StackBest customer support & CRM for solo founders
When you are the only person answering support emails, the tool matters less than the bill attached to it. Most helpdesks and CRMs are priced for teams, so a solo founder can easily pay for seats, AI credits, and add-ons they never use. This category compares chat widgets, shared inboxes, and lightweight CRMs on what one person actually pays and how fast they can be up and running.
| Tool | Free tier | Paid from | Best for |
|---|---|---|---|
 Crisp$45/mo | $45/mo | Solo founders who want a free live chat widget today and a predictable flat bill later | |
 Intercom$29/seat/mo | $29/seat/mo | Founders who qualify for the Early Stage discount or expect heavy volume worth automating | |
 Plain$35/seat/mo | $35/seat/mo | B2B SaaS founders whose customers already live in shared Slack channels | |
 Chatwoot$19/agent/mo | $19/agent/mo | Cost-sensitive founders comfortable with open source, or anyone wanting an Intercom-style inbox for $19/mo | |
| €29/user/mo | Solo founders who need a free, fast CRM for pipeline and investor tracking, not for support tickets | ||
 folk$24/member/mo | $24/member/mo | Founders doing LinkedIn-heavy sales or fundraising who want a lightweight CRM and will pay for it | |
 Help Scout$25/user/mo | $25/user/mo | Solo founders doing email-based support who want a free start and a calm, simple inbox |
Start free: Help Scout's free plan (real shared inbox, 100 contacts/mo) for email support, or Crisp's free plan if you want a chat widget on your site, plus Attio's free tier if you also need a CRM. That combination costs $0/mo and covers most solo founders for months.
When you outgrow the caps, Chatwoot at $19/agent/mo or Help Scout Standard at about $21-25/mo is the sensible first paid step, keeping total support spend under $25/mo. Only move to Intercom or Plain when ticket volume justifies serious AI deflection, and if you do, apply to their startup programs first because list price plus per-resolution AI fees can run $300+/mo fast.

The fine print, tool by tool
Crisp$45/mo+
Crisp is a live chat widget plus shared inbox that bills a flat rate per workspace instead of per seat. A solo founder picks it when they want chat on their site today for free and a bill that stays flat if a cofounder joins later.
$45/mo (Mini, flat per workspace)
Free forever: 2 seats, live chat widget, 100 customer profiles, no AI credits
Billing is flat per workspace, not per agent, which is rare and founder-friendly. Trap: the free-to-paid jump is $0 to $45/mo with nothing in between, and AI conversations burn credits ($5 of credits, roughly 90 automated chats, on Mini). VAT added on top in the EU.
- + Free plan is genuinely usable solo: 2 seats and a real chat widget with no time limit
- + Flat workspace pricing, so adding a cofounder later does not double the bill (extra seats $10/mo)
- + Omnichannel inbox covers chat, email, WhatsApp, and Messenger in one place
- − First paid tier jumps from $0 to $45/mo with nothing in between
- − Free plan caps you at 100 customer profiles, easy to hit with any real traffic
Intercom$29/seat/mo+
Intercom is the full-stack support platform with chat, email, help center, and the Fin AI agent that answers tickets on its own. A solo founder picks it when they qualify for the Early Stage discount or when ticket volume is high enough that paying per AI resolution beats answering everything themselves.
$29/seat/mo (Essential, annual; roughly $39 month-to-month)
Advertised $29/85/132 per seat are annual prices; monthly billing runs about $39/99/139. The real trap is Fin at $0.99 per outcome, uncapped and billed on top of seats, plus paid add-ons (Copilot at $29-35/mo, Proactive Support Plus at $99/mo for 500 messages). Model your ticket volume before committing.
- + Fin AI agent is the strongest deflection bot in this list and is priced per outcome, so you only pay when it actually resolves a ticket
- + One seat on Essential at $29/mo is viable for a solo founder
- + Early Stage startup program gives up to 93% off plus 1 year of Fin free if you qualify
- − Fin costs $0.99 per resolution: 300 AI-resolved conversations a month is $297 on top of your seat
- − Add-ons stack fast: Copilot is $29-35/agent/mo, Proactive Support Plus $99/mo
Plain$35/seat/mo+
Plain is a support platform built for B2B companies whose customers ask questions in shared Slack channels, email, and in-app. A solo dev-tool or SaaS founder picks it when Slack is already where support happens and they want tickets flowing into Linear or Jira.
$35/seat/mo (Foundation)
Foundation is simple at $35/seat with 2,000 AI credits/mo, but the upgrade path is the trap: Horizon starts at $299/mo with 3 seats and $99 per additional seat, and Foundation caps at 5 users. Check the 50% startup discount before paying list price.
