Leads go cold when nobody follows up. This calculator turns 'I should follow up later' into an annual dollar number.

The four reasons leads go cold
1. The "I'll write it up later" tax. A 90-minute meeting ends at 4pm. By the time you sit down to enter notes at 7pm, the next-step you agreed to has gone fuzzy. Within 48 hours half the context is gone. The lead is now a maybe.
2. The pipeline-review blind spot. Most CRMs put leads in a list ordered by stage or recency-of-creation. The lead that needs you to act first is buried under leads that look more recent. Without an "overdue followup" surface, busy weeks bury good leads.
3. Heads-down delivery stretches. The classic indie-operator pattern: 2 weeks on client work, surface for air, realize 6 conversations have gone silent. By then the prospect has already decided you are not interested.
4. Calendar fragmentation. Followup tasks live in todo apps, in calendar reminders, in email drafts, in nothing at all. Without a single home, half disappear.
Yuzen is built around the inverse: voice entry to capture before the context fades, an "overdue" surface as the home screen, activity tracking that doesn't require a setup call.
Frequently asked questions
What is pipeline leak?
Pipeline leak is the revenue you would have closed if every promising lead got a timely follow-up. Most leak is invisible because the lead never says 'I went with a competitor' - they just go silent. The cost shows up in your bank account, not in your CRM.
How fast does a lead actually go cold?
Harvard Business Review's classic study found that contacting a web-form lead within 5 minutes makes you 100x more likely to qualify them than contacting them within 30 minutes. After 24 hours, 80% of inbound leads are effectively gone. The longer the silence, the more it costs.
Is a 30% cold rate really realistic?
For solo operators juggling delivery and sales? Yes, often higher. The classic pattern is heads-down on a paid project for 2 weeks, then realizing 6 promising conversations went silent during that stretch. Multiply that by 5 busy stretches per year.
How does Yuzen reduce pipeline leak?
Two ways. First, Yuzen surfaces overdue leads on the home screen so they cannot disappear into a dashboard you forget to open. Second, voice entry lets you capture next-step notes 30 seconds after the call instead of waiting until evening - which is when most followup intentions die.
What counts as a 'lead' in this calculator?
Any conversation with a real person who showed interest. Inbound form fills, referral introductions, networking exchanges, conference cards, replies to outbound. Excludes pure cold lists where there has been zero two-way engagement.
