We're an enterprise SaaS company in the legal space. We make it easy for companies to manage and understand their legal spend. We replace PDFs with an interactive dashboard and flag outlier expenses based on industry benchmarks. Simple to setup, we receive bills via email from a company or direct from law firms. That's it. See how much you're paying, to whom, for what. Manage matters, legal entities, cost codes, annotations.
Legacy vendors include Bottomline Technologies (NASDAQ: EPAY $1B+ market cap), LexisNexis, Thomson Reuters. Legacy vendors serve only the very large customers (>$100M/yr in legal spend).
Free from legacy software, we are able to build our eBilling platform at a fraction of the cost of legacy vendors.
A competitor - DataCert - was recently acquired by Woltzer Kluwer at a $290m valuation
