Thread AI
Also known as: Lemma
Composable AI orchestration platform whose Lemma product lets enterprises build and run proprietary agents and workflows on an extended serverless workflow engine, with native human in the loop and tool calling, strong governance, and VPC or on premise deployment.
Thread AI, based in New York, builds composable AI infrastructure that lets enterprises and public agencies bring AI into the workflows that run their business, without replacing the systems they already have. Founded in 2023 by former Palantir engineers Angela McNeal and Mayada Gonimah, it raised a Series A from investors including Index Ventures, Greycroft, and Meritech Capital. Its flagship platform, Lemma, is a workflow orchestration layer for building and deploying proprietary agents and workflows, designed for the kind of enterprise complexity where a failed run has real business consequences.
Lemma treats reliable agentic work as an orchestration problem. It builds on the vendor neutral CNCF Serverless Workflow specification and extends it with AI native primitives, including human in the loop actions, compensating actions that can undo an autonomous decision, richer authentication, and native tool calling, so complex, stateful, event driven processes are explicit and durable rather than brittle. A Function Registry lets teams import existing API schemas over gRPC, OpenAPI, and soon GraphQL to embed first and third party business logic directly into workflows, avoiding fragile proxy layers, and state and memory are managed as an explicit primitive scoped to each run to prevent context bleeding. The structured design generates visual representations of every workflow, giving teams a way to test, observe, audit, and manage agent behavior, with an SDK and UI for both developers and the subject matter experts who review AI decisions.
Thread AI leans into control, governance, and reliability as architectural properties rather than bolt ons, with SOC 2 Type 2, GDPR, and HIPAA, deployment via virtual private cloud, on premise, or multi tenant SaaS, and identity provider integration so agents operate only within boundaries the organization controls. It is orchestration infrastructure rather than a finished agent, so its strengths are integration, orchestration, governance, and deployment, while knowledge grounding, persistent learning memory, and model routing are lighter. For an enterprise or public agency that needs to run agentic workflows in regulated, mission critical operations with strong control and on premise options, Thread AI is a strong fit; a team wanting a prebuilt vertical agent or a simple no code assistant will find it more of a foundational platform.

Funding status
Independent, based in New York, founded in 2023 by former Palantir engineers Angela McNeal and Mayada Gonimah. Thread AI raised a Series A from investors including Index Ventures, Greycroft, Meritech Capital, and Homebrew, with earlier backing from Plug and Play. Its founders bring deep enterprise systems experience, and the company positions Lemma as composable AI infrastructure for enterprises and public agencies running agentic workflows in regulated, mission critical operations.

Integrations
Lemma embeds first and third party business logic directly into workflows through a Function Registry that imports existing API schemas over gRPC, OpenAPI, and soon GraphQL, avoiding brittle proxy layers, and connects to existing systems without replacing them. It integrates with identity providers to govern access using existing groups and permissions, and extends the CNCF Serverless Workflow specification with native AI tool calling.
In practice
Your team wants to bring AI into core financial or back office processes, but a wrong autonomous action has real consequences. Thread AI's Lemma makes each step explicit, adds human in the loop checks, and can compensate to undo a decision cleanly.
Stitching agents together with brittle glue code and proxy servers breaks in production and hides failures. Lemma imports your existing API schemas directly and runs stateful workflows that complete exactly once or roll back.
Regulated operations demand audit trails, traceability, and on premise control that most AI tools cannot offer. Thread AI deploys via virtual private cloud or on premise with SOC 2 Type 2, GDPR, and HIPAA and full observability on every run.

Pricing
Not public; quoted through enterprise engagement, with VPC, on premise, or multi tenant SaaS deployment
enterprise subscription scoped to workflows, usage, and deployment model
What is public
No list pricing. Thread AI sells Lemma through enterprise engagement, with deployment via virtual private cloud, on premise, or multi tenant SaaS, but rates are not public.
Billing mechanics
Presumed enterprise subscription scoped to workflows, usage, and the deployment model, whether virtual private cloud, on premise, or multi tenant SaaS, though rates are not disclosed.
Cost watchouts
On premise or virtual private cloud deployments add infrastructure and operational effort, and workflow volume and complexity can raise cost as more processes move onto the platform.
Variable cost rationale
Priced as an enterprise platform scoped to workflow volume, run activity, and the deployment model, so cost grows as more mission critical processes move onto the platform and with the level of data control required.
Additional watchouts
Confirm how pricing scales with workflow volume and usage, and how the on premise or virtual private cloud deployment options affect both cost and the operational burden on your team.
Sales call required
Yes — required for paid access
Free / trial
Demo and pilot on request; no public free tier
Key ambiguities
No public rate is disclosed, and the pricing basis, whether per workflow, per run, per seat, or platform tier, and how the deployment model affects it, is not clear.
