Pre-submission bid intelligence
It doesn't write bids.
It deliberates them.
Eight specialists. One bid team that never leaves the room.
Institutional memory that learns from every edit, every outcome, every time.
Upload one bid. We'll show you what your team missed.
In plain English
BidEngine helps bid teams stop submitting weak answers. It reads the tender, finds the scoring risks, locks the win strategy, drafts from verified evidence, checks the response before submission and learns from every outcome.

Before deadline
every risk flagged in time
A live tender pack, processed end-to-end. Two days of evaluator-thinking compressed into a coffee break — with every weak answer and unverified claim flagged before submission.
Eight specialists. One bid team.
Each specialist feeds the next. Platform proposes. Your team owns the strategy. Platform executes against it.
BidVault
Holds the proofAtomises every uploaded doc into 80–150 structured records across 16 categories — original PDF one click away.
BidWrite drafts from atomised data. The buyer verifies against the source. Speed for the model. Proof for the buyer.
BidIntel
Reads the buyer
Two minutes replaces two days of desk research.
9-section intelligence pack — buyer, stakeholders, pain points, competitors, win themes — every claim cited.
BidGate
Calls the bid
GO / CONDITIONAL / NO-GO — scored against the buyer's actual criteria.
Reads BidIntel + the buyer's evaluation methodology. Win probability scored. Deal-breakers flagged. BidLearn closes the loop.
BidWrite
Drafts the answers
If you can't prove it, the platform won't write it.
Per-question drafting locked to verified BidVault evidence and the locked strategy version. Citations verified, not invented.
BidScore
Scores as you draft
Real-time scoring on each answer as you draft.
Question-by-question scoring the moment text lands. Weak claims, missing sub-questions and word-limit drift surfaced inline — long before BidCheck's final contextual audit.
BidRefine
Learns from the polish
Every human edit makes the next bid smarter.
Compares draft to polished final. Preserves tone, themes and avoid-list. Extracts net-new evidence back into BidVault.
BidCheck
Audits the work
A real evaluation panel's view — before submission.
Two-lens scoring. Compliance binary (did we answer every sub-question). Priority alignment weighted (did we hit what the buyer cares about).
BidLearn
Carries the lessonStop losing the same bid for the same reason — twice.
Tracks outcomes by buyer. Surfaces recurring weak categories. Feeds the next BidGate verdict — so win rate compounds, not flatlines.
What BidEngine is not
Don't put us in the writer bracket.
Not an autopilot writer.
Writers help you draft. We stop you submitting bad work — pre-submission scoring, evidence-locked drafting, every claim verified.
Not a proposal plugin.
Plugins glue onto Word. We sit between tender intelligence and submission — the whole pre-submission chain in one auditable spine.
Not a ChatGPT wrapper.
Wrappers reason from the public web. We reason from your verified evidence — and we can't write a claim you can't prove.
BidVault doesn't store bids.
It diagnoses them.
Most bid tools give you a library — somewhere to keep what you've written. BidVault structures your evidence across 16 categories and tells you, bluntly, what's missing. The gaps are why you're losing. No one else is telling you that.
Thin carbon data?
That's why the last DfT bid scored 6/10.
No social value evidence?
That's why framework renewals keep slipping.
No TUPE case studies?
That's why FM tenders keep going to the incumbent.
None of these get fixed by better writing.
They get fixed by better evidence. BidEngine is the first bid tool that will actually make you do that work — and measure whether it worked.
How it works
Four steps.
One human approval at the heart.
From tender pack to scored, evidence-backed submission. Platform proposes. Your team owns the strategy. Platform executes against it.
Read the tender
BidIntel profiles the buyer in two minutes — stakeholders, pain points, competitors, win themes, every claim cited. BidGate scores readiness against the buyer's actual evaluation criteria. Deal-breakers flagged before you commit weeks to a tender you were never going to win.
Lock the strategy
Strategy Lock auto-populates the win position, ranked priorities and must-prove claims. The bid team reviews, refines, signs. Versioned audit row. Every downstream answer carries the strategy version that produced it — to user, model and regulator.
Draft from evidence
BidWrite drafts per-question, locked to verified BidVault evidence and the locked strategy version. The model literally cannot output a claim you can't prove. BidCheck audits every answer end-to-end — compliance binary, priority alignment weighted.
Refine and learn
BidRefine extracts net-new evidence from your polish and feeds it back into BidVault. BidLearn tags the outcome by buyer and feeds the next BidGate verdict. Win or lose, the engine gets sharper. Your tenth bid is measurably stronger than your first.
Strategy Lock.
The bid team's signature on the strategy.
Most bid tools run end-to-end automation. BidEngine inserts a human approval step between intelligence and drafting — every win position, ranked priority, must-prove claim, tone and avoid-list approved by the bid team. Signed, dated, version-stamped, and propagated downstream.
The “guardian agent” pattern Gartner is calling — built natively into the bid workflow, not bolted on after the fact.
Platform proposes
Intel + Gate
Buyer profile, win position, deal-breakers — auto-drafted from the tender pack.
Bid team owns
Strategy Lock
Review, refine, lock. Versioned audit row. Live evidence readiness checked.
Platform executes
Write + Refine + Check
Drafts, scores and audits — all against the approved strategy. Every output stamped with the version.
Signature feature
Live evidence readiness
Every must-prove claim runs a live BidVault search the moment you type it. Three states — see the evidence gap before you lock, not three days from submission.
Audit trail
Versioned audit trail
Every lock event creates a permanent, immutable row. Re-locking creates v2.0 — prior versions preserved, status-flagged superseded. Full chain visible: who locked what, when, with which position.
BidEngine is built around a versioned human-approved strategy layer. Every drafted answer carries the strategy version that produced it.
