## FluidStack

FluidStack is an AI compute provider that builds the physical layer underneath frontier model work: data centers, power, cooling and very large GPU clusters. Its public positioning is deliberately infrastructural rather than product-led — it describes building gigawatt-scale compute, bringing new sites online in months, and operating tens of millions of accelerators reliably. For teams training or serving large models, that translates into reserved, single-tenant-class capacity that is provisioned and operated for you rather than an instant, self-serve VM catalogue.

A distinguishing theme is the pairing of power and compute. FluidStack writes about redesigning compute and power infrastructure from first principles, developing off-grid solar to supply clusters, and using closed-loop cooling that fills tanks once and recirculates water indefinitely. It also emphasises building in the United States with onshored manufacturing, framing infrastructure ownership as a strategic question about which values shape the technology being built. For AI organisations, these are increasingly relevant because energy availability, not chip supply alone, is the binding constraint on scaling.

If you need a small number of GPUs for a day, FluidStack is probably not the fastest route; capacity is engaged at enterprise scale through a sales process. If you are planning a multi-month training run or a production inference fleet and want dedicated, purpose-built infrastructure with managed operations, it is a strong candidate to evaluate alongside the major hyperscalers and specialised GPU clouds.

**Pricing & Plans:** Enterprise and contact-for-pricing. FluidStack does not publish per-GPU-hour rates or a self-serve sign-up on its website; capacity is scoped and quoted through a direct sales conversation based on cluster size, duration and hardware. Catalogue listings classify it as a paid product requiring contact for pricing.

- **Datacenter-scale compute built in-house:** FluidStack designs and builds large AI data centers, including high-density campuses with significant per-site power capacity, rather than reselling capacity from other clouds.
- **GPU clusters for training and inference:** Clusters are architected for large-scale model training and inference, with high-bandwidth interconnect and orchestration suitable for distributed workloads.
- **Power and cooling engineered together:** The company develops off-grid solar and recirculating closed-loop cooling, treating power and water efficiency as core engineering problems.
- **Managed operations and reliability:** Smart hands, cluster provisioning and operations support let research teams focus on models while FluidStack runs the physical and orchestration layers.
- **US-built and onshored supply chain:** Data centers are built in the United States with onshored manufacturing of compute and power infrastructure, a deliberate supply-chain and sovereignty choice.

**Strengths:** Purpose-built AI infrastructure rather than generic cloud resale; Power, cooling and data center design handled in-house, which matters at scale; Managed provisioning and operations for large training and inference clusters; Explicit positioning on US-built, onshored infrastructure

**Limitations:** No published self-serve pricing or instant sign-up; access requires a sales conversation; Enterprise-scale focus means very small individual workloads may not be a fit; Capacity is concentrated in US locations, which may matter for latency-sensitive or data-residency-bound teams

## Otter AI

Otter AI began as an AI notetaker and has grown into what the company calls a "Conversational Knowledge Engine." At its core it transcribes meetings in real time, with live transcription, speaker recognition, and multi-language support. Every meeting becomes a searchable record rather than a lost recording. Otter then layers on summaries that include decisions, action items, and insights, plus automatic capture and assignment of next steps.

Beyond transcription, Otter positions itself as a meeting agent that works before, during, and after a call. It delivers pre-call briefings with prior discussions, action items, and updates, offers Live Assist coaching during conversations based on your history and company playbooks, and follows up automatically in the tools you already use. Otter AI Chat lets you ask questions across all your meetings and connected apps to generate follow-ups, reports, and other content.

Otter provides flexible ways to capture meetings: you can send an AI notetaker bot automatically, record bot-free on Mac, Windows, or Chrome, or record on mobile, and it supports live transcription and speaker recognition. Channels group meetings by team, project, or topic for shared collaboration, and an MCP Server lets ChatGPT, Claude, and other AI chat tools securely access your meeting knowledge. Otter markets enterprise-grade security, governance, and compliance controls, and highlights use cases across Sales (CRM sync, live coaching), Education (lecture transcripts, study notes), and Media (interview transcription and content creation).

**Pricing & Plans:** Freemium with paid tiers and enterprise options. Otter offers a free plan to start, plus individual paid plans and enterprise pricing available on request or by scheduling a demo. Specific tier prices are shown on the Otter pricing page and vary over time.

- **Real-time transcription with speaker recognition:** Live transcription in multiple languages with speaker identification, so meeting records are accurate and attributable.
- **Automatic summaries and action items:** Each meeting becomes a clear summary with decisions, action items, and insights, with next steps captured and assigned automatically.
- **Otter AI Chat over your knowledge base:** Ask questions across your meetings and connected apps to instantly produce follow-ups, reports, and content.
- **Live Assist and pre-call briefings:** Get briefing documents before a meeting and real-time, personalised coaching during calls based on your history and playbooks.
- **Flexible capture and broad integrations:** Record via an AI notetaker bot, bot-free desktop/Chrome, or mobile, and sync insights to CRMs and other tools; an MCP Server connects ChatGPT, Claude, and more.

**Strengths:** Accurate real-time transcription with speaker recognition and multi-language support; Automatic summaries and action items remove most manual note-taking; Otter AI Chat searches across meetings and connected apps for instant answers; Flexible capture options, including bot-free desktop and Chrome recording

**Limitations:** Pricing details and limits per tier change and require checking the pricing page; The most advanced coaching, analytics, and admin features sit in higher or enterprise tiers; Accuracy can vary with audio quality and heavy accents or overlapping speakers
