Attio
Attio is the modern CRM that has built the most credible challenger position to HubSpot in the startup and scaleup segment as of 2026. The company raised approximately $33M in total funding, with its latest Series B in 2024 led by Redpoint Ventures, and has built a product that prioritizes flexibility, data model customization, and native AI over the opinionated workflow structures of legacy CRMs. Attio AI — its embedded AI layer — surfaces contact enrichment, deal summaries, and workflow suggestions without requiring a separate AI add-on contract. The honest case for Attio is straightforward: it is the best CRM for relationship-driven, founder-led, or product-led companies that have outgrown a spreadsheet but are not ready for Salesforce’s complexity tax.
