The Automated Code Testing Revolution is Underway: Announcing the SapientAI-8VC Partnership
AI and automation have become essential components in the developer's toolkit, transforming the way we build software and offering the best hope yet of meeting the unrelenting demand for scale, speed, and reliability that has come to characterize the cloud-native era. Whether as engineers or investors, when attempting to identify the essential tools amid a sea of contenders, context is everything. This is doubly true for generating test code - a realization that helped to guide the formation of 8VC’s newest portfolio company, SapientAI.
The roots of today’s context-rich developer resources run deep. Autocompletion tools have been around since the 1960s, when Les Earnest pioneered programmatic spell checkers, while Alice Pascal included context-sensitive code completion in 1986. The advent of foundation model-powered developer tools, however, has finally ushered in a wholesale era of AI-assisted code authoring. Concurrently, the “shift left” phenomenon has concentrated more decision-making, as well as more responsibilities, with software developers. As testing and quality assurance have moved forward in the development process, bugs can be identified and eliminated sooner - but at substantial cost to developer time and attention.
Sapient offers a decisive answer to this conundrum, combining the power of foundation models with traditional lexical approaches to create the world's most comprehensive platform for developers to write and manage tests (including unit, functional, integration, performance, usability, and more). Foundation models need to consider combinatorial spaces spanning millions of choices. Lexical approaches can whittle these down to a thousand. This enables them to fit the context window of foundation models, which can then synthesize the optimal answer. Foundation models support Sapient’s mission of faster, more reliable software testing for everyone in three principal ways:
- Helping to generate precise test code of uncompromising quality.
- Automatically tying tests together across the stack, especially when the linkages are not obvious.
- Providing visibility into the health of tests across an enterprise, intelligently suggesting test updates based on changes in dependencies or performance, and modeling those updates for easy commits.
Historically, we have seen a number of attempts to build new testing platforms, but in addition to their limited utility and accuracy, they couldn’t deliver a strong user experience for all the different personae involved in software testing. Sapient’s platform, by contrast, addresses testing requirements across the entire stack: from frontend application developers, to backend services and data systems developers, to operational developers and SREs. Addressing each of these functions in a single platform is staggeringly difficult, yet it is an essential step toward maximizing one of the greatest virtues of foundation models: their ability to transfer learning between domains. For example, the model you train for frontend tests might be applicable to backend-services tests (and more). Sapient not only eliminates the manual test coding and guesswork that typically plague individual developers, but also maximizes the cross-stack utility of each test generated.
Rishi Singh, Sapient’s founder and CEO, previously co-founded Harness, the pioneering DevOps platform company. As CTO, he spent seven years solving the myriad challenges of continuous delivery, including the urgent need for accurate testing, through the thoughtful application of machine learning. Prior to Harness, Rishi led the development of Apple’s deployment automation platform, immersing himself in the universal problem of how to deliver rapid and significant changes without introducing new points of failure. His unique perspective, coupled with his ability to build core infrastructure, makes him the ideal leader to fulfill the promise of a next-generation, AI-powered software testing platform - and he has assembled a uniquely formidable team.
We believe that the future of AI-driven developer tooling lies in specialized, highly contextual platforms such as Sapient. By focusing on discrete stages of the development process, i.e. testing, feature creation, or refactoring, these AI developer tools will empower developers to write elegant code with unprecedented efficiency - doing what they do best while balancing all of the responsibilities their roles have come to embody.
Today, Sapient emerged from stealth, backed by $5 million in seed funding led by 8VC. We are honored to partner with Rishi and friends as they set sail to reshape the landscape of AI-powered developer testing - and software development as a whole.
Closer than They Appear: Spartan Radar & The Future of Automotive Safety
Spartan Radar’s momentum continues to build following their Series B (led by 8VC and joined by strategics Microsoft and Wipro), with rapidly expanding partnerships and the addition of radar engineering authority Dr. Matt Markel as President.

8VC Emerging Builders Spotlight: Piyush Jain (Yugabyte)
Today we are highlighting Piyush Jain from Yugabyte. Piyush is a software engineer at Yugabyte working in the database group. Before this, he worked at Nutanix, after which he completed his Masters at UT Austin with a focus on distributed systems. In his free time: Piyush keeps an eye on developments in layer 1 blockchains, enjoys hiking, practicing yoga and playing tennis (started picking up recently).
8VC Emerging Builders Spotlight: Ross Carter (Epirus)
Today we are highlighting Ross Carter from Epirus. Ross Carter is a Senior Software Engineer and the Product Software Scrum Master at Epirus, with a specialization in embedded software development. He graduated from the California Institute of Technology in 2020 with a bachelor’s degree in Physics & Computer Science and joined Epirus immediately afterward. Outside of work, he enjoys making pottery, going to (mostly country/blues) concerts, and anything outdoors/active.

8VC Emerging Builders Spotlight: Scott Marin (Epirus)
Today we are highlighting Scott Martin from Epirus. Scott hails from Colorado where he had internships working on mmWave radar spatial mapping for the DARPA Subterranean Challenge, a Tier-II drone radar, and an in-flight internet module and studied under the esteemed Dr. Zoya Popovic at the University of Colorado - Boulder. He came to Epirus after deciding to defer pursuing a Masters degree due to the drop in education quality at the start of the covid pandemic. Since coming to Epirus, his growth as an RF engineer accelerated working on cutting-edge products with mentorship from the phenomenal Epirus team. In his free time, Scott enjoys climbing and backpacking.
