Alembic Applied sciences has raised $145 million in Sequence B and progress funding at a valuation 13 occasions larger than its earlier spherical, betting that the following aggressive benefit in synthetic intelligence will come not from higher language fashions however from proprietary knowledge and causal reasoning.
The San Francisco-based startup, which builds AI techniques that establish cause-and-effect relationships quite than mere correlations, is utilizing a good portion of the capital to deploy what it claims is likely one of the quickest privately owned supercomputers ever constructed — an Nvidia NVL72 superPOD that may energy its enterprise-grade causal AI fashions.
The funding, led by Prysm Capital and Accenture with participation from Silver Lake Waterman, Liquid 2 Ventures, NextEquity, Mates & Household Capital and WndrCo, positions Alembic amongst a choose group of well-funded AI laboratories reworking how companies make multimillion-dollar selections.
The funding spherical and the corporate's strategic route mirror a broader shift going down in enterprise AI because the efficiency hole between competing giant language fashions narrows. Whereas startups and tech giants have poured billions into constructing ever-larger chatbots, Alembic is pursuing a special thesis: that the actual worth in AI will accrue to techniques that may course of personal company knowledge to reply questions that generic fashions can not.
"As highly effective synthetic intelligence fashions more and more converge in functionality, the important thing aggressive benefit shifts to proprietary knowledge," mentioned Tomás Puig, Alembic's founder and chief govt, in an interview with VentureBeat. "Getting an actual edge isn't about utilizing the most effective LLM; it's leveraging the distinctive data rivals can't entry."
Puig illustrated the issue going through enterprise executives: "Think about I run a CPG firm and I set up the newest ChatGPT. I ask, 'Hey, ChatGPT, give me a method for how one can enhance my income share within the northeast.' Then your competitor down the street asks the very same query. How a lot hassle are you in after they get the very same reply?"
How a broke startup on Mac Execs found a breakthrough that modified every thing
The dramatic valuation enhance—from roughly $50 million on the Sequence A to roughly $645 million now, in line with folks conversant in the matter — displays a basic transformation in Alembic's expertise and market positioning since its earlier funding spherical.
When the corporate raised its Sequence A in early 2024, it was primarily a sign processing and correlation analytics firm targeted on advertising and marketing measurement. "Causal didn’t exist as a expertise for us until after the Sequence A," Puig instructed VentureBeat. The corporate was so resource-constrained that it couldn't even run simulations to check whether or not its causal fashions would work.
The breakthrough got here after the Sequence A when the corporate lastly had sufficient capital to check its theories. "We had been so broke that we couldn't even run the simulation to see if it labored," Puig recalled. Once they did run the checks — initially on an "military of Mac Execs" as a result of they didn't but have GPU infrastructure — they found one thing surprising: their causal mannequin labored not only for advertising and marketing analytics however throughout just about any enterprise area with time-series knowledge.
"We began including capabilities as clients requested them, which was simply smart—iterative," Puig defined. "We discovered the mannequin works throughout an enormous majority of knowledge universally. What we thought is likely to be a mannequin for a particular vertical ended up being a full, generalized foundational mannequin."
That discovery remodeled Alembic from a advertising and marketing expertise vendor into an organization constructing what Puig describes as "the whole central nervous system of the enterprise throughout all verticals — not simply gross sales, advertising and marketing, provide chain, finance, and past."
Why cause-and-effect AI issues greater than correlation for enterprise decision-making
Causal AI is a essentially completely different method from the correlation-based analytics that dominate most enterprise intelligence instruments and even many AI techniques. The place conventional analytics would possibly present that social media engagement correlates with gross sales will increase, causal AI can decide whether or not the social media exercise really brought on the gross sales raise — or whether or not each had been pushed by some third issue, like a viral information occasion.
The excellence issues enormously for executives making finances allocation selections. "Most companies are usually not brief on knowledge," Puig mentioned. "They’re brief on solutions."
For Alembic's clients, which now embrace Delta Air Strains, Mars, Nvidia and a number of other Fortune 500 corporations throughout monetary companies, expertise and client packaged items, the platform can reply beforehand unanswerable questions on advertising and marketing effectiveness, operational effectivity and strategic investments.
