Singapore-based startup OnSite has raised S$1.7 million in a seed funding round. The round was co-led by Tin Men Capital and Alter Global. Other participants include Hustle Fund and Gondor Capital.

The company plans to use the funds to expand its engineering team. In addition, it aims to improve its AI-based communication platform designed for construction and facilities management teams.


Addressing fragmented communication in construction

Construction teams often rely on informal tools such as messaging apps, calls, and manual records. As a result, information can become difficult to track. This may lead to delays, disputes, and inefficiencies, particularly for small and mid-sized contractors.

OnSite is attempting to address this issue through a structured communication platform. The system allows users to share voice notes, images, and text. At the same time, it automatically organises this data by project, location, and timeline.

Moreover, the platform supports multiple languages used across Southeast Asian worksites. These include English, Mandarin, Tamil, Bengali, Cantonese, and Malay. Therefore, it aims to simplify communication in multilingual environments.


Market context and industry challenges

Singapore’s construction sector remains a significant contributor to the economy. Industry demand is projected to reach between S$47 billion and S$53 billion this year.

However, inefficiencies remain a concern. OnSite estimates that digital gaps cost the sector over S$1.1 billion annually. Globally, fragmented workflows and poor data management continue to create larger financial losses.


Founders’ background and product approach

OnSite was founded by Poh Yong Han and Liam Appelson. Both founders have prior exposure to construction through family businesses in Singapore and New York.

Their approach focuses on usability. Specifically, the platform is designed for workers who may not have formal technical training. This becomes important in environments where teams frequently switch between languages.

According to the founders, construction communication often remains unstructured and difficult to retrieve. As a result, projects face delays and disputes.

To address this, the platform aims to link every message, image, and voice note to a specific time and location. This reduces the need for manual documentation and improves traceability.


Product development and roadmap

The company is currently testing its product with partners in Singapore and Hong Kong.

Looking ahead, OnSite plans to introduce additional features. These include:

  • AI assistants trained on construction data
  • Project analytics tools
  • Predictive risk assessment features
  • Integrations with third-party platforms

Investor perspective and sector trends

For Tin Men Capital, the investment aligns with its focus on business software and frontier technologies in Southeast Asia. The firm has previously backed construction technology companies such as Hubble and Ailytics.

Despite the sector’s size, construction technology funding in Singapore remains limited. Data cited from Tracxn shows that the sector raised S$3.2 million across two rounds last year. Over the past decade, total funding reached S$140.7 million.

This relatively low investment contrasts with the scale of global inefficiencies. OnSite estimates that poor data and fragmented workflows cost the global construction industry S$2.47 trillion in 2020.


Focus on usability and adoption

The company’s product strategy centres on ease of use. The founders emphasise that the platform should work without formal training.

At the same time, the system is built to handle enterprise-level data processing in the background. This balance between simplicity and functionality remains a key focus area.

Investors also note that construction firms require tools tailored to regional workflows and cultural contexts. As digital adoption increases, demand for such solutions is expected to grow.
