This company's burn rate is over $400,000 now according to http://mattermark.com/how-we-spend-money-at-mattermark/.

It's abnormally risky to raise only enough money for 17 months of runway. I wish Mattermark the best, but this level of burn is not the most confidence inspiring.

Cutting burn rate is notoriously hard to do. Startups are built on dreams, and every single one of them has a longer list of things it wants to do than the capability to do them. Accepting that the status quo has changed means founders have to cut expectations of themselves and what they hoped to achieve in 6/12/18 months. Instead of cutting burn, many will start the hamster wheel of trying to raise money, even at unfavorable terms, and realize the reality only too late.

Short answer: burn rates will continue to be high until too late into the down cycle. So current levels matter, a lot.
