Meet The Lightbulbs


Grace Teoh, Chief Data Organiser & Excel Addict

Hi, that's me smiling nerdily.

In 2016, I started Lightdotlab with the idea of helping businesses and individuals better achieve their goals. At Lightdotlab, we believe using data insights is key to guiding successful business decisions. We have collaborated with various companies including Changi Airport GroupScoot, Topology Travel and Wobe; from developing business models and reports, to providing end user trainings.

Having worked as a business analyst, I specialise in building models and reports that can be changed on-the-fly, to facilitate C-level decision-making. My expertise is fuelled by my motivation to constantly discover better, faster, and more accurate ways to improve business analysis and modelling. Enabling people to get the most out of their data is what excites me the most!

If you'd like to chat about consulting and training opportunities, simply drop me a line or let's grab coffee!


Jasmin Choo, Growth Strategist

Don’t be fooled by that coy grin (we were, at first!).

Jasmin prefers to live life on the “spicy” side: full of food, travel and spark. Her constant globetrotting has honed not only her skills as a people-person, but also the ability to work seamlessly anywhere.

Through her experiences, she has found that the key to good communication is to keep things simple. Her advice: always try to be relatable on a personal level. 

As our Growth Strategist, Jasmin takes heart in making sure we stay on top of our game. Her diversified experience in risk management, marketing, and journalism provides Lightdotlab with unique perspectives on how to serve our clients better.

According to Jasmin, Lightdotlab fulfills her idea of helping people in the littlest ways, but with big impact.


Sabrena Jefri, Communications Strategist

We may state the obvious but, Sabrena loves to lead life out of the box.

Whether on a motorcycle in Jakarta, a kopitiam in Singapore or by the Seine river in Paris, she lives by the old saying: life is a story waiting to be told.

She keeps the same approach when it comes to her work style. To her, all stories are worth listening to -if you tell it right. With her strong background in hospitality, marketing and PR, Sabrena lends us her expertise as a skilled communicator. She also speaks 5 languages and hopes to be able to order ramen in Japanese someday.

At Lightdotlab, Sabrena strives to shine light (note her pun) on our purpose, vision and values. Secretly a fan of Marie Kondo, she firmly believes being efficient is about continuously improving your processes, with adequate knowledge and tools.


Why People Love Us

Those we've trained :

"the training was grounded by practical experience, thus helping me quickly apply what I learnt to my daily work and deal with the “messy” real-world situations."

- Tay Xue Ping, Consumer & Marketing Insights Specialist 

"Grace was a patient and approachable mentor! She taught us how to build "clean" models and generously shared her knowledge of Excel. Now, I am able to develop models that can quickly simulate scenarios during management meetings! It’s a great relief no longer having to scramble each time someone wants to change an input assumption."

- Ong Si Yun, Pricing and Commercial Strategy

"If you want to learn how to storytell effectively with data, Grace will be your go-to person. I liked that she focused on the “why”s because once I understood it, I was able to intuitively apply the principles. She inspired me to question my motivation behind my design choices, and made me a better communicator!"

- Jade Lim, Consumer  & Marketing Insights Specialist

Those we've consulted for :

Grace has helped us identify our critical operating metrics and displayed those performance metrics on visually-rich graphs, allowing the relevant departments to understand our operating situation immediately. With this, instead of a reactionary response to changes in economy, we can now take preventive measures earlier."

- Steve Shih, Topology Travel, Taiwan

"With Grace's help, we've managed to identify which part of the business needed improvements and through the breakdown of data, we have also managed to measure and analyse our performance."

Dennis Teo, Breathe Pilates, Singapore

"Grace’s work has made life so much easier for my team! The revenue tracking and forecasting model she developed for us was a breeze to use. It allowed us to get a good sense of where we are in just one glance, and to plan our next steps.

-Jay Lim, Socio Vitae, Singapore
