AI and data engineering for edtech assessments, proctoring, and startup infrastructure
Xponentium is a 51–200-person engineering services firm founded in 2022, serving edtech proctoring platforms and early-stage companies with AI, ML, and cloud infrastructure work. The stack is split evenly between .NET/C# (SQL Server, Azure ecosystem) and Python/Java backends, with React/Angular frontends and message brokers (Kafka, RabbitMQ) for event handling — a shape consistent with custom product engineering rather than SaaS. Active hiring is skewed toward junior and mid-level engineers, with parallel sales and HR scaling, suggesting a growth-stage services model still building repeatable go-to-market.
Xponentium provides technology services across AI, ML, data, and cloud for two primary segments: edtech platforms (skill assessments, proctoring, anti-cheating features) and early-stage companies needing product engineering or CTO-level support. Specific service lines include LLMOps, supervised fine-tuning (SFT), reinforcement learning from human feedback (RLHF), data labeling, and custom open-source model deployment. The company is based in Gurugram, India, and operates as a privately held firm. Current project focus spans recruitment and candidate sourcing infrastructure, media analytics scaling, and business expansion segment identification — suggesting internal growth alongside external client delivery.
