About Symphonic Capital

Symphonic Capital is an early-stage venture firm backing AI-enabled companies building the essential systems households depend on—across health, wealth, and climate resilience.

These systems are under increasing strain. Climate disruption, economic volatility, and fragmented healthcare aren’t temporary challenges—they are permanent structural shifts. We believe AI, when thoughtfully embedded, can act as adaptive infrastructure: lowering costs, reducing friction, and enabling systems to respond faster and more intelligently—especially for communities that have historically been overlooked.

We don’t invest in AI for its own sake. We invest in AI as a tool for access, resilience, and equity.

What We Believe

Symphony (n.) – means coming together of different types of instrumentalists, craftspeople at the top of their game, to create beautiful harmonies and movements.

We take an abundance mindset to investing. That’s because we believe there’s enough room for everyone to succeed and when we pool our collective resources we all win. We want to collaborate with our peers to help elevate the voices and visions of founders who are on a mission to do good. The more we work together, the better our chances of success. 

Our Story

2022

Sydney Thomas, our founder and GP, has been a vanguard of Pre-Seed investing. After 7 years of investing and being in the trenches with founders, she launched Symphonic Capital in 2022.

Symphonic was envisioned and designed from bold principles. Sydney’s collection of insights on the inner workings of top companies – as well as the most painful struggles – inspired her to build a firm that serves as a true partner to founders.

In forming Symphonic, she pulled in experts who were already dedicated to solving nascent companies’ problems in their respective fields in People/Talent, Business Operations, etc. Building a startup requires constant, effective collaboration, and it’s no different for us.
Builders will always want to work with other builders, and we’re here to help you succeed.

Our Team

More powerful, together. We’re a small but mighty team dedicated to helping founders reach their highest ambitions and become the best leaders they can be.

Our Community

We’re building a diverse community that reflects the change we want to see in the world. The current venture capital industry doesn’t represent the world around us. Instead, it’s been operated by the perspectives of a select few. Symphonic is on a mission to elevate the perspectives of founders, investors and LPs who have a diverse set of lived experiences and are dedicated to solving problems that impact the majority of people.

We are backed by leading institutions like Known, Candide, Illumen Capital, Bank of America, and Sweater Ventures. We’re also backed by founders like Wayee Chu of REACH Capital, Laura Spiekerman of Alloy, David Whelan of Town Hall Ventures and Michael Siebel of YC. Here’s what they have to say about our work:

What our founders
have to say

“At Symphonic, Sydney intentionally thinks about what is working in venture capital and what needs to change. She’s not focused on finding the two unicorns that will return a fund. Instead, she’s looking for broader, more sustainable success across an entire portfolio of companies. That’s because she believes this will drive the most impact and outsized returns in the long run.”
Thaddeus Fair
Managing Director
“What drew me to Symphonic was their background and experience. The fact that Shruti was a founder before felt unique. Many fund managers have worked at large banks or companies, but it’s different when you’ve worked at a startup and built a company yourself. They understand what it takes to build and scale and that’s part of what makes them great partners.”
William Cherniak
CEO & Founder
“Sydney was my first call when I started fundraising. As an ex-VC myself, I have a network of every VC in Silicon Valley, but she was the one I wanted. I want a real relationship with my investors, and Sydney is someone who jumps into the trenches with entrepreneurs.”
Kara Egan
Founder and CEO
