But then what value are you adding over Craigslist? You are basically a list of offices for rent, and owners put their space on your website, and maybe you crawl other sites to seed your offerings, too?

In most areas there are sites that are set up by real estate brokers. Their agents or licencees or franchisers or whatever input all properties in their central system and they all end up on that brokers website, and submitted to big sites as well. Is your schtick to squeeze out this middle man? To offer a platform to people who don't use agents? If so, how are you making money? Do people pay to list their properties, or do people finding properties pay you?

Look, not to be shitty about it, but you said e.g. this:

"We believe that Spacious can help liquidity in the market by making landlords and space operators confident that if they react to shorter contract lengths, they won't have to worry about long periods of vacancy as a potential tenant would be able to find them easily."

I see no other way to interpret this is 'we list your properties on our website so don't worry about losing 3-4-5 months of rent on a short term contract because we can find another one like that very fast'. Actually I didn't understand it like that at all when I had only read the OP, but the more you explain, the more I get the feeling this is it. What makes your site find tenants faster than other sites?
