It has been a whirlwind yr for the Open AI-backed, generative AI authorized tech startup Harvey, which went from a $5 million seed round in November 2022 to a $21 million Series A in April 2023 to an $80 million Sequence B in December 2023 at a valuation of $715 million.
It was a yr that included some huge wins, together with the decision in February 2023 by Allen & Overy, one of many world’s largest legislation companies, to combine Harvey into its international apply, the place it may very well be utilized by the agency’s greater than 3,500 attorneys throughout 43 workplaces working in a number of languages.
Only a month after that, Harvey and PwC announced a global partnership to offer PwC’s Authorized Enterprise Options professionals unique entry among the many Huge 4 to Harvey’s AI platform. Extra just lately, in what they described as a “vital step past the exclusivity settlement,” Harvey and PWC announced a strategic alliance, that additionally included Harvey investor OpenAI, to coach and deploy basis fashions for tax, authorized and human sources.
In September, one other main agency, Macfarlanes, introduced that it would roll out Harvey firmwide, after an preliminary pilot program, and final month, Forbes named Harvey to its AI 50, recognizing essentially the most promising privately-held AI firms – the one legal-specific AI on the checklist.
However even with such dramatic traction for an organization that’s nonetheless lower than two years outdated, there has remained an air of secrecy round Harvey. The product continues to be in an early-access part; few, aside from choose early-access clients, have seen the Harvey product; and the corporate’s founders, Winston Weinberg, its CEO, and Gabriel Pereyra, its president, have given few media interviews.
However that’s about to vary, the 2 founders advised me in an interview earlier this week. They are going to be popping out of the early-access part throughout the third quarter of the yr and launching variations that they are saying will probably be extra reasonably priced to companies of assorted sizes, relying on their wants.
Additionally they say that they are going to be exhibiting the product extra typically, attending extra business conferences, and talking extra typically with the press.
From Customized to Industrial
A part of the explanation they’ve been so stealthy, Weinberg and Pereyra say, is that they’ve been nose-to-the-grindstone constructing extremely personalized fashions for the massive legislation companies they serve.
Customization of its AI mannequin has been Harvey’s trademark, in a way, and a key differentiator from different widespread authorized AI merchandise, most notably CoCounsel, the AI authorized assistant developed by Casetext and purchased by Thomson Reuters.
Extra just lately, nonetheless, Harvey has been constructing {custom} fashions and associated merchandise that may be bought commercially to a number of clients. These embody the fashions it’s constructing with PWC for tax, authorized and human sources; new case legislation analysis fashions it’s growing in partnership with OpenAI; and a brand new Vault product that may enable clients to use generative AI capabilities to giant doc collections.
It additionally just lately launched its product on the Microsoft Azure Market, the place it’s providing a Harvey on Azure model of its product.
“Deploying on Microsoft Azure is a key milestone for Harvey,” Weinberg, who’s Harvey’s CEO, mentioned in saying that launch. “This collaboration permits us to make use of Azure’s strong cloud capabilities to reinforce Harvey’s imaginative and prescient, making it extra highly effective and accessible for companies the world over.”
Later this yr, in a transfer designed to make Harvey extra accessible to a broader variety of attorneys, it’s going to start providing business entry to a few of its merchandise. It’s going to begin with its case legislation fashions, after which start providing bundles of its merchandise.
Clients may have the choice of selecting a bundle of merchandise that may embody its AI assistant, varied case legislation or specialised analysis fashions, its Vault for big doc collections, and {custom} fashions or initiatives.
There can even be prepackaged bundles that will probably be supplied at a reduced value.
Case Regulation Analysis
In keeping with Weinberg and Pereyra, a key step in Harvey’s transfer in the direction of broader business availability has been its partnership with OpenAI to construct custom-trained caselaw fashions. They’ve already performed this for U.S. legislation and can now be including different jurisdictions.
In in search of to develop a analysis answer, they discovered that merely fine-tuning a basis mannequin similar to GPT-4 or utilizing retrieval augmented era (RAG) was not enough to provide the extent of outcomes required for authorized work.
