Founder-led sales: a CRM + follow-up stack you can run solo
You're a pre-Series-A founder doing your own sales, DMs, demos, follow-ups, and the deals are starting to outrun your memory.
Wired & tested by Sameer + Ankit
Free · the verdict
You don't need a sales platform. You need a CRM that doesn't fight you, a booking link wired to it, an AI notetaker writing your follow-ups, and one sender for cold outreach, glued by Make so you never copy-paste a lead again. Five logins, runs from your phone, costs less than one seat of the bloated thing your investor told you to buy.
The stack
Attio
Cal.com
Fathom
Instantly
Make
Google Workspace
- AttioThe CRM brain, every lead, deal, and conversation lives here. Modern, fast, models your pipeline however you actually sell instead of how Salesforce thinks you should.
$ Free for up to 3 users (250 automation credits/mo). Plus from ~$29/seat/mo and Pro ~$69/seat/mo (annual). A solo founder runs free for a long time.
- Cal.comThe booking link in your email signature and on your site. When someone books a demo, it triggers the whole machine.
$ Free Forever plan with unlimited event types, calendar connections, and built-in workflows. Paid Teams ~$15/seat/mo only when you add people. Open-source if you want to self-host.
- FathomAI notetaker that joins your calls, transcribes, summarizes, and spits out action items, so the post-demo follow-up writes itself.
$ Genuinely free for individuals: unlimited recordings + transcription. Paid Team tiers (listed around the high-double-digits/mo) add structured CRM field write-back. Solo = free.
- InstantlyThe cold outreach + sequencing engine for top-of-funnel: warmup, multiple inboxes, and follow-up sequences that don't torch your domain. (Smartlead is the near-identical swap.)
$ Free trial; entry sending plan listed around $30/mo (Smartlead's comparable tier ~$39/mo). Scales by inbox/volume. Verify current tiers before you commit.
- MakeThe glue. The invisible operator that moves a lead from Instantly reply → Attio, from Cal.com booking → deal, from Fathom summary → follow-up task. No copy-paste, ever.
$ Free plan with 1,000 ops/mo and full multi-step scenarios. Paid from ~$9/mo for 10,000 ops, roughly 3-4x cheaper than Zapier at the same volume.
- Google WorkspaceYour sending identity, business email on your own domain so your outreach lands in inboxes, not spam folders. Powers Gmail, Cal.com sync, and Fathom's calendar hook.
$ Business Starter ~$6/user/mo (annual) / ~$7 monthly. You're paying for deliverability and a domain that isn't @gmail.com.
🔌 The wiring
- 1
Make Attio the single source of truth. One pipeline, a few stages (New → Booked → Demo'd → Proposal → Won/Lost). Don't model it like an enterprise, model it like your actual deals.
- 2
Drop your Cal.com link in your email signature and on the site. Connect it to Make so every new booking creates (or updates) a Person + Deal in Attio at the 'Booked' stage, instantly, no manual entry.
- 3
Add Fathom to your calendar so it auto-joins demos. After each call, route the summary + action items into the matching Attio deal via Make, and create a 'send follow-up' task due tomorrow.
- 4
Run cold outreach in Instantly off your Google Workspace domain (warm the inboxes first). When a prospect replies positively, Make pushes them into Attio as a new lead so a hot reply never dies in your inbox.
- 5
Wire one Make scenario to nudge you: any deal sitting in a stage for 5+ days with no activity gets flagged, a Slack ping or a task in Attio. This is the follow-up discipline a solo founder always loses.
- 6
Close the loop: when a deal hits Won or Lost in Attio, have Make stop any active Instantly sequence and log the outcome. No awkward 'still interested?' email to someone who already signed.
- 7
Optional power step: pipe inbound form fills (from your site) straight into the same Make → Attio flow, so every lead, booked, cold, or inbound, lands in one pipeline you check once a day.
✂ What to cut
Cut the CRM your investor recommended. You do not need Salesforce, HubSpot Sales Hub Pro, or a $300/seat 'revenue platform' to manage 40 open deals you can name from memory. Those tools are priced for teams with a RevOps hire, you are the RevOps hire. Cut the standalone scheduling tool (Cal.com does it free), the standalone notetaker subscription if you're solo (Fathom's free tier is real), the 'sales engagement platform' that's just sequences you can run in Instantly, and every Zapier dollar you're spending that Make does for a quarter of the price. The rule: if a tool's killer feature is one field syncing to another field, that's a Make scenario, not a subscription. Buy software for the work; wire the connections yourself.
The receipts
What it costs
$0-50/mo to start (most pieces run free solo; ~$40-50 once you add the sender + Make's first paid tier + a domain). A real sales-stack equivalent runs $200-500+/mo.
Time to wire
an afternoon
What it replaces
A $300+/seat CRM platform (Salesforce / HubSpot Sales Pro), a paid scheduler ($10-15/seat), a separate notetaker ($19-29/seat), a sales-engagement tool ($60-100/seat), and a Zapier plan, collapsed into mostly-free tools plus one glue subscription.
Where it breaks
It breaks where every founder stack breaks: deliverability. Cold sending will land you in spam if you skip inbox warmup or blast a bad list, that's an Instantly hygiene problem, not a stack problem. The Make scenarios are set-and-forget but need a 10-minute check when a tool ships an API change. And it stops being 'basically free' the day you hire a second seat, at which point Attio Plus and a real notetaker tier are still cheaper than the platform you didn't buy.
