Federal awards are summed by year (61 awards); hover a bar for the split. Form D reports securities sold, which can differ from an announced round; filings are numbered in the order they were made.

1 record has no date or no amount, so it isn’t placed on the timeline.

Cumulative measures favor older companies. Rankings describe position today, not outcome. Below the median, ranks show as a band rather than a number.

Founders and team

No founders are linked to this company yet.

Founders appear once a person is matched to the company through its own patents, grants or filings. We never infer people from social profiles.

What it has protected

No granted patents are on record.

USPTO usually publishes applications 18 months after filing, so recent applications may not be visible yet. Patents assigned under a different entity name won’t match.
