Side-by-side comparison of AI visibility scores, market position, and capabilities
Online appointment booking platform for 50K+ service businesses acquired by Squarespace Apr 2019; $20-61/month with Stripe/Square payments, SMS reminders, intake forms, competing with Calendly and Vagaro for beauty/wellness/coaching scheduling automation.
About
Acuity Scheduling is an online appointment booking platform — acquired by Squarespace in April 2019 (Squarespace's first acquisition) — providing service-based businesses in wellness, beauty, coaching, tutoring, and professional services with a comprehensive scheduling solution including calendar syncing, automated email and SMS reminders, payment processing (Stripe, Square, PayPal), recurring bookings, group sessions, client intake forms, and custom branding. Founded in 2006 and supporting 50,000+ businesses at the time of acquisition, Acuity Scheduling became part of the Squarespace ecosystem as a complementary scheduling product for website builders and service businesses. In 2025, Acuity's pricing tiers range from $20/month (entry-level, 1 calendar) to $34/month (Growing, 2-6 calendars) to $61/month (Powerhouse, 36 calendars), integrated into Squarespace's website builder and commerce platform.
Serverless GPU cloud platform for AI/ML with Python-native deployment and per-second billing; developer-favorite scaling from zero competing with Replicate and Beam for AI compute.
About
Modal is a serverless cloud computing platform purpose-built for AI and machine learning workloads — providing on-demand GPU compute that scales instantly from zero with per-second billing, container management, distributed training support, and a Python-native developer experience that makes running ML workloads in the cloud feel as simple as running code locally. Founded in 2021 in New York City and backed by Redpoint Ventures and other investors, Modal has grown rapidly as AI development has accelerated demand for flexible, developer-friendly GPU infrastructure.\n\nModal's developer experience is its primary differentiator — engineers write Python functions decorated with @modal.function() and deploy them to the cloud with a single command, with Modal handling container building, GPU provisioning, auto-scaling, and execution. The platform supports training jobs that need distributed compute across multiple GPUs, model serving endpoints that scale to zero when unused (eliminating idle GPU costs), and batch inference jobs that process large datasets. The per-second billing model means developers pay only for actual compute time, not provisioned instances.\n\nIn 2025, Modal competes in the AI infrastructure market with Replicate, Beam, Banana, and major cloud providers' managed ML services (AWS SageMaker, Google Vertex AI, Azure ML) for serverless GPU compute. The market for AI-specific cloud infrastructure has grown dramatically as the number of ML engineers deploying models to production has expanded — traditional cloud providers require significant DevOps expertise to use GPU instances effectively, while Modal's Python-native approach reduces the barrier to entry. Modal has attracted a strong developer following among AI researchers and ML engineers building production AI applications. The 2025 strategy focuses on growing the developer community, adding enterprise features (dedicated GPU capacity, private networking, compliance), and expanding the hardware options available (H100 GPUs, custom accelerators).
