About
Built for founders who cannot afford to lose a reply.
PortKnot · Hanoi, Vietnam · Updated 31 October 2026
PortKnot is an outbound workspace for solo founders and very small teams running 2–5 B2B products. It keeps each product's leads, campaigns, templates, approvals, sends, and replies in their own lane — without automating LinkedIn or hiding a black-box sender.
What we believe
- A reply is revenue. It should stop the sequence, reach a human, and carry the product and campaign context with it.
- Humans approve outbound. AI can draft and classify; it should not impersonate you or send without review.
- Delivery is part of the product. Bounces and complaints must suppress the lead and stop future sends, not just update a report.
- Fewer products, better focus. A founder running several products needs separation and a weekly wedge, not another giant dashboard.
What PortKnot is not
PortKnot is not a contact database, a LinkedIn bot, a mass-mail blaster, or an AI SDR that talks to prospects without you. It does not sell lists, scrape private data, or guarantee deliverability.
How the product is organized
Each product has its own ICP, campaigns, templates, approvals, and replies. Email can send through your own Resend account or through platform-managed sending. Every email is approved before it can send. A reply stops the matching sequence and opens in Reply Rescue. LinkedIn work is always a manual task.
