How many dials does it take to book the first demo?

For a B2B product with a $500+ ACV, plan on 80–150 dials per booked demo for the first batch — connect rates of 12–18% × demo conversion of 7–10%. The number drops fast after dial 200 as your script tightens. If you're 300 dials in with zero demos, the problem is the list or the offer, not the dialing.

Should I use a dialer or call manually from my phone?

Use a dialer the moment you decide to do this seriously. Manual dialing caps you at ~12 connects per hour and you'll quit at call 50. A power dialer like Kolli does 60+/hour with auto-skip-voicemail, which is the difference between giving up and getting your first paid customer.

When should I hire an SDR instead of doing this myself?

When you can repeatably book demos yourself — same script, same list, same week — and only then. Hiring an SDR before that means hiring someone to fail at a problem you haven't solved. Most pre-seed founders should run the dialer themselves until they have 10 booked demos in a single week.

What's a realistic conversion from cold demo to paying customer?

8–15% from booked demo to paying customer in the first 90 days, for a B2B product priced under $5K/year. For high-ACV deals (>$50K) the rate is 5–8% but the cycle is longer. If your demo→paying conversion is below 5%, the demo itself is the problem — not the cold-call top of funnel.

How a pre-seed founder books the first 10 demos by phone

If you raised $500K–$2M and you're still pre-revenue, the next 14 days are the single highest-leverage block of work you'll do this year. Not building. Not raising more. Calling.

This is the playbook for getting from zero booked meetings to 10 booked demos, dialing your own list. No SDR, no agency, no marketing spend. Just you, a laptop, a headset, and a list of 600 prospects who fit your ICP.

TL;DR — 134 words

The first 10 demos at a pre-seed startup come from 600–1,000 dials over 14 days, made by the founder, on a list of strangers who match a one-line ICP. You will connect with 80–180 of them. You will get 8–14 demos booked. You will close 1–3.

The math only works if four things are tight: a list of fewer than 500 prospects per industry vertical, a 12-second opener that earns the next 30 seconds, a 30-second value pitch that names a specific pain you can prove, and a calendar link you send before you hang up. Skip any one of those and your dial-to-demo rate drops below 1%. Most founders quit at call 50. The ones who push to call 200 book their first paid customer.

Why founders, not SDRs

The reason you're calling — not an SDR — is that you are the only person who can answer the question "what does this product actually do." A pre-seed product is, by definition, not yet a product. It's a hypothesis with a Stripe link.

When the prospect asks "how is this different from Outreach?", an SDR reads a script. You explain the actual reason you started the company. That difference is worth 4× on the demo conversion rate at this stage. You don't get to outsource it.

You'll also be the only person willing to push past 50 calls without quitting, because every call is a data point about your own thesis. An SDR has nothing to learn from call 47. You have everything to learn.

The list — 600 prospects, 1 vertical, 1 line of ICP

The biggest mistake at this stage is a list that's too broad. You don't have time to talk to 12 personas in 12 verticals. Pick one vertical. One company stage. One title. Build a list of 600.

A useful default for a B2B SaaS product with a $1K–$10K ACV:

Vertical: the one you understand best (where you've worked, sold, or built).
Stage: Seed to Series B (15–150 employees). Smaller is too cheap, larger is too slow.
Title: the person who feels the pain. Usually a Head of X, not a VP — VPs delegate, Heads of X buy.

Tools that work for the list at $0:

LinkedIn Sales Navigator free trial — filter by industry, company size, title.
Apollo free tier — 50 free credits/month, enough for the first batch.
Manual research from competitors' customer logos.

Don't pay for a list. The act of building it teaches you your ICP.

The 12-second opener

Every founder writes a 90-second opener and gets hung up on. The hard rule: the prospect must want the next 12 seconds by the end of second 12.

What works:

"Hi [first name], it's Pavel from Kolli — I'll be quick. I help [specific company type] who are [specific problem]. Did I catch you at a bad time?"

Three things that opener does:

Names them by first name — they're more likely to listen than to a generic "Hi there."
Says it's quick — they don't think you're a 4-minute pitch.
Asks if it's a bad time — most cold-call training says don't ask. They're wrong. It earns 7–11% extra connect-to-conversation rate because it makes you sound human.

