Tersum

Tersum is a boutique AI-native product studio based in Bengaluru, India, building AI systems, full-stack web products, and growth infrastructure for startups and growing businesses.

We work across three areas. The first is AI and automation: LLM-powered features, RAG systems, AI agents, natural-language interfaces to data, and workflow automation that removes manual work. The second is full-stack development: web apps, client portals, dashboards, and SaaS products, taken from scope to production. The third is growth: SEO and GEO (generative engine optimization), so your product is found both in search and in AI answers.

What makes us different is how we work. Every engagement starts with scope discipline. Before anything gets built, we agree on what's in, what's out, and a written "no" list, so budgets and timelines hold. You work directly with the engineer building your product, with no account managers and no sales layer in between. Because we don't carry an overhead bench, our rates sit 20–30% below typical agency pricing. That's a structural advantage, not a discount.

Whether you need a quick proof of concept to validate an idea, an MVP to get your product in front of users, or a white-label build your agency can deliver under its own brand, we're ready to build it.

We work with clients in the US, UK, Europe, the Middle East, and APAC, and offer fixed-price milestones and pilot projects so you can start small and scale once you've seen results.
