I run about 20 domains across my products, and email kept failing me in the most expensive way possible: silently. Campaigns showed delivered while landing in spam. We switched email providers and forgot one DNS record, reply rates collapsed, and we spent weeks blaming the copy. A tool we d stopped using was still authorized to send as one of our domains.
None of these show up as errors. You find them months later, after they ve cost you real money.
The existing DMARC tools are built for security teams and read like RFCs, so I built HealthCheck Email(healthcheckemail.com) for marketers and founders instead:
Enter a domain and get an A+ to F email health grade in seconds, covering DMARC, SPF, DKIM, MX, blacklists, and TLS
It parses the reports mailbox providers send about your domain, so you see every service actually sending as you, with names like Google Workspace and Klaviyo instead of IP addresses
A guided path from DMARC p=none to reject without blocking your own legitimate mail
Daily re-checks with alerts to email, Slack, or webhook the moment a record changes
Most SaaS companies make interested buyers wait days for a demo slot. By the time the call happens, half the momentum is gone.
We built @Naoma an AI video agent that runs a live, personalized product demo instantly, right on your website. No scheduling. No waiting room. No "let me loop in a sales engineer."
It walks through your product in a real browser session, answers questions on the spot, qualifies the lead, and routes them to CRM, a booked call, or checkout depending on where they are in the funnel.
In early pilots, we're seeing visitor-to-demo conversion in the 6 15% range. Clients include Yesim, UXPressia, Mellow, and others.
Viktorly is a calm support app for panic and overwhelming anxiety.
I m building it because I wanted something that helps in the exact moment panic starts, not just general wellness advice or long explanations.
The app combines voice-led guidance, grounding practices, journaling, and community support so people can get immediate help when everything feels like too much.
I m sharing it here because I m still shaping it with real user feedback, and I d love to connect with other founders building in mental health, support, or voice-led products.
I'm Astik, a solo full-stack dev, and I built ReactGrind a LeetCode-style platform, but instead of reversing linked lists, you're solving real React problems: building components, managing state, fixing broken hooks, debugging re-render issues, etc.
Why I built this: I kept noticing a gap tons of platforms train you for algorithmic interviews, but almost none train you for the actual React problems you'll face in interviews and on the job. So I built ReactGrind from scratch (A Sandpack, running live in-browser) to fix that.
