From Black Box to Glass Box: Why We Raised €2M to Build a New Kind of AI Development Platform

Today, we are thrilled to announce that Leapter has secured €2 million in pre-seed funding to transform how enterprises build software. The round was led by bm|t beteiligungsmanagement thüringen GmbH with participation from SIVentures and a pool of angel investors. This investment will fuel the development of our visual-first platform, built to solve the critical trust gap in AI-generated code by ensuring human oversight is at the core of AI-driven development.

From a Black Box to a Glass Box: Making AI-Generated Code Enterprise-Ready

The promise of AI in software development is speed, but for any enterprise, speed without trust is a liability. The common belief is that AI will eventually get better at writing perfect code, but this misses the fundamental challenge: raw code itself is a black box, understood only by a technical few. Waiting for a better black box isn’t a strategy.

Leapter solves this trust gap by changing the medium entirely. The Leapter platform translates business requirements not into more opaque code, but into executable blueprints: structured, visual diagrams that serve as the single source of truth for a project.

This is Leapter’s core innovation. Unlike source code, which requires developers to act as interpreters, these visual blueprints can be directly understood, validated, and refined by the people who know the business best—from product leaders and business analysts to compliance officers and legal experts. It creates a shared language that bridges the dangerous gap between business intent and technical implementation, ensuring what gets built is aligned, secure, and correct by design.

This “glass box” approach is being recognized as a critical enabler for true enterprise AI adoption.

“For the past decade, enterprise IT has been about balancing speed with control,” said Phil Le-Brun, Director of Enterprise Strategy at AWS and former Global Technology VP at McDonald’s. “Generative AI presents a massive opportunity but simultaneously can introduce risk if it operates as a black box. Leapter’s genius is in its ‘glass box’ approach. It provides the auditability and human-in-the-loop governance that CIOs and CISOs need to confidently deploy AI-driven development at scale. It’s the missing link for enterprise-grade AI adoption.”

Why Leapter Is Different

While other AI tools focus on helping individual developers write code faster, Leapter’s platform is designed for true cross-functional collaboration. It empowers your business experts and key stakeholders to describe requirements in plain language, then visually review and refine the system’s logic alongside their technical colleagues. This unique, interactive process allows your organization to move from initial idea to production-ready system with unprecedented speed and alignment, eliminating the costly risks of traditional project handoffs.

This is possible through three core differentiators:

  • From Black Box to Clarity: Instead of producing opaque source code, Leapter generates clear, visual blueprints of the system’s logic. This turns complex processes into something anyone can understand, question, and validate.
  • Unite Business & IT: Leapter’s visual interface becomes the common language for your entire organization. Now, teams in Finance, Operations, Marketing, and Legal can co-create and approve solutions directly with IT, ensuring business needs are perfectly translated from day one.
  • Built-in Trust and Compliance: Every step, from the initial prompt to the final logic, is fully traceable. This provides the unbreakable audit trail required to operate with confidence in financially regulated and other mission-critical industries.

We saw teams getting stuck between the promise of AI and the reality of enterprise software development. You can’t just throw AI-generated code over the wall and hope for the best. That’s why we built Leapter around ‘executable blueprints’—to empower the entire team to build systems that are correct by design.” said Robert Werner, Co-founder and CTO of Leapter.

Meet the Founders

Leapter was founded by Oliver Welte and Robert Werner, two enterprise software veterans from companies like Pivotal, VMware, and Broadcom. Having witnessed firsthand how the gap between business intent and technical execution created risk and slowed innovation, they knew there had to be a better way. They created Leapter to build the solution they wished they’d had: a platform centered on clarity, collaboration, and trust.

Backed by Visionaries

Leapter’s funding round was led by bm|t beteiligungsmanagement thüringen GmbH , with support from SIVentures and angel investors including Frank Stummer, Roman Dudenhausen. Investors were drawn to the team’s clarity of vision and the urgent need for safer, smarter AI dev workflows.

“The market for AI development tools is exploding, but Leapter stood out immediately,” stated Stephan Beier, Senior Investment Manager at bm|t. “Oliver and Robert possess a rare combination of deep enterprise experience and a compelling vision for a new, more trustworthy development paradigm. Their focus on auditable, human-verifiable AI is not just a feature—it’s the key to unlocking the massive enterprise market. We are convinced that Leapter has the right team and technology to become a category leader.”

That sentiment is echoed by Leapter’s angel investors, who see the company as uniquely positioned to reshape how software is built.

Leapter is different. It doesn’t just help the developer; it helps the entire organization. By making business logic visible and verifiable, Leapter eliminates ambiguity and allows teams to ship complex features with unprecedented velocity and confidence.” said Frank Stummer, angel investor.

What’s Next

We are currently in private beta with incredible early design partners. With this new funding, we will be growing our engineering team to expand our visual language and launch more enterprise integrations. This is just the beginning of our journey, and we invite you to be a part of it. Join the beta!

We are incredibly grateful for the support of our investors and supporters, and we’re more committed than ever to solving the trust gap in AI. Thank you for being part of our story.
– Oliver and Robert
