Send Us Your Best.
We'll Beat It — or Say So.

Six standing challenges, run on your own documents, against your own benchmarks. Every result is publishable — pass or fail, the outcome goes in writing.

The proof protocol

Real documents. Real scenarios. Not a screenshot and a prayer.

We took the workflows your team already runs - bids, RAMS, CEs, CVRs, FM tickets - and put structured AI behind each one. Same documents. Same standards. A fraction of the time.

BYW · Window 1Pre-engagement

Bring Your Worst™

"Can it handle the hard stuff?"

Live on the first call. Bring your messiest tender, most overdue RAMS, or the variation nobody's had time to write up. We process it in front of you.

Beat Your Best™

"Is it actually any good?"

After the call. Send us the tender your team is most proud of - the one that took a week. We return a full output set from the same source documents.

The sequence

Bring Your Worst on the first call. Beat Your Best as the follow-up. Either can be used independently - but together, they're undeniable.

The promise
We don't sell with slide decks, scripted demos or fake data. We sell with proof - live, on your own documents, against your own benchmarks.
Six challenges · two windows

Every claim, testable in public.

Window One challenges (pre-engagement) settle questions before a contract is signed. Window Two challenges (in-engagement) settle questions during delivery. Each carries its own protocol, criteria, and a permanent record of the outcome.

BYB · The Beat-Your-Best Challenge

Window 1 · Pre-engagement
BYBWindow 1 · Pre-engagement

Send us your best-ever produced deliverable. We attempt to match or beat it on quality and time, against the same brief.

You nominate the artefact your team is proudest of - the cleanest tender, the tightest RAMS pack, the sharpest CVR. You send the brief that produced it and the time it took. BuiltAI runs the same brief through the same pack and reports the resulting artefact, the elapsed time, and a side-by-side honest read of where each version is stronger.

We will

  • Use the brief that produced your best-ever output, exactly as it was given to your team
  • Produce our version inside a window measured from kick-off to first usable artefact, capped at 1 week
  • Publish both versions side-by-side in the proof record, with elapsed time and a written read of strengths and weaknesses
  • Concede in writing where your version is materially better, by line item, with reasons
  • Stand behind our version for a 14-day audit window like every other challenge

We won't

  • Cherry-pick which of your deliverables to compete against, you nominate it
  • Pre-process the brief, what your team got is what we get
  • Compete on output type your pack does not cover, we will say so before kick-off
  • Run multiple attempts, first artefact is the only artefact

Success criteria

You score the comparison. The proof record publishes elapsed time on both sides, plus your written quality verdict (ours stronger, yours stronger, equivalent) - and where your version is materially better, we concede in writing.

Typical: Mid-market contractors and FM operators with mature in-house teams

TFH · The 24-Hour Challenge

Window 1 · Pre-engagement
TFHWindow 1 · Pre-engagement

Pick a workflow. We deliver a real, usable output in 24 hours. Not a slide. Not a mock-up. The artefact.

You name a workflow BuiltAI claims to support - a tender response, a CE submission, an MMS report, a RAMS pack. We produce the actual deliverable using the actual pack, against your actual brief. You score it as you would any internal output.

We will

  • Produce the artefact end-to-end using the pack you nominate
  • Use only data you provide in the brief - no scraping, no enrichment
  • Submit the output in the format your team would receive it (PDF, .docx, .xlsx)
  • Include the audit log showing how every section was built
  • Stand behind the output for 14 days, answer any line-by-line question

We won't

  • Pre-process the brief or coach the input, what you send is what we use
  • Show you a "lite" version or a sample, only the live deliverable counts
  • Run more than one attempt, first output is the only output
  • Trade the result for an NDA or a sales call

Success criteria

You score the output against three criteria: technical accuracy (does it stand up to internal review?), format fit (would you accept it from your own team?), and time-to-usable (how much editing before submission?).

Typical: Tier-2 contractors, specialist subcontractors, FM operators

CSC · The Cold-Start Challenge

Window 1 · Pre-engagement
CSCWindow 1 · Pre-engagement

We deploy a pack into your business with zero prior data. Day one to first usable output, measured.

"AI tools" need months of data ingestion before they produce anything useful. The Cold-Start Challenge tests the opposite: pack arrives Monday morning, first deliverable lands by Friday. The interval and the artefact quality are the score.

We will

  • Deploy any pack from the suite into your environment in 5 working days
  • Produce one full deliverable inside that window using only your live data
  • Measure and publish the elapsed time from kick-off call to first usable output
  • Withdraw at the end of week 1 if you decide not to proceed, no clawback

We won't

  • Pre-load the pack with synthetic or "industry standard" data to make it look ready
  • Claim a deliverable as "usable" without your explicit sign-off against your benchmark
  • Hide the timing, the elapsed clock is recorded regardless of outcome

Success criteria

Pass: a deliverable signed off as usable by your nominated reviewer within 5 working days. Fail: any longer, or rejected on the standard benchmark. Both outcomes are recorded.

