What is not verified

The only revenue figure, US$17,000 a month, rests on one statement by co-founder Lennert Jansen, reported by Made With Models with the date July 2025 and marked as a maker claim with no proof shown. Its source is a Forbes Australia copy of a Forbes article of July 2025; Forbes does not allow Claude agents, so this page did not use that copy and could not read the original. Vibe Shipped repeats the same figure and is not an independent source. A reader could look for a payment-processor profile, a later founder interview or an investor statement with a dated revenue figure. The headline number is grade D: one claim or one estimate, with no second source. Aiolum shows it because the story is useful, and marks it so that it is not mistaken for a verified figure.

Airweave is a context retrieval layer: a service that sits between AI agents and a company's data sources and returns the pieces of data that are relevant to a question. It connects to apps such as Gmail, Stripe and document stores, syncs their contents into a searchable collection, and offers semantic search (search by meaning, using vector representations of text, not only by matching words) together with keyword and hybrid search. Agents call it through an SDK, a REST API or MCP, the Model Context Protocol, a standard way for an AI model to call outside tools.

Lennert Jansen and Rauf Akdemir founded it in 2025, according to its Y Combinator page, and presented it on Launch YC on 16 May 2025 in the Spring 2025 batch. On 2 July 2025 the company posted that it had raised a US$6 million seed round led by FCVC. Made With Models, a directory of AI money claims, listed in July 2025 that Jansen said Airweave was making US$17,000 a month, and it marks the number as a maker claim with no proof shown. The directory also reports that the first prototype was built with the AI app builder Lovable.

This page could not read the original interview: Made With Models cites a Forbes Australia copy of a Forbes article, and Forbes does not allow Claude agents. So the headline number is grade D, reported once and not verified. The page also shows earlier companies that tried to be the single connection point between software and many outside apps.

Airweave: US$17K a month reported, July 2025. Open-source context retrieval layer that lets AI agents search a company's apps and databases through one API, United States (San Francisco, per its Y Combinator page), team of 2 to 10, evidence grade D.

From a Y Combinator launch to a seed round in seven weeks. Each entry carries its grade.

03

Why did Airweave work?

Four causes, in the order they mattered. Each one is a reusable lesson.

01

Open source as the sales channel

The full product is on GitHub under the MIT license and runs with one script and Docker. Engineers try it for free, and the hosted plans sell the part they do not want to run themselves: syncing, scaling and support. About 6,500 people had starred the repository by November 2026.

02

One layer for many agents

The home page compares it with a retrieval pipeline built for each application: Airweave keeps one synced index that several agents and applications can reuse, so a team writes each connector once.

03

Usage limits as the price ladder

Plans differ by the number of source connections, queries and synced entities a month, from 50 queries on the free plan to 5,000 on the Startup plan, so the price grows with the amount of data an agent searches.

04

Fast prototype, then a rewrite

Made With Models reports that the first prototype was built with Lovable, an AI app builder. The current stack on GitHub is FastAPI in Python, React with TypeScript, PostgreSQL, the Vespa search engine for vectors and Temporal for background jobs.

How it was built

These details come from the GitHub page, the company's site and the Made With Models summary. They are grade C, except the Lovable prototype, which is a press report quoted by a directory. [6, 5, 1]

  • Backend: FastAPI (Python). Frontend: React and TypeScript with the ShadCN components.
  • Databases: PostgreSQL for metadata and Vespa for vectors. Workers: Temporal for orchestration and Redis for publish and subscribe.
  • Deployment: Docker Compose for development and Kubernetes in production, per the GitHub page.
  • Access for agents: Python and TypeScript SDKs, a REST API, an MCP server and integrations with agent frameworks.
  • Search modes listed on the home page: semantic, keyword, hybrid, time-aware and agentic search.
  • First prototype built with Lovable, per Made With Models; no source says which embedding or language models the hosted service calls.

Who tried this before Airweave, and why did they fail?

Three companies in our database of failed startups tried to be the single connection point between software and many outside apps or a team's scattered knowledge. The values below are from that database and are not independently verified.

Died 2011 to 2016Burned US$2.7M

Singly

The promise

One API to collect and sync user data from many social networks and online services.

Why it died

It depended on third-party APIs that changed and limited access, and broader automation tools such as Zapier and IFTTT took the market.

Competition
Died 2017 to 2020Burned US$2.8M

Niles

The promise

A Slack bot that answered questions from a team's collected knowledge.

Why it died

Slack and knowledge tools built similar features themselves, and the AI of the time was not accurate enough to make it sticky.

Competition
Died 2017 to 2025Burned US$81M

Solid

The promise

A unified API layer to connect CRMs, ERPs, HR systems and other business software.

Why it died

Each enterprise system had its own quirks, so sales cycles were long and support costs too high for the revenue.

Unit Economics

The failed startups come from our database of 1,749 dead startups, retold here in our own words. Its entries are AI-assisted summaries of public sources, so these cards carry no evidence grade.

What changed

Singly and Solid sold a unified connection to many outside systems and were worn down by the cost of keeping every connector working; Niles sold answers from a team's knowledge before language models could give them reliably.

Airweave sells the same kind of connector layer, but its buyer is now an AI agent that that needs current data from many apps. It also puts the connectors in open source, so outside contributors can add and repair them. Whether that keeps the maintenance cost below what Solid faced is not shown by any source: the only revenue figure, US$17,000 a month in July 2025, was stated by the founder and reported once.

05

Can one person copy Airweave now?

The open-source method, yes. The funded start, not for one person.

A solo founder can publish an open-source developer tool and sell a hosted version with usage-based plans. Airweave itself is a funded company of seven with a seed round and Y Combinator behind it, and its many connectors need steady maintenance.

Where it is still open: Narrower retrieval layers for one kind of data or one industry, where a small team can keep a few connectors in very good shape.

  1. 1Pick one piece of infrastructure that every AI agent builder needs and that you needed yourself.
  2. 2Publish the code under a permissive license with a one-command local setup.
  3. 3Sell the hosted version with a free tier and plans priced by usage limits.
  4. 4Offer the agent-native interfaces (SDK, REST, MCP) on day one.

What could go wrong for Airweave?

The risks are the mirror image of the causes above.

What is not verified

The only revenue figure, US$17,000 a month, rests on one statement by co-founder Lennert Jansen, reported by Made With Models with the date July 2025 and marked as a maker claim with no proof shown. Its source is a Forbes Australia copy of a Forbes article of July 2025; Forbes does not allow Claude agents, so this page did not use that copy and could not read the original. Vibe Shipped repeats the same figure and is not an independent source. A reader could look for a payment-processor profile, a later founder interview or an investor statement with a dated revenue figure.

Funded team, not a solo business

Two co-founders started it in 2025. It raised a US$6 million seed round in July 2025, and in November 2026 its Y Combinator page lists 7 employees and 5 open engineering roles, so the team may grow past 10.

Competition

Close neighbours on this site are Moss (a semantic search runtime for voice agents) and Metorial (an open-source MCP gateway for agents); large search and data companies also sell retrieval for AI agents.

Depends on model providers and other companies' APIs

No downloaded source names the embedding or language models the hosted service calls, so the dependence on model providers is not known. Every connector depends on another company's API (Gmail, Stripe and the rest), and the Singly and Solid records show how changes in those APIs raise the cost of a connector business.

Unsourced customer claims

The home page says "Trusted by engineering teams building the future" but the downloaded page shows no named customers or case studies.
