A French startup has raised a hefty seed funding to “rearchitect compute infrastructure” for builders wanting to construct and prepare AI functions extra effectively.
FlexAI, as the corporate is 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 straight underneath Elon Musk); Zoox (earlier than Amazon acquired the autonomous driving startup); and, most just lately, 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 just lately filling the CTO function at French startup Lifen, which develops digital infrastructure for the healthcare trade.
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 know what Tripathi and Kilani are trying with FlexAI, it’s first price understanding what builders and AI practitioners are up in opposition to by way of accessing “compute”; this refers back to the processing energy, infrastructure and assets wanted to hold out computational duties equivalent to processing information, working algorithms, and executing machine studying fashions.
“Utilizing any infrastructure within the AI area is advanced; 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 the best way to construct infrastructure earlier than you should use it.”
In contrast, the general public cloud ecosystem that has advanced these previous couple of a long time serves as a high quality instance of how an trade 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 wish to write an utility, 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 may’t do this with AI compute right this moment.”
Within the AI sphere, builders should determine 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 solely answerable for organising. If a GPU or community fails, or if something in that chain goes awry, the onus is on the developer to type it.
“We wish to convey AI compute infrastructure to the identical stage of simplicity that the overall function cloud has gotten to — after 20 years, sure, however there isn’t any motive why AI compute can’t see the identical advantages,” Tripathi stated. “We wish to get to some extent the place working AI workloads doesn’t require you to change 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 business product later this 12 months. It’s principally a cloud service that connects builders to “digital heterogeneous compute,” that means that they’ll run their workloads and deploy AI fashions throughout a number of architectures, paying on a utilization foundation slightly 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 principal 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 more than $2 trillion.
LLMs at the moment are pouring out of the know-how trade, 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 at all times make sense and will be prohibitively costly; that is why AWS has been dabbling with time-limited leases for smaller AI initiatives. However renting continues to be renting, which is why FlexAI desires to summary away the underlying complexities and let prospects entry AI compute on an as-needed foundation.
“Multicloud for AI”
FlexAI’s start line is that almost all builders don’t actually look after probably the most half whose GPUs or chips they use, whether or not it’s Nvidia, AMD, Intel, Graphcore or Cerebras. Their principal concern is with 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 smart for that specific job, taking good care of the all the required conversions throughout the completely 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 just centered on constructing, coaching and utilizing fashions,” Tripathi stated. “We deal with every thing beneath. The failures, restoration, reliability, are all managed by us, and also you pay for what you employ.”
In some ways, FlexAI is getting down to fast-track for AI what has already been taking place within the cloud, which implies greater than replicating the pay-per-usage mannequin: It means the flexibility to go “multicloud” by leaning on the completely 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’ll set that throughout the FlexAI platform to get the utmost quantity of compute bang for his or her buck. This may imply going by way of Intel for cheaper (however slower) compute, but when a developer has a small run that requires the quickest attainable output, then it may be channeled by way of Nvidia as a substitute.
Beneath the hood, FlexAI is principally 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, but it surely probably does imply that to a big extent — with Intel and AMD fighting for GPU scraps left in Nvidia’s wake — there’s a big incentive for them to play ball with aggregators equivalent 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 likely be very comfortable,” 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 centered squarely on Nvidia {hardware}.
“I wish to get AI compute to the purpose the place the present normal function cloud computing is,” Tripathi famous. “You may’t do multicloud on AI. It’s a must to choose particular {hardware}, variety of GPUs, infrastructure, connectivity, after which preserve it your self. In the present day, that’s that’s the one method to truly get AI compute.”
When requested who the precise launch companions are, Tripathi stated that he was unable to call all of them on account of an absence of “formal commitments” from a few of them.
“Intel is a robust accomplice, they’re undoubtedly offering infrastructure, and AMD is a accomplice that’s offering infrastructure,” he stated. “However there’s a second layer of partnerships which are taking place with Nvidia and a few different silicon firms that we aren’t 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 geared up 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 turned centered 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 straight underneath Elon Musk for his final six months after two individuals above him abruptly left the corporate.
“At Tesla, the factor that I discovered and I’m taking into my startup is that there aren’t any constraints aside from science and physics,” he stated. “How issues are performed right this moment just isn’t the way it ought to be or must be performed. You need to go after what the precise 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 huge black packing containers with metallic shielding and casing round it, to search 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 an enormous metallic 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 likely be funded by debt financing, constructing on a latest pattern that has seen rivals within the area including CoreWeave and Lambda Labs use Nvidia chips as collateral to safe loans — slightly than giving extra fairness away.
“Bankers now know the best way to use GPUs as collaterals,” Tripathi stated. “Why give away fairness? Till we change into an actual compute supplier, our firm’s worth just isn’t sufficient to get us the a whole bunch of tens of millions of {dollars} wanted to put money into constructing information centres. If we did solely fairness, we disappear when the cash is gone. But when we truly financial institution it on GPUs as collateral, they’ll take the GPUs away and put it in another information heart.”
