A Note From Sandy 


Sandy Stewart
Founder, Think Big

My name is Sandy Stewart, and I'm a Social Impact Strategist, Carbon Footprint Specialist, and Value Growth Expert. I'm the owner of Think Big, a strategic sustainability agency based in Austin, Texas that helps small- to medium-sized businesses create and sustain value growth. I have over 20 years of experience working with SMBs and SMEs, first as a Business Coach and then further specialized as a Value Growth Trainer & Consultant. In addition, I have the Sustainable Leadership Institute Certification from the University of Cambridge, as well as Shirlaws Coaching certification and a CoachU Graduate certificate. 


I'm passionate about helping businesses uncover their unique value offering and develop sustainable strategies that leverage their strengths and resources. My mission is to help businesses create value in the short-term and long-term, while also finding ways to reduce their carbon footprint. With Think Big, I work closely with clients to build an individualized strategy that works for them--one that can evolve as their business does.

Now, About You…

Whether you are a business owner, a startup entrepreneur, a manager looking for sustainability leadership skills or a business coach looking to break into the eco-minded market…

all innovators and climate heroes welcome here! 

People like us are driving sustainability and net zero for
3 main reasons: 

You want to future-proof your company

Given the pace of change with public policy, consumer buying trends, younger labor force, Scope 3 trickle-down effect (ask me about this one!) and raw material volatility, every business will feel the pain of at least one or more of these. Whether it’s this year, next year or 3 years from now, it’s not a question of ‘if’, it’s a question of ‘when’. 

You want the competitive edge

Knowing that eventually all businesses (in ALL industries) will transition to sustainable practices and a net zero path, being one of the first in your field will solidify your brand ‘on the leader board’. 

You want to make a big positive impact on the world

Let’s face it. Your pioneering passionate spirit is not going to stop you from making a positive impact and paving the way for others to follow. You want to create impact by shrinking your footprint, going circular, using sustainable partners or activating leadership in your communities. Maybe all the above! 

Why are YOU waiting?
(now that you know it will help you lower costs, tap into new markets and mitigate risks)

"Our company is too small to make a difference"

Truth is NO business is too small. Even solo-preneurs can make a difference. Companies with nothing but remote workers can make a big difference too.  

You might be surprised at some cost-saving you might uncover as well.

And with over 30million small businesses in the US, you can join the movement to be a small business front runner. Together we can inspire a revolution!

“Change takes time, and we’re already too busy trying to run the business”

I've found that most if not all small businesses do not have anyone in the business assigned to the task of sustainability. Nor do they have anyone with time to spare! 

Exactly why bringing in affordable outside support to help you get started. Let me ,with the help of my team, take the lead for you. 

We can get you started and when you're ready, we can train you or one of your team members on how to manage it seamlessly moving forward

“We already sell a sustainable product, so we don't need to build sustainability in our operations too”

     Yesss! So happy to see so many new sustainably designed offerings everywhere. But even companies built around a sustainable offering should ALSO look at instituting sustainability.


As conscious consumerism grows, so does the need to 'walk the talk'. In fact, it’s your best way of promoting what you believe in!

"You are going to learn things that you would never even think to try to learn, because you don't know what you don't know.  If you’re really good at your skill, but you’ve never run a business before, I don’t know how you’re going to sustainably grow your business without doing something like Think Big."
