Yiem Raises Seed Funding from Expresso, a PTT Group Subsidiary

Yiem is proud to announce a seed investment from Expresso, a subsidiary of PTT Public Company Limited — Thailand's national energy champion.

This seed round of 1 million baht affirms what we've been building: smart, offline-first intelligence for the facilities, farms, and industries that keep our country running. Expresso — PTT's venture capital arm — invests in bold, purpose-driven ventures, and it has chosen to stand with Yiem.

What This Means

  • Validation — A strategic investor with deep roots in Thailand's energy and industry infrastructure believes in our vision.
  • Growth — This capital accelerates product development, market reach, and the teams serving our customers.
  • Alignment — Expresso brings more than funding; it connects Yiem to a national ecosystem of energy, sustainability, and industry.

Building for the Long Term

We build and operate alongside the businesses we serve — your success is our success. With Expresso on the journey, we're better positioned to deliver connected intelligence where it matters most, at whatever scale.

Thank You

We thank the team at Expresso and PTT Group for their trust, and our customers and partners who made this possible. This is not a milestone — it's a launchpad.

Expresso is the venture capital and investment subsidiary of PTT Public Company Limited, investing in innovative businesses that drive growth and sustainability for Thailand.
