• Bive

  LeFil Consulting is supporting us on critical strategic topics and initiatives since 2017. Our team participated in the Gender Mainstreaming program, which resulted in the development of the Mujer Bive tu Salud Project, which promotes the early diagnosis of breast and cervical cancer in rural Colombia. Thanks to LeFil’s support, we subsequently received a CHF 10’000 grant from the Swiss Development and Cooperation that helped us launch the project and reach 500 women.  As a consequence of this first investment, we managed to raise additional funds and reached 1’750 women in the first year. We also benefitted from LeFil’s advice to strengthen our business model and create partnerships with investors and other entrepreneurs.  This support allowed us to greatly increase our impact and develop a partnership with other actors of the health sector, that will allow chronic diabetic patients to better understand their condition and to improve their quality of life.

  I had a more than satisfying experience with LeFil, as their workshop on ‘Leading with Data’ convinced me about the importance of using data to lead and improve our organization. Thanks to this training, my company is now better addressing its customers’ needs.

To fully understand the situation in Kazakhstan and the underlying problems that the region is facing, LeFil’s team did a very insightful field visit, led workshops, and ultimately helped us understand how to move forward. Thanks to their work, our Program was launched successfully.

• Altech

  Thanks to a competition that LeFil is facilitating on behalf of a large Swiss foundation, our company – Altech – got a grant that helped us grow significantly faster. But with this growth came a whole lot of questions and opportunities as for how to manage our sales force. LeFil obliged us to first gather data and facts about our current performance and approach, before developing any recommendations. On this basis, we evolved our sales strategy in a much sounder and confident way, rather than on gut feeling or experimental pilots. They also helped us improve our working capital management, an essential step in this new phase of our company. We are very grateful to LeFil for helping us laying the foundations for a successful expansion operation – both in terms of impact and business.

  Washikala Malango – Co-Founder and CEO – Altech Group

Through their analytical support, we will be able to quantify the value that CarePay unlocks for different stakeholders, which will help us strengthen our business case and sharpen our focus. We look forward to continuing to work with LeFil’s team!
