Same projects. Different combination. Greater results.
You can achieve higher returns with your existing projects.
We calculate the optimum scenario - before you decide.
Free of charge. Without obligation. Based on your existing projects.
StratePlan calculates the optimal portfolio where traditional tools reach their limits.
Instead of evaluating projects in isolation, we analyze all possible combinations - and identify the best solution.
The global optimum is not an assumption - it can be calculated.
Millions of decisions are based on assumptions:

Project portfolio optimisation, strategy optimisation, project management, maximum ROI and optimal financial plan for the best business decisions.
Welcome to the mAInthink AI blog - the knowledge platform for all those who want to optimise strategic decisions, project portfolios and company resources based on intelligent algorithms rather than gut feeling.
In a world of growing complexity, traditional methods such as Excel, linear business plans or isolated KPIs are no longer sufficient. Projects compete for budgets, measures influence each other and the optimal path is rarely obvious. This is exactly where our blog comes in.
What our AI blog is about
The mAInthink blog is all about strategy optimisation, project management optimisation, business efficiency and, above all, one thing: MAXIMUM ROI with limited resources.
We show how modern AI and optimisation methods help to make better decisions - even when hundreds or thousands of options have to be evaluated simultaneously .
- How can projects be optimally prioritised?
- Which measures generate the greatest impact?
- Where do hidden synergies or cannibalisation effects arise?
- When does traditional planning fail - and why?
- How can ROI be rethought beyond traditional key figures?
Our focal points
Strategy optimisation with AI
We analyse how hybrid AI and algorithmic machine thinking are redefining strategic decisions. Instead of evaluating individual measures, we look at the entire decision-making space - including dependencies, risks and long-term effects.
A new approach to project management
Traditional project management reaches its limits as soon as several projects are running in parallel. In our blog, we show how AI-supported project portfolio management clarifies priorities, protects budgets and reduces implementation risks.
Business efficiency & resource utilisation
Efficiency doesn't mean saving - it means investing correctly. We shed light on how companies utilise their resources where they have the greatest strategic impact.
Maximum ROI - redefined
ROI is more than just a key figure. We show why traditional ROI calculations are often misleading and how modern algorithms integrate impact, risk and time into a holistic decision-making logic.
Who is the mAInthink AI blog for?
Our blog is aimed at
- Managing directors, board members and investors
- Strategy and transformation teams
- Project and portfolio managers
- Decision-makers in public administration
- Organisations with complex decision-making spaces
In short: For everyone who needs to make better decisions faster.
Practical. Analytical. Forward-looking.
All articles in the mAInthink AI blog are based on real projects, scientific findings and practical experience with our systems such as StratePlan and DeepAnT.
Our aim is not to comment on trends - but to provide with concrete thinking tools to help you manage your organisation measurably better.
Welcome to the mAInthink AI blog.
This is where strategy is calculated - not guessed.
