Why this exists

The thing about a 10-K is that it tells you about a company three months ago.

Sonarna closes the gap between what a company is doing now and what its next filing will show.

Smart people make expensive decisions on stale information. A buy-side analyst builds a thesis from a 10-K that closed its window 90 days ago. A VC runs diligence on a company whose only filing is a pitch deck.

The gap between what a company is doing and what its next document will show is large, and it is closeable today. Not with insider information, never with insider information, but with what companies emit constantly: press, hiring posts, pricing pages, reviews, social. None of it is hidden. All of it is hard to assemble.

The wedge

One private AI company we track had four times the news coverage of a $2 trillion public peer. A 10-K would have shown us none of it. The public/private split stops being useful the moment you need to decide what to do this week.

What we do

Sonarna tracks any company you name, public or private, across news and sentiment, hiring, funding, leadership moves and website changes. Every stream lands in one schema, so any two companies compare on the same grid.

What we do not do. We do not predict prices. We do not generate trading signals. We do not handle insider information of any kind. Sonarna is a research tool, not a market terminal.

Who this is for

VC associates triangulating companies no database covers. Corporate strategy teams whose competitor map is six tabs of alerts. Buy-side analysts who open the week asking what changed on twenty names. If you want a tool that tells you to buy, sell or hold, this is not it.

In short

What it is

Real-time company intelligence. News, sentiment, change events and market data on every company you watch, public or private.

Who it's for

VC associates, corporate strategy, buy-side analysts, comms. Anyone whose decisions are bottlenecked by stale documents.
