A free power dialer for startups doing founder-led outbound

Last updated September 3, 2026

This is for the founder or first sales hire at a pre-seed or seed company who has to make the calls personally for the next few months. The "dialers for startups" pages are vendor tiers with a startup label on them. This one covers what is actually free, the exact line where it stops, the Twilio bill at founder volumes, a 30-day plan, what to log so the first hire inherits data, and the honest point at which you should pay for Orum or Nooks instead. Solo operators with no plan to hire have their own page: a power dialer for solo founders. This page assumes a team is forming.

The short answer

Do not buy a $99-a-seat dialer before product-market fit. Run founder-led outbound on a free power dialer connected to your own Twilio account: $0 software for one person up to 500 leads and 500 calls a month, about $9 a month to Twilio at 50 dials a day. When the first hire lands, or you cross 500 calls, Pro is $29 a month for 3 seats. Graduate to a parallel dialer when you have two full-time SDRs, a cold list, and a pitch that already converts; not before.

Why the $99 seat is the wrong first purchase

Close (~$99–139/user/mo), JustCall (~$19–89/user/mo (annual)) and Kixie (~$35–65/user/mo) are good tools for a sales team. A startup before product-market fit is not a sales team; it is one person testing whether anyone will take a meeting. The features that justify those seats, manager dashboards, multi-rep reporting, coaching queues, forecasting, have no user for the first ninety days. The annual commitment that most of the headline prices require locks in a headcount you have not hired. And the data you generate in that window fits in one CSV, so nothing about starting cheap is a migration risk.

The money matters less than the attention. A founder who spends a Saturday configuring a sales-engagement suite has spent a Saturday not calling. The bar for the first tool is: import a list, dial it in order, record what happened, remind me to call back. Everything else can wait until there is a second person to use it.

What the free plan includes, and the exact point it stops

Free is one person, 500 leads in the account, 500 calls in a calendar month, forever, no card. Included: browser calling on your own Twilio (no softphone, no desk phone), power-dial auto-advance, CSV import with automatic column mapping where only the phone column is required, tags, dispositions, custom fields, callback reminders, tasks, a pipeline, a DNC suppression list, and local-presence rotation across the numbers you own. Not included: recordings and transcripts in-app, AI summaries and script scoring, the 2-to-4-line parallel dialer, email sequences, SMS, and the API. Those are Pro, $29 a month for a 3-seat pack, never per user.

The 500-call line is the one you will hit. At 20 dials a day it never arrives (420 dials in 21 working days). At 50 a day you cross it around the tenth working day. That is deliberate: the free plan is sized for a founder who dials part-time, and a founder who is dialing 50 a day has a business worth $29 a month.

The bill at each stage of a forming team

Twilio bills connected time in whole minutes: unanswered rings are free, a voicemail greeting bills one minute, a conversation bills its length rounded up. The table assumes a quarter of dials reach voicemail, a tenth reach a person, three minutes when they do, one local number per seat, and 21 working days. The last column is the same headcount on a $99-a-user seat, the low end of the Close range, before its minutes.

Stage	Dials / mo	Software	Twilio	Total / mo	$99 seats
Founder, evenings and mornings1 seat, 20 dials a day each	420	$0 (free plan)	$4	$4	$99+
Founder, a daily dial block1 seat, 50 dials a day each	1,050	$29	$9	$38	$99+
Founder + first sales hire2 seats, 50 dials a day each	2,100	$29	$19	$48	$198+
Founder + two reps3 seats, 50 dials a day each	3,150	$29	$28	$57	$297+

Software is $29 for one to 3 seats; the founder-plus-two row costs the same pack as the founder alone. Twilio is ~$0.014/min plus ~$1.15/month per number, list rates from Twilio's US voice pricing page, September 2026. If you truly never want a Twilio account, a $49/month managed line with 1,500 minutes exists, but for a founder the Twilio route is cheaper at every row above and takes ten minutes. More on the per-SKU detail in Twilio cold calling cost.

A 30-day founder-led outbound plan

Four weeks, one list at a time, 50 dials a day by week two. The point is not the dials; it is that by day 30 you know which segment answers and which opener survives contact, and it is written down.

Week 1: list and setup

Pull 200 accounts that match one ICP hypothesis, not three. One CSV, one phone column, one segment tag.
Open Twilio, add a card, buy one local number (~$1.15/month), paste SID and token into the dialer. About ten minutes.
Write a 20-second opener and a five-line objection sheet. Version them: v1.
Dial 30 a day for three days from the list. Log the five fields. Do not change the script yet.

Week 2: volume

Move to 50 dials a day in one uninterrupted block. Callbacks first, then new dials.
Every promised callback gets a reminder in the dialer, not a sticky note.
Friday: read the objection column. If one objection is more than a third of conversations, rewrite the opener to pre-empt it. Version it: v2.

Week 3: second segment

Add 200 accounts from a second ICP hypothesis with its own tag. Keep dialing the first.
Buy a second number and let the dialer rotate; you are now near the pattern one number should not carry alone.
Track conversations-to-meetings by segment and script version. Small numbers, but the direction shows.

Week 4: decide

You will have made about 1,050 dials and passed the free plan's 500-call line in week two; Pro at $29 covers it and the next two people.
Kill the weaker segment. Export the log; that CSV plus the recordings is the onboarding pack for the first hire.
If meetings per 100 dials is holding above two on the surviving segment, hire. If not, the problem is the list or the pitch, and no dialer fixes either.

Scripts and the mechanics of a 100-dial day are covered in cold call script templates and how to make 100 cold calls a day.

