BF is a small company, and likely to stay that way. It's just not a business model that leads to growth. Handbuilt frames in low quantities sold mostly direct doesn't exactly scale up in any significant way.
I suppose if they invested a few million into robotic production and a large factory, it might be workable, but unlikely to turn a profit for quite some time, and where would that investment come from if they're already trying to raise $100K in stock offerings? And when you scale up production, all kinds of issues can occur in the supply chain, distribution network, and warranties/returns/recalls.
I like their product and wish them the best, but it's hard to compete with Bromptons and Dahons with what is essentially a handcrafted niche product produced in small numbers. I agree with Abu in one regard - the folding market seems to be exploding in Asia, and the more those products become available in the US, the less market share BF sees.
