The companies you care about are public, whether they file or not.

Public companies file 10-Ks. Private companies don't. But the surface area of any company — hiring patterns, product launches, news pickup, social sentiment, website changes — is public to anyone willing to look.

Sonarna does that looking, in real time. Build a watchlist of public and private companies, and we surface what's actually happening across them: news polarity shifting, careers pages adding senior roles, the product changing under the hood, conversation on Reddit moving in one direction or another.

The original audience was operators tracking their own brand and a small set of competitors. Investors picked it up next, because the pre-IPO information gap is most acute when you most need to act on it. Both groups need the same thing: a daily, complete picture of what changed.

What we do, specifically

• News, with sentiment

  Press mentions for any tracked company, scored for polarity (positive, negative, neutral), grouped by topic (funding, partnership, legal, executive, other). High-signal events emit change records you can subscribe to.

• Reddit and social

  Pick the subreddits relevant to your company, and we'll listen for mentions of it (and its product names, tickers, and aliases). Volume and sentiment land on the same dashboard as the news data.

• Hiring activity

  Job posting feeds for tracked companies, with new-role and new-department flags. A surge of senior infra hiring is rarely random.

• Website and product changes

  We crawl the company's site, fingerprint product pages, and watch for substantive changes — copy rewrites, new product surfaces, tech-stack migrations.

• Baseline OSINT

  Historical record from public registries, EDGAR filings, WHOIS, and the Wayback Machine. The ground truth your other surfaces drift around.

What we don't do

No paid data feeds, no scraping anything that isn't already public, no reselling individual user data. Every signal Sonarna surfaces could be assembled by hand by an analyst — we just do it for the entire watchlist every five minutes instead of for one company every quarter.
