Attio is the better starting point for most B2B startups. It's fast to set up, flexible enough to match how you actually sell, and a fraction of HubSpot's cost at early stages.
Attio is the better starting point for most B2B startups. It's fast to set up, flexible enough to match how you actually sell, and a fraction of HubSpot's cost at early stages. HubSpot makes sense once you need deep marketing automation or have a larger sales team.
What is Attio?
Attio is a CRM that works like a well-designed spreadsheet with a relational database underneath. You can add custom attributes, build filtered views, and create automations that match your actual sales process — without touching code. It doesn't impose a pipeline structure before you know what your pipeline actually looks like.
What is HubSpot?
HubSpot is an all-in-one CRM and marketing platform. Its paid tiers give you marketing automation, email campaigns, sequences, reporting dashboards, and a large ecosystem of integrations. HubSpot is the dominant choice for B2B companies that want CRM and marketing under one roof.
When to choose Attio
Pre-Series B and still refining your sales process. Running a relationship-driven sales motion where flexibility matters. Using Clay for outbound — the native integration is clean. A small team (under 20 reps) that doesn't need HubSpot's marketing suite.
When to choose HubSpot
Running inbound marketing campaigns that need to tie back to CRM data. A team of 20+ reps that needs structured pipeline stages and permissions. Already using HubSpot's marketing tools and want everything in one place. Post-Series B with dedicated ops to manage the configuration.
Can you start with Attio and move to HubSpot later?
Yes — and it's the path most companies take. Start with Attio while your process is forming. Attio exports cleanly and has full API access, so migration to HubSpot later is manageable. We recommend Attio for companies starting from scratch. You can have it configured and live in a day.
