BenchSci: Reimagining Pre-Clinical Drug Discovery
How AI can Accelerate Drug Development Cycle
Welcome to the 6th Network Effects Newsletter.
If you're new here, this newsletter is all about unpacking the vision, strategy, and execution behind the world’s leading tech companies.
Today, we’re exploring BenchSci, which was founded in 2015 by Tom Leung (CSO), David Chen (CTO), Elvis Wianda (CDO), with Liran Belenzon (CEO) joining in 2016
Let’s dive in.
📝 Overview
BenchSci is an AI-powered reagent intelligence platform that transforms biomedical literature into experiment-specific insights. BenchSci focuses on antibodies, representing 88% of all research reagents used in preclinical drug development. Given that 30-40% of drug discovery costs are concentrated in preclinical R&D, BenchSci addresses a critical pain point by enabling more efficient, evidence-based experimentation.
The company’s flagship product, ASCEND, is a machine learning platform that decodes complex scientific text and figures to surface actionable insights across millions of published experiments. ASCEND is currently used by over 49,000 scientists worldwide, supporting key functions such as target identification, biomarker discovery, and hypothesis generation.
Within BenchSci’s top 10 enterprise accounts, ASCEND has driven measurable R&D efficiency gains: users uncovered novel targets or disease indications in 22% of key projects, while reducing unnecessary experimentation by 40%, materially accelerating time-to-insight in the preclinical research cycle.
📌 Thesis 1 - Markets Ripe for Innovative Disruptors
Biopharma’s innovation engine is fundamentally broken. Over the past three decades, R&D costs have increased more than 6x while new drug approvals have remained flat, a paradox often referred to as Eroom’s Law (Moore’s Law in reverse).
Until recently, clinical operations (e.g., trial design, patient recruitment) have been the focal point for digital transformation, platforms like Medidata or Veeva dominate that segment. In contrast, preclinical research has remained largely manual and fragmented: scientists sift through thousands of papers, manually compare reagent options, and design experiments in isolation. ASCEND is among the first true horizontal AI infrastructures purpose-built for preclinical workflows, encompassing target ID, reagent selection, experimental planning, and risk assessment. By automating literature mining, extracting structured insights from complex figures, and surfacing context-specific reagent recommendations, BenchSci demonstrably cuts experimental planning time by 30–50% and reduces failed experiments by up to 40%.
Furthermore, there is a growing competitive pressure from emerging BioPharma (EBP) to compete with incumbents. It creates an appetite for BioPharmas to invest in alternative platform solutions to obtain an edge over their competitors.
Adopters of the ASCEND platform have shown real value through reduced unnecessary experimentation and an increase in productivity. For example, Novartis has saved over $14M by deploying BenchSci by avoiding unproductive experimental dead ends.
📌 Thesis 2 – Data Flywheel Translate to Lower Error Rates
Over the past decade, BenchSci has formed a running virtuous cycle of data partnership with 200+ vendor catalogues and private publisher content (e.g., Springer, Wiley, Oxford), covering over 10M+ scientific publications, 47,000+ validated independent datasets and 6.7M+ reagents.
This rich, proprietary data set is not easily replicable and forms the core of BenchSci's competitive edge. Beyond that, BenchSci creates a dynamic flywheel, where this proprietary data fuels BenchSci's ability to deliver superior insights, driving increased platform usage and stickiness among researchers. This influence further encourages these publications to partner with BenchSci, enriching the platform with valuable content, attracting more users, and enhancing its overall value in a self-reinforcing loop.

Layering on customers’ proprietary internal data (e.g., Electronic Lab Notebooks, reagent purchasing histories) further personalizes and enriches the platform, increasing switching costs and embedding ASCEND deeper into R&D workflows.
While broader AI drug-discovery platforms (e.g., Recursion, Insitro) are moving upstream, their primary focus remains on molecule generation and late-stage optimization. BenchSci’s specialization in experimental design and reagent intelligence has allowed it to build deep expertise in preclinical R&D, with deep network effects from the usage of proprietary data and the performance of its intelligence platform. BenchSci can maintain its leadership position, even as horizontal players expand into the preclinical space.
"If you’re in a very niche domain and you’re sitting on a corpus of data relevant to that domain, you will have longevity.
🌱 Genesis Story
In 2008, the U.S. government mandated the NIH Public Access Policy, requiring all NIH-funded research to be freely available through PubMed Central. By 2015, this repository had amassed over 1.2 million peer-reviewed studies, however, the vast majority of research findings remained buried, inaccessible to traditional methods of search and interpretation due to the sheer volume and the complexity of scientific figures and languages
Recognizing this gap, Tom Leung, then a PhD candidate at the University of Toronto, had an idea to leverage AI to learn from scientific papers and help build, test and validate solutions to the antibody reproducibility crisis. To build this platform, Leung recruited David Chen and Elvis Wianda, fellow researchers with deep expertise in data science and AI.
