They made $40k of a $150k goal in under 2 days. PicoBrew made $661, of a $150k goal. FlowHives make $12 million of a $70k goal. It's been gobbled up by people who want to be home brewers.
Thing is, there are a LOT of people out there who don't have time, inclination, skills, or whatever to be a scratch brewer. Many (possibly most) don't *enjoy* the crafting process. I have a PicoBrew. I love having home brews that I can dial in a recipe and make a new batch of sgain dubh (my current favorite) that tastes like the last batch of sgain dubh. I also love playing with grain and hops ratios to see what new variation or flavor I can make.
I hate spending hours in the kitchen coddling a boil (and cleaning up a boilover) so much that I won't do it. I don't have that kind of time in my life; I need to be doing about 10 other things than brewing a batch of beer that I could run to the store and find an adequate (not necessarily great) substitution for. Brewing beer from scratch with pots and strainers and whole grains and sticky mess is not "fun." Drinking home brews is great fun.
I love having homebaked breads. I know how to make bread from scratch; I did it for years. But I love that my bread machine takes the raw ingredients and turns out a dough that I can then shape and bake. My bread machine gives me back time, so I can be busy and still make home baked breads with my ingredients.
I love good honey, but I also happen to love the hands-on craft of beekeeping. I can lose hours in the apiary working my bees. I don't mind the sweaty bee suit, the stings, fighting propolis, wondering how the hives are doing in the middle of January, I love watching the bees work in the hive and out. It's fun for me.
Most people just enjoy having good, raw honey. They want to be able to turn the tap and have honey flow in to a jar. They don't want to get stung, they don't have inclination to spend hours with their bees. They're Flow Hive people. (Let's set aside whether the Flow Hives deliver on this for the moment -- that's yet to be seen, IMO.) I completely understand that. More power to them. We should have more raw honey available cheaper. We should encourage people to be craft brewers. And bakers.
As far as a product goes, the MiniBrew looks pricey, but it also looks attractive sitting on the counter. For the price, the 1.3 gallon size puts me off -- my ideal batches are about 3 gallons (mead or beer). There is precedence that the technology to make a contained small batch works (PicoBrew). The real question is can these particular innovators be able to mass-produce a machine that has a $2k value? Are they business-savvy as well as brew-savvy? My experience with crowdfunding is that the higher the technical complexity, the greater the chance that you'll end up a disappointed investor.
