Company profile
researched Aug 2026Mubit is a British software company developing an execution memory and continual-learning layer for production AI agents. Rather than storing conversational history or embedding-based search results, the platform records each agent run in full β model calls, tool invocations, outcomes and user reactions β converts those runs into reusable decision traces or "lessons", and surfaces the relevant prior experience at the moment an agent makes a decision. Outcomes are fed back into the loop, with the stated aim of letting agents improve without repeated retraining or fine-tuning.
The product is delivered as a hosted control plane and console. Users create projects that are pinned to a region (EU, US or AP) and managed as platform instances; within each project they define Agent Cards (named agents with roles and versioned system prompts), Skills (tools and playbooks bound to an agent or shared), and browse stored facts, traces and lessons via a memory view, with a sandbox for seeding data and running raw queries plus live runtime logs. A documented HTTP control-plane API covers ingestion (/v2/control/ingest) and project, agent and prompt management (/v2/control/projects, /v2/control/projects/agents, /v2/control/prompt/get, /v2/control/prompt/set), including automatic minting of a new prompt version when in-code instructions drift from the stored active version. Beyond memory, Mubit describes deploying and operating inference for a customer's own model tuned to their workload, with the data, model and learning loop remaining under the customer's control.
The company also maintains a public GitHub organisation (mubit-ai) with repositories including a Claude Code plugin marketplace described as persistent, typed, self-improving memory, a TypeScript project called Minima with a Homebrew tap for its CLI, and several demo and benchmark repositories, among them a memory adapter and results for the StuLife lifelong-learning benchmark.
Founding story
Dutta and Peri, coming from mathematics and computer science backgrounds, built Mubit to address the repetitive and time-consuming work of teaching AI agents specific tasks, given that agents tend to forget what they have learned and restart from scratch with each training iteration. Their answer was a memory layer that lets agents retain knowledge and improve over time.
Business model
B2B SaaS. Mubit is offered as a managed, multi-region platform with a free self-serve tier requiring no credit card, and usage-based pricing with volume discounts negotiated directly ("talk to us"). The console shows per-instance billing driven by plan size (SMALL/MEDIUM/LARGE), stored data volume and operation counts, alongside a redeemable credit-code mechanism.
Usage-based pricing with volume discounts as usage grows; per-instance subtotals are computed from an instance plan tier together with storage consumed and operations executed. Plans are tailored to the customer's workload rather than published as fixed tiers.
Traction
About $2.1 million raised and roughly 1,500 engineers on the pre-launch waitlist while in closed beta (April 2026). Third-party adoption is evidenced by a published technical review of a hackathon project (CafeTwin) that used Mubit as its persistent memory layer and agent/prompt registry across two PydanticAI agents. The public GitHub organisation lists 16 repositories, with the Claude Code plugin marketplace repository the most starred at 14 stars as of August 2026.
Latest developments
As of April 2026 the company was in closed beta with a waitlist of nearly 1,500 engineers, and its cofounders appeared on the Forbes 30 Under 30 Europe AI 2026 list. Repository activity in August 2026 includes an official Mubit marketplace for Claude Code plugins, a Homebrew tap for the Minima CLI, and a memory adapter with full-stream results for the StuLife lifelong-learning benchmark. An independent developer review published on DEV Community documented a production integration covering memory ingestion/recall and the agent registry with prompt drift detection.

Market position
Early-stage venture-backed startup, in closed beta as of April 2026 with a pre-launch waitlist of nearly 1,500 engineers and about $2.1 million raised. Its cofounders were listed on the Forbes 30 Under 30 Europe AI 2026 list, and it is a portfolio company of Hoxton Ventures (Hoxton IV fund).
Positioned against agent-memory products that are either chat-history wrappers or vector stores: an independent reviewer noted that semantic search returns approximately similar items whereas Mubit returns the exact prior recommendation for a matching pattern together with the recorded human reaction to it. The bundled agent registry and automatic prompt versioning replace ad-hoc git-and-folder prompt management, and the data model is simple enough to mirror locally for offline fallback. The company also emphasises customer ownership of the resulting data and model.
Technology
A four-stage loop β capture (full recording of calls, tools and outcomes), extract (turning runs into lessons about what worked and failed), recall (surfacing the relevant lesson at the decision point) and reinforce (feeding outcomes back). The service is framework- and model-agnostic and exposes a REST control plane; ingestion items carry item_id, content_type, text, intent, lane, agent_id, metadata JSON and occurrence time, with server-side deduplication keyed on stable item_ids and 422 validation errors on missing required fields. The control plane additionally provides an agent registry and prompt version management with drift detection and retirement of superseded versions. Deployment runs on a Kubernetes-style runtime exposing pod, CPU, memory, disk and P95 latency telemetry across EU, US and AP regions; marketing cites sub-80ms recall, and an independent reviewer observed recall latencies consistently under 100ms including network round-trip from London.
Go-to-market
Self-serve product-led entry through a free tier and documentation, supported by a console and SDK/API integration, with a "talk to an engineer" path for larger workloads and custom pricing. Distribution also runs through open-source channels: an official Claude Code plugin marketplace, a Homebrew tap for the Minima CLI, and public demo and benchmark repositories. Developer awareness is reinforced by third-party technical reviews and a product newsletter.
Engineering teams running AI agents in production, including developers building multi-agent pipelines who need agents to retain state between runs; enterprise AI agent deployments are cited by its investor as the target setting. Roughly 1,500 engineers had joined the pre-launch waitlist as of April 2026.
Geography
UK-based; Nordic9 lists offices in Aberdeen and Hoxton Ventures gives its headquarters as Aberdeen, Scotland. The platform runs managed instances across EU, US and AP regions, with EU (Frankfurt) shown as the default region in the console.
History
Founded in November 2025 by Shankha Dutta and Anil Peri, who have backgrounds in mathematics and computer science. Hoxton Ventures records the founding year as 2025 and its investment in 2026. By April 2026 the company had raised approximately $2.1 million from investors including Hoxton Ventures and Heavybit and was operating a closed beta; public code repositories and third-party integrations appeared through mid-2026.
Risks & controversies
An independent reviewer flagged rough edges in the developer experience, including 422 errors caused by missing item_id and content_type fields that are easy to overlook in the documentation, and responses that may echo only the text field, prompting the reviewer to embed canonical JSON in the text payload defensively and to maintain a local JSONL mirror in case the API is unavailable. The same review noted its latency observations were informal rather than a systematic benchmark. The product remained in closed beta as of April 2026.
