AppealSealMeet the Team Behind Appeal Seal
We're Philipp and Marissa — two homeowners who discovered just how broken property tax assessments can be. After appealing our own taxes and getting thousands back each year, we realized most people don't even know this is an option. So we built Appeal Seal to make it fast, fair, and accessible for everyone.
👨💻 Philipp — Two-Time Founder and Builder Behind Appeal Seal
Philipp is a two-time founder and the brains behind Appeal Seal. After his recent exit, he decided to put his software engineering skills—and curiosity for AI—to work. He's validated hundreds of comps, trained the system to think like an assessor, and made it smarter (and faster) than anything else out there. Thanks to AI, Appeal Seal now finds the best comps your county is most likely to approve, giving you the strongest shot at a "yes."
👩 Marissa — Educator and Believer
Marissa is a marketing maven and the voice behind Appeal Seal, the one shouting (politely) that there's free money out there for you. Many of us are overpaying our property taxes, and she's on a mission to give every homeowner the power to stick it to the tax office, respectfully, of course. She's passionate about helping people understand this short window of opportunity before interest rates and property values shift again.
🏡 Why We Built It
We could have spent months perfecting the design. But the deadline is November 30th — and we didn't want you to miss out. So we focused on what matters most: accurate reports, clear instructions, and a process that actually works.
