AI Agent Development FAQs

The important thing is to
never stop questioning

What are AI agent development services?

AI agent development services focus on designing, building, and maintaining custom AI agents that can autonomously perform tasks such as data processing, decision-making, integrations, and workflow automation using large language models (LLMs). Unlike basic chatbots, AI agents can reason, call tools, interact with APIs, and execute multi-step workflows in production environments.

What are AI workflows?

AI workflows are structured processes where artificial intelligence is used to automate tasks, decisions, and data processing across systems. They combine AI models (such as LLMs) with business logic, APIs, and databases to execute multi-step operations automatically.

What is the difference between AI workflows and AI agents?

AI workflows are structured, predefined processes.

AI agents are more autonomous and can decide which actions to take dynamically.

In practice, many systems combine both:

  • Workflows for structure

  • Agents for decision-making

What is the difference between an AI agent and a chatbot?

A chatbot primarily responds to user input in a conversational way. An AI agent, on the other hand, can:

  • Make decisions

  • Execute actions

  • Call external APIs and tools

  • Maintain state and memory

  • Operate autonomously without constant user input

    AI agents are designed for real business processes, not just conversations.

What is AI workflow automation?

AI workflow automation refers to using AI to replace or enhance manual business processes, such as:

  • Data entry and enrichment

  • Document processing

  • Customer support handling

  • Internal reporting and analysis

Unlike traditional automation, AI workflows can handle unstructured data and make context-aware decisions.

What are AI agents for business automation?

AI Agents for business automations can serve multiple purposes:

  • Internal process automation

  • Customer support workflows

  • Data analysis and reporting

  • CRM and CMS automation

  • Lead qualification and enrichment

  • AI-powered internal tools

  • Content operations and knowledge retrieval (RAG systems)

The best use cases are processes where people currently spend time gathering information, making routine decisions, or moving work between systems. In those cases, custom AI agents can reduce manual effort while keeping humans in control of exceptions and approvals.

How do AI workflows differ from traditional automation?

Traditional automation relies on fixed rules and predefined logic.

AI workflows can:

  • Interpret natural language

  • Handle incomplete or messy data

  • Adapt to different inputs

  • Make probabilistic decisions

This makes them far more flexible for real-world business scenarios.

Do you build AI agents using OpenAI, Claude, or open-source models?

Yes. We build AI agents using OpenAI models, Anthropic Claude, and open-source LLMs, depending on your requirements around cost, performance, data privacy, and hosting. We help you choose the right model and architecture rather than locking you into a single vendor.

Do you provide AI agent integration services for existing web applications?

Yes. A big part of our work is AI agent integration services for existing web applications, internal tools, and backend workflows. We can connect AI agents to your current product, APIs, databases, auth systems, and third-party platforms without forcing a rebuild.

This often includes embedding agents into SaaS platforms, admin panels, customer support flows, or operations tooling. We also build AI workflow agents that can trigger actions, retrieve context, and coordinate multi-step processes inside your existing stack.

What are examples of AI workflows in businesses?

Common AI workflow examples include:

  • Automatically classifying and routing support tickets

  • Extracting data from PDFs and invoices

  • Generating and reviewing content

  • Enriching CRM data with external sources

  • Summarizing internal knowledge and documents

  • Processing cancellations, refunds, or requests

These workflows often span multiple systems.

What industries benefit most from AI agent development?

AI agent development is industry-agnostic but particularly effective for:

  • SaaS and B2B platforms

  • E-commerce and marketplaces

  • Media and publishing

  • Professional services

  • Fintech and legal tech

  • Operations-heavy businesses

Anywhere repetitive decision-making or data-heavy workflows exist, AI agents add value.

How is AI agent development different from AI automation tools like Zapier or n8n?

No-code tools are great for simple workflows. Custom AI agents go further by:

  • Handling complex logic and branching

  • Reasoning over unstructured data

  • Maintaining long-term memory

  • Operating securely inside your infrastructure

  • Scaling with your product

AI agent development is ideal when off-the-shelf automation tools hit their limits.

Are AI agents secure and GDPR-compliant?

Yes, when built correctly. We design AI agents with:

  • Secure API handling

  • Controlled data access

  • Explicit permission boundaries

  • GDPR-aware data flows

  • Optional EU-based hosting

Compliance and security are architectural decisions — not afterthoughts.

Can AI agents work with private company data?

Yes. AI agents can securely access private data via:

  • Retrieval-Augmented Generation (RAG)

  • Vector databases

  • Role-based access control

  • Scoped API permissions

Your data is never used to train public models unless explicitly configured.

What tools are used to build AI workflows?

AI workflows can be built using:

  • LLM APIs (OpenAI, Claude, open-source models)

  • Workflow engines (e.g. n8n, custom orchestration)

  • Backend services (Node.js, serverless functions)

  • Vector databases for retrieval (RAG systems)

  • API integrations with third-party systems

We typically combine off-the-shelf tools with custom code for flexibility.

How long does it take to build a custom AI agent?

A simple AI agent prototype can be built in 1 week.

Simple use cases can move fast, but most teams that want to build custom AI agents in production should expect a phased rollout. A production-ready setup often takes 2-6 weeks, depending on the number of integrations, workflow complexity, guardrails, and testing requirements.

