At Jellyfish.tech, we bridge the gap between "it works as a demo" and "it's production-ready." In an era of instant AI prototypes, the real challenge isn't building fast—it's building right. We specialize in taking complex visions and turning them into stable, scalable, and secure digital products. Whether we are architecting an AI agent from scratch or rescuing a legacy system that has hit a technical ceiling, we focus on engineering integrity that supports business growth.
What we do best:
- AI-Driven Development & R&D. Beyond the hype. We build intelligent systems (LLMs, Agentic AI, Vector search) with deterministic logic and predictable costs.
- Software Modernization (The "Rescue Mission"). We take over legacy or fragmented AI-generated codebases, refactor the architecture, and make them scalable.
- MVP to Scale. We use AI to prototype in days, but apply senior human judgment to ensure the foundation can handle the first 10,000 users.
The Jellyfish.tech Advantage:
- We cut time-to-market by 30% using AI-driven prototyping (Vercel v0, etc.), allowing you to test hypotheses before committing to heavy development.
- We don't just "prompt" code. Our senior engineers define the architecture first, ensuring that AI-assisted contributions are secure, tested, and maintainable.
- Founded by product leaders, we speak the language of ROI and business logic, not just syntax and frameworks.
- We choose quality over quantity. You get direct access to senior expertise, transparency, and a team that takes full ownership of the outcome.
Core Industry Expertise:
- AdTech & Marketing Automation (Google Ad Grants tools, keyword intelligence, ROI tracking)
- AI Intelligence (Meeting automation, Agentic workflows, R&D)