In 2016, Liran Belenzon, who was working for the Creative Destruction Lab (CDL), a startup accelerator focused on Machine Learning, reached out to recruit to BenchSci team to apply for the accelerator program. The team was successful in joining CDL, and Liran started working with them to support their commercialization, then joined as co-founder and CEO.
In 2017, BenchSci launched its first application, AI-Assisted Antibody Selection, to help scientists reduce experimental failure. The solution used both experiment-specific text ML and proprietary vision ML models that could understand the type of experiment being conducted. Next, our team expanded the technology to guide the selection process of many reagents.

🏢 Markets
BioPharma R&D
Progress in drug development, measured by the number of new drugs approved each year, has been slowing steadily over the past 50 years—a phenomenon known as Eroom’s Law (Moore’s Law in reverse). Despite the explosion of technological innovation elsewhere, biopharma has struggled to translate scientific breakthroughs into new therapies at scale.
Meanwhile, R&D investment by major pharma companies has ballooned from $86B in 2013 (17.5% of sales) to $190B in 2023 (25.2% of sales), reflecting intensifying pressure to find the next wave of blockbuster drugs. This escalating investment, combined with stagnant productivity, creates an acute need for solutions that can drive efficiency and results.
About 30-40% of the drug discovery cost is in preclinical R&D, which translates to over $60B spent at the early development stage for drug discovery, providing a large opportunity for BenchSci to compete.
Drug Discovery Stage
At the front end of the drug development pipeline, the challenge is even more pronounced. Biopharma companies today collect 7x more investigational drug data than they did two decades ago. Yet, only 5–6% of preclinical projects advance to clinical trials. Early-stage research remains heavily reliant on manual, siloed processes that are ill-suited for managing the complexity and volume of modern data.
"…While we're amazing at generating a lot of information, unfortunately, we're not very good at generating a lot of knowledge”
AI in Life Sciences
The application of machine learning (ML) and natural language processing (NLP) techniques across the pharmaceutical value chain is still in its early innings. Most of the focus to date has been downstream—optimizing clinical trial management, patient recruitment, or drug commercialization. However, the largest unrealized value likely resides upstream, in preclinical R&D, where better hypothesis generation, experiment design, and risk identification could fundamentally alter the cost and success curves.
Companies can accrue benefits from AI in two ways:
Accelerate the Development Cycle
Achieve Cost Efficiency with the Development Process
The current landscape for AI in Life Science is quite premature, however, two major waves are shaping the TechBio stack:
Data Infrastructure Evolution: → This is where BenchSci Plays
Life sciences data is fragmented, similar to the early tech data stack. Before AI can have a real impact, the industry must integrate vast, multi-modal datasets (genomics, clinical trials, etc.) and modernize legacy platforms.AI/ML Innovation Cycle:
Advances like AlphaFold and Peptone highlight how tightly coupled data and AI are in life sciences. Rapid feedback loops between experiments and models are essential to improve predictions and accelerate drug discovery and development.
Right now, we are at the juncture of realizing we need the ability to engineer bio, and a fuller ability to engineer it (i.e., we’re still in the installation phase). In the tech industry, the analog period for the web led to the creation of massive companies like Amazon and Google. Given the power of the combined trends — and the scale of the challenges and massive market of healthcare — we should expect to similarly see the rise of a few potentially trillion-dollar companies at scale: the equivalent of a Bio GAFA, finally.
⚔️ Competitions
BenchSci is operating at the frontier of preclinical R&D enablement, but it is not alone. The competitive landscape can be divided into three broad categories:
AI Drug Discovery Platforms (Cyclica, Owkin, PostEra)
These firms apply AI to later stages of the drug discovery continuum (e.g., molecule generation, target-disease association). While their core competencies today differ (small molecule design, clinical prediction), the underlying technology trajectories are converging.
The real risk is platform creep. If players like Owkin (which is expanding into target identification) move upstream aggressively, BenchSci’s moat will rely heavily on maintaining and expanding its corpus advantage and embedding ASCEND deeper into pharma R&D operations.
Scientific Intelligence Platforms (Bioz, Zageno, Eagle Genomics)
These platforms provide AI-driven tools for reagent selection, procurement, or data integration, but typically focus on isolated stages of the research workflow. Many rely on citation aggregation or procurement simplification without deeply embedding into experimental hypothesis generation or validation. Others offer graph-based solutions but are often services-heavy and less scalable.
Data Marketplaces (Antibodies.com, Antibodies-online, Biocompare, BIOZOL, IHC World)
These players aggregate reagent offerings but lack meaningful computational insight layers. They offer access to catalogues and data, but not experiment-specific recommendations. Switching costs remain low, and the decision-making burden is placed on the researcher. These sites may pose acquisition targets for downstream vertical integration, but do not currently challenge BenchSci’s strategic position.
⚙️ Business Model
BenchSci operates on a two-tiered SaaS model: one designed for academic users and one for enterprise pharmaceutical companies.