For custom AI agent development, we usually start with one high-value workflow, ship it, measure how it performs, and then expand the agent’s scope over time. That reduces risk and gets useful automation live sooner.

Can AI agents be maintained and improved over time?

Yes — and they should be. AI agents benefit from:

  • Ongoing prompt optimization

  • Model upgrades

  • Monitoring and logging

  • Performance tuning

  • New integrations as your business evolves

We treat AI agents as long-term software systems, not one-off experiments.

When should you use custom AI workflows instead of no-code tools?

No-code tools are suitable for simple use cases. Custom AI workflows are better when:

  • Logic becomes complex

  • You need reliability and error handling

  • Security and compliance matter

  • Workflows are core to your product

  • Performance and scalability are critical

That’s where engineering becomes necessary.

Do AI agents replace human employees?

AI agents are designed to augment teams, not replace them. They handle repetitive, time-consuming tasks so humans can focus on higher-value work such as strategy, creativity, and decision-making.

What tech stack do your custom AI agent developers use?

Our custom AI agent developers usually work with TypeScript and JavaScript-based product stacks, alongside the orchestration, retrieval, observability, and infrastructure tools needed for reliable AI systems. We build with the model layer that best fits the problem, including OpenAI, Anthropic, and strong open-source options when appropriate.

If you are looking for an LLM agent development company, the important thing is not loyalty to one model vendor. It is the ability to design the full system around your workflows, integrations, data boundaries, evaluation needs, and long-term maintainability.

What is RAG in AI workflows?

RAG (Retrieval-Augmented Generation) is a technique where AI workflows:

  1. Retrieve relevant data from a database or knowledge base

  2. Provide that data to an LLM

  3. Generate accurate, context-aware outputs

This allows AI workflows to work with private and up-to-date information.

How much do AI agent development services cost?

Costs depend on:

  • Agent complexity

  • Number of integrations

  • Hosting and model usage

  • Security and compliance needs

Most projects start with a discovery phase followed by an MVP and iterative rollout. We provide transparent estimates based on real scope — not vague AI promises.

Is AI agent development suitable for small and mid-sized companies?

The best starting point is identifying one concrete workflow or problem that:

  • Is repetitive

  • Uses structured or semi-structured data

  • Requires decision-making or reasoning

From there, we define the agent’s responsibilities, integrations, and success metrics.

How do we get started with AI agent development?

The best starting point is identifying one concrete workflow or problem that:

  • Is repetitive

  • Uses structured or semi-structured data

  • Requires decision-making or reasoning

From there, we define the agent’s responsibilities, integrations, and success metrics.

I want to keep my idea confidential. Will you sign an NDA with me?

Yes, we sign an NDA (Non-Disclosure Agreement) always when a client wants it. We can do it at the very beginning before we discuss your project's details, or at another stage of the process - it's up to you.

Do I own the intellectual property rights of my application?

Yes, you are the owner of Intellectual Property rights at all times.

Where is your development team located?

We are fully remote. So while we were founded and are still based in Berlin, most developers will be remote from a central European location.

What is the pricing model?

You work with us on a Time & Materials basis. The total cost depends on the actual time the team spends on the development. You are in charge of the project’s scope and set priorities for the development team.

Time & Materials allows flexibility for you to set the direction of development depending on the users’ feedback, market situation, or opportunities that arise during the development.

For more about how we create estimates read how to estimate software projects .

What would my development team look like?

We adjust the team depending on your needs. Our speciality is low overhead teams, where every member is contributing concretely towards customer facing features. That means everyone is either doing development or design.

Roles like Project Manager, Business Analyst and QA are responsibilities which are shouldered by our business oriented developers or designers.

You may take the role of a Product Owner, making decisions on priority and scope.

Can you work as an amendment to our in-house team?

Yes. We can adapt to your tools and processes. I.e. fully integrate into your existing team.

How does the company ensure code quality and maintainability?

We follow best practices, perform code reviews, implement automated testing and continuous integration to ensure code quality and maintainability. All projects are not equal though and the level of automated QA will be determined on your need for quick feedback from the market.

Can you hand the code over to another team?

Yes. We create easily understandable and maintainable code using well known frameworks which don’t require niche knowledge.

The runtime environments we can set up in your ownership from the get-go.

What is the experience level of my team?

Every team has a partner involved in the project. Our developers have a proven track record of outsized throughput. Our culture is one of delivering features every day. That's why we prefer senior developers, but not seniors that are from slow moving enterprise environments.

How am I kept up-to-date of development?

We have fixed length iterations (usually 1 week), at the end of which you will be demoed the current progress. You will have access to team members through Slack, email and video calls and our regular meetings. In addition to this you will have access to our project management tools (Jira or Asana), which we update daily.

Why hire us?

We love what we do and only employ people with a similar mindset. You ship faster by working with a small team where each developer is a focused on your business goals. With us you get direct access to everyone. This keeps overhead low and output high.

You are in control. We offer full transparency of progress and potential problems. We keep you informed and present options, but you make the decisions.

We value our client relationships and their product visions. Meet with us to see if we share the same conviction. We might be a good fit.
