who are you?
she's climbing toward the summit.
you're the one holding the rope. she's climbing toward the summit.
he's the one holding the rope.
that's not a supporting role — the belayer is what makes the summit possible. you just needed a guide. that's not a supporting role — the belayer is what makes the summit possible. he just needed a guide.
belayer
the person who secures the climber by managing the rope. "i've got you."
every pregnancy app is built for her. what about you? he wants to help. he just doesn't know how.
you want to help. you just don't know where to start. he's not going to download a pink pregnancy app. and he shouldn't have to.
nobody prepared you for this. so we built the guide that does. there's finally an app that meets him where he is. and it's actually good.
a trail guide. an ai coach. a toolkit built for you.
the backbone
92 weeks. every one mapped.
know exactly what's happening this week — your baby, your partner, what you can actually do. not a textbook. a trail guide. every week, he'll know exactly what's happening — your baby, how you're feeling, and what he can actually do to help.
free for everyone. always.
your baby this week
what's growing, what's changing, and all the weird-cool stuff happening.
how she's feeling how you're feeling
the real stuff — symptoms, emotions, what she might not say out loud. real talk about what's happening in your body and mind this week.
what you can do what he can do
actual moves. not "be supportive" — specific things that actually help this week. specific actions, not generic advice. things that actually help this week.
the ranger
your trail coach for the hard questions. a trail coach for the questions he's afraid to ask.
not generic tips — real conversations about what's happening right now, in your week, with your situation. every question he's embarrassed to google, every scenario he hasn't prepared for — answered by an AI that actually knows his week.
the ranger
ai trail coach · available 24/7
reads your birth plan answers and checks in after the appointments that matter
notices when your mood dips three days in a row — and reaches out before you ask
already knows your birth plan, your values, and your postpartum setup — so every conversation starts from where you actually are
some questions need a campfire, not a search engine.
your conversations are private.

it takes 10 seconds
campfire circle
an anonymous circle of partners on the same trail. an anonymous circle of partners — all figuring it out together.
no profiles. no judgement. just honest conversations from people who get it. no profiles. no judgement. a space where partners actually talk about what they're going through.
overheard at the campfire
"I thought I was the only one who felt guilty about being tired."
"knowing someone else was awake at 3am made the whole difference."
"I finally asked the dumb question. turns out it wasn't dumb."
campfire talks
pregnancy can pull you apart.
these bring you back together. pregnancy can pull you apart.
these help him bring you back together.
guided prompts for the conversations you want to have but don't know how to start. guided prompts that help him say the things he wants to say but doesn't know how.

"what did your parents get right that you want to repeat?"
week 16
"what does a good first week home look like to you?"
week 34
52 guided conversations. one for every week.
the descent
most apps quit at delivery.
the hardest part is just beginning.
paternal depression rates
8%
months 1-3
26%
months 3-6
paternal depression triples — right when leave ends and support disappears.
the 3-6 month mark is the danger zone. sleep regression hits. friends stop checking in. every other app has already quit. belay stays with you for 52 weeks after birth — because showing up doesn't stop at the summit.

why i built this the partner who built this
I built Belay because I was that partner. Sitting in the OB waiting room, scrolling Reddit at 2am, asking "what can I do?" and seeing her eyes glaze over. Every app was built for her. Every book assumed I'd figure it out. Nobody told me what was coming — or how to show up when it did. So I built the guide I wish I'd had.
