The call

Acuity survives as a small, lightly staffed feature inside Squarespace while Calendly and AI-native rivals like Cal.com pull ahead on scheduling itself.

Acuity Scheduling lets small businesses and service providers book appointments online, and it comes bundled with Squarespace websites. Right now it is hard to copy because it sits inside Squarespace, which locks in customers, but that advantage belongs to the parent company, not Acuity itself. The real problem is that Calendly (the market leader), Microsoft (which gives free booking through Office 365), and newer AI tools like Cal.com are shipping smarter features like AI phone agents and predictive booking, while Acuity's small 12-person team has shipped almost nothing. The one thing that could change the picture is if Squarespace decides to invest in AI features for Acuity over the next six months, but if nothing happens by the end of 2026 while competitors keep shipping, it will likely be abandoned or sold off.

Why
01
AI pressure: Cal.com AI phone-booking agent and ServiceAgent AI voice booking. Cal.com and ServiceAgent already sell AI agents that answer calls and book appointments; Acuity ships no AI booking feature at all. Could AI do the core job? Yes, likely.
02
Bigger players: Calendly and Microsoft Bookings. Calendly holds 22-30% of US scheduling share and started shipping predictive booking in August 2025; Microsoft Bookings comes free with M365. Could a giant copy it? Yes, easily.
03
What protects it. Bundling inside Squarespace websites keeps small-business site owners from switching, but that only covers a slice of the market.
What would change this call
Squarespace ships an AI/conversational booking feature under the Acuity brand by end of 2026. Would show parent is investing to defend Acuity rather than letting it stagnate.
Acuity's headcount (currently ~12) grows or shrinks over the next year. Growth signals parent commitment; stagnation or cuts signal neglect.
Permira announces a sale or divestiture of Acuity, echoing the 2024 Tock-to-Amex sale. Would confirm Acuity is being treated as a disposable asset, not a strategic product.
Key numbers
  • Acuity holds ~2.2% of US scheduling market (2026-04-13)
  • Calendly holds 22-30% share versus Acuity's 2.2% (2026-04-13)
  • Acuity runs on just 12 employees (2026-06-21)
Named risks
  • No AI feature parity while Calendly and Cal.com ship agentic booking, Aug 2025 onward. Severity: high
  • PE owner Permira may divest Acuity as it did sibling product Tock, sold to Amex in 2024. Severity: medium
  • Tiny 12-person team signals limited parent investment, risking further stagnation. Severity: high
  • Standalone paid add-on model exposed to free bundled alternatives from Microsoft and Square. Severity: medium
  • Brand consolidation confusion from 2025 Acuity/Squarespace Scheduling merge still unresolved mid-2026. Severity: low

Questions people ask
Is Acuity Scheduling profitable and how big is its business?
Acuity Scheduling does not disclose standalone financials since it is folded into parent Squarespace. A third-party estimate (Growjo, methodology unclear) puts annual revenue near $2.3 million as of March 2026, run by a team of roughly 12 employees per Crustdata, June 2026.
Could AI replace Acuity Scheduling?
Acuity's core functions, booking pages, reminders, intake forms, are commoditized and being targeted directly by AI-native rivals. Calendly shipped predictive/agentic scheduling from August 2025 and Cal.com launched an AI phone-booking agent; no comparable AI feature has shipped on Acuity as of mid-2026.
Who owns Acuity Scheduling?
Acuity Scheduling has been owned by Squarespace, Inc. since April 2019, its first-ever acquisition. Squarespace itself was taken private by Permira in an all-cash deal worth about $6.9 billion ($44.00/share), announced May 13, 2024 and closed in October 2024.
Is Acuity Scheduling losing market share to Calendly?
Yes. Per scheduling-software trackers as of April 2026, Acuity holds roughly 2.2% US market share versus Calendly's 22 to 30% and Cal.com's 7 to 9%, positioning Acuity as a distant challenger in the appointment-scheduling category.
Has Acuity Scheduling shipped any AI features?
No Acuity-specific AI feature launches were found as of mid-2026; reviewers describe the product interface as largely static since the 2019 Squarespace acquisition. Parent Squarespace markets AI-powered design tools elsewhere on its platform, but not within Acuity's scheduling product.
What is Acuity Scheduling's biggest competitive threat?
Calendly is the dominant incumbent with 22 to 30% US market share and agentic scheduling features shipped from August 2025. Cal.com (7 to 9% share, AI phone-booking agent) and bundled free tools like Microsoft Bookings and Square Appointments also pressure Acuity's standalone position.
