CTO, lucaCustom software and AI workflows,
shipped in weeks.
webvise designs, builds, and automates the internal tools, portals, dashboards, and agentic workflows your business actually runs on. You work directly with the engineer who ships it.
The workflow already exists. It is just scattered across spreadsheets, inboxes, admin screens, and AI experiments that no one can operate safely.

Engineer-led delivery. No agency overhead.
Traditional agencies split strategy, design, development, and delivery across multiple people. The loop stays tight here: you work directly with Sebastian, the engineer responsible for understanding the workflow, designing the system, building the application, and shipping it to production.
AI-native development shortens the timeline, while product and architecture decisions stay in experienced hands.

Client feedback
Real feedback from people who worked directly with Sebastian.
The work was so straightforward and clear. Sebastian understood my idea from the start and implemented it very well.
Anna-Maria von Platen
Founder, vonplaten-coachingSebastian built my MVP within a week and guided me step-by-step on how to grow and scale it afterwards. His mentorship gave me the tools to independently expand the project.
Lennart Brauer
Founder, CascadySebastian built and continues to manage our website, providing reliable support for several years. His consistent quality and dependability have been essential for our online presence.
Sebastian Kundoch
Engineer, MP BauSebastian built me something I haven't seen on the market. A research studio that thinks in my voice, scans broadcaster feeds while I sleep, and renders the final DOCX in our publisher CI without me touching a single template. The vault is where my work actually lives now. I pitch more, sharper, faster.
Felix Rautenberg
Documentary Producer, doclightsWe have worked with Sebastian and webvise for several years on different projects, especially website and web app creation. Sebastian is not only very quick and 100% committed, but also always thinking ahead, taking future developments into account, and creating perfectly customized solutions. We highly recommend working with webvise!
Joshua Kunisch
Vice President, young leaderswebvise delivered a production-ready platform that exceeded our expectations. The automated certificate flow and the conversion-optimized funnel have become core to how we operate. Reliable, fast, and always thinking ahead.

AI Agents / Service Operations
Relay: A Delivery Engine Concept for AI-Native Service Companies
A design-led MVP concept for service companies that sell finished outcomes through governed workflows. Relay scopes the result, lets agents run the workflow, routes work through human review gates, ships the deliverable, and shows the margin on every run.
AI Agents / Agent Infrastructure
Keel: An Agent-Native Infrastructure Concept for SaaS Products
A design-led MVP concept for making any SaaS product usable by AI agents. Keel introspects a product's API, UI, and docs, turns every operation into a typed, named tool with a hosted MCP server, and exposes one governed endpoint behind scopes, guardrails, and approval gates. Every call is scoped, traced, and replayable.
AI Agents / Company Memory
Morrow: A Company-Memory Concept for AI-Native Teams
A design-led MVP concept for giving AI agents company memory they can trust. Morrow pulls Slack, Linear, GitHub, Notion, calls, and tickets into one reviewed context layer, turns it into executable skill files, and serves it to agents through an API. Every answer carries the evidence it came from.

Delivery process
Five delivery stages turn the plan into a launched product with visible progress, review points, and production checks.
01
Discovery
Discovery clarifies the vision, audience, goals, success criteria, and project shape.
02
Planning
A tailored roadmap with milestones, technology recommendations, and a clear timeline for delivery.
03
Execution
Weekly demos, rapid iterations, and daily deployments. You see progress every step of the way.
04
Optimization
Performance, accessibility, conversion, build quality, and launch checks stay visible through testing and refinement.
05
Launch and Support
Deployment moves to the agreed target with documentation, monitoring where needed, and the support window defined before launch.
Three paths. One keeps ownership direct.
Traditional agencies add layers. Task-only vendors narrow the work. Responsibility stays in one place here, with AI-native delivery.

Launch is not the end.
Business software becomes valuable when people actually use it. After launch, monitoring, fixes, small improvements, workflow extensions, and AI automation support keep the system close to the team that runs it.
Plan ongoing supportMonitoring and fixes
Keep the application observable, stable, and ready for the real usage patterns that appear after launch.
Small improvements
Ship practical iterations without restarting the whole project or adding an agency layer.
Workflow extensions
Add new integrations, roles, AI steps, and admin workflows as the system becomes part of daily operations.

How Long Does It Take to Build an MVP? A Practical 3 to 5 Week Plan
A focused MVP takes 3 to 5 weeks when it tests one workflow with standard auth, one data model, and one success metric. Here is the honest timeline and what stretches it.
Common Questions
Everything you need to know before getting started.
It depends on the workflow and system shape. Landing pages usually take 1-2 weeks. Full-stack apps or migrations usually take 3-6 weeks. A detailed timeline follows after the initial consultation.
The build plan defines the workflow, users, integrations, data model, AI requirements, timeline, deliverables, and support expectations before implementation starts.
Projects are estimated individually because effort depends on the workflow, users, integrations, data model, AI requirements, and support level needed after launch. Launch, Operate, and Automate work each get a clear plan before implementation starts.
Yes, 100%. You get the full source code, repository access, and deployment setup. It's yours to maintain, extend, or hand off to another team.
Core stack: Next.js, React, TypeScript, Tailwind CSS, and PostgreSQL. AI tooling: Vercel AI SDK, OpenAI, and Anthropic. Deployment runs on Vercel with monitoring via Sentry and PostHog.
You work directly with Sebastian Kehle, the engineer responsible for understanding the workflow, designing the system, building the application, and shipping it to production.
MVP Development covers this: feature scoping, UI design, and a working product in 3-5 weeks, ready for real users and investor demos.
Yes. After launch, monitoring, fixes, small improvements, workflow extensions, and AI automation support are all available. The support cadence is planned around the system and your team.
