SiftDev builds an intelligent logging platform that transforms complex observability data into actionable insights for engineering teams. The core product provides real-time anomaly detection and enables natural language interaction with logs, moving beyond traditional manual search. By applying semantic analysis and comprehensive behavioral profiling, the platform distinguishes normal application patterns from true deviations, offering clear explanations and context for identified issues.
The company was founded by Kaushik and Ishir, both former product and engineering leaders at Datadog and Splunk. Their insight stemmed from observing pervasive struggles among development teams to effectively utilize vast quantities of logging data, even with leading tools. They recognized a significant gap between machine-generated data volume and human capacity to extract meaningful intelligence, leading them to create a solution that automates the tedious aspects of debugging.
SiftDev targets developers and engineers contending with complex debugging and observability challenges. The company's vision centers on bridging the machine-to-human data gap, aiming to eliminate the need for manual log inspection. Ultimately, SiftDev seeks to empower technical users to interact with their data intuitively, ensuring they receive precise, actionable answers that streamline operations and enhance system reliability.

Sift (also known as Sift Stack or Sift Dev) is a technology company building an observability platform for real-time telemetry data from complex hardware systems, such as spacecraft and autonomous vehicles.[1][2][7] It serves hard tech companies like Astranis, Astrolab, Mach Industries, Parallel Systems, K2 Space, Impulse, and JetZero, solving the problem of processing vast machine data to enable automated anomaly detection, data visualization, and accelerated development cycles without manual testing burdens.[1][2][7] The platform unifies data ingestion, storage, analysis, and insights, saving customers thousands of engineering hours and over $100k in costs by replacing fragmented or in-house tools.[7]
Founded in 2022 in El Segundo, CA, Sift has shown strong growth momentum, raising a $17.5M Series A led by GV in 2023 after a seed from Riot Ventures and Fika Ventures, and launching as YC W25 with an AI-powered alternative to tools like Datadog focused on semantic log analysis.[1][4]
Sift was founded in 2022 by CEO Karthik Gollapudi and Austin Spiegel, drawing inspiration from experiences at SpaceX where outdated tools hindered development of complex machines like reusable rockets and autonomous systems.[1] The idea emerged from recognizing a gap in observability for real-time data from sensors in hardware-intensive industries, where engineers face torrents of telemetry but lack modern tools for actionable insights.[1][2] Early traction came quickly, with high-profile customers adopting the platform to automate data review and cut development time, leading to rapid funding and expansion.[1][7]
Sift rides the hard tech resurgence, where rockets, autonomous vehicles, and advanced manufacturing generate massive real-time data that legacy software observability tools can't handle efficiently.[1][2] Timing is ideal amid booming space (e.g., Astranis) and autonomy sectors, fueled by falling launch costs and AI advancements enabling complex machines.[1][7] Market forces like regulatory demands and development speed pressures favor Sift, as companies avoid diverting engineers to custom telemetry fixes.[7] It influences the ecosystem by standardizing observability for hardware, supercharging reliability across industries and reducing "catastrophes" in high-stakes deployments.[1]
Sift is poised to dominate hardware observability as AI profiles evolve to predict failures preemptively and expand beyond telemetry into full-stack machine intelligence. Trends like edge AI proliferation and multi-modal data (sensors + manufacturing) will amplify demand, potentially scaling Sift into a Datadog for hard tech. Its influence could reshape sectors by making "mind-bending complexity" routine, evolving from accelerator to indispensable backbone for the next wave of physical-world innovation—building on its SpaceX-honed vision to transform real-time data mastery.[1][4]
