Behavioural Training for High-Growth Startup Teams in the UK
In many startups, ideas rarely die at the desk. They die in the presentation room.
Not because teams lack ideas. Most startup teams are made up of curious, proactive individuals. Brainstorms are lively. Conversations move quickly. Ideas are already on the tab.
The challenge appears at a different moment.
When a team is asked to present a new idea to an owner, leadership team, or key stakeholder, and the idea is no longer judged by how interesting it sounds on a slide, but by whether it can be clearly explained and justified.
At this point, creative problem-solving is no longer about who brings the boldest idea; what gets tested is the one who is willing to speak up, not just throw ideas into the room, but explain why an idea is worth trying.
This is where many ideas stall, long before they are ever explored in real work situations.
If ideas are already there, the real question becomes which creative problem-solving skills are needed, and why they so rarely emerge in practice.
Creative Problem-Solving Skills UK Startup Teams Need in Practice
-
Staying with an idea
Ideas often fade once questions start to come. Not because they are weak, but because pressure makes people retreat too early.
-
Explaining the thinking
Teams share conclusions but skip the reasoning behind them. Alignment is assumed, then quietly breaks down later.
-
Challenging without friction
People notice risks but hesitate to speak up. The cost of being seen as difficult feels higher than the cost of staying silent.
-
Deciding without certainty
Everyone knows the data is incomplete. Decisions still stall because taking the risk feels uncomfortable.
Why Startup Teams in the UK Struggle to Act on Ideas
-
Under deadlines and scrutiny, teams often revert to familiar habits, even when better options are available.
-
Even in flat teams, senior presence shapes who speaks, challenges, or holds back.
-
Fast-paced work leaves little space to notice patterns, so behaviour repeats by default.
-
When outcomes feel risky, responsibility is avoided, and progress stalls quietly.
Why Mainstream Training Misses the Point for Startup Teams in the UK
Most mainstream training looks effective on paper. In reality, it often checks the wrong boxes.
☑ Familiar frameworks that sound right but rarely surface real behaviour
☑ Group discussions that stay polite and avoid real tension
☑ Learning that happens in safe rooms, not under real pressure
☑ High participation during sessions, low accountability afterwards
☑ Reflection without consequence once teams return to work
☑ Confidence in the room that fades back at the desk
Training is completed, but behaviour at work remains unchanged.
What Effective Behavioural Training Looks Like for Startup Teams in the UK
Behaviour is worked on directly, in real meetings and decisions, not discussed as theory after the fact.
Pressure is built into the process, so teams practise how they respond when deadlines, scrutiny, and consequences are real.
Reflection happens close to action, helping teams see how behaviour shaped outcomes while the context is still fresh.
Ownership is visible, making responsibility clear during decision-making rather than abstract or shared too loosely.
Change is reinforced over time through repeated practice, replacing old habits rather than relying on one-off sessions.
How Sidestream Helps UK Startup Teams Turn Ideas Into Action

Context
A UK startup team needed stronger creative problem-solving and more confidence in presenting bold ideas under pressure.

What happened
During the MARVELous Ideas workshop, teams were pushed to develop and pitch ideas quickly, in front of others, using unfamiliar creative constraints. The pressure exposed hesitation, self-editing, and a tendency to play it safe.

Behaviour shift
As the session progressed, teams became more willing to stay with ideas, explain their thinking clearly, and pitch confidently despite uncertainty.
Who this
Behavioural Training Is For
This behavioural training is designed for marketing, creative, product, and growth teams who already have ideas but struggle to speak up, explain their thinking clearly, or make decisions under pressure. It is most relevant when discussions stall in meetings, ideas weaken during pitches, or responsibility becomes unclear once real scrutiny and risk enter the room.
What Teams Said After the Session
About Ben Laumann and Sebastian
Ben Laumann
Ben Laumann works at the intersection of psychology, learning design, and human behaviour at work. His background in organisational psychology and theatre shapes how Sidestream designs behaviour change training that feels grounded, embodied, and closely connected to how people actually behave under pressure.
He holds advanced degrees in psychology, innovation, and organisational studies from University College London and the University of Cambridge, and continues to research organisational behaviour and learning design. Rather than relying on abstract models, Ben Laumann focuses on creating learning environments where behaviour can surface naturally and shift through experience.
Sebastian Flack
Sebastian Flack approaches behaviour change through a systems and pressure-informed lens. His work centres on understanding how people respond when stakes are high and how those responses can be reshaped through experience rather than instruction.
With academic training in social science and management, alongside four years of service in the German Armed Forces, including deployment in Afghanistan, Sebastian Flack brings a grounded perspective to behaviour change work. These experiences inform how he helps organisations recognise behaviour patterns and build more effective ways of working under pressure.
Frequently Asked Questions

The work happens in real-time discussions, pitching, and decision moments, rather than theoretical exercises or passive learning.
-
Yes. Sessions are shaped around the pressures, decision points, and challenges your team actually faces at work.
