Turn of the year at mAInthink - company vacations & outlook
For mAInthink GmbH, the year 2025 was characterized by intensive development work, strategic projects and the expansion of our AI-based solutions in the areas of strategy optimization, decision intelligence and machine thinking.
At the end of the year, we are deliberately taking a short break to bring the past year to a clean close and start the new year with a clear focus.
📅 Company vacations at mAInthink
Period:
19.12.2025 up to and including 05.01.2026
We are on company vacations during this period.
Our office as well as project and support communication will not be available during this time.
Inquiries & projects during the company holidays
- Inquiries by e-mail or contact form will be accepted
- Processing will take place from 06.01.2026
- Ongoing projects will continue as planned from the new year
In this way, we ensure that all topics are handled with the necessary care, analytical depth and strategic clarity.
Thank you for your trust & cooperation
We would like to thank our customers, partners and companions for their trust, openness and constructive cooperation over the past year.
From January 6, 2026, we will be back for you as usual - with fresh energy, new impetus and the clear aim of making complex decisions measurably better.
We wish you a peaceful holiday season and a successful start to the new year.
Yours
mAInthink GmbH Team
Sascha Rissel is an entrepreneur, founder and CEO of mAInthink GmbH, as well as a Board Member of KI Bundesverband Hessen and a WEF SME Member. For more than 20 years, he has been developing, scaling and optimizing technology-driven business models at the intersection of corporate strategy, technology and mathematical decision optimization.
With StratePlan, mAInthink is developing a Decision Intelligence solution for the mathematical optimization of CAPEX, capital allocation and investment portfolios in fixed assets. The objective is to calculate the optimal combination of investment projects under real-world budget, resource and dependency constraints, enabling organizations to generate greater impact from their existing capital.
Sascha Rissel's work focuses on CAPEX Optimization, Capital Allocation Optimization, Project Portfolio Optimization, Multi-Year CAPEX Strategy Planning and Live Boardroom Simulation. StratePlan combines mathematical optimization, algorithmic decision models and Hybrid AI to translate complex investment decisions into measurable business performance.
With CAPEX Live Boardroom Simulation, changes in budgets, priorities and constraints can be recalculated during a board meeting, alternative portfolios can be compared, and trade-offs can be made immediately visible. This transforms a sequential planning process into a new decision loop: question, calculation, comparison and decision within the same meeting.
Through the StratePlan Online Decision Service, Sascha Rissel also advances the concept of “Decision Intelligence 4 All”: making mathematical decision optimization accessible not only to large corporations, but also to mid-sized companies and the public sector.
Sascha Rissel regularly contributes his expertise through professional publications on Project Portfolio Management (PPM), CAPEX Optimization and Decision Intelligence. His work includes specialist contributions within the professional environment of the GPM German Association for Project Management, and he is a specialist author for ControllingPortal, writing about mathematically grounded approaches to investment, portfolio and corporate performance management.
His work focuses on measurable impact, transparent and robust decision-making, and transforming highly complex mathematical models into practical solutions for industry, business and the public sector.
His guiding principle: bringing strategy, technology and impact together consistently – and turning decisions into measurable performance.
