The founder

Built by a real
cruiser.

I'm Shriya — 18 years old, based in New Jersey, and genuinely obsessed with cruising. I've sailed Royal Caribbean's Symphony of the Seas and Norwegian Luna, and I've spent the last year building a TikTok following of over 4 million views talking about cruise planning.

Seastart exists because cruise planning is genuinely confusing. There are so many lines, so many ships, and so much advice online from people who have never actually set foot on a ship. I got tired of it and built something better.

Everything in this app is first-hand. The Cruise Matcher uses real knowledge of what each line does well. The packing list includes things I wish someone had told me — like bringing magnetic hooks because your cabin walls are metal. The Compare tool shows you what actually matters.
