A French startup has raised a hefty seed funding to “rearchitect compute infrastructure” for builders wanting to construct and practice AI functions extra effectively.
FlexAI, as the corporate known as, has been working in stealth since October 2023, however the Paris-based firm is formally launching Wednesday with €28.5 million ($30 million) in funding, whereas teasing its first product: an on-demand cloud service for AI coaching.
This can be a chunky little bit of change for a seed spherical, which usually means substantial founder pedigree — and that’s the case right here. FlexAI co-founder and CEO Brijesh Tripathi was beforehand a senior design engineer at GPU big and now AI darling Nvidia, earlier than touchdown in numerous senior engineering and architecting roles at Apple; Tesla (working instantly beneath Elon Musk); Zoox (earlier than Amazon acquired the autonomous driving startup); and, most not too long ago, Tripathi was VP of Intel’s AI and tremendous compute platform offshoot, AXG.
FlexAI co-founder and CTO Dali Kilani has a formidable CV, too, serving in numerous technical roles at firms together with Nvidia and Zynga, whereas most not too long ago filling the CTO position at French startup Lifen, which develops digital infrastructure for the healthcare business.
The seed spherical was led by Alpha Intelligence Capital (AIC), Elaia Companions and Heartcore Capital, with participation from Frst Capital, Motier Ventures, Partech and InstaDeep CEO Karim Beguir.

The compute conundrum
To understand what Tripathi and Kilani try with FlexAI, it’s first price understanding what builders and AI practitioners are up in opposition to when it comes to accessing “compute”; this refers back to the processing energy, infrastructure and assets wanted to hold out computational duties akin to processing information, working algorithms, and executing machine studying fashions.
“Utilizing any infrastructure within the AI area is complicated; it’s not for the faint-of-heart, and it’s not for the inexperienced,” Tripathi advised TechCrunch. “It requires you to know an excessive amount of about easy methods to construct infrastructure earlier than you need to use it.”
In contrast, the general public cloud ecosystem that has developed these previous couple of a long time serves as a high-quality instance of how an business has emerged from builders’ must construct functions with out worrying an excessive amount of in regards to the again finish.
“In case you are a small developer and need to write an software, you don’t must know the place it’s being run, or what the again finish is — you simply must spin up an EC2 (Amazon Elastic Compute cloud) occasion and also you’re performed,” Tripathi stated. “You possibly can’t try this with AI compute at this time.”
Within the AI sphere, builders should work out what number of GPUs (graphics processing models) they should interconnect over what kind of community, managed by way of a software program ecosystem that they’re totally liable for establishing. If a GPU or community fails, or if something in that chain goes awry, the onus is on the developer to type it.
“We need to carry AI compute infrastructure to the identical stage of simplicity that the overall goal cloud has gotten to — after 20 years, sure, however there is no such thing as a cause why AI compute can’t see the identical advantages,” Tripathi stated. “We need to get to some extent the place working AI workloads doesn’t require you to develop into information centre specialists.”
With the present iteration of its product going by way of its paces with a handful of beta prospects, FlexAI will launch its first industrial product later this 12 months. It’s mainly a cloud service that connects builders to “digital heterogeneous compute,” which means that they will run their workloads and deploy AI fashions throughout a number of architectures, paying on a utilization foundation reasonably than renting GPUs on a dollars-per-hour foundation.
GPUs are very important cogs in AI improvement, serving to coach and run massive language fashions (LLMs), for instance. Nvidia is likely one of the preeminent gamers within the GPU area, and one of many foremost beneficiaries of the AI revolution sparked by OpenAI and ChatGPT. Within the 12 months since OpenAI launched an API for ChatGPT in March 2023, permitting builders to bake ChatGPT performance into their very own apps, Nvidia’s shares ballooned from round $500 billion to greater than $2 trillion.
LLMs are actually pouring out of the expertise business, with demand for GPUs skyrocketing in tandem. However GPUs are costly to run, and renting them for smaller jobs or ad-hoc use-cases doesn’t all the time make sense and might be prohibitively costly; because of this AWS has been dabbling with time-limited leases for smaller AI tasks. However renting continues to be renting, which is why FlexAI needs to summary away the underlying complexities and let prospects entry AI compute on an as-needed foundation.
“Multicloud for AI”
FlexAI’s place to begin is that almost all builders don’t actually take care of probably the most half whose GPUs or chips they use, whether or not it’s Nvidia, AMD, Intel, Graphcore or Cerebras. Their foremost concern is having the ability to develop their AI and construct functions inside their budgetary constraints.
That is the place FlexAI’s idea of “common AI compute” is available in, the place FlexAI takes the person’s necessities and allocates it to no matter structure is sensible for that individual job, caring for the all the mandatory conversions throughout the totally different platforms, whether or not that’s Intel’s Gaudi infrastructure, AMD’s Rocm or Nvidia’s CUDA.