What to log so the first hire inherits data, not anecdotes

The first sales hire at most startups inherits a founder's memory and a spreadsheet with a Notes column. Neither survives the handover. Five fields on every dial fix that, and all five are free on any tool worth using:

Disposition: no answer, voicemail, gatekeeper, conversation, meeting. One of five, every time.
Objection: three words. "Using competitor", "no budget", "not the buyer". This column is the product roadmap.
Callback: a date and time, set as a reminder, or the promise is fiction.
Script version: v1, v2, v3. Without it you cannot tell whether the segment improved or the opener did.
Source and segment: which list, which ICP hypothesis. Meetings per 100 dials by segment is the only number a first hire needs on day one.

Recordings are the sixth thing and the best training material there is; they are Pro on most tools, ours included, and stored in your own Twilio so they leave with you. Export the log as CSV monthly regardless. The hire should receive a file, not a story. See a free CRM with a power dialer for how the pipeline side fits.

When to graduate to Orum or Nooks

Parallel dialers ring several numbers at once and connect the rep to whoever answers first. Orum (~$250+/user/mo) and Nooks (~$100–200/user/mo) are the two funded SDR teams buy, both on annual contracts. They are excellent at one job: pushing a full-time rep through a large, cold list where under a tenth of dials connect. Graduate when all three of these are true.

Two or more people whose entire job is dialing. A founder who dials two hours a day does not earn back a $250 seat.
A list large and cold enough that connect rates sit under 10%. On warm lists, parallel dialing produces the answered-then-abandoned call that burns the prospect and the number.
A pitch that already converts on a power dialer. Multiplying dials multiplies whatever the pitch does; if it does nothing, you paid to do nothing faster.

Until then, a single-line power dialer, or the 2-to-4-line parallel mode on Pro, covers 50 to 100 dials a day per person. The trade-offs, including the legal edges in some markets, are in parallel dialer vs power dialer and are parallel dialers legal. When you do move, your numbers, recordings and list are in your own Twilio account and a CSV, so the move is an afternoon.

Free for the founder, $29 for the first three

500 leads and 500 calls a month at $0 on your own Twilio, no card. When the first hire starts, one $29 pack covers 3 seats, and the data is already there.

Start dialing free

Questions people actually ask

Is there a genuinely free power dialer for a startup?

Yes, with one condition: the calls run on your own Twilio account, which bills you directly at about ~$0.014/min for connected time and ~$1.15/month per number. DialSheet's free plan is one person, up to 500 leads and 500 calls a month, with the power dialer, CSV import, dispositions, callbacks and pipeline included, no card and no expiry. The other free options we found are trials (JustCall 14 days, Kixie 7 days), capped mobile apps (Calley, 25 calls a day through your SIM), or vendor free tiers with a few minutes a month. We could not find another free power dialer that runs on your own Twilio account; if one exists we would like to list it.

Should a startup buy a $100-per-user sales dialer before product-market fit?

Usually not, for three reasons that have nothing to do with the money. Before product-market fit the script changes weekly, the ICP changes monthly, and the person calling is the founder, so the features a $99-a-seat tool sells (multi-rep reporting, manager coaching, forecasting) have no user yet. Second, annual contracts, which most of those tiers require for the headline price, lock in a headcount you do not have. Third, the data you produce in the first ninety days is small enough that migrating it later is a CSV export. Spend the seat money on list quality instead; a bad list wastes far more founder hours than a basic dialer ever will.

What does the free plan include, and exactly where does it stop?

Included: browser calling on your own Twilio, power-dial auto-advance, CSV import with column mapping, tags, dispositions, custom fields, callback reminders, tasks, a pipeline, a DNC suppression list, and local-presence rotation across the numbers you own. It stops at three hard lines: 1 seat, 500 leads in the account, and 500 calls in a calendar month, after which the dialer waits for the counter to reset. Recordings, transcripts and AI summaries in-app, the parallel dialer, sequences, SMS and API access are Pro. Pro is $29 a month for a pack of 3 seats, so the first hire and the second one cost nothing extra once you are on it.

How much will Twilio cost a founder making 50 cold calls a day?

About $9 a month. Twilio bills whole minutes of connected time only, so the 50 dials break down as roughly 32 unanswered rings that cost nothing, 12 voicemail greetings at one billed minute each, and 5 conversations at three minutes: around 28 billed minutes a day, 588 a month, at ~$0.014/min plus one local number at ~$1.15/month. Add a second number for rotation and it is a dollar more. Twilio's trial credit does not cover this because trial accounts can only call verified numbers; you add a card and it bills the actual usage. Recording storage, if you turn it on, is a fraction of a cent a minute on top.

When should a startup graduate to a parallel dialer like Orum or Nooks?

When three things are true at once: you have two or more full-time SDRs whose only job is dialing, the list is large and cold enough that connect rates sit under a tenth, and someone has already proved the pitch converts. Orum lists at ~$250+/user/mo and Nooks at ~$100–200/user/mo, both annual, so the bet is that each rep's extra conversations per hour pay for a seat that costs more than most founders' entire tooling. Before that point a power dialer at one line, or a two-to-four-line parallel mode, gets a founder through 50 to 100 dials a day without the answer-and-hang-up problem that multi-line dialing creates on warm lists. Parallel dialing also has legal edges in some markets; see our page on whether parallel dialers are legal.

What should a founder log so the first sales hire inherits something useful?

Five fields, on every dial, without exception: the disposition (no answer, voicemail, gatekeeper, conversation, meeting), the objection in three words if there was one, the callback date and time if one was promised, the script version you used, and the lead source. That is enough for the hire to see which segment answers, which objection kills the call, which source produced the meetings, and which version of the opener is current. Recordings are the sixth thing and the most valuable one for training, but they are a Pro feature on most tools, ours included; the five fields are free everywhere and most founders skip them anyway.
