Startup Idea #002: CallSifter: Turn Every Client Call Into Action (and Revenue)
AI for Client Call Summaries + Lead Scoring → $3M ARR Potential Opportunity
Let’s be honest: most client calls are just expensive small talk.
You show up, smile through vague interest, scribble some notes you’ll never read again — and forget whether “Jessica from the sauna company” was a hot lead or just sweaty.
Welcome to solopreneur hell.
If you’re a coach, freelancer, parentpreneur, or boutique agency founder, you already know the pain.
You’re spending hours on Zoom, then another hour trying to remember who said what, who might pay, and who just wanted to “circle back.”
Meanwhile, your toddler’s screaming, your coffee’s cold, and your CRM hasn’t been touched since the Obama administration.
That’s where this week’s startup idea comes in.
CallSifter is an AI assistant that joins your calls, transcribes them, pulls out action items, and ranks the leads based on actual buying signals.
You don’t need to take notes. You don’t need to guess who to follow up with. You don’t even need to remember who “Tony from Tulsa” is.
And here’s the kicker: it’s a potential $3M ARR business, built with off-the-shelf AI, a simple UX, and a clear wedge.
No giant team. No bloated CRM. Just one sharp tool that turns conversations into conversions.
If you’re tired of forgetting leads, losing deals, or rewriting the same follow-up email 17 times, this one’s for you.
Let’s break it down. Problem. Product. Pricing. Proof.
And why you might be the one to run with it.
🟥 Problem
Manual call notes are error-prone, slow, and often skipped
Most CRMs are overkill or ignored after Day 3
High-value leads slip through cracks with no follow-up
Sales calls don’t translate into action—no next steps, no reminders
AI tools exist but aren’t tailored for indie pros or parent-run shops
✅ Solution
CallSifter auto-records, transcribes, summarizes, and ranks leads from your Zoom/Meet calls.
Features:
🎙️ Automatic call summaries with tone and intent detection
⭐ Lead scoring based on urgency, budget, and buying signals
🧠 AI-generated next steps, reminders, and email follow-ups
📥 CRM-light dashboard (or push to your actual CRM)
🔁 Auto-tag recurring clients or referrals
➡️ Designed for solopreneurs, coaches, boutique agencies, and consultants
💸 Business Model
$19/mo starter → 10 calls/month
$49/mo pro → Unlimited calls, CRM sync, AI follow-ups

🥊 Competitive Landscape
Otter.ai: Great summaries, but no lead scoring
