Corporate and error culture with Jelena Klingenberg (hppypple)
The corporate culture in start-ups represents the heart of this dynamic form of company, which is characterised by innovation, flexibility and a unique team spirit. Startups are characterised by their ability to react quickly to change, implement new ideas and continuously develop.
But how do you build a corporate culture and get your employees excited about it? We get to the bottom of this question with two experts. Firstly with Jelena Klingenberg, founder of the HR start-up hppypple from Bingen, a full-service HR agency that takes care of its customers’ HR needs. This naturally includes building a corporate culture, the recruitment and application process and day-to-day issues in dealing with employees. We also spoke to systemic coach Gentiana Daumiller, who comes from Koblenz and is an expert in the field of error culture, among other things. We spoke to her about the challenges and issues surrounding the topic of ‘mistakes’. She gives us an insight into her day-to-day work and explains why and how mistakes help start-ups move forward.

Team phases according to Tuckman
🔄 The Five Team Phases According to Tuckman
Developed in 1965 by psychologist Bruce Tuckman, this model describes how teams typically evolve. Originally it included four phases, with a fifth added later:
1. Forming (Orientation Phase)
– Team members get to know each other
– Roles, expectations, and goals are still unclear
– Polite interactions, minimal conflict
2. Storming (Conflict Phase)
– Tensions arise (e.g., due to different work styles or unclear goals)
– Roles are challenged
– Important: Address conflicts openly without escalation
3. Norming (Regulation Phase)
– The team agrees on rules and structures
– Trust builds, collaboration becomes smoother
– Roles and responsibilities are clarified
4. Performing (Performance Phase)
– The team works efficiently and independently
– Goal-oriented collaboration at a high level
– Creativity and productivity emerge
5. Adjourning (Closure Phase) (added later)
– Team is dissolved or restructured
– Reflection, farewell, and transition planning

🚀 Relevance for Startup Teams
📌Raising awareness: Founders benefit from knowing these phases – it helps them understand and actively guide team dynamics.
📌Normalizing conflict: The storming phase is natural – when handled consciously, it strengthens the team in the long run.
📌Team leadership: Founders can actively support the process through clear communication, feedback culture, and role clarity.
📌Resilience building: Teams that grow through these phases often develop strong foundations for future challenges (e.g., rapid scaling or investor interactions).
📌Exit or scaling situations: The adjourning phase may occur during team transitions or exits – effective management here protects know-how and team culture.

FAQ - Frequently asked questions
When does it make sense to start thinking about HR and corporate culture in a startup?
Many founders wonder whether HR only becomes relevant once a company reaches a certain size. In fact, it is worth establishing clear rules and values from the moment you hire your first team member. Otherwise, unspoken expectations or unclear roles can creep in, which are difficult to correct later on.
What areas of activity should HR cover in the early stages?
People often think of HR as just recruiting. But in startups, there is more to it than that: contract drafting, onboarding, feedback processes, training, and promoting a healthy team culture. It is enough to approach these issues pragmatically at first – the main thing is that they are not left to chance.
What typical mistakes do startups make when building HR and culture?
Often, HR is established too late, there is a lack of transparency in decision-making processes, or conflicts are ignored. The issue of “team fit” is also often underestimated—if values don’t match, tensions can quickly arise.
Why are shared values so important for collaboration?
Values are the foundation on which decisions, collaboration, and communication are based. When a team shares the same basic principles, conflicts can be resolved more quickly and goals can be pursued more clearly. Without value alignment, even small differences of opinion can escalate.
How can values and purpose be practically incorporated into the team?
It is not enough to write down values – they must be visible in everyday life. This can be achieved through rituals (e.g., regular retrospectives), leadership by example, and clear rules for working together. Purpose helps to derive priorities: What skills do we really need to achieve our purpose?
How do I actively build a corporate culture?
Culture does not just happen – it can be shaped. Start with a discussion in the team: What values do we want to live by? What behaviors fit with these values? Use Tuckman’s team phases (forming, storming, norming, performing) to understand what stage of development you are currently in.
What are the benefits of a consciously designed corporate culture?
A strong culture increases motivation, loyalty, and productivity. It helps with recruiting (attractive employer brand), facilitates decision-making, and provides orientation in uncertain phases. Example: error culture. When mistakes can be discussed openly, teams learn faster and innovate more.
How can I ensure that applicants really fit into the team when recruiting?
In addition to hard skills, you should check soft skills and values. Questions about motivation, cooperation, or dealing with conflicts are helpful. Also watch out for warning signs of toxic behavior. Methods such as the “no interruption rule” in interviews show whether applicants bring respect and team spirit to the table.
What is employer branding—and why is it important for startups?
Employer branding refers to how your startup is perceived as an employer. Small teams in particular benefit from clearly positioning themselves: What values, culture, and working environment do we offer? Positive employer branding attracts suitable talent and reduces turnover.
What is the difference between “praiseworthy” and “blameworthy” failures?
“Praiseworthy failures” are mistakes that arise from courageous experimentation and yield valuable insights. “Blameworthy failures” are avoidable mistakes that arise from negligence, lack of communication, or ignoring rules. A good error culture praises the former and minimizes the latter.
What does “fail fast, fail early” mean for my team?
The idea is to test assumptions quickly instead of spending a long time planning in secret. Small, early failures are less costly and provide faster feedback. This reduces the risk of large, expensive mistakes.
How can recruiting be supported digitally without losing the human aspect?
Digital tools (e.g., applicant management systems, online interviews) facilitate the process, but should not replace face-to-face interviews. Cultural and value issues in particular are better recognized in direct exchanges. Analog and digital elements can be combined: first online pre-selection, then a personal team interview.