"Alembic's capability to attach advertising and marketing publicity on to enterprise outcomes—with pace, precision and granularity—is what made this relationship so transformative for us," mentioned Alicia Tillman, chief advertising and marketing officer at Delta Air Strains. "Not like conventional measurement instruments, Alembic gave us a unified view throughout channels and campaigns, unlocking insights we merely couldn't entry earlier than."
The airline used Alembic to quantify the income raise from its Group USA Olympics sponsorship inside days of activation, instantly linking model actions to ticket gross sales—a sort of measurement that has eluded entrepreneurs for many years. Conventional attribution fashions both ignore brand-building fully or assign it obscure "consciousness" metrics that don't translate to monetary impression.
"It's very transformative," Puig mentioned of the shopper impression. "What's fascinating is that executives themselves are the customers of our software program and our outputs. It's not a instrument utilized by a single marketing campaign supervisor."
Contained in the two-story liquid-cooled supercomputer that actually melted GPUs
Alembic's determination to take a position closely in owned computing infrastructure quite than depend on cloud suppliers stems from each the technical calls for of its causal fashions and the intense knowledge sensitivity necessities of its enterprise clients.
The corporate is deploying an Nvidia NVL72 superPOD — a large liquid-cooled system outfitted with Nvidia's most superior Blackwell graphics processing items — in partnership with knowledge heart operator Equinix in San Jose, Calif. In response to Puig, Nvidia knowledgeable Alembic that it’s the solely non-Fortune 500 firm on the planet to function such a system.
The necessity for this stage of compute stems from how Alembic's fashions work. Not like giant language fashions which can be educated as soon as on historic knowledge after which deployed, Alembic's system makes use of "on-line and evolving" fashions constructed on spiking neural networks — brain-inspired architectures that constantly be taught as new knowledge arrives.
"It creates itself as you feed it knowledge, like human evolution," Puig defined. "The mannequin is singular, however it finally ends up creating a special mind for each single firm."
This steady studying occurs at huge scale. When a buyer brings in knowledge, Alembic's system routinely permutates via billions of doable mixtures of how that knowledge might be analyzed — testing each conceivable solution to slice metrics and dimensions to search out the strongest causal alerts. That stage of computation requires what Puig calls "F1 automobile" infrastructure quite than the "manufacturing Porsche" supplied by cloud suppliers.
The corporate writes customized CUDA code and low-level GPU kernels optimized particularly for causal inference workloads — optimizations that aren't doable on commonplace cloud configurations. The method has confirmed so demanding that Alembic famously as soon as melted down its GPUs by pushing them past their thermal limits. "We actually simply drive these circuits so arduous that we want the F1 automobile model and we now have to have entry to it," Puig mentioned.
The transfer to liquid-cooled techniques addresses that drawback, however it additionally permits Alembic to run workloads that will price orders of magnitude extra on cloud platforms. "We did the maths—if we had been to purchase only one subsection of our compute from AWS, it will be $62 million a yr," Puig mentioned. Proudly owning the infrastructure prices "a fraction of that."
The supercomputer technique serves one other essential goal: knowledge sovereignty. Lots of Alembic's clients — significantly in monetary companies, client packaged items and controlled industries — have contractual prohibitions towards placing delicate knowledge on Amazon Internet Companies, Microsoft Azure or Google Cloud.
"CPG corporations don’t want any knowledge to exist on Amazon, ever," Puig mentioned. "They merely received't enable it. Some clients refuse to make use of Microsoft, others keep away from completely different suppliers. And sure banks and monetary establishments are legally prohibited from utilizing cloud platforms in any respect."
By working its personal infrastructure in impartial knowledge facilities, Alembic can serve clients who would by no means take into account cloud-based analytics — a aggressive moat that will be tough for hyperscale cloud suppliers to duplicate.
How Jensen Huang learn a information article and adjusted Alembic's future
Alembic's relationship with Nvidia illustrates each the startup's technical ambitions and the way the chip big helps promising AI corporations. Nvidia is Alembic's founding enterprise buyer, unique supercomputing companion and a key technical collaborator — although notably not an investor.
