Create corporate blog on https://habr.com/.
Habr is a platform featuring large number of software developers. They may be interested in technically advanced platforms such as Manifold and Manifold Dating; there is a commonly known effect when services mentioned there unexpectedly get high load.
On articles in Russian, average in the feed to the right ("most reading") is 10K visits and two-hour-old articles usually hit 500-2K visits.
Promotion of a brand is allowed provided that it's still a technically-related article and takes place in a corporate blog. Corporate blogs are quite expensive, $3'630/month.
I think Manifold has quite a lot of things to tell about, including company radical transparency approach, custom AMM with limit orders, etc!

The goal is
to attract new ecosystem with almost-zero prior intersection to Manifold, with users of reasonable (up to Trustworthy-ish) "quality"
by writing engaging articles about how Manifold works and what it can be used for.
Payment for corporate blog creation.
I and [to be updated: looking for one of Manifold core team members]. I have no past projects like this.
Outcome: Manifold doesn't get much more users.
Reasons: other language (not especially likely), conceptual mismatch.
Outcome: users aren't engaged for long.
Reason: Manifold Markets aren't helpful enough for users.
Outcome: Manifold gets bad PR.
Reasons: poorly written articles, forgetting to check comments, (improbable) significant conceptual mismatch (if Manifold is mistaken for something like sports betting and betting is claimed to be bad).
No other funding.
