Investments into legal tech companies are hitting record-setting figures. But the true extent of funding amounts fueling legal tech and e-discovery software companies will likely never be widely shared.

"We're only capturing the big repositories, we're only seeing 20 or 25% of all the fundraising happening," said Raymond Blijd, CEO of Legalcomplex, an analytics company that tracks investments in legal and other industries. "This is like the proverbial tip of the iceberg. The ones we do see, they spin it like a win."