Typical: Operations directors evaluating multiple AI tools, PE-backed 100-day plans

ATC · The Audit Trail Challenge

Window 2 · In-engagement
ATCWindow 2 · In-engagement

Open any output BuiltAI has ever produced for you and ask us how every line was derived.

A continuous, in-engagement obligation. At any point, on any deliverable, you can ask BuiltAI to walk you through the derivation of any value, paragraph, or recommendation. We hold ourselves to a 4-hour response window for the trace.

We will

  • Produce the full chain of inputs, prompts, intermediate outputs, and review checkpoints for any line item, on demand
  • Respond within four working hours in normal cases, and by the next working day otherwise
  • Include any AI model decisions made during generation - what was kept, rejected, edited
  • Sign every audit response so it can be put in front of your auditor or PE house

We won't

  • Hide behind "the model just produced it", every output has a trace
  • Charge separately for audit responses, they are part of the engagement
  • Limit how many audits you can run, there is no fair-use cap

Success criteria

Pass: the audit trace satisfies your standard for an internal-or-external audit response - built to stand up in front of trust auditors, PE operating partners and due-diligence teams.

Typical: Continuous obligation, invoked routinely on every engagement

DGC · The Disagreement Challenge

Window 1 · Pre-engagement
DGCWindow 1 · Pre-engagement

Ask us where BuiltAI is the wrong answer for you. We will tell you, in writing, before you sign anything.

Most vendors have one mode: yes. The Disagreement Challenge gives you a structured way to make us prove we have a "no" mode. You describe your operation; we tell you where our pack would underperform a manual process, where the implementation cost outweighs the saving, and where another tool would be a better fit.

We will

  • Produce a written assessment naming at least three areas where BuiltAI is not the right answer for your operation
  • Recommend specific alternative approaches (manual, other vendor, no-action) where applicable
  • Sign the assessment so it stands up if you raise it with us in 6 months
  • Update the assessment if your operation changes materially during the engagement

We won't

  • Produce a generic "limitations" disclaimer dressed up as a disagreement
  • Refuse to name competitors where they are the better fit
  • Soft-pedal the assessment to keep the deal warm

Success criteria

Pass: an assessment specific enough that you would forward it to a peer with your name on it. Fail: a generic limitations document. If the honest answer costs us the engagement, that is the point.

Typical: FDs, Operations Directors, PE houses doing operational due diligence

INV · The Inversion Challenge

Window 1 · Pre-engagement
INVWindow 1 · Pre-engagement

Take any case-study output we publish. Replicate it without our toolset, in any timeframe, at any cost. Tell us what it took.

The Inversion Challenge is for businesses already running internal AI initiatives. We publish a case-study deliverable - a specific tender response, a specific commercial pack - and invite you to produce the equivalent yourself, with whatever tools and people you choose.

We will

  • Provide the full brief, source data, and benchmark that produced our published output
  • Publish your reported time and cost in the proof record alongside our reported time and cost
  • Withhold judgement on output quality, that comparison is for you and your team
  • Treat your reported figures as confidential to the degree you specify

We won't

  • Compete on output quality in this challenge, only the production economics count
  • Cherry-pick which case-study output to expose, the brief is published in full
  • Filter the proof record, every reported figure goes in, including ones that beat ours

Success criteria

There is no "pass" or "fail": both reported sets of figures are published and you decide whether the difference matters at your scale - including any where the challenger beats ours.

Typical: In-house AI/ML teams, large contractors with internal innovation budgets
The register

Every outcome, on the record.

The register publishes real challenge outcomes as they happen — pass, revised, or fail — each with the challenger's written consent and the initials of the approver who signed the result. No back-dating, no worked examples: every entry is dated after incorporation (8 June 2026) and stays on the record.

Register · 0 entries

No public runs recorded yet.

The protocol is live; the register fills only with real, signed outcomes — never worked examples. The first challenger who agrees to publication takes the first line. Be the first.

Issue your challenge ↓

Publication policy: entries appear only with the challenger's written consent; challengers are anonymised to sector, size and region unless they ask to be named; a revised or failed run is published with the same weight as a pass.

The division of labour

BuiltAI does the heavy lifting.
You Keep the Judgement.

Bringing your worst doesn't replace your team. The pack does the structured, document-heavy work. Your team keeps the commercial calls, the contractual positions, and the relationships that win the bid. The Proof Protocol is how you check, in writing, that the division of labour holds.

Send us the document your team doesn't want to send.
We'll send it back, rebuilt.

12 minutes on the call. 24 hours after. Either way, you get the artefact and the outcome in writing.
