Computer science crosswords for anyone curious about computer science.

Every plan comes with built-in access to a vast contact graph. Describe your ideal customer and the agent finds, verifies, and enriches the perfect matches — then reaches them. Bring your own CRM and lists too — persist.chat works alongside what you already have. No campaign builders to wrestle with. You talk, the agent works. "Founders who raised this quarter." "Buyers looking in 94110 under $1M." Plain English — that's the whole interface. It pulls matches from 200M+ contacts, enriches their details, and drafts a personalized message for every single person. Multi-channel sequences with smart timing. It handles replies, pauses on a response, and books meetings to your calendar. Personalized messages on a cadence you set — 1 day, 3 days, 7 days, or your own — switching channels to stay fresh. The moment they respond, it stops. Personalized opener referencing what they care about. A short nudge — only if they haven't replied. A new angle — proof, a case study, or an option. A different channel keeps you top of mind. Email opener, LinkedIn warm-up, a direct text, a DM on X — orchestrated as one sequence, paced to stay deliverable. Warmed mailboxes, personalized at scale, with open and reply tracking. The highest-response channel, used sparingly for the direct ask. Connect and warm up before the pitch — build familiarity that converts. Follow and DM people based on what they post — reach them while it's relevant. This is the real persist.chat app, running live. Talk to the agent, build a sequence, browse the inbox — no signup needed. Tip: try a starter prompt like “Find Mission buyers under $1M” — the agent will find leads and build the sequence. Every message references the person — their company, role, listing, or a signal it found about them. 1-day, 3-day, 7-day — branch on opens and replies. Or just let the agent decide. Every reply across every channel in one place — the agent drafts your response and stops the sequence. See replies, meetings, and attributed pipeline by channel — and what the agent should double down on. Sync a CRM, drop a messy spreadsheet, or let the agent prospect net-new. All roads lead to outreach. Review and approve before anything sends, or let it run autonomously once you trust it. We're onboarding early-access teams in batches. Drop your email and we'll send your invite — with the full contact graph included.
