Best practices for building secure business applications with AI

Building an app with AI can help product teams move faster, but speed alone does not create something people will use. The best AI-built applications solve a real problem, fit how people actually work, and meet the governance and security standards your organization expects.

Aha! Builder brings planning, building, and operating into one place so teams can create usable applications with clear guardrails and less risk. This article provides a practical approach, from choosing the right problem to deploying and improving the application over time.

Identify the right problem

Every application carries ongoing responsibility: maintenance, support, and cost. Start with a clear process for managing AI application development — deciding what to build and ensuring the right people own each project. Establishing a clear approach from the outset ensures that every application supports your priorities and meets your standards.

  • Capture application requests in a central place: Use an ideas portal or a shared intake form to collect requests from across the organization. Each request should describe the problem clearly — who experiences it and what solving it is worth. Centralizing requests prevents duplicate efforts and gives leadership visibility into demand.

  • Evaluate each request against your strategy: Assess whether the proposed application aligns with your business goals and is significant enough to justify ongoing maintenance. Use Aha! Roadmaps to connect application requests to your broader product strategy and prioritize them alongside other work.

  • Confirm the request warrants a new application: Some problems are better solved with a cleaner template, a better report, or an existing tool. Applications make sense when the work involves multiple people and requires ongoing updates with shared visibility.

  • Approve before building: Have leadership and cross-functional reviewers (primarily IT and security) confirm strategic alignment and assess risk. Record the decision so there is a clear audit trail.

Customer request for an onboarding tracker application

Build the first version

Once a request is approved, the next step is describing the problem clearly enough for Elle (the AI assistant) to generate a useful first version. Start with who the application is for and what they need to accomplish.

For this article, we will follow the example of a customer onboarding tracker for Fredwin Cycling, a fictitious SaaS company. Many teams at Fredwin Cycling manage onboarding in email threads, spreadsheets, and chat messages. Everyone is trying to help, but nobody has a single view of milestones, blockers, owners, and status. The goal is to create an application where the team can coordinate work reliably.

  • Define a clear problem description: Describe the workflow and the people involved. The more specific your description, the more relevant the application Elle generates. Here is an example of the prompt you might provide:

"We need a customer onboarding tracker for Fredwin Cycling, our SaaS company. Our onboarding team coordinates each new customer from kickoff to completion, but the work is currently spread across emails, spreadsheets, and chats. We need a shared view of milestones, blockers, owners, and status so nothing falls through the cracks."

  • Choose the right starting format: Decide whether you are building a robust prototype or a business application. A prototype validates the shape of a solution or gathers quick reactions from stakeholders. A business application is meant for ongoing use and deserves earlier thinking about authentication, integrations, and governance. You can convert a prototype to an application later, but begin with the right framing for the problem you are solving.

  • Define success in operational terms: Be specific about what success looks like. For the onboarding tracker, success might mean reducing status meetings or a decrease in missed project due dates. These are better anchors than a loose goal like "make onboarding easier."

  • Define your target personas: Create personas in Plan -> Strategy -> Personas to describe who will use the application — who initiates the work and who keeps it moving. You can define personas before describing the problem to Elle or refine them after seeing the first version. Either way, Elle uses your personas to shape what it generates.

  • Keep the first version focused: Once you have a first version, capture everything that does not belong in the first version as future features in the Features section. The user story map can help you visualize workflow stages and maintain focus. It is much easier to expand a focused application than to simplify one that was overloaded from the beginning.

Design for clarity and consistency

The first version is a starting point. Before iterating on details, get the UX/UI foundation correct.

  • Structure navigation around how people think: Organize the application around the concepts users already understand. In the onboarding example, users think in terms of customers, milestones, blockers, and status. Choose between horizontal and vertical navigation layouts based on the number of primary views and the depth of each workflow.

  • Use the language people already use: Match the terminology in the application to how the team already describes their work. If the team says "blocked," keep that as the status label. Clear language reduces friction faster than almost any visual change.

  • Establish visual consistency early: Choose typography, colors, and layout patterns that make the application easy to scan and easy to learn. If your organization has a strong visual language, link to your design system or provide a reference image to guide Elle.

