From PLG signup to paid customer, without ten tools.

A typical Tuesday in a Series-A SaaS

10am. Yusuf, founder of a 12-person developer tools company, opens CRM Solid. Yesterday brought 87 trial signups from a Hacker News post, way above the usual ~30/day.

The AI agent has already worked through every one. The contact view shows them sorted: 14 are flagged as "hot" (CTO at a Y Combinator portfolio company, asked about pricing in their first Telegram message, viewed the docs 12+ times). Of those 14, six already have Calendly slots booked with him this week. The AI qualified them on Slack, picked his open slots, and confirmed.

Another 51 are in active drip sequences, some on day 1 ("welcome, here is a 90-second video"), some on day 3 ("noticed you stopped at the auth step, common fix is X"), some on day 7 ("ready to move off your free tier?"). The remaining 22 are sub-ICP and getting a lighter touch on email only, with no founder time burned.

Yusuf spends 45 minutes reviewing the 14 hot threads, leaves voice-note replies on 4, then closes the laptop and goes to write code. That is the workflow.

What changes after two weeks

• Trial-to-paid lift of 2-4x in the first month. Most of the win comes from speed-to-first-reply going from 14 hours to 14 seconds.
• Founder hours back. Most PLG founders we work with reclaim 10-15 hours a week from triage. They write more code or ship more product. Either way: better company.
• Toolchain shrinks dramatically. Customer.io, Intercom, Zapier-glued Telegram bot, and a separate sales CRM all consolidate. Most startups save $400-$900/mo on subs.
• Lifecycle hand-offs stop falling through cracks. Free-user → paid → expansion → churn-risk is one continuous graph with the same data, instead of four disconnected tools passing JSON around.

Templates & playbooks included

The SaaS Startups playbook ships with PLG-tuned defaults:

• Day-0 welcome: email + optional Telegram founder DM, with a 90-second product walkthrough video
• Day-3 activation nudge: fires only if the user has not hit your "activated" event yet
• Day-7 trial halftime: pricing, social proof, and a one-click "book a demo" CTA
• Day-12 trial-ending: last-chance upgrade prompt with a 14-day extension offer for hot users
• Stalled-trial recovery: fires when a user who reached the "almost activated" state has been silent for 5 days
• Expansion drip: fires for paid users hitting 80% of seat / usage limit
• Churn-save sequence: fires on the "subscription-canceled" webhook from LemonSqueezy/Stripe

Integrations developers love

• Public REST API: push trial signups, in-app events, and identify calls with 5 lines of code. See /public-api for docs.
• Outbound webhooks: every CRM Solid event (new contact, stage change, AI scored, demo booked) can push to your stack via HMAC-signed webhook
• OpenAI / Anthropic / Gemini: bring your own model key, control which model powers your agents
• LemonSqueezy / WeePay: sync subscription state from your billing provider, trigger churn-save and dunning flows
• Calendly / Zoom / Google Meet: AI agent books on the right founder/CSM calendar with auto-generated meeting links
• Gmail / Outlook: IMAP+SMTP for transactional and lifecycle email
• GitHub: link issues to support conversations so dev teams see the customer impact of a bug

A 60-second API integration

Most SaaS startups wire CRM Solid into their app in under an hour. Here is the minimum viable trial-signup capture:

POST https://api.crmsolid.com/v1/contacts
Authorization: Bearer YOUR_API_KEY
Content-Type: application/json

{
  "email": "[email protected]",
  "name": "Jordan Park",
  "channel": "trial-signup",
  "traits": {
    "plan": "free",
    "company": "Acme Corp",
    "team_size": 14
  }
}

That single call creates the contact, triggers your "trial-signup" workflow, and (if configured) fires off the welcome email + AI Telegram DM within seconds. No SDK install, no plugins.
