Where the numbers come from, how they are checked, what the labels mean, and what PrePost does not do.
Every figure on PrePost carries a date and a source. A figure that cannot be sourced is left empty: "no independent evidence exists" is a finding, not a gap to fill. We never publish a number taken from a seller, a pitch deck or a requester's own documents.
Sources are used in this order, and a weaker one never overrides a stronger one:
Non-US figures are converted at the Federal Reserve's published rate for the transaction date.
New profiles and the Technology tab are researched once, then checked by a second, independent pass that has not seen the first one's reasoning and re-reads the source documents: each patent page, each paper, each acquisition announcement. The second pass has removed wrong founders, misattributed patents and out-of-date court rulings before they reached a page. Company performance claims appear only labelled as the company's claims.
Every valuation on a company page carries one of three labels, so a completed deal is never confused with a figure that is still moving.
A secondary-market price is market data, not a deal, so it carries no label. It appears beside the closed figure with its own date. A price read before the newest closed round is left out until it has been read again.
Each current estimate carries a confidence label that describes the evidence behind it. The estimate is shown on the compare page and in the offer check, and the trailing return on a company page is measured to it. Where the estimate is not the closed round, the return says what it is measured to.
Whatever the confidence, the company page leads with the last closed round, the figure someone actually paid.
A score from 0 to 100 that lets you compare companies on three measures:
The exact weights are not published. The Index is not a rating of the investment: a company can score high and still be a poor deal at the price you are offered, which is what Check my offer is for.
No advice, no buy or avoid ratings, no probabilities of success, no recommended amounts. PrePost does not verify the person or firm making you an offer, and does not see your offer documents. It gives you sourced figures to set next to what you were told; the decision is yours.
PrePost does not sell or broker shares, and today it has no commercial relationship with any company, fund or seller it covers. If that changes, this page will say so, any paid relationship will be labelled wherever it appears, and it will never affect a published figure or the Index.
Nobody pays to be listed. Companies, benchmarks and investment vehicles appear here because they meet the criteria on this page, and they are ordered alphabetically or by a published figure — never by payment, and never by how attractive we think they are.
PrePost's founder invests in private companies, and may hold positions in vehicles listed on this site. Those holdings never affect what is listed, the order it appears in, or any figure. This is disclosed here rather than repeated on every page.