Full design customization and design systems are available on Aha! Builder Team and Scale plans. Pro plan users can select from six preset color palettes and manually modify styles.

Refine with focused prompts

Refinement is where product judgment matters most, shaping the application so it feels natural to use and earns adoption through clarity rather than complexity.

  • Break refinements into focused prompts: Ask Elle to improve one page, one data relationship, or one workflow step at a time. Each focused prompt gives you a natural review point. Follow the four prompting best practices — add context, segment tasks, be specific, and iterate.

  • Scope changes to specific elements: Use Select elements in the preview to focus Elle on a single component, such as a particular button or modal. Voice input works when a conversational description is easier than typing.

  • Treat every change as reversible: Use code history so experimentation remains safe. When builders trust that they can undo a change, they make better decisions and learn faster.

  • Manage AI credits intentionally: Focused refinements generally consume fewer credits than broad overhauls. You can also enter planning mode with Elle to agree on an implementation direction for major changes rather than letting Elle generate updates and then correcting anything that does not align with your vision. Monitor usage in your account billing settings.

  • Capture ideas you are not ready to build: Add future enhancements to the features board so they are sequenced rather than forgotten. One of the reasons people keep using an application after the novelty wears off is because it does a simple job well.

Configure key capabilities

Set up the access controls and capabilities your application needs. Aha! Builder provides built-in enterprise-grade controls that match the application to its audience and operating environment.

  • Choose the application type that matches your audience: The type determines who can access the application and what data they see:

    • Public: Open access. Anyone with the URL can use the application.

    • Team: Authenticated users share the same data and collaborate in a shared workspace.

    • Private: Authenticated end users see only their own data.

  • Set up authentication: Choose from six methods (Password, Aha!, Google, GitHub, Microsoft, or Custom SSO) and configure them directly. SAML and JWT SSO are available on the Aha! Builder Scale plan.

  • Define roles for your application: Use role-based access control under Operate -> Configuration -> Authentication -> Roles to create roles that match what each person needs to do. Built-in Admin and User roles provide a starting point. Add custom roles — such as Viewer or Manager — to match your workflow. A manager might need only a dashboard and blocker visibility, while an individual contributor needs edit access to milestone data.

  • Configure additional capabilities: Enable the features your application needs under Operate -> Configuration: email notifications (Aha! Builder Scale plan) and integrations with services such as Aha!, Salesforce, HubSpot, Slack, or Zendesk. Elle can help configure integrations from a natural-language description of what you need connected.

Aha! Builder Team and Scale plans include additional configuration options: governance controls, custom CNAME domains, and default rules that set policies across all applications in your account.

Test with real scenarios

Testing is where you confirm the application works for real tasks. Use Preview to walk through realistic scenarios before deploying to production.

  • Walk through complete workflows: Each scenario should reflect how someone will actually use the application.

  • Test with different roles: Switch between role types to confirm that permissions, visibility, and data access match what you designed. You might verify that a manager sees the right dashboard, a contributor can edit their data, and a restricted user cannot access what they should not see.

  • Invite collaborators for a second opinion: Use a developer guest pass to get a UX designer's or engineer's perspective on the application before it reaches end users. A second set of eyes can catch usability issues and technical concerns that the builder might not notice.

  • Run virtual user testing: Virtual user testing helps you resolve the obvious problems first, so real users can spend their attention on what only they can tell you. Click the Run virtual user testing icon in the Preview menu bar to send an AI-driven user through a workflow you describe. The test returns a report with screenshots, friction points, and prioritized recommendations. Click Create idea on any recommendation to add it to your ideas board.

  • Test integrations in preview: Verify that connected services send and receive data correctly before moving to production. Preview and production maintain separate configurations, so confirm behavior in both environments.

  • Prompt Elle to fix what you find: If a scenario reveals confusion or friction, describe the concern to Elle. Elle adjusts the application code based on your feedback.

Conduct security and privacy reviews

Before an application reaches production, it needs to earn the trust of your internal IT and security teams. Aha! Builder provides built-in assessments and governance controls that make this straightforward. When these guardrails are in place, deploying AI-built applications feels much less risky.