As a substitute, the case legislation system they constructed is a mix of a big basis mannequin pre- and post-trained on all of U.S. case legislation and a case legislation search system that the mannequin leverages.
It makes use of a mix of authorized particular information preprocessing, hybrid search, pre-training, post-training, multi-stage reasoning, retrieval and {custom} fine-tuned embeddings, and authorized particular reply postprocessing, Weinberg mentioned.
“At a excessive degree, the system we’ve developed performs authorized analysis very like an affiliate would, taking a posh analysis question and performing case legislation searches, analyzing the outcomes and finally synthesizing all the data to supply an correct outcome for the customers,” Weinberg mentioned.
“We’ve constructed quite a lot of legal-specific options for the search and reply system together with extracting quotation graphs, procedural posture, and reality patterns from circumstances to enhance search and detecting case hallucinations, inconsistent arguments, and situations of weak case help in solutions.”
This authorized analysis mannequin can be utilized for conventional analysis and also will have the ability to be used for extra complicated workflows, similar to cross-jurisdictional surveys, transient drafting, concern recognizing in giant units of discovery or investigative paperwork, and litigation danger evaluation.
Harvey additionally plans to companion with authorities entities to make use of these fashions to advance entry to justice by making case legislation extra accessible.
Already, the corporate has partnered with court officials in Singapore to assist professional se litigants in small claims circumstances get solutions to their authorized questions with the intention to higher perceive their potential claims or defenses.
PWC Partnership
By its partnership with PwC, Harvey is growing a sequence of {custom} constructed fashions centered on the areas wherein PwC has area experience – tax, authorized and human sources. Whereas Harvey supplies the AI know-how, PwC supplies each the mental property and the area specialists to advantageous tune and practice these fashions.
As these fashions are developed, Harvey and PwC will collectively go to market with them, each promoting them by way of their very own channels. These will probably be bought a separate, standalone merchandise, not a part of the bundles described above.
Vault
The Vault product is being designed to allow clients to make use of generative AI to discover giant collections of hundreds of paperwork, both by asking pure language questions of the paperwork (“Ask Question”) or performing particular duties towards the set, similar to discovering and summarizing sure language (“Evaluation Question”).
For instance, Weinberg mentioned, over a set of 1,000 grasp service agreements, an Ask Question is likely to be, “Has the corporate ever executed an MSA with Oracle?” A Evaluation Question may very well be, “Create a chart exhibiting me each contract that has change-of-control provisions and, for those who do, inform me if the contract permits for termination on a change of management.”
Customized Fashions for Giant Companies
Even because it develops these new merchandise to makes its know-how extra broadly accessible, Harvey is constant to construct merchandise for big legislation companies.
Particularly, it’s constructing a platform that enables companies to securely practice generative AI programs on all their personal information, combine with their current authorized tech software program and workflows, and repeatedly study from their authorized workforce.
“Sadly, it isn’t so simple as coaching a single mannequin on all their paperwork,” Weinberg mentioned. “Doing so would lead to information leakage.”
“As a substitute, we’re constructing a set of instruments that enable legislation companies to coach, consider and deploy generative AI programs that respect information privateness, moral partitions, and shopper privateness whereas nonetheless being extremely correct and performant,” he mentioned.
For its largest companions, Weinberg mentioned, Harvey is constructing “hyper specialised” programs for his or her most complicated use circumstances.
With PwC, for instance, Harvey is constructing basis fashions in each tax jurisdiction that may reply complicated tax questions over tax codes and laws in addition to carry out tax due diligence and extra complicated scenario-based evaluations, Weinberg mentioned.
“This technique is built-in inside PwC’s broader tax apply and our fashions leverage PwC’s different third-party distributors, their IP, and their inside software program options and might produce experiences of their historic format.”
Weinberg mentioned that, given the complexity of such a venture, the event value might exceed $5 million, “however we’re beginning to discover methods to supply extra reasonably priced variations to our shoppers and hope to take action extra as we scale.”
