Private Social Media With

Swoosh mailbox: /dev/mailbox
Closed Alpha
My100 is currently in closed alpha testing. New accounts are invite-only — ask someone already on My100 for an invite link.
We're actively seeking feedback on features, bugs, and ideas.
Private social media turns posting into an act of connection. Responses are between you and the person responding.
Without an audience, conversations change. There's no need to explain yourself to strangers or perform for a crowd.
One post can lead to many conversations without becoming a group chat or public event. Each interaction stands on its own, shaped by the relationship behind it.
My100 exists to help real people stay connected without being exploited for profit by moneyed interests.
Social media should make relationships stronger, and stronger relationships come from smaller circles.
Public social media platforms chose for advertisers and data brokers to be their real customers, and the users pay the price.
Everything on My100 has a preset lifespan. Posts and conversations are designed to expire and are permanently deleted.
No discovery, no amplification, no engagement driven algorithms, no hidden audience. No public layers beneath the surface.
My100 doesn't mine your posts, train AI models on them, or sell access to them. Your data is not our business.
Free During Alpha & Beta
My100 is completely free while in alpha and beta testing. When we launch, alpha and beta testers will have their accounts sponsored at the Host level for a period as a thank-you for early support.
Guests can send direct messages and react to posts with emoji. They can't create posts or upload images.
Members can create posts, share images, and react to posts from their My100. This is the full experience.
Hosts can sponsor connected guests, elevating them to full member status.
Because human relationships have natural limits. Anthropologist Robin Dunbar's research shows that people can only maintain meaningful social relationships with a finite number of individuals. My100 is designed around that reality, not around infinite growth.
Dunbar's number is a theory that humans can meaningfully maintain about 100–150 social relationships at a time. My100 uses a lower bound of that range to keep connections personal, contextual, and real.
Because unlimited connections turn relationships into audiences. By capping connections at 100, My100 stays focused on people you actually know, not people you're trying to reach.
Yes. Everything on My100 happens inside mutual connections. There are no public posts, no discovery feeds, and no hidden audiences.
Only people who are in your My100 and have added you back. If the connection isn't mutual, the content doesn't exist for them.
Yes. Everything expires and is permanently deleted based on the time window you choose. Content isn't archived, hidden, or reused later.
No. We don't harvest it, mine it, sell it, or train models on it. Your data exists only to support your relationships.
No. Your content is never used for algorithm training, internal or external. Period.
No. Your feed is chronological and only contains posts from people you're connected to. What happened is what you see.
No. There's no resharing, quoting, or public amplification. Posts live and die inside your circle.
No. Conversations happen as private, person-to-person threads tied to a post. They don't turn into public comment sections.
Reactions are lightweight signals that only you and the poster can see. Comments open a private conversation with the person who shared the post.
Because relationships aren't competitions. Private reactions remove performance pressure and keep interactions honest.
Your account and all of its data are permanently deleted. Posts, messages, reactions, and connections are fully removed and are not retained or reused.
We're growing slowly and intentionally during alpha. Invite-only lets us focus on quality, gather feedback from real users, and build something worth opening up. Each user can invite a limited number of people to help keep the community manageable.
Because when users are the customer, the platform stays aligned with their interests. My100 doesn't rely on advertising or data extraction to survive. During alpha and beta, everything is free. When we launch, pricing will be straightforward and affordable.
Hosts can sponsor memberships at a steep discount for people they care about. It lets one person cover the cost so others can participate freely.
Yes. Once pricing goes live, you'll be able to move between Guest, Member, and Host at any time. During alpha and beta, all features are free.
No. My100 isn’t meant to replace everything you use. It’s meant to give you one place where sharing stays personal, private, and grounded in real relationships.
All of the above, as long as the connections are mutual and personal. My100 works best when people actually know each other.
That connection ends, and any shared data between you is deleted. Nothing remains visible, accessible, or stored.
