One firm, one Brain, one memory: why we refuse to pool

The most consequential sentence on our site is five words long: one firm, one Brain, one memory. It is also, commercially speaking, the most expensive sentence, because the opposite choice, pooling customers into one system that learns from all of them, is how software companies usually scale. This article is about why we made the expensive choice, and why we think any firm whose work is judgement should demand it from whoever they buy.

What pooling actually trades away

When a supplier learns across its customers, every customer's edge becomes the pool's property. Your way of pricing, your pattern of passing on deals, the clause your office invented after a bad year: it all flows into a model that serves your competitors the moment they subscribe. The pitch calls this network effects. From the firm's side of the table it has an older name: giving away the shop, gradually, in a subscription.

For volume businesses the trade can be rational; a webshop gains more from the pool than it loses. For a professional firm the mathematics reverse. A notary's office, a fund, an M&A boutique is its accumulated judgement. Pool that, and what exactly is the firm still selling?

What separation makes possible

Separation is not only defence. Things become possible inside a dedicated memory that a pooled system cannot offer at any price.

The Brain can hold the whole of the firm: every client's history, every deal's outcome, every correction a partner ever made, without any question of who else might see it. Depth of memory is precisely what a pooled system must limit, and depth is where the value is.

The rules can be the firm's actual rules, not a configuration of someone's average. What may leave the building, who approves what, which clients are handled how: encoded exactly, because there is no other tenant to compromise with.

And the exit stays real. A firm whose memory lives in its own dedicated system can take everything and go. A firm woven into a pool can export records, but the learning, the part it paid for with years of its own work, stays behind by construction.

The honest cost

Separation costs us scale economics, and it costs the firm the comfort of the word standard. Every Brain is built at its firm's table, which takes weeks of that firm's attention. We think the trade is obviously right for professions where judgement is the product, and we notice that the firms who have thought hardest about it, and their regulators, and increasingly their clients' diligence teams, keep arriving at the same conclusion.

The guarantees that make separation enforceable rather than promised, the scoping, the log, the exit in writing, are set out on Trust and data. The five-word sentence is the first one on that page, where it belongs.
