Right now there are several companies working on reusable launchers. SpaceX, of course, who already has a proven expendable orbital launcher. But also Blue Origin, Armadillo, XCOR, and Virgin Galactic. None of those companies have an orbital launch vehicle but each is working on building the foundations for reusability in the form of pioneering various control mechanisms (vertical landing being one) as well as engineering various component parts (from engines up to propellant tanks and so forth). Some of them are looking more at the sub-orbital space tourism market to provide early returns and some of them are certainly more dedicated and more well funded than others. Overall it'll be exciting to see what comes of it all.
