They told me my AI-powered sourdough startup wouldn’t work. They were right, but now I have VC funding.

Success Stories

***

Breathify.ai
Tagline“Breathe smarter, not harder.”

With Breathify.ai, we’re finally disrupting the outdated monopoly of oxygen. Our proprietary “Air-as-a-Service” (AaaS) platform uses advanced AI algorithms to personalize your breathing experience. Think optimized oxygen-to-carbon-dioxide ratios, allergen detection, and even mood-enhancing aromatics, all delivered in real time. You’re not just breathing—you’re thriving.

Seed Round Valuation: $55M

Purrspective
Tagline: “Helping your cat unpack nine lives of trauma”

Purrspective is the world’s first therapist chatbot tailored exclusively for cats. Powered by our proprietary MeowGPT-9 engine, it deciphers your cat’s vocalizations, body language, and passive-aggressive purring to provide targeted mental health support. Whether your feline is suffering from post-vet stress disorder, abandonment issues from the time you went on vacation for three days, or just existential dread from staring at the void between the couch cushions, Purrspective is here to listen.

With guided mindfulness exercises like “Breathe Through the Fur” and interactive sessions including “Why the Red Dot Is Not Your Fault,” we empower cats to heal, one paw at a time.

Pre-Seed Round Valuation: $25M
VC reaction: General Catalyst enthusiastically dubbed it “a headspace for headbutts,” while Andreessen Horowitz’s cat-loving partner claimed, “My tabby immediately stopped knocking over wine glasses.”

GhostMode

Tagline: “Be there by not being there.”

GhostMode automatically disables your social media apps during peak addiction hours (like midnight to 3 AM), but here’s the genius part: it posts cryptic, mysterious status updates on your behalf to make everyone think you’re too cool to be online. Examples include:

  • “Can’t talk. Something big is coming.”
  • “Don’t DM me. You wouldn’t get it.”

When you finally log back on, you’re greeted with a summary of everything you missed, distilled into a single headline: “Nothing important happened. Congrats.”

Pre-Seed Valuation: $45M
VC reaction: “It’s the FOMO antidote we’ve been waiting for. I’ll invest $2M if you make the fake statuses sound more unhinged. Gen Z thrives on chaos.”
