AI powered ERP for Construction

Merlin is an AI-powered ERP for construction companies. We provide construction companies with a single, AI-powered platform to manage their entire business operations. Our platform unifies project management, materials management, finance, estimating, and CRM—traditionally scattered across multiple systems—into one cohesive solution. For the first time, construction firms can automate and oversee every aspect of their projects in a single, intuitive system. Today, construction companies pay for 8-17 different tools - that we eliminate the need for. We reduce - Manual work by 60% - Cut software costs by $10,000 monthly - Complete projects 3x faster. Why Now? We're witnessing a perfect storm of factors: decades of stagnation in traditional ERP systems, a multi-billion-dollar industry built on misaligned incentives, and the transformative potential of AI. This confluence creates a rare cyclical opportunity for market upheaval. The last major shift in this space occurred in the 1990s with the advent of digital systems, and now, 30 years later, we're on the cusp of another seismic change. Customers are crying out for innovation and as AI reshapes the landscape, early customer signals indicate an eagerness for smarter, more efficient systems. It's a unique window of opportunity that opens perhaps once in a multi-decade chance to redefine an entire industry's operational backbone. Team: KS, a BITS Pilani grad and successful startup co-founder, and Ayantika, an IIT alumni and tech expert, bring extensive coding and product development expertise together bringing about over a decade of technical expertise. Sneha ( that’s me), with over a decade of experience in supply chain management and lean manufacturing within the construction industry, has lived the pain of using ERPs in this industry.

The operating system for the 100x Engineering Team

Mesmer is the operating system for agentic engineering teams. A few engineering teams are accelerating at breakneck speed, while most are stuck with incremental gains. Mesmer exists so that gap doesn't come down to who gets lucky with their AI experiments. We help founders and CTOs turn agents into real leverage across their organization: faster delivery, better quality, less bureaucracy, and a clear view of where the bottlenecks are and what to do next. Hundreds of engineering teams have used Mesmer to >2x their productivity in the first quarter using our platform. We are a team of repeat founders and CTOs with 15+ years of experience, including leading engineering together at Origin Financial ($400M), the AI financial advisor founded by Mesmer's CEO.