“What this implies is that the developer is simply targeted on constructing, coaching and utilizing fashions,” Tripathi stated. “We care for the whole lot beneath. The failures, restoration, reliability, are all managed by us, and also you pay for what you utilize.”
In some ways, FlexAI is getting down to fast-track for AI what has already been occurring within the cloud, which implies greater than replicating the pay-per-usage mannequin: It means the power to go “multicloud” by leaning on the totally different advantages of various GPU and chip infrastructures.
FlexAI will channel a buyer’s particular workload relying on what their priorities are. If an organization has restricted finances for coaching and fine-tuning their AI fashions, they will set that throughout the FlexAI platform to get the utmost quantity of compute bang for his or her buck. This would possibly imply going by way of Intel for cheaper (however slower) compute, but when a developer has a small run that requires the quickest doable output, then it may be channeled by way of Nvidia as an alternative.
Below the hood, FlexAI is mainly an “aggregator of demand,” renting the {hardware} itself by way of conventional means and, utilizing its “sturdy connections” with the oldsters at Intel and AMD, secures preferential costs that it spreads throughout its personal buyer base. This doesn’t essentially imply side-stepping the kingpin Nvidia, however it presumably does imply that to a big extent — with Intel and AMD preventing for GPU scraps left in Nvidia’s wake — there’s a big incentive for them to play ball with aggregators akin to FlexAI.
“If I could make it work for purchasers and produce tens to a whole bunch of shoppers onto their infrastructure, they [Intel and AMD] will probably be very joyful,” Tripathi stated.
This sits in distinction to related GPU cloud gamers within the area such because the well-funded CoreWeave and Lambda Labs, that are targeted squarely on Nvidia {hardware}.
“I need to get AI compute to the purpose the place the present basic goal cloud computing is,” Tripathi famous. “You possibly can’t do multicloud on AI. You need to choose particular {hardware}, variety of GPUs, infrastructure, connectivity, after which preserve it your self. At this time, that’s that’s the one method to really get AI compute.”
When requested who the precise launch companions are, Tripathi stated that he was unable to call all of them as a result of an absence of “formal commitments” from a few of them.
“Intel is a powerful companion, they’re positively offering infrastructure, and AMD is a companion that’s offering infrastructure,” he stated. “However there’s a second layer of partnerships which are occurring with Nvidia and a few different silicon firms that we’re not but able to share, however they’re all within the combine and MOUs [memorandums of understanding] are being signed proper now.”
The Elon impact
Tripathi is greater than outfitted to cope with the challenges forward, having labored in among the world’s largest tech firms.
“I do know sufficient about GPUs; I used to construct GPUs,” Tripathi stated of his seven-year stint at Nvidia, ending in 2007 when he jumped ship for Apple because it was launching the primary iPhone. “At Apple, I grew to become targeted on fixing actual buyer issues. I used to be there when Apple began constructing their first SoCs [system on chips] for telephones.”
Tripathi additionally spent two years at Tesla from 2016 to 2018 as {hardware} engineering lead, the place he ended up working instantly beneath Elon Musk for his final six months after two folks above him abruptly left the corporate.
“At Tesla, the factor that I realized and I’m taking into my startup is that there are not any constraints apart from science and physics,” he stated. “How issues are performed at this time will not be the way it needs to be or must be performed. You must go after what the appropriate factor to do is from first rules, and to do this, take away each black field.”
Tripathi was concerned in Tesla’s transition to creating its personal chips, a transfer that has since been emulated by GM and Hyundai, amongst different automakers.
“One of many first issues I did at Tesla was to determine what number of microcontrollers there are in a automotive, and to do this, we actually needed to type by way of a bunch of these massive black containers with steel shielding and casing round it, to seek out these actually tiny small microcontrollers in there,” Tripathi stated. “And we ended up placing that on a desk, laid it out and stated, ‘Elon, there are 50 microcontrollers in a automotive. And we pay typically 1,000 occasions margins on them as a result of they’re shielded and guarded in a giant steel casing.’ And he’s like, ‘let’s go make our personal.’ And we did that.”
GPUs as collateral
Wanting additional into the longer term, FlexAI has aspirations to construct out its personal infrastructure, too, together with information facilities. This, Tripathi stated, will probably be funded by debt financing, constructing on a latest development that has seen rivals within the area together with CoreWeave and Lambda Labs use Nvidia chips as collateral to safe loans — reasonably than giving extra fairness away.
“Bankers now know easy methods to use GPUs as collaterals,” Tripathi stated. “Why give away fairness? Till we develop into an actual compute supplier, our firm’s worth will not be sufficient to get us the a whole bunch of thousands and thousands of {dollars} wanted to spend money on constructing information centres. If we did solely fairness, we disappear when the cash is gone. But when we really financial institution it on GPUs as collateral, they will take the GPUs away and put it in another information middle.”
