Mission:
Our team at ESM is committed to helping innovative Clean-Tech, Water-Tech, and climate-conscious organizations to cost-effectively optimize their growth. With a keen focus on driving highly qualified opportunities and progressing these opportunities through the pipeline, we aim to collaborate with your team, compress the sales cycle, and accelerate revenue and investment growth.

Our Approach
Hiring a new SDR or AE always carries risk — will the investment of your time and capital drive real results? Especially in critical sectors like water-tech and clean-tech, where every opportunity contributes to building a cleaner, more sustainable future, that risk is even more important to manage carefully.
At ESM, our team of experienced sales professionals brings a deep understanding of the water and clean technology landscapes, helping organizations that are stewarding Earth-focused innovations successfully commercialize and scale. We've helped drive over $100 million in revenue for our clients, enabling them to achieve critical growth milestones and secure future rounds of funding.
By engaging our team on a flexible, month-to-month basis, you can lower your overhead while strengthening your sales development process—ultimately accelerating the creation of highly qualified opportunities and driving revenue growth. If you are building your internal sales team, we can seamlessly integrate with them, sharing proven best practices and helping you amplify your impact in these essential industries.
