Today we are excited to announce the details of our seed funding. Momentus provides in-space transportation services for satellites between various orbits out to deep space. Our mission is to provide the most efficient in-space transportation services powered by deep space resource utilization, and the individuals and organizations outlined below will help us achieve our goal.We would like to especially thank Prime Movers Lab, who led the $8.3M round, with participation from Liquid 2 Ventures, One Way Ventures, Mountain Nazca, Y Combinator, and numerous others.
Momentus has not only developed groundbreaking and efficient water-powered, in-space rockets, but also validated the massive market demand for their services with hundreds of millions of dollars in LOIs.

Interesting company, looks like they are developing a water based in-space tug.https://momentus.space/2018/11/14/proudly-announcing-8-3m-in-seed-funding/
God their website is annoying. "Just tell me the facts, ma'am."Anyway, 700 seconds seems.. okay, I guess? I mean, it's an order of magnitude less than SEP is capable of, but I suppose they've traded-off for higher T/W, which is a legitimate concern if you're going to spend a lot of time climbing in and out of gravity wells. I would like to see some considerably more detailed numbers, though.
I couldn't find 700 sec just x3 more than chemical.
500-1250 KG WET MASS180 KG PAYLOAD TO LUNAR ORBIT FROM LEO250 KG PAYLOAD TO MARS ORBIT FROM GTOUP TO 6 KM/SEC ∆V2-3 KW SOLAR PANELSSPECIFIC IMPULSE UP TO 700 SEC
STARTING MASS 180 KG (ESPA)OR 300 KG (ESPA GRANDE)UP TO 6 KM/SEC ∆V500 W SOLAR PANELSSPECIFIC IMPULSE UP TO 700 SEC
...the latter option is kind of interesting as you could just launch water anytime a Dragon or Cygnus launch is volume-limited. Using ISS as a sort of ad hoc propellant depot.

Using ISS as a sort of ad hoc propellant depot.That's an interesting thought, relative to Orbit Fab and their water tanker testing to be done at ISS, and in the context of Jon Goff's 3 burn departure concept, which allows start at ISS orbit. By definition the propulsion stages need to be long lived for electric propulsion, though there is the deviation from the original 3 burn concept (refuel an existing upper stage for first burn).
What's stopping Rocket Lab from expanding the capabilities of the kick stage, and effectively do what this company is trying to do by marketing it? Curie has the flight heritage under its belt.
