The 2026 edition of Startup Innovation Weekend (SIW) is coming to Phnom Penh, bringing together visionary minds, deep tech, and capital on a platform built around innovation and opportunity.

Going beyond simple introductions, SIW connects regional startup ecosystems with the global stage, ensuring founders and investors walk away with tangible outcomes—term sheets, not just business cards. At its core, SIW’s 3Cs Framework—Connect, Celebrate, Collaborate—lays the groundwork for building and scaling the next generation of innovative startups.

Rooted in the legacy of the International Creativity & Innovation Award (ICIA), a global platform empowering innovators across 40 countries, SIW Phnom Penh 2026 carries forward a clear mission: harnessing the power of AI to build a more inclusive and resilient future for the ASEAN region.

Team Raintree is proud to co-host a segment of this event, and we’re excited to see what our community will create together.
