What stack should I start with?
Not every operator starts the same way. The four core Stacks below cover the functions every new business eventually needs — CRM, email marketing, HR, and project management. Pick the one that matches your immediate bottleneck, and add the others as you grow.
Direct answer: most new operators should start with a CRM (HubSpot free tier is the default) plus a project management tool (ClickUp or Asana free tier). Add an email marketing tool when you have an audience, and HR software (Gusto) the moment you hire your first employee.
The four core Stacks
Pipeline & contact management
Track leads, deals, and customer conversations in one place — the foundation for any operator who runs sales calls, proposals, or renewals.
Newsletters & automations
Send newsletters, drip onboarding, and behavioral automations — the lowest-cost way to stay top-of-mind with leads and existing customers.
Hiring, onboarding & payroll
Hire, onboard, pay, and retain a team without reading a 200-page HR handbook — built for operators adding their first employee.
Tasks, deadlines & accountability
Run projects, hit deadlines, and keep a small team on the same page — without the spreadsheet-and-Slack-ping chaos.
How to pick
The cheapest starter stack is the one you actually use. Most operators over-buy tools they never open. Start with a free tier, log one real workflow through it for two weeks, and only pay for an upgrade when you hit a real ceiling — not when the marketing page says so.
If you already know you have a specific blocker (a sales pipeline you cannot track, a team you cannot pay, an audience you cannot reach), jump straight into the matching Stack page below. If you have no specific blocker yet, the CRM Stack is the canonical place to start. Everything else connects to it.
Frequently asked questions
Do I need all four Stacks at once?
No. Most new operators start with one or two — typically CRM (to track leads and customers) and Project Management (to keep work organized). Add Email Marketing once you have an audience worth sending to, and HR the moment you hire your first employee beyond yourself. A solo founder rarely needs all four on day one.
What if I already use Google Workspace?
Google Workspace covers docs, email, calendar, and storage — but it is not a substitute for any of the four core Stacks. Most operators keep Google Workspace for the underlying productivity layer and layer CRM (HubSpot, Pipedrive), PM (ClickUp, Asana), Email Marketing (Kit, Mailchimp), and HR (Gusto, BambooHR) on top. Think of Workspace as the foundation; the four Stacks are the business functions.
Which Stack should a solo founder start with?
For a solo founder with no team and no productized offer yet, start with CRM. HubSpot CRM is free for unlimited users; Pipedrive has a 14-day trial. You will use it the moment you take a sales call or email inquiry, and it compounds: every contact you log now is a relationship you can re-engage six months later. Add the other three Stacks only when you hit a specific trigger (first hire, first 1,000 subscribers, first recurring client deadline).
Do the four Stacks replace each other or stack together?
They stack. CRM tracks who you sell to. Email Marketing nurtures them between purchases. PM keeps the work moving. HR handles the people doing the work. The mistake most new operators make is trying to find one tool that does all four — the result is usually a "jack of all trades" CRM that does PM poorly. Pick a dedicated tool per Stack. They integrate with each other through Zapier, native connectors, or webhooks.
What does a starter stack cost per month?
A lean starter stack (one tool per Stack) costs roughly $80–$200/month in 2026. CRM free (HubSpot) to $50/mo (Pipedrive). Email Marketing free (Kit up to 1,000 subscribers) to $29/mo (ActiveCampaign Essentials). PM free tier (ClickUp, Asana, Trello) to $12/mo (Notion Plus). HR $40/mo + $6/employee (Gusto, only when you hire). The four core Stacks together, all paid, hit roughly $150/month for a 3-person team.
Should I buy the BizStackHub products before trying the free tools?
No. Use the free tiers first — HubSpot CRM, Kit (ConvertKit) up to 1,000 subscribers, ClickUp free, Gusto’s 30-day payroll trial. You will outgrow the free tier only if you hit a specific ceiling (more than 1,000 email subscribers, more than 100MB of CRM data, more than 5 team members in PM). Paid BizStackHub products like Mail Stack ($49/mo) make sense once you have validated the workflow and are ready for higher-volume tools.
How is BizStackHub different from a single all-in-one platform?
BizStackHub is the decision layer, not the execution layer. We recommend which tool belongs in each Stack — we do not run your CRM or email server. All-in-one platforms (GoHighLevel, HubSpot Marketing Hub) bundle CRM + email + PM into one bill; they trade flexibility for simplicity. If you need flexibility, tune your own Stack. If you want one bill and an opinionated workflow, an all-in-one can work — just expect to compromise on at least one Stack.
