MirrorTab is a seed-stage cybersecurity startup building a new layer in the security stack — one that protects data where many existing tools stop: the browser.
For too long, companies have normalized their inability to secure data once it reaches the customer’s browser. As more of our lives and work move online, this gap has become a major vulnerability — enabling phishing, impersonation, and other forms of digital data exfiltration that traditional security tools don’t fully address.
MirrorTab is changing that. By safeguarding data at the browser layer, we’re helping make the internet a safer place to do business.
We raised our seed round in February 2025 and are backed by Valley Capital Partners, Alumni Ventures, and Google Ventures.
Our first DTC product, Haven (starthaven.com), is a secure desktop app designed to help people bank online with confidence. Haven recently soft-launched, and we’re now shifting focus from building the product to growing its adoption.
We’re looking for a Generalist Growth Marketer to become our first marketing hire and help define how Haven shows up in the world.
This is an early-stage role with real ownership. You won’t be maintaining a mature marketing machine - you’ll help build it. You’ll work closely with the CEO and leadership team to clarify messaging, grow awareness, and run early experiments across paid, organic, and product-led channels.
If you’re excited by early-stage products, learning fast, and having a meaningful impact, this role is for you.
Your core goal is simple: help more people discover Haven, understand it, and try it.
You’ll spend most of your time on:
Over time, you may also experiment with LinkedIn, email, and community — but the focus will be on doing a few things well, not everything at once.
You’ll have a lot of autonomy and trust from day one.