The academic tier allows researchers affiliated with educational institutions to access the platform, often with a limited set of features designed to accelerate experimental planning and reagent selection. This strategy helps BenchSci build early mindshare among future industry scientists while supporting open scientific innovation.
The enterprise tier targets large pharmaceutical, biotech, and life sciences companies. It provides a fully featured version of the ASCEND platform, including access to advanced applications like Selector, Navigator, Architect, and Defender, as well as enhanced AI assistants tailored to specific therapeutic areas and research stages.
Pricing for enterprise clients is typically structured as an annual subscription with a seat-based fee structure. Additional fees based on data integrations and customizations may apply as well
💰Valuations & Fundraising
Since its inception, BenchSci has raised over CAD $218M across multiple funding rounds. In May 2023, BenchSci announced its Series D ($95M) led by Generation Investment Management with participation from existing investors Inovia Capital, TCV, Golden Ventures and F-Prime Capital.
The lead investors for previous rounds include: Real Venture (Pre-Seed), Golden Venture (Seed), iNovia Capital (Series A & Series C), Gradient Ventures (Series B), TCV (Series C). At the beginning, BenchSci had also participated in the accelerator program by Creative Destruction Lab.
♟️ Key Opportunities
Growing Adoption of AI in Drug Discovery
The biopharma industry is increasingly investing in AI-driven preclinical innovation, with 13.5% of R&D budgets allocated to this area in 2024, up from 9.8% in 2021. As pharma companies invest more into technology for early-stage drug discovery, particularly target identification and experimental design, BenchSci’s ASCEND platform is uniquely positioned to streamline the process and improve success probabilities for its customers.
With a growing track record of large BioPharma success with BenchSci’s platform, in addition to the growing appetite for AI capabilities, BenchSci can accelerate its GTM strategy and build real business cases for customers.
Growing Market Players in EBP
Emerging Biopharma companies (EBPs) now account for a staggering 72% of the industry’s clinical pipeline (IQVIA, 2023). These firms are ramping up their R&D spend—$49B in 2023, a dramatic rise from $26B a decade ago—and face unique challenges as they lack the infrastructure of large pharma. As such, they are increasingly turning to external R&D enablement solutions like ASCEND, which provide scalable, turnkey applications (e.g., Selector, Navigator, Architect, Defender) that allow these companies to accelerate their experimental decision-making without the need for significant internal IT investment. BenchSci has a unique opportunity to capture a significant share of this market as EBPs continue to grow and diversify.
Expansion into Adjacent Vertical Markets
The ASCEND platform’s modularity positions it for expansion beyond its core preclinical R&D focus. There are clear opportunities for BenchSci to diversify into adjacent verticals, including:
Computational Drug Design: Extending BenchSci’s AI capabilities into early-stage drug design to further accelerate time-to-market
Companion Diagnostics: Providing critical insights into how biomarkers can guide personalized treatment options
Biomanufacturing Optimization: Enhancing production processes to reduce costs and improve the scalability of biologics
Translational Clinical Research: Leveraging preclinical insights to improve the transition to clinical trials, bridging the gap between bench and bedside
⚠️ Key Risks
Increasing Competition and Horizontal Platform Integration
BenchSci is competing in an increasingly crowded market. Companies like Recursion, Insitro, and Owkin are broadening their scope beyond preclinical experimental design to include full-stack AI-driven discovery platforms. If these players succeed in scaling horizontally, they could create greater competition against BenchSci's markets. Notably, Owkin raised $450M at a $ 1B+ valuation, signalling aggressive expansion into upstream R&D tools. If these competitors can scale across discovery, they may outpace BenchSci, reducing differentiation and limiting growth prospects.
Pharma’s Preference for Build over Buy
The industry’s largest players are opting to build proprietary solutions rather than relying on third-party vendors. Novartis’ Nerve Live and Roche’s internal R&D capabilities are examples of how large pharma is consolidating data science and multi-omics research in-house. If pharma companies replicate BenchSci’s core functionalities internally, they may erode demand for external solutions like ASCEND, which could lead to downward pressure on pricing or the loss of key accounts. This “build vs. buy” dynamic is an increasing risk that could limit BenchSci’s long-term scalability if larger customers decide to invest heavily in internal capabilities.
Slow Adoption Cycle with Long Sales Cycle
Despite the compelling ROI BenchSci offers, pharma remains a notoriously slow adopter of new technologies, particularly in the early R&D stages. A Pistoia Alliance survey in 2023 revealed that only 28% of pharma professionals were actively adopting AI in early-stage R&D, citing concerns over validation standards and reproducibility. This slow adoption is further compounded by the long sales cycles (12-24 months), which require considerable upfront investment in customer education, integration, and ongoing support. BenchSci will need to continue investing heavily in building strong relationships and demonstrating the ROI of its platform before it sees meaningful adoption at scale.
