Bees & Bears — green energy financing platform client

Client

Bees & Bears, headquartered in Berlin, is building financial solutions that power the green economy.

Working alongside clean energy brands, the company embeds financing directly into its offers, which makes climate-friendly technology more accessible.

The model helps hardware providers evolve into service providers — removing the heavy upfront burden and offering customers flexible, recurring payment options.

Business Challenge

The company’s old financing process was slow and not good for growing the business.

Credit applications were processed through disconnected manual procedures. This approach extended approval timelines, elevated operational risk, and limited the company’s expansion capacity.

The goal was to design a unified platform capable of:

  • Digitizing the entire lending lifecycle end-to-end

  • Automating essential financial computations and decision logic

  • Embedding smoothly within partners’ sales environments

At the same time, the user experience had to remain straightforward while complying with strict German financial and regulatory standards.

The initiative required:

  • A secure, cloud-native system architecture

  • Seamless integration with a Germany-compliant KYC provider

  • An API-centric framework designed for long-term scalability

  • Support for both internal operations teams and external business partners

The resulting solution needed to deliver reliability, regulatory compliance, and sustainable technical performance.

Solution

We architected and delivered a scalable web platform that automates the full credit application journey.

Core Objectives

  • Replace manual lending routines with a unified digital workflow

  • Deploy an automated financial decision engine

  • Embed identity verification within the user flow

  • Establish a secure AWS-based infrastructure prepared for rapid growth

  • Release a fully operational MVP within a tight delivery window

Platform Capabilities

  • End-to-end web portal for credit application management

  • Real-time automated financing calculations

  • Integrated KYC functionality for swift identity confirmation

  • Centralized backend managing process orchestration

  • Secure AWS cloud deployment

  • API-driven architecture ensuring seamless integrations

The outcome is a high-performance lending engine that removes friction from clean tech sales processes.

To deliver a fintech solution quickly, we needed a cross-functional team. This team had to have strong skills in financial systems and scalable web development.

Delivery team included:

  • A project manager to oversee the project and communicate with stakeholders.

  • A business analyst is to define workflows and rules.

  • A solution architect to design the system.

  • Frontend engineers to build the user interface.

  • Backend engineers to build the logic and APIs.

  • A cloud engineer to optimize and secure the cloud environment.

  • A QA engineer to test the platform.

Behind the intuitive interface stands a scalable and resilient technical foundation.

Web Application

  • Built with React.js and Next.js

  • Responsive interface tailored for internal users and external partners

  • Structured application flow with dynamic real-time logic validation

Backend Architecture

  • Developed in Python and TypeScript

  • REST API and GraphQL API endpoints

  • Custom-built automated interest and financing engines

  • Advanced orchestration managing credit workflows

Integrations

  • Direct API integration with a German-certified KYC service provider

  • Modular structure enabling future system expansions

Cloud Infrastructure

  • Hosted on AWS for high availability and reliability

  • Data governance aligned with banking-level security standards

  • Elastic environment capable of handling transaction surges

Discovery & Requirements Definition

We thoroughly reviewed the existing manual financing workflow to grasp every operational detail and regulatory requirement. The goal was to turn this hands-on process into a clear, organized digital system that can be automated.

MVP Development

In just 2.5 months, our team delivered a feature-complete MVP that met the initial budget. The release included automated underwriting, integrated identity checks, and a live cloud environment.

Testing & Stabilization

Quality assurance concentrated on:

  • Accuracy of all financial computations

  • System performance under elevated user loads

  • End-to-end data protection and encryption

Following validation, the platform was prepared for full operational deployment.

Value Delivered

By digitizing the client’s core financing engine at an early growth stage, we created the technological foundation necessary for rapid expansion.

Key Outcomes:

  • Shifted from manual processing to a unified digital system

  • Automated the financing rules to eliminate calculation errors

  • Deployed a cloud setup designed for increasing volumes from day one

  • Removed technical barriers to support rapid portfolio expansion

  • Since the platform launch, Bees & Bears has continued to scale. By early 2025, the company had secured a €500M credit facility for clean energy plus new equity funding.

Since we built the core infrastructure to scale from day one, Bees & Bears was ready to handle these volumes and meet institutional requirements immediately.
