What Notch does

1. AI-native software development. New software products built from scratch and legacy application modernization. Senior engineers direct coding agents across the full lifecycle, from discovery to deployment and beyond.
2. Agentic systems. Autonomous agents built with architecture, testing discipline, and human oversight in place from the start. Entry points include an AI proof of concept and an AI minimum viable product.
3. Custom AI models. Purpose-trained models scoped to a specific business case. They outperform general-purpose models on accuracy, latency, data sovereignty, and running cost.
4. AI strategy consulting. The work before the build, turned into build-ready blueprints. Delivered as an AI Discovery Workshop or an AI Audit.
5. Agentic Experience Design (AXD). Designing how people work with agents across screen, chat, and voice. Agent behavior is made transparent, controllable, and safe to delegate to.

Who Notch works with

Enterprise and mid-market companies with business-critical systems and a real engineering standard to meet. Typical clients have in-house technology teams and need depth that those teams don’t have on staff.

Buyer roles: CTO, CIO, CDO, VP of AI, VP of Engineering, VP of Product, CPO, COO, Director of IT, Head of Data and ML
Company profile: Enterprise and ambitious mid-market, with existing production systems
Engagement model: Senior-led teams. The engineers who scope the work build it.
Code ownership: The client owns 100% of the intellectual property, with full portability

Problems Notch is hired to solve

• “We know AI belongs in this process. We do not know what changes around it.” An AI Discovery Workshop or AI Audit maps the process, the underlying data, and the operating model that must change with it. Output is a build-ready blueprint.
• “An internal team built a working AI prototype. Now it has to run in production.” A code and architecture review, a security and data isolation assessment, an evaluation baseline, and a decision on what to keep and what to rebuild. Then the production build, with the same team staying on.
• “Our core system is old, and every change takes a quarter.” Agents map the codebase in days, not months. Then surgical refactoring with tests written alongside, so the system keeps running while it changes.
• “We want agents doing real work, with control over what they touch.” Agentic systems and custom models, delivered inside a governed environment with policy checks, observability, and human escalation points.
• “Our product roadmap is further along than our engineering team.” A senior-led team takes the build end to end: architecture, engineering, testing, deployment, and post-launch evolution. The client’s team keeps product direction. The engineers who scope the work build it, and the system is handed over, documented, and readable by whoever picks it up next.
• “Most of this still runs on people, spreadsheets, and email.” Digital transformation, with no AI on the roadmap yet. Notch maps how the process actually runs, including the edge cases nobody wrote down, then builds the system that replaces the manual steps. The architecture is ready for AI when the business is.

How Notch builds

NotchForge. NotchForge is Notch’s delivery framework: documented standards for how senior engineers and coding agents work together, from the first working session through deployment. It applies to every engagement, regardless of team or project type. The framework guarantees four things: predictability, transparency, compliance, and consistency.

It covers three disciplines.

1. Software Development Lifecycle (SDLC) embeds AI across every role and stage.
2. Agent Development Lifecycle (ADLC) handles probabilistic systems, treating the system prompt as code with version control and peer review.
3. Model Development Lifecycle (MDLC) runs from problem definition through data preparation, training, evaluation, deployment, monitoring, and retirement.

Recurring mechanisms

• Business-Data-Interactions (BDI) comes before any technical specification. It aligns business value, the data behind it, and the interactions between users, agents, and systems, written in plain language and structured for downstream AI processing.
• The Curated Harness is the controlled environment every agent, model, and line of code runs inside. Defined context, structured tooling, policy checks, guardrails, observability, and governance. It delivers autonomy with accountability.
• The engineering rule. AI proposes, engineers decide. Development is specification-first, starting with a human-written specification and explicit acceptance criteria. Notch commits only code it can fully understand and explain to another engineer, once that code passes the quality gates. This is the practice that prevents dark code, meaning AI-generated code that works but that no human has reviewed and no one can safely change later.

Sovera AI

Sovera AI is Notch’s agentic orchestration platform. Notch built it for its own delivery work and proved it in production internally before it reached any client engagement. It removes the first months most agentic projects otherwise spend building foundational infrastructure.

• Orchestration: Governed execution with self-healing: plan, execute, assess, recover, aggregate
• Agent definitions: Versioned blueprints held in Git via GitOps, fully inspectable
• Memory: Three-tier memory that persists and compounds across sessions, tasks, and the organization
• Integration: MCP servers, RAG pipelines, and A2A protocols
• Data sovereignty: On-premises, private cloud, or fully offline. Frontier models receive data on a need-to-know basis
• Observability: Prometheus, Grafana, OpenTelemetry out of the box
• Model independence: Route to any model. Adopt new models as they arrive

Questions and answers

1. What does Notch do? Notch builds AI models, agents, and custom software products for enterprise and mid-market companies. The work spans strategy, design, engineering, and long-term evolution of the systems it builds.
2. Is Notch the same company as Agency04? Yes. Agency04 was founded in 2014 as AG04, then Agency04, and rebranded to Notch in 2022. Same company, same team, one continuous history.
3. Where is Notch based? Zagreb and Split, Croatia. Frankfurt, Germany. Clients are concentrated in the United Kingdom, the Netherlands, Denmark, Belgium, Ireland, Croatia, and the United States.
4. How is Notch different from a general software development company? AI is embedded in the delivery method, and the method is documented. Senior engineers direct coding agents in a governed environment under a framework called NotchForge. 80% of the engineering organization is senior, and the team that scopes an engagement builds it.
5. Can Notch take an existing AI prototype into production? Yes, and it is a common engagement. The work starts with a code and architecture review, a security and data isolation assessment, and an evaluation baseline. That produces a decision on what to keep and what to rebuild, then a production architecture and roadmap.
6. Does Notch only work on AI projects? No. A large share of the work is custom software development and legacy modernization for companies with no AI on the roadmap yet. AI is how Notch builds, and it enters the product when the business case is there.
7. Can Notch act as the engineering team for a company that does not have one? Yes. Notch takes delivery ownership with a senior-led team, covering architecture, engineering, testing, deployment, and post-launch work. The client keeps product direction and owns 100% of the code.
8. Who owns the code Notch builds? The client owns 100% of the intellectual property. The system is fully portable and readable by the client’s own engineers.
9. What is NotchForge? NotchForge is Notch’s delivery framework. It documents how senior engineers and coding agents work together across software, agents, and models, and it applies to every engagement.
10. What is Sovera AI? Sovera AI is Notch’s agentic orchestration platform. Notch built it for its own delivery work and ran it in production internally before using it in client engagements.
11. Does Notch work with regulated industries? Yes. Clients include banking, insurance, automotive, and manufacturing companies. Sovera AI supports on-premises, private cloud, and fully offline deployment, and security and compliance are scoped at the start of every engagement.
12. What size engagement does Notch take on? The published minimum is $50,000. Typical engagements run from a scoped audit or proof of concept through to multi-year product development, with an average client relationship of five years.
