If "startup" is defined as a for-profit company, then I'm not aware of any. There are non-profit organizations that work on alternative voting (Approval voting [0] and STAR voting [1] and Instant Run-off/Rank Choice), non-partisan primaries, non-partisan districting, proportional representation (no districts), electoral college reform.<p>[0] <a href="https://electionscience.org/" rel="nofollow">https://electionscience.org/</a><p>[1] <a href="https://www.starvoting.us/" rel="nofollow">https://www.starvoting.us/</a>
Probably some nontraditional nonprofits but they're likely to be classified as "Terrorist organizations" by those who disagree with their goals... Defnitely a higher risk investment.