- + Built for B2B support in Slack, email, and in-app, which fits a dev-tool or SaaS founder's actual channels
- + AI agent included with 2,000 AI credits/mo on the base plan, no per-resolution fee
- + API-first with Linear and Jira integrations, plus a startup program at 50% off
- − No free tier and only a 7-day trial, the shortest evaluation window in this list
- − Second tier is a cliff: Horizon is $299/mo base (3 seats) plus $99 per extra seat, a 8.5x jump from one Foundation seat
Chatwoot$19/agent/mo+
Chatwoot is an open source Intercom alternative you can run on their cloud or self-host on your own server. A solo founder picks it when they want a multi-channel inbox at the lowest paid price in this list, or when owning their data matters more than managed hosting.
$19/agent/mo (Startups, billed annually)
Hacker plan: 2 agents, 500 conversations/mo, live chat only, 30-day data retention
Listed prices are annual-billing rates; budget the upfront payment. Free tier's 30-day retention means old conversations are deleted. AI beyond included credits is $20 per 1,000 Captain credits. Self-hosted community edition is free but unmanaged.
- + Open source (25k GitHub stars), so you can self-host for server cost only and own your data
- + Cheapest paid cloud plan in this list at $19/agent/mo with unlimited conversations
- + Startups plan covers all channels except voice, including WhatsApp, Instagram, and Telegram
- − Free plan is live chat only, with 500 conversations/mo and 30-day data retention, so history vanishes fast
- − Captain AI credits are thin (300/mo on Startups) and extra credits cost $20 per 1,000
Attio€29/user/mo+
Attio is a modern CRM that feels like a fast spreadsheet and fills itself in from your email and calendar. A solo founder picks it when they need to track deals, customers, or investors for free and do not need a support inbox.
€29/user/mo (Plus, annual; €36 month-to-month)
Free plan: up to 3 seats, 50,000 records, 3 objects, 200 emails/mo, 250 workspace credits/mo plus 100 seat credits per user/mo
Pricing page localizes to EUR in Europe (Plus €29 annual / €36 monthly; Pro €69 annual / €86 monthly, 20% annual discount). Trap: workspace credit add-ons (from €70/mo annual or €85/mo monthly for 5,000 credits) can quietly cost more than your seats if you lean on AI features. Free plan includes 250 workspace credits/mo plus 100 seat credits per user, which run out quickly.
- + Free tier is unusually generous for a CRM: 3 seats and 50,000 records costs nothing
- + Fast, spreadsheet-like UI that takes minutes to set up, no CRM consultant needed
- + Auto-logs emails and calendar, with built-in enrichment on every tier including free
- − It is a sales CRM, not a helpdesk: no shared support inbox or chat widget, so it only covers half this category
- − AI and enrichment run on credits, and extra workspace credits start at €70/mo (annual) for 5,000, which can exceed your seat cost
folk$24/member/mo+
folk is a lightweight CRM for managing contacts and outreach, with a Chrome extension that imports people straight from LinkedIn. A solo founder picks it when sales or fundraising runs through LinkedIn and they want a pipeline tool that takes an afternoon, not a week, to set up.
$24/member/mo (Standard, annual; $30 month-to-month)
Advertised $24/member/mo requires annual prepay ($288/year); monthly is $30. Watch the per-member limits: 500 enrichments and 2,000 messages/mo on Standard, and only 1 account sync per member. It is a contact and outreach CRM with no support inbox, so it covers the sales half of this category only.
- + Very fast to set up, feels like a smart spreadsheet rather than Salesforce
- + folkX Chrome extension pulls contacts straight from LinkedIn in one click
- + Standard includes 500 email enrichments and 2,000 messages per member/mo, enough for solo outreach
- − No free tier at all, so you pay $24-30/mo from day 15
- − Standard allows only 1 synced email account per member; syncing a second address requires Premium at $48-60/mo
Help Scout$25/user/mo+
Help Scout is a shared support inbox that works like email, plus a knowledge base and a help widget. A solo founder picks it when support arrives by email, volume is under 100 conversations a month, and they want to start at $0 with no new workflow to learn.
$25/user/mo (Standard, monthly; about $21 annual)
Free plan: up to 5 users, 1 inbox, 1 Docs site, limited to 100 contacts helped per month
Free tier is capped by contacts helped (100/mo), not by seats. Annual billing saves 16% (Standard about $21/user, monthly $25). Watch add-ons: $10/mo per extra inbox and $20/mo per extra Docs site on annual billing, AI Answers at $0.75 per resolution after the trial, and Pro at $75/user has a 10-user minimum so it is off-limits solo.
- + Free plan supports 5 users and a real shared inbox, plenty for a solo founder under 100 conversations/mo
- + Email-first workflow that feels like Gmail, so there is nearly zero learning curve
- + AI Answers is pay-per-resolution at $0.75, cheaper than Intercom's $0.99, with a 3-month free trial
- − Free plan's 100 contacts/mo ceiling forces the upgrade the moment support volume grows
- − Extra inboxes cost $10-12/mo each and extra Docs sites $20-24/mo on top of seats
