Example: Mr. Simon — AI career coach

Mr. Simon transformed interview preparation, helping thousands of job seekers worldwide land jobs — while delivering powerful recruitment automation and data-driven insights for recruiters and hiring teams.

Learn More at Mr. Simon.ai

Mr. Simon began as a conversational AI interview coach, helping job seekers practice and refine their answers through real-time speech recognition, instant feedback, and advanced NLP.

Since then, it has expanded into an innovative B2B platform, offering automated resume screening, integrated hiring workflows, and actionable analytics for recruiters and HR departments.

The Challenge

Job seekers often struggle with interview anxiety and lack consistent, high-quality feedback to improve.
Meanwhile, recruiters and hiring teams face time-consuming manual screenings and a high volume of applications, making it difficult to identify the right talent quickly and objectively.

Specific Pain Points

  • For Job Seekers (B2C): Difficulty finding affordable yet tailored, on-demand interview practice and feedback.
  • For Organizations (B2B): Overwhelmed by application volume, hiring teams lose countless hours to tedious screening, inevitably overlooking great candidates hidden in the pile.

Our Approach

We adopted rapid prototyping and an iterative feedback loop, validating each feature directly with real users — job seekers, career coaches, and talent acquisition professionals.

01 Research & Discovery

  • Conducted interviews with career experts and recruiters to understand key challenges.
  • Mapped user journeys to identify friction points in both B2C coaching and B2B hiring workflows.

02 AI-Driven Prototyping

  • Integrated speech-to-text, text-to-speech, and advanced NLP and LLM models for real-time interaction.
  • Quickly tested new features — like tailored feedback modules and automated scoring— with a subset of beta users.

03 Iterative Refinement

  • Analyzed usage data to refine question generation, feedback accuracy, and user experience.
  • Incorporated feedback from recruiters and hiring managers to add resume-screening capabilities and ATS integration.

Results & Impact

B2C - Mock interview version

  • Enhanced Interview Confidence: 80%+ of surveyed users reported feeling more prepared and less anxious.
  • High Engagement and NPS: Gamified approach and instant feedback led to a 25% increase in repeat usage and word-of-mouth referrals.

B2B - Candidate evaluation version

  • Faster Time-to-Hire: Automated resume and interview screening reduces manual screening tasks by up to 10x while boosting quality at the same time.
  • Improved Candidate Matching: Flexible and transparent scoring mechanism allows recruiters to include criteria that really matter.
  • Equal Chance: Every applicant is evaluated on an equal footing, enabling more accurate identification of top talent.
  • Stronger Employer Brand: Respectful and empathetic candidate experiences boost employer reputation.

Key Technological Innovations

Real-Time Conversational and Video Interface

  • Speech-to-Text: Converts user responses on the fly, allowing instant analysis and feedback.
  • Text-to-Speech: Delivers questions audibly, providing a more natural and immersive practice experience.
  • WebRTC: Creates fluid, instantaneous conversational video interactions.

Advanced NLP & AI Feedback Loop

  • Immediate, Iterative Coaching: Provides personalized suggestions based on user input and performance—mimicking a human coach’s insights.
  • Resume Evaluation Algorithms: Analyzes candidate resumes, highlighting relevant skills and potential red flags.
  • Candidate Interview Evaluation: Assesses interview recordings, providing rubric-based scores and insights for recruiters.

02 | Modernizing Existing Systems

We are experienced in taking over and modernizing existing applications—often aging or undocumented—so your business keeps running smoothly. Through an incremental approach, we tackle critical upgrades, boost performance, and reduce technical debt without risking downtime.

Once modernized, we stay on board for ongoing stability, support, and new features as your needs evolve. Each improvement aligns with both immediate goals and future innovations like AI and automation.

  • We assume ownership of legacy codebases at any stage and stabilize them for long-term reliability
  • We refactor critical modules for enhanced performance, security, and maintainability
  • We add new features and functionalities over time to keep your systems competitive
  • We integrate AI and automation where they add real value and efficiency
  • We provide ongoing support to ensure your platform remains secure, scalable, and up to date

H Rewards: Elevating Hospitality Through Technology

Learn more at H Rewards

H Rewards is a hospitality platform that unifies loyalty, booking, and guest services. Over a multi-year collaboration, our team helped build a robust, high-performance system that handles 80M+ EUR in annual revenue.

The Challenge

Hospitality demands real-time data—from availability, rates, and inventory (ARI) to loyalty and payments—all integrated across multiple systems. H Rewards needed to modernize its booking engine, connect with enterprise software (Salesforce, Oracle Opera, custom PMS/CRS), and support quick content updates without sacrificing speed or reliability.

Our Approach

Collaborating closely with the product team and design agency, we architected a high-performance, scalable backend capable of handling real-time data demands. We focused on robust API development for seamless integration with critical enterprise systems, while ensuring the new booking engine delivered both speed and reliability from day one.
