Cut the SaaS

Turn site visitors into booked calls on autopilot

Solo or seed-stage founder whose landing page gets traffic but the 'contact us' inbox is where leads go to die.

Wired & tested by Sameer + Ankit

Free · the verdict

You don't need a $1k/mo 'revenue platform' to book inbound calls. A free booking link, a free qualifier form, and one free automation runner stitched together will out-convert most paid stacks, because it replies in seconds, not days. Pay for exactly one thing (a domain to send 'from'), wire it in an afternoon, and let it run.

The stack

Cal.com
Tally
Make
HubSpot CRM
Resend
RB2B
  • Cal.comThe booking link. Self-serve 'pick a time' that writes straight to your calendar with a video link attached.

    $ Free forever for individuals, no cap on event types (unlike Calendly's one-link free plan). Paid Teams tier (low-double-digits/seat/mo) only if you need round-robin or to drop branding.

  • TallyThe qualifier. A 3-question form that gates the calendar so you book real buyers, not tire-kickers.

    $ Free with unlimited forms and submissions, conditional logic, calculations, and hidden fields all included. Pro (flat monthly) only to remove branding or add a custom domain.

  • MakeThe wiring. The automation runner that connects form → CRM → email → Slack so nothing is manual.

    $ Free plan covers 1,000 operations/mo, plenty for early inbound volume. Core tier starts at single-digit dollars/mo (annual) for 10,000 ops when you outgrow it.

  • HubSpot CRMThe memory. Every lead lands as a contact with a deal, so you actually follow up instead of losing them in a tab.

    $ Free CRM forever, up to 1,000,000 contacts and a deal pipeline at $0. You never need to touch the paid Hubs to run this recipe.

  • ResendThe instant reply. Fires a branded 'grab a time' email the second someone submits, from your own domain.

    $ Free tier sends 3,000 emails/mo (100/day) from one verified domain. Pro (low-double-digits/mo) lifts the daily cap once you scale.

  • RB2BOptional bonus: identifies anonymous visitors who DIDN'T fill the form, dropped into Slack so you can reach out first.

    $ Free plan resolves up to 150 companies/mo straight to Slack (person-level ID is US-only and trial-gated). Paid Starter adds person-level volume. Skip this entirely if you're not chasing outbound.

🔌 The wiring

  1. 1

    Put a Tally form behind your 'Book a call' button, 3 fields max: work email, company, and 'what are you trying to fix?'

  2. 2

    On submit, Tally redirects qualified leads straight to your Cal.com booking link (use hidden fields to pre-fill their name/email so booking is one click).

  3. 3

    Tally fires a webhook into Make on every submission, this is the spine of the whole thing.

  4. 4

    In Make: create/update the lead as a HubSpot contact + open a deal, so it's in your pipeline before you've read it.

  5. 5

    Same Make scenario triggers Resend to send an instant branded email: 'Saw your note, here's my calendar' with the Cal.com link.

  6. 6

    Add a Make step that pings a Slack channel with the lead's answers, so a hot buyer gets a human within minutes.

  7. 7

    Drop the RB2B pixel on your site (optional) so visitors who bounced without booking still surface in Slack for a warm outbound nudge.

✂ What to cut

Cut the all-in-one 'GTM platform' you're eyeing, the $300-1,500/mo tools that bundle a form, a scheduler, a CRM, enrichment, and sequences into one bill you'll use 10% of. You don't have the volume to justify it, and the bundle locks your data in. Also cut: the chat widget nobody mans, the 'demo request' that just emails a shared inbox, and any tool whose only job is to nag you to follow up, that's literally the one job you're handing to Make for free. Speed-to-lead beats feature count at your stage. One fast auto-reply will out-convert a fully-loaded sales suite that takes a day to respond.

The receipts

What it costs

$0 to start (every tool here has a real free tier). Realistically $0-20/mo once you outgrow Resend's daily cap or Make's free ops, the only near-certain spend is a domain.

Time to wire

an afternoon

What it replaces

A bundled GTM/scheduling/CRM suite (Calendly paid + Typeform + a paid CRM seat + an enrichment tool), which together run roughly $150-1,500/mo depending on how deep the upsell goes.

Where it breaks

It breaks at the seams between tools. Webhook field names drift when you edit the Tally form, Make's free ops run dry if traffic spikes, and Resend's 100/day cap bites on a launch day. Maintenance is light, mostly re-checking the Make scenario after you change the form.

Members · the full blueprint

The wiring, the configs, the templates, the Loom.

The free overview gets you the shape. The gated blueprint hands you the actual build: an importable Make scenario (the full Tally → HubSpot → Resend → Slack flow with error handling), a copy-paste Tally qualifier template, a Resend email that doesn't read like a robot wrote it, and a 9-minute Loom walking the whole wiring end to end so you can clone it without guessing field mappings.

How Sameer + Ankit wired it

Frame 1 of 8

The inbox graveyard

Sameer's landing page was working. Traffic, signups for the newsletter, the occasional 'hey, can we chat?' email. The problem: those emails sat for two days before he saw them. By then the prospect had booked a call with someone faster. 'We're not losing on product,' he said. 'We're losing on response time.'
