&Truth reportedly raises $70M to automate formal software verification

The startup is betting that automation can make mathematical bug-proofing cheap enough for everyday software teams Software developers have long dreamed of proving, with actual math, that their code has no bugs. &Truth has reportedly raised $70 million to turn that dream into something companies can buy. The startup wants to automate formal verification, according to Wired. The technique is powerful but rarely used. Why proving code is so hard Formal verification works differently from ordinary testing. Testing checks how a program behaves in situations engineers think to try. Formal verification aims to show, mathematically, that the program behaves correctly in every situation. The work has historically been slow and painful. Engineers must first write precise statements describing what their software is supposed to do. They then translate the code into formulas that a machine can check against those statements. Each step demands specialized skill and lots of time. Most companies decide the bill isn’t worth paying. They run sophisticated test suites to catch as many flaws as possible and accept the leftover risk. &Truth is reportedly targeting that gap with its $70 millio...
