Nothing to discourage the efforts here but close to 10 companies were closed which tried to enter in FPGA market in last 10 years alone. Here is the list : TierLogic , CSwitch, Ambric, MathStar, Agate Logic, Nusym, AboundLogic (M2000)

Only one successful acquisiton. Lattice acquired --> Silicon Blue

In the past, ST Micro tried 2 times to enter in FPGA Market, once even with the "open Source " concept - GOSPL. Intel for once for sure. Other several companies failed too.

Xilinx and Altera hold close to 90% market share in FPGA market. 90% of other efforts to enter this market have failed earlier. Mostly because, companies underestimated Software importance.
