OK guys, have I got a good one for you! This company is making high performance electric outboard and inboard power trains for boats for sale to existing boat manufacturers. They are tiny (14 employees. OK, really tiny). AFAIK, they have very little in the way of competition. They are looking to go public soon, and filed their F-1 (they are a Canadian company) on July 9th. Which means it'll be a month or two before they do go public (if they do).
You can read their F-1 here:

You can read about their technology starting on page 21.
This is a development stage company. While they have revenues, all they are currently doing is selling custom boats with another company's outboard electric motor. By doing so in the last couple of years, they have found that the overall system isn't very efficient. They believe by creating their own powertrain they can increase overall efficiency by a lot (like 80% or so). They have signed non-binding LOIs with boat OEMs to buy their powertrains when they finish development.
This is akin to buying Tesla before Tesla finished developing their Roadster. Except that the market is smaller. But still plenty big enough to propel this IPO. No doubt high risk since these guys could easily fall flat on their faces.
Company web site is here, but the prospectus is much more interesting:
