Longwave Financial helps thoughtful New Yorkers build ESG and sustainable investing portfolios with purpose and confidence. You get a financial life that reflects your values, managed by an independent asset management team that genuinely cares.
You donate to causes that matter. You research the brands you buy. You notice the impact technology has on the world around you. But when it comes to your investment portfolio, do you actually know what your money is funding?
Most people don't. And most financial firms don't think to ask.
At Longwave, that question is where every conversation starts.
Here is what makes working with Longwave different.
Legally required to act in best interest when providing financial advice.
No bank owns us. No insurance company influences us. We give you honest advice.
ESG and sustainable investing are not a product we sell. It is the reason we exist. We have been doing this for decades.
ESG stands for Environmental, Social, and Governance. But what it really means is this: your money goes into companies that meet a higher standard. Businesses that care about the planet, treat people fairly, and are run with integrity.
We do not just take funds at their word. Longwave uses independent, third-party data from USSIF, YourStake, and As You Sow to verify that every investment actually lives up to its values, not just its label.
Many funds call themselves sustainable but hold exactly the kind of companies you would want to avoid. We dig deeper, so you do not have to wonder.
Want your investments to reflect your values, not just your net worth.
Are curious about ESG or socially responsible investing, but not sure where to start or who to trust.
Are navigating a major life change and want a plan that reflects who you are now.
Are tired of being overlooked or talked past by traditional financial firms.
Want one trusted advisor who coordinates your full financial picture: taxes, retirement, giving, and more.
You tell us what matters to you: your life, your goals, your concerns. We listen without judgment or agenda.
We create a personalized financial plan and ESG portfolio that reflects your values and your goals. Every recommendation is backed by data and tailored to you specifically.
This is not a one-time transaction. We are your long-term partner, coordinating across your entire financial life and adjusting as your needs evolve over time.

The leading voice for sustainable, responsible, and impact investing in the United States.
We commit 1% of revenue to environmental causes, because our values do not stop at your portfolio.
It is the most common question we get. The answer is no.
Our team uses decades of research and rigorous third-party data to build ESG portfolios with the goal of performing with purpose. We do not believe you should have to choose between doing well financially and investing in a world you believe in. That is the entire reason Longwave exists.
Let's start with a conversation.
Tell us a little about where you are, and we will take it from there. No pressure, no pitch.
