The problem

Tender review shouldn’t cost you the weekend.

Endless bids, last-minute submissions, documents no one can find — the review that decides the award is the one done fastest, under the most pressure.

01 · Endless bids

Hundreds of pages, five bidders, one deadline.

Every return arrives in its own format — a priced schedule here, a qualifications letter there, a 400-page scanned ITT pack in a ZIP. Reading it all, once, would take days you don’t have.

02 · Last-minute submissions

The final return lands an hour before close.

Revisions arrive after the tender is meant to be levelled. Re-reading everything to fold one in isn’t realistic — so the late bid gets the lightest look, exactly when it matters most.

Which version was priced? Nobody’s sure.

Addenda, superseded drawings, a clause qualified three emails deep. Without a trail, an obligation slips through — and the gap only surfaces once it’s a variation on site.

The solution

One read. The comparison levelled, the risks flagged.

Sophia reads the whole pack and returns the grid that decides the award — no reformatting, no copy-paste into a template first.

Award recommendations

A defensible recommendation with the levelled numbers and the reasoning behind them, ready for the board.

Audit trails

Every decision and its source line preserved — so the paper trail holds up long after the award.

Customise every export

Tables, deltas, stacked bars and heatmaps — pick the view, brand the pack, export to your own format.

Privacy first

Your tenders stay yours. Full stop.

Every document lives in a private, UK-hosted, per-team database — encrypted, stored securely, and never used to train a model.

Encrypted end to end

Documents are encrypted in transit and at rest, isolated to your team’s database.

UK-hosted & sovereign

All data stays on UK infrastructure — built in London, Company No. 17250136.

Never trained on

We do not train models on your data. Your bids are yours alone — no exceptions.

On-site deployment

Need it inside your own environment? We offer on-premise options — get in contact.

FAQ

The questions we get asked first.

Can other people see my data?

No. Every tender lives in your team’s own private workspace — access is scoped to the teammates you invite and enforced on every table in the database, with documents encrypted in transit and at rest. Nothing you upload is ever visible to another team, and we never train models on your data.

Doesn’t AI hallucinate?

Left unchecked, it can — which is why Sophia isn’t a chatbot skim-reading your pack. Every value she extracts must cite the file, section and page it came from, and evidence-checking agents make separate verification passes: resolving each citation back to the source wording, hunting for caveats and qualifications, and re-inspecting the original documents. Anything that can’t be traced is flagged for review rather than asserted — and the evidence sits one click away, so you can always check it yourself.

Can I export my tender?

Yes. The analysis is yours to take with you — generate award recommendations, audit trails and board packs from the export studio, and export any comparison table or visual you’ve built. No lock-in.

Can we host on-premise?

Yes. nanosophia is UK-hosted by default, and for teams that need everything inside their own environment we offer on-premise deployment — get in contact and we’ll walk you through it.
