Republic operates exclusively under Title III of the JOBS Act, which was enacted in May of this year and is intended for early-stage companies.
On deal terms, generally speaking it would be impractical for a startup to fundraise via equity crowdfunding if the hundreds or thousands of investors, each putting in as little as $10, were to have voting and information rights. The non-transferability component is actually a legal restriction put in place by the SEC, not a term that any companies raising on Republic have put in place.
Each deal page has a discussion section, if you have questions for the founding team of each company, please do ask :)
