
Most SMEs write tenders that describe what they do. Public sector evaluators score what you will deliver, how it will be governed and what evidence proves you've done it before. Generic writing scores Adequate at best.
"Our technical approach was strong. The panel just couldn't find the evidence to support it."
03
starting from scratch every time
Without a reusable bid library — case studies, methodologies, social value evidence, Carbon Reduction Plan content — every ITT costs the same. No compounding, no learning loop. The win rate stays flat.
"We submitted ten tenders last year. Won three. The process wore the team out more than the losses did."

what makes it different

what if every tender was built the way evaluators actually score?

Build My Bid Manager is not an AI writing tool. It is a complete UK bid operating system — one that builds a reusable library from your own evidence, runs every draft through an evaluator critique, and gets stronger after every tender.

get the system — £600 →
  • 01
    company brain & case study engine
    Verified case studies, evidence vault and company profile — built from your own documents, never invented. Every answer draws from real proof, not generic language.
  • 02
    evaluator scoring at every draft
    Every answer scored out of 50 against the evaluation criteria before you accept it. Answers below 35/50 must be rewritten. You see the panel's view before they do.
  • 03
    social value & carbon built in
    PPN 002-aligned social value library, Carbon Reduction Plan evidence and ESG commitment checks — embedded in the system, not bolted on afterwards.
  • 04
    no invented claims — ever
    Every prompt instructs the AI to write [EVIDENCE NEEDED] when evidence is missing. Never invent a case study outcome, KPI or accreditation. You cannot submit what you cannot support.
  • 05
    post-bid learning loop
    After every submission: extract Grade A content, update the evidence vault, log the outcome. Each bid makes the next one faster, stronger and more likely to win.
zero friction. zero extra cost.

it runs inside the account you already have.

ChatGPT Plus is £20/month. Claude Pro is £20/month. You probably already have one. Build My Bid Manager runs entirely inside that account — no API keys, no developer setup, no third-party platform, no separate login. Just a browser, your documents and the prompts.

the compounding advantage

the library gets stronger after every bid.

  • First tender builds the Company Brain, Evidence Vault and Case Study Library.
  • Second tender draws from the library — drafting is faster, evidence is stronger.
  • Third tender adds new case studies, closes evidence gaps, scores more consistently.
  • Post-bid learning loop extracts Grade A content after every submission — no exceptions.
  • After six months, your library is a competitive asset built from six tenders — not six consultants.

"we can't guarantee you'll win. we can guarantee your next tender will be built on verified evidence, scored from the evaluator's perspective, and structured to compete at the highest level."

Public sector procurement is competitive. The contract goes to the strongest submission on the day — not necessarily the best-performing supplier. What we give you is every possible advantage before the evaluator opens your response. The rest is yours to win.