The connection started in an unlikely means. After Alembic introduced its Sequence A funding in early 2024, Nvidia co-founder and CEO Jensen Huang learn the VentureBeat protection and emailed his workers suggesting they discover the corporate, in line with Puig. As a result of Alembic didn't but have a contact kind on its web site, an Nvidia director reached out by way of LinkedIn.
The partnership almost foundered on a primary constraint: computing capability. After Alembic delivered its first causal evaluation — which took weeks to generate on an array of Mac Execs — Nvidia requested if they may produce weekly studies. "I mentioned no, as a result of it took weeks on this military of machines," Puig recalled.
When Alembic mentioned they may do it with GPUs however couldn't safe the required compute — cloud suppliers on the time required committee approvals and supplied two- to six-week lead occasions with no ensures — Nvidia intervened instantly. The chip maker organized for Equinix to supply a personal cage in Northern Virginia with ample energy capability and helped Alembic supply its first H100 GPU cluster.
"With out that, the corporate would by no means have existed," Puig mentioned. "We couldn't get the compute within the configuration we would have liked anyplace else."
The partnership has since deepened. Alembic makes use of Nvidia's AI Enterprise software program suite, together with specialised libraries like cuGraph for graph processing and TensorRT for high-speed inference. The tight integration, Puig mentioned, permits "our analysis groups to leverage multi-exaflop-level compute and Nvidia's algorithmic software program stack. This integration is one in every of our secret weapons: we spend extra time on breakthrough analysis and arithmetic and fewer time on repetitive low-level engineering."
Nvidia's assist prolonged past expertise. When Alembic stored destroying GPUs beneath excessive workloads — pushing chips so arduous that thermal stress cracked circuit boards — Nvidia fast-tracked the startup's entry to next-generation liquid-cooled techniques. "The humorous motive we received [the NVL72]," Puig mentioned, "is as a result of once we melted the chips, Nvidia was actually aggravated with how usually they needed to service our guarantee."
From Olympics sponsorships to viral sweet moments: How Fortune 500s measure what was unmeasurable
Alembic's buyer roster has expanded quickly as enterprises search methods to measure AI and advertising and marketing investments that conventional analytics can not seize. The corporate now works with Delta Air Strains, Mars, a number of Fortune 500 expertise and monetary companies corporations, and Texas A&M College's athletics program.
The use circumstances span far past Alembic's authentic advertising and marketing focus. Mars used the platform to measure the gross sales impression of fixing sweet shapes for themed promotions. A Fortune 500 expertise firm expanded its gross sales pipeline by 37% utilizing Alembic's attribution fashions. Monetary companies corporations are utilizing it to attach CEO public appearances and co-marketing expenditures to precise fund flows.
"Alembic helped us transfer previous impression counts to point out what really drove net-new funding," mentioned the top of co-marketing at a Fortune 200 monetary companies firm. "For the primary time, we might see how our CEO within the public eye and our co-marketing {dollars} with exchanges translated into actual fund flows."
For Mars, the power to measure beforehand unmeasurable actions has remodeled decision-making. "We’re utilizing math to liberate creativity," mentioned Gülen Bengi, lead world chief advertising and marketing officer for Mars and world chief progress officer for Mars Snacking. "Our followers and communities create billions of natural conversations and content material about our manufacturers. When a viral second occurs, we usually comprehend it's directionally optimistic, however we are able to't attribute the gross sales uplift or its place within the buyer journey. Alembic's Causal AI is a breakthrough, permitting us to maneuver past correlation to see precisely how that natural dialog created a sequence that instantly impacted gross sales."
The platform can predict income, shut charges and buyer acquisition as much as two years upfront with 95% confidence, in line with Puig. "What they had been doing earlier than was they really actually didn’t find out about sure issues," he mentioned, describing how clients beforehand estimated the worth of stadium naming rights or main sponsorships with out ever measuring precise greenback impression. "Now you may go and be prefer it had this impact on this a lot P&L, and that is the place it's flowing, and you’ll know inside days or close to actual time."
Why Google, Meta and Nielsen can't simply replicate what Alembic constructed
Alembic operates in a aggressive panorama that features conventional advertising and marketing measurement distributors like Nielsen, analytics platforms from Google and Meta, and rising AI-powered analytics startups. However Puig argues the corporate has constructed structural benefits that will be tough to duplicate.
