At its traditional evening keynote at re:Invent, AWS tonight announced quite a bit of new hardware in its cloud, starting with a new version of its Nitro hypervisor, new instance types, and a new version of its custom Arm-based Graviton chips which was specifically designed for powering high-performance computing workloads. This new Graviton3E chip — a variant of the existing Graviton line — promises significant performance improvements, including 35% better performance for workloads that heavily depend on vector instructions.

These new chips will obviously power new AWS EC2 instance types, starting with the logically dubbed Hpc7G. This new instance type will come in a variety of sizes, with up to 64 vCPUs and 128 GiB of memory. It’ll take until early 2023 before these instances become available, though. For more network-intensive workloads, AWS is also launching a new Graviton 3E instance type (c7gn).

For Intel fans, there are also new Ice Lake-based Xeon-based machines, too.

All of these new instances will make use of AWS’s new Nitro 5 hardware hypervisor, which the company also announced today. Nitro v5 promises significantly improved latency, up to 40% better performance per watt, and 60% higher PPS. The AWS team made this possible by roughly doubling the number of transistors in the custom Nitro chips.

“Performance can be hard to achieve when you refuse to budge on things like security and cost,” Peter DeSantis, Senior Vice President of AWS Utility Computing, said in tonight’s keynote. And in many ways, that’s long been the story of AWS’s compute platform and its work on its custom processors.

On November 22, alternative financing startup Pipe announced that its three co-founders were stepping down from their executive roles and that a search for a new, “veteran” CEO had commenced.

In an exclusive interview, co-founder and former co-CEO Harry Hurst told TechCrunch that the trio were “0-1 builders, not at-scale operators.” He said the company’s revenue was growing year-over-year and that the company had five years of runway.

Finding the right successor could take a while, however. For starters, Pipe — which has raised more than $300 million from investors since it was founded in 2019 — has just one outside board member in Peter Ackerson, a general partner at Fin Capital who himself became a VC just three years ago. Hurst and fellow founders Josh Mangel and Zain Allarakhia are the only other directors on the board.

More, detractors seem bent on raising questions about the way the business has been run. Since that article was published, several sources who wished to remain anonymous — including one investor who says he passed on investing in the startup in its early days — have said that they have “heard” that Pipe made roughly $80 million in loans to one or several crypto mining companies. The outfit or outfits have since gone out of business and the $80 million is believed to have been completely written off, said these individuals.

Asked about the allegations, a company spokesperson told TechCrunch that Pipe did not issue $80 million worth of loans to crypto mining companies and that Pipe did not have to completely “write off” any related receivables. Instead, she confirmed that Pipe “has provided access to financing to crypto mining hosting companies” and said — when asked if Pipe has lost any amount of money on loans to crypto mining entities — that as a private company, Pipe does not share its company financials.

The startup declined to name its crypto mining-related customers, but notably, Pipe had a public partnership with Compass Mining, a now beleaguered crypto mining company that is reportedly facing its own fair share of struggles.

There are other grumblings. One source alleged that Hurst and the other two founders sold millions of dollars’ worth of their own shares in a secondary sale, a practice that became fairly common during the pandemic across numerous young companies. (The founder of Hopin, also founded in 2019, has reportedly cashed out shares worth at least $195 million.) When we asked Hurst last week just how much investors had let the co-founders take off the table already, he declined to answer.

One fintech investor also raised questions about the sophistication of Pipe’s technology. Asked whether there was any related issue with Pipe’s underlying loans, the company’s spokesperson said, “While we’ve seen some delinquencies on the platform like many fintechs in this current macro environment, we do not expect buy-side investors to experience losses that haven’t already been communicated to them or a part of the larger risk profile communicated by the company.”

Hurst has apparently been hearing about the conjecture around his company. In a Twitter thread last night, he ranted against “VCs and others hating on our company based on rumors. Pretty obvious there are bad actors with their own agendas spreading BS with no regard for the people it damages.” He also wrote: “As a leader, I won’t let this noise distract us or undermine the incredible hard work our team puts into achieving our mission to empower companies everywhere to grow on their terms.”

Meanwhile, the CEO search continues. Indeed, Pipe’s spokesperson reiterated today what the company said publicly last week, that “Josh [Mangel] is now interim CEO and Harry is still at the company in his new capacity as Vice Chairman. They both want to see Pipe reach its ultimate potential and are committed to finding a new CEO as reported and announced…”

Once Pipe’s new CEO is named, she added, that individual will assume Hurst’s seat on the board.

As for who is helping with the search, she said the answer is that “many of Pipe’s stakeholders are part of the CEO search process, including senior management and investors.”

Besides Fin Capital, other VCs to lead investments in Pipe on the part of their investment firms include Marlon Nichols, a managing director at MaC Venture Capital, and Ashton Newhall, a longtime investor with Greenspring Associates and now a partner with StepStone Group, which acquired Greenspring in September of last year.

None responded to requests for comment.

Another investor in Pipe, Matthew Cowan of Next47 Capital, told TechCrunch that he was “not allowed to comment.”

Other backers in the company include Morgan Stanley’s Counterpoint Global, CreditEase FinTech Investment Fund, 3L, Japan’s SBI Investment, Marc Benioff, Alexis Ohanian’s Seven Seven Six, Republic and Craft Ventures, which led the company’s $6 million seed funding in February 2020.

Meanwhile, aForm-D signed by Pipe Senior Counsel Peter Chiaro with the U.S. Securities and Exchange Commission in late September reveals that the company recently secured $7.12 million in debt financing, which could be construed as a positive alternative to the kind of highly structured inside round that many startups are closing currently.

Pipe co-founder and chief business officer Michal Cieplinski, whose name was absent from the company’s announcement last week, was listed as Pipe’s “executive officer” in the filing, which declined to disclose its revenue range.
