Jotsu

Model and Agent Optimization Services

Optimize Models, Elevate Agents

Jotsu’s Model and Agent Optimization services tune your LLMs and agentic workflows for measurable gains in accuracy, latency, cost, and reliability.

The Jotsu Difference

Platform + experts: From strategy to shipped fast—prototypes in days, production in weeks.

Model Strategy

We focus on building genuine partnerships — your success is our top priority.

Prompts, Tools, and MCP

Refine prompts, improve tool schemas and function-calling, harden MCP servers (timeouts, retries, error handling).

RAG and Memory

Optimize embeddings, chunking, hybrid search, rerankers, caching, and context/memory policies.

No Vendor Lock-In

Our solutions are standards-driven, cloud-agnostic, and you fully own the codebase — ensuring you get a solution you can use.

Low-Risk Engagement

We work with a fixed-price model backed by clear milestones and a transparent development process to eliminate uncertainty.

US-Based Team You Can Trust

Jotsu is a US-based company with an experienced management team. Reach out — we’re here to help.

Our Development Process

Built around your goals, managed end-to-end—milestones you can see, quality you can trust, support you can count on.

Discovery and scoping

Baseline current models/agents with telemetry; map prompts, tools/MCP servers, RAG/memory, data sources, and constraints; define acceptance criteria that will be used to benchmark and improve AI models and agents.

Architecture and design

Craft an optimization plan—model strategy, prompt strategy, RAG improvements, tool/MCP hardening, caching, and guardrails.

Prototype and validation

Run focused experiments and A/B tests on golden tasks; validate impact on accuracy, latency, and spend; iterate quickly on prompts, retrieval, and tool design.

Implementation

Incrementally roll out changes—prompt refactors, model config/tuning, retrieval pipeline updates, MCP/tool fixes, caching and batching; document semantics and rollback plans.

Testing

Execute offline/online evals, regression suites, and performance/load tests.

DevOps and deployment

Secure, compliant, observable, and built to scale. Ongoing maintenance included.

What Our Customers Say

Owner, Basecamp

Jotsu built an AI agent that triages, qualifies, and engages every website lead in real time, syncing to our CRM and booking meetings for reps automatically.

Director & Co-Founder, VFXR.io

Exceptional technical insight and a rare ability to turn experimental ideas into working AI systems. Their contribution in connecting our framework architecture with a scalable backend — and integrating the Jotsu playground and workflows — made a real difference. Multimodality is clearly the way forward, and this team truly bridges technology and creativity.

Co-founder, Haytruck Digital

The custom MCP server Jotsu developed gave us a clean, secure, vendor‑neutral interface to our APIs, replacing brittle scripts with a single, well-documented layer.