First, the corporate's causal fashions depend on proprietary arithmetic developed over years and guarded by patents. "You would need to begin from scratch," Puig mentioned. "This isn’t like an LLM that makes use of a transformer that has a paper, and you possibly can try to recreate. You'd really need to go and recreate the methodology from scratch."
Second, the huge computing necessities create a pure barrier. Alembic operates at "foundational mannequin ranges of compute, not like even one thing you’d run from [AWS] Sagemaker," Puig mentioned. "We're speaking about a whole lot of tens of millions of {dollars} a yr" in equal cloud prices.
Third, the information sovereignty necessities of enterprise clients create alternatives for impartial third events that hyperscale cloud suppliers battle to deal with. As one enterprise capital investor famous, enterprises more and more fear about placing strategic knowledge into techniques owned by potential rivals.
Lastly, Alembic's capability to work with messy, fragmented knowledge displays years of engineering that preceded its causal AI breakthrough. "The primary 4 [or] 5 years of the corporate's life was constructing that big sign processor that handled messy knowledge," Puig mentioned. "We’d not have the ability to do it if we had not taken all that point."
Why Alembic's contrarian wager on personal knowledge might reshape enterprise AI
The $145 million funding spherical validates a contrarian wager in an AI panorama dominated by the race to construct ever-larger language fashions. Whereas OpenAI, Anthropic and others compete on whose chatbot can write higher code or reply extra trivia questions, Alembic is constructing infrastructure for a special sort of intelligence — one which understands trigger and impact within the messy, proprietary knowledge that defines every firm's distinctive aggressive place.
The corporate's evolution from a bootstrapped startup operating simulations on Mac Execs to working one of many world's quickest personal supercomputers mirrors the broader maturation of enterprise AI. Because the expertise strikes from experimentation to mission-critical deployment, corporations want greater than general-purpose fashions educated on public knowledge. They want techniques that may course of their personal data to reply questions their rivals can not.
Puig's thesis — that personal knowledge turns into the important thing differentiator as public fashions converge — resonates with how different applied sciences developed. Search engines like google commoditized entry to public data, making proprietary knowledge extra precious. Cloud computing made infrastructure a utility, elevating the significance of what you construct on prime of it. If giant language fashions equally converge in functionality, the aggressive benefit flows to whoever can greatest extract intelligence from knowledge others can not entry.
The corporate is already testing its expertise past advertising and marketing analytics. Pilots are underway in robotics, the place causal fashions might assist autonomous techniques perceive how actions result in outcomes. New product strains are launching, together with the GPU-accelerated database that clients are shopping for individually. The ambition, Puig mentioned, is to change into "the central nervous system" of the enterprise — the layer that connects trigger and impact throughout each enterprise operate.
Whether or not Alembic can ship on that imaginative and prescient stays to be seen. The corporate operates in advanced enterprise environments the place gross sales cycles are lengthy and integration challenges are vital. Rivals aren't standing nonetheless, and the technical moats that defend it at the moment might erode as causal AI methods change into higher understood.
However for now, Alembic occupies a novel place. It has marquee clients attaining measurable outcomes. It has infrastructure that will price a whole lot of tens of millions to duplicate on cloud platforms. It has proprietary arithmetic refined over years of coping with messy enterprise knowledge. And it has $145 million to scale what Puig describes as a basic shift from correlation to causation.
In his interview with VentureBeat, Puig drew a parallel to quantitative hedge funds that use arithmetic to realize buying and selling benefits that general-purpose AI can not match. "ChatGPT nonetheless can't equal Renaissance Applied sciences," he mentioned, referring to the secretive agency that has generated historic returns via quantitative fashions.
The comparability captures Alembic's core perception: that in a world the place everybody has entry to the identical general-purpose AI, sustainable benefit comes from specialised techniques that perceive the cause-and-effect relationships hiding in your knowledge. It's a wager that the way forward for enterprise AI appears to be like much less like a common chatbot and extra like a personal intelligence engine — one which, to Puig's authentic level, prevents your competitor from getting the identical reply after they ask the identical query.
