Sonja Keerl, one of the original founders of the MACH Alliance, joins the show to share her unconventional opinions on technology, ethics, and the future of commerce. By day, Sonja helps B2B SaaS companies with strategy, messaging, and positioning. By night, she is busy creating "Unomundi", a network for children to explore different cultures.
The conversation starts with Sonja's thoughts on how tech professionals have negatively impacted the internet and social media for the next generation. The hosts pivot to Sonja's role in co-founding the MACH Alliance in 2019, before the start of the COVID-19 pandemic. She explains the alliance started in a London pub, to unite best-of-breed vendors and offer a flexible, agile alternative to the dominant monolithic platforms. The discussion covers the distinction between headless and composable, with Sonja using children's toys to illustrate how composable software needs interoperability standards to truly be effective for brands. Finally, Sonja discusses the current state of composability, the challenge of SI lock-in, and her vision for an AI-driven, automated future for buying commerce software.

Show Highlights:
-
The origin story of the MACH Alliance
-
Understanding the difference: Headless separates presentation from content; Composable is modular software for specific business needs, but true freedom requires interoperability.
-
The composable industry faces a challenge with "SI lock-in," where System Integrators provide the "glue" between systems and retain the intellectual property.
-
The collision of AI and composability: modular vendors are uniquely positioned to leverage agents for back-end efficiency and goal orchestration across multiple systems.
-
AI-driven interoperability is the next race and can make composable solutions feasible across different maturity stages in the coming years.