If they say "what's this about" — answer in one sentence, max. If they say "send me an email" — that's a soft no, push back once with "I'd be quicker on the phone — give me 30 seconds and if it doesn't fit I'll hang up."

The 30-second value pitch

After the opener, you have 30 seconds to answer one question: what specific pain do you solve, and why should I believe you can solve it.

Bad pitch:

"Kolli is the cold calling platform built for early-stage founders…"

Good pitch:

"Most pre-seed founders quit cold calling at call 50 because there's no copilot telling them what to say next. Kolli sits in your browser and gives you the right talking point for every objection — I built it because I needed it. We have 87 founders using it now, average is 240 dials per week per founder."

The good pitch:

Names the specific pain ("quit at call 50").
Names the specific mechanism ("copilot in your browser").
Earns trust with one number ("87 founders, 240 dials/week").

If you don't have the social proof number yet, replace it with: "I'm doing this from scratch — the first 10 founders to test it told me X."

The calendar link in real time

The single biggest gap I see in founder cold calls: the prospect says "OK send me something" and the founder says "I'll email you" and the email never gets sent that day.

The fix is mechanical. Have a Cal.com or Calendly link open in a tab. The moment they sound interested, say:

"Cool — I'm sending you a 25-minute slot for Tuesday at 10. Do you have your phone? You'll see it pop up in 5 seconds."

If they have the link in their hand before you hang up, the show rate is 80%. If you "follow up by email tomorrow," the show rate is 35%.

This is the single mechanic that doubles your dial-to-demo rate.

Dial volume — what 600 dials in 14 days actually looks like

The math:

600 dials ÷ 14 days = ~43 dials/day.
2 hours of focused dialing at 25 dials/hour (with a power dialer) = 50 dials.
One 2-hour block per day, 5 days/week.

The two-hour block matters. Cold calling has a warm-up period of about 12 calls before your voice settles and your objection responses get sharp. A two-hour block gets you 38 calls past warm-up. Six 20-minute blocks gets you zero calls past warm-up.

Block your calendar. Same time every day. Headset on, laptop closed, dialer up.

What goes wrong (and what to do about it)

The four common failure modes at the pre-seed stage and the fix for each:

1. Quit at call 50. The voice in your head says "this isn't working." Push to call 200. The whole skill curve is between call 50 and call 200. If you've actually made 200 calls and you have zero demos booked, then you have a problem worth investigating.

2. List is too broad. You're calling 6 different titles across 4 verticals because you "want to learn." You're learning nothing because every conversation is a different conversation. Pick one slice and exhaust it.

3. No copilot. You forget the answer to "we already use [competitor]" and you fumble. Have a one-pager with your top 5 objections and the three-sentence response to each, taped to your monitor. (Or use a tool that surfaces it on screen — but a piece of paper works.)

4. No same-day calendar invite. Solved above. Have the link open. Send it before you hang up.

The 14-day schedule

For founders who like a concrete week-by-week:

Week 1:

Day 1–2: build the 600-prospect list, write the opener and 30-sec pitch.
Day 3: warm up — 50 dials, expect them to be rough. Listen to your own recordings.
Day 4–5: 50 dials/day, refine opener based on what's working.
Day 6–7: review 5 best-performing call recordings, adjust pitch.

Week 2:

Day 8–12: 50 dials/day, this is where the demo bookings start landing.
Day 13: dedicated demo day — run the meetings you booked.
Day 14: review. How many demos booked. How many showed up. How many converted. What's the iteration for the next 600-prospect list.

If at the end of week 2 you have 10 booked demos and 1 paying customer, you've validated cold calling as a channel for your product. Expand the list to 1,500 and run it back.

If at the end of week 2 you have fewer than 3 booked demos, the problem is one of three things: list, offer, opener. Not effort. Re-read this post. The fixes are in the four numbered failure modes above.

What you'll know after 600 dials

By dial 600 you will know — concretely, not by intuition — three things you cannot learn any other way:

The exact phrase your prospect uses for their pain (not the phrase you assumed they used).
The first 5 objections they raise in order of frequency.
The specific combination of vertical + title + company size where conversations actually go anywhere.

That's the first version of your ICP. It's the document every other GTM hire is going to read. You can only write it from 600 dials. Not from 60. Not from a Discovery interview. From 600 dials.

Then you hire the SDR. Then you write the playbook. Then you scale.

But not before. Pick up the phone.
