Duolingo (DUOL): hiring and filings, side by side
Two independent records on the same company. What Duolingo tells a regulator, and what it is doing on its own careers page. Neither is a comment on the other, which is exactly why they are worth reading together.
Why this page is not somewhere else. Trading-signal vendors sell the filings and workforce-data vendors sell the hiring, but the two are rarely joined on the same company in the same window. The hiring side here is read from the employer's own applicant tracking system rather than scraped from a job board, every filing links back to the document on SEC EDGAR, and each score states the inputs it was built from so you can recompute it instead of trusting it.

Where the hiring sits: Software Engineering (14), Marketing and Communications (10), Product Design (5), Talent Acquisition (4), AI + Machine Learning Engineering (4).
Where the roles are: United States (48), United Kingdom (4), Japan (2).
How that number is moving
Over the 7 days to 2026-08-20: 9 roles opened, 12 closed, -3 net - more closed than opened.
Across 12 readings the average is +1.1 per window. The window rolls daily, so consecutive readings overlap; the direction is the signal, not any single figure.
A large company always has hundreds of open roles, so the count on its own says little. The direction does.

Reading the two together
Over the last 7 days this company's open-role count was shrinking (-3: 9 opened against 12 closed). In the same period, 4 notices of intent to sell were filed for a combined $862,630, by Natalie Glance and Robert Meese and 1 others (officer); an 8-K was filed on 2026-08-10 covering departure/appointment of directors or officers; AQR CAPITAL MANAGEMENT LLC reported a passive 5%+ position. These are published by different teams on different calendars, for different reasons. Neither explains the other, and this page does not claim it does.
Being straight about what this is
Not advice. This page reports what two public sources say. It does not tell you what to do with that, and the direction of one does not predict the other.
Some scores are built on incomplete inputs. Where a filing does not publish every term the formula uses, the record carries inputs_complete: false and the score is still shown. The gap is reported, not filled in with a guess.
A short observation window. We started recording opens and closes on this set in August 2026, so "what changed" is weeks deep, not years. It grows daily. The filings themselves reach back as far as the publisher provides.
Refreshed once a night. Not real time, and some publishers are slower by nature: congressional trades weekly, institutional holdings quarterly.
Names come from the filing. Where a person is named, that name is a required disclosure field in the public filing itself, and the link above goes to it.
