Buf, a Toronto-based startup focused on improving protocol buffers, tells Axios that it has raised over $93 million in funding since being founded last year.

Why it matters: The company is working to change how machines and computers communicate with one another, automating away a lot of API implementation work. Or, put more simply, it wants to help give engineers some of their time back.

  • The funding includes a $68 million Series B round closed last month, co-led by Lux Capital and Tiger Global.
  • Other backers include Greenoaks, Lightspeed, Addition and Haystack.
  • Proceeds will mostly be used to hire. Buf currently has around 20 employees, but says "there is enough work" for up to 150 people, who'd be split between Canada and the United States.

The Swedish electric boat startup Candela has raised $27 million from investors led by EQT Ventures, making it the latest of several firms in that space to attract fresh investment.

How it works: The company is looking to commercialize multiple types of boats that use hydrofoil technology, or "computer-guided underwater wings." They say this requires much less energy to propel the vessels.

Federal judge blocks Biden's vaccine mandate for federal workers

A federal judge in Texas blocked the Biden administration from enforcing its coronavirus vaccine mandate for federal workers on Friday, citing the outcome of last week's Supreme Court ruling that nullified the administration's vaccine-or-test requirement for large employers.

Why it matters: It's a blow to President Biden's efforts to increase the U.S.' vaccination rates, though much of the federal workforce has already been vaccinated against the virus.