  • Run security and privacy assessments: Execute the four security assessments (secure by design, OWASP Top 10, static analysis, dependency scanning) and four privacy reviews (PII, GDPR, CCPA, cookies). Each assessment generates a report you can share directly with your IT and security teams. Note: If you have not already, run virtual user testing to identify gaps.

  • Have a developer review what you built: Invite a developer using a developer guest pass to review the generated code, inspect server logs, and validate the technical implementation. You can also export the code for an independent review before deploying.

  • Ask Elle to address feedback from reviews: If your IT team or developer reviewer flags issues, describe the concern to Elle. Elle adjusts the application code based on that feedback.

  • Review your account's governance policies: On Aha! Builder Team and Scale plans, governance administrators use the Governance area to establish controls across all applications. Default rules set accountwide policies for authentication, deployment, external access, and AI usage. Templates let administrators apply stricter controls to external-facing or regulated applications while keeping broader access for internal prototypes. The Governance -> Applications dashboard provides a portfolio-level view of every application's status, assigned rules, and security review completion.

Move to production

Aha! Builder handles the hosting infrastructure — your focus is configuration and launch readiness. Confirm the production environment is set up correctly before sharing the application with users.

  • Review the hosting environment: Aha! Builder hosts applications on AWS infrastructure with ISO 27001 certification, TLS 1.2/1.3 encryption in transit, AES-256 encryption at rest, and automatic certificate renewal. View the full hosting details under Documents -> Security -> Hosting in your application. Share this information with your IT and security teams as part of the deployment approval process.

  • Configure your production environment: Preview and Production are fully independent. Each maintains its own database, credentials, integrations, and logs. Changes in one environment do not affect the other. Configure production-specific authentication, integrations, and domain settings before deploying.

  • Choose the production URL: The default subdomain may be appropriate for an internal workflow. For applications that are more visible across teams or connected to an external audience, custom subdomains are available on Team and Scale plans, and custom CNAME domains on the Scale plan.

If your account uses admin-required deployment through Governance -> Default Rules, coordinate with the right administrator before your target launch date.

  • Confirm readiness before deploying: Verify that authentication and integrations are configured for production and that security and privacy assessments are complete. Aha! Builder uses blue-green deployment with automatic traffic reversion, so deployments are safe and reversible.

  • Share the application with users: After deploying, communicate the production URL and access instructions to your intended audience. Create an application user guide so end users can get started on their own. Elle can generate documentation from the application's current state, and you can refine the audience, tone, and section structure.

  • Monitor closely after launch: Use the Issues area to triage runtime errors and click Fix with AI to let Elle diagnose and resolve common problems. Track application usage to understand adoption patterns and identify areas for improvement.

Gather feedback and iterate

Applications improve when the people using them have a direct way to report what works and what does not. Build a feedback loop into the application so improvement stays connected to actual usage.

For applications where user research is critical, use Aha! Discovery to run structured user research and synthesize feedback at scale.

  • Enable the in-app ideas widget: Configure the widget under Operate -> Configuration in either your preview or production environment. Toggle the widget to Enabled, then customize the Title, Appearance, and Position so it feels like part of the application experience. End users click the widget to submit ideas and can then add a title, description, files, or highlight a specific area of the page with a built-in screenshot tool.

  • Triage feedback deliberately: Review submitted ideas under Implement -> Features -> Ideas. Use the status dropdown to categorize each idea. Deciding clearly which ideas to act on immediately (instead of sequence as planned improvements) keeps the application evolving without drifting from its original vision.

  • Build directly from feedback: Click Build on an idea to promote it to a feature and open Elle immediately. Elle reviews the application code and begins implementing the change — the fastest path from user request to working improvement.

  • Promote ideas that need planning: Click Promote to feature to add an idea to the features board for sequencing and scope. Use the board columns to manage planned work alongside new feature development.

In-app feedback collection is available on Aha! Builder Team and Scale plans. On the Pro plan, build a strong feedback loop using the features board and direct user conversations.

Applications that people actually use are rarely the most elaborate ones. They are the ones that solve a real problem, fit the way people work, and improve through steady feedback. This disciplined approach — from strategic evaluation through production and beyond — produces applications your team relies on every day. That is the real promise of Aha! Builder: not just that you can build quickly, but that you can build something worth keeping.
