Few thoughts:
(1) Depending on your acquisition contracts, you may have scattered access to historic imaging. For a consumer, having an image of my house around e.g. the time of a break-in is valuable. (As a party trick, recent imagery will work in a way “wait a day” doesn’t.)
(2) You’ve heard this, but it bears repeating: four hours is an order of magnitude more valuable than 24 and an order less than one. You should be able to predict fast-return windows, given orbits and ground station coordinates, for a given AOI. Bonus: natural time pressure on the sale.
(3) Multispectral options unclear. May be worth discriminating by band.
(4) Exclusivity pricing. Where you sell the image to me, fully, and without retaining the right to re-sell it to anyone else.
There also appears to be a name collision with an Israeli ISP?