Hiring A great deal of Attorneys
Once they based Harvey in 2022, Weinberg was a former affiliate at legislation agency O’Melveny & Myers and Pereyra was a former analysis scientist at DeepMind and machine studying engineer at Meta AI.
Once we spoke this week, they mentioned that one of the fascinating elements of their progress over the previous yr has been studying to run an organization of that scale.
However they agreed that one of many elements they’re most pleased with is their hiring, which has been primarily of engineers and attorneys. In actual fact, of the corporate’s 120 workers at present, nearly half are attorneys – lots of them attorneys with huge agency or company pedigrees – who’ve been introduced on as area specialists.
Whereas it’s not uncommon for a authorized tech startup to rent attorneys, it’s usually for both a non-lawyer position as a product supervisor or salesperson, or it’s for a lawyer position as an inhouse counsel.
However Weinberg mentioned that the majority of Harvey’s attorneys are working in analysis roles – to not analysis the legislation, however to analysis attorneys’ workflows and processes round particular duties.
“They’re saying, ‘How would I’ve performed this process once I was at Latham or I used to be at Kirkland? How did I do disclosure schedules? How did I do case legislation analysis? How did I do complicated summarization? How did I draft a short?’ They’re taking all of these duties after which mapping them onto AI.”
Weinberg and Pereyra speak about this as “course of information” – the method by which a lawyer performs a process. When a lawyer sees a case for the primary time, or a merger settlement, or an NDA, the lawyer has a course of for analyzing that doc. That’s the form of information they need to construct into Harvey, and why they’re hiring so many attorneys.
“Attorneys must be skilled for a few years to do that, and that information – that course of information – isn’t publicly accessible anyplace,” Weinberg mentioned.
“The factor that’s crucial is the way you practice the AI, and also you want a mix of area specialists and AI engineers,” Weinberg mentioned. “I believe that there aren’t tons of firms which might be doing that on the software layer in any vertical proper now – I believe the factor that’s lacking in lots of these firms is the area specialists.”
However whereas a lot of the main focus to this point of those attorneys on its employees has been on constructing {custom} fashions for big companies, Weinberg and Pereyra mentioned they needed to broaden entry to their know-how, which is the explanation for the brand new merchandise they are going to be launching within the third quarter.
“Quite a lot of the companies on the market, they’ll’t afford to do these giant, huge customizations,” Weinberg mentioned, “so let’s construct issues for them that they’ll additionally use and which might be nice as nicely.”
That commercialization will probably be rolled out in levels, starting with the case legislation fashions and the Vault product. Subsequent will come the widely accessible bundles of merchandise. In the direction of the top of this yr or early subsequent yr, they’ll introduce a self-service mannequin.
In fact, all of the whereas, they’ll proceed to supply customizations for big enterprise clients.
A query I hear typically is how Harvey compares to CoCounsel, the Thomson Reuters authorized AI assistant, and so I put that query to Weinberg and Pereyra.
There are two foremost variations, they mentioned. One is the customization they’re doing for bigger legislation companies, one thing that TR doesn’t supply with CoCounsel.
The opposite is the strategy they’re taking to constructing their product. On the backend, they’ve skilled a number of fashions for particular duties after which, successfully, chained them collectively, so there’s a mannequin for clause extraction and a special mannequin to deal with a particular sort of question.
“It’s truly just like how a legislation agency works, the place you have got a request from the shopper after which the companion breaks that request into ten different requests and sends it to a specialised one who does that process, after which all of them mix these collectively,” Weinberg mentioned. “That’s what’s taking place on the again finish.”
Dedication to A2J
I discussed above Harvey’s partnership with the courts in Singapore to help professional se litigants there, and Weinberg and Pereyra say they’re dedicated to serving entry to justice on an excellent broader scale.
They mentioned they’ll give their product without spending a dime to court docket programs or A2J organizations. “That is one thing we need to do much more and within the U.S. too, to construct these programs after which give them to the court docket without spending a dime.”
