“Tangible results within 2 weeks”

Sander from TMI helped us to kick start our team from day one to the launch of our product: Tikkie. Sander helped us to get the right Agile and Lean mindset, and guided the Tikkie team from the first rough product iteration after already 2 weeks to a full Market Launch after 4 months.

TMI was the best choice that I could have made for Ligo. Sander and Paul are committed, hard working and very knowledgable. They are reliable partners who do not stop before you have a revenue-generating product.

“They will be a long time partner”

We work with TMI because they quickly assessed the needs of the Begiving App by giving us useful insights on improving our product as well as on the marketing side. They will be a long time partner.

Where most entrepreneurs keep overthinking their ideas for years and years, TMI knows how to transfer an idea into a product, validate and build a business superfast.

For Fietsy, we chose to partner with The Main Ingredient because they provide a combination of in-house design, development and pragmatism. This helps us immensely to accelerate Fietsy and launch the product fast. We're very happy we made this decision and to work with these guys.
