Company profile

researched Aug 2026

Riveter is an AI web data extraction and enrichment platform delivered primarily as an API. Users describe the data they need in natural language, and Riveter's agents search the live web, navigate to relevant pages, and extract and structure the results, returning a finished dataset through a single request. The product covers four main functions: building datasets of companies, people, places or products from a prompt with no input data required; automating web research and enrichment of existing rows; returning consistently formatted structured output for ingestion into code, tools and reports; and scheduling projects to monitor sources for changes.

The platform's API exposes enrichment, dataset building, scraping, quick search and a search-agent endpoint, with asynchronous "runs" that can be polled or delivered via webhooks. Riveter publishes official TypeScript/JavaScript, Python, Ruby and Go SDKs, an MCP server for use from AI assistants such as Claude, Cursor, Codex and Windsurf, and a web app in addition to the API. Documented limits include a default rate limit of 30 requests per minute per endpoint group and row caps of up to 10,000 rows per enrichment request using a saved enrichment ID (1,000 rows with an inline configuration). The company states it handles bot detection, proxy management, headless browsing and site changes on the user's behalf, and can read PDFs, images and third-party APIs alongside web pages, combining them into one structured output.

Stated use cases span data and engineering teams replacing custom scraper infrastructure, pricing and competitive research, sales and go-to-market lead list building and enrichment, operations monitoring, and finance and risk work including KYB and compliance research. Industry applications listed include e-commerce, marketing, industry classification and real estate.

Founding story

Co-founders Abby Grills (CEO) and Cody Watters (CTO) each spent five or more years at Gusto before moving to Middesk and Retool respectively. They describe repeatedly encountering the same problem across engineering, data, operations and growth teams: the information needed was available on the web but there was no reliable way to get it into a structured, usable dataset at scale. Grills previously led 0-to-1 products at Gusto, including time tracking and state payroll tax registration, and worked on Address Risk at Middesk.

Business model

Riveter sells software access to its data extraction and enrichment platform, usable in-app, via API, or through its MCP server. Pricing is per action in credits rather than per seat, with a free plan, pay-as-you-go with automatic top-ups, a self-serve plan, and custom enterprise pricing.

Usage-based credit pricing charged per action, across free, pay-as-you-go, self-serve, and custom enterprise tiers, rather than per-seat licensing.

Traction

The Y Combinator company page and launch post state that teams at OpenAI, Snap and Fermat use Riveter to build datasets, and the site carries named testimonials from staff at Zeffy, Roundabout Technologies, Fermat and Multiply. Riveter has shipped multiple product iterations, from a spreadsheet AI data assistant and a corporate-strategy copilot through parallel AI search agents to a general web data API, and publishes SDKs in four languages plus an MCP server.

Latest developments

Riveter's most recent launch positions the product as prompt-to-dataset generation, where a single natural-language prompt produces a list and layered enrichments scraped live from the web, available in-app, via API or through the MCP server. The company has released a second-generation API (v2.0.0) with unified run lifecycle endpoints, webhooks, and official TypeScript, Python, Ruby and Go SDKs, while keeping first-generation endpoints working as legacy paths.

Full profile — market position, technology, go-to-market, geography, history

Market position

Riveter competes in the AI web data extraction, search and enrichment tooling market against index-based search/scrape APIs (Exa, Parallel, Firecrawl), GTM enrichment platforms (Clay) and traditional static data vendors. Its Y Combinator company page names Snapchat/Snap, OpenAI and Fermat among customers.

The company positions Riveter as a complete end-to-end system rather than a single search or scrape call, contrasting itself with tools such as Exa, Parallel and Firecrawl, which it says sell primitives that customers must assemble into pipelines and which rely on pre-built indexes. It also contrasts itself with static data vendors and with general-purpose assistants such as ChatGPT, Claude and Perplexity, arguing those cannot reliably return thousands of enriched records at scale. Additional claimed differentiators include live rather than cached data, resilience to site layout changes, and ability to read PDFs and images.

Technology

AI agents interpret web pages the way a person would rather than being coded against a specific page structure, which the company says allows the same configuration to keep working after site redesigns. Agents run multi-step workflows in a single request (for example, finding every dental practice in a city and then every dentist at each practice) and run in parallel across rows. The system fetches from live sites at query time instead of serving a pre-built index, and includes SERP/search, web scraping, headless browsing, proxy management, image reading and PDF parsing components; the company also states it extracts from complex sites without the cost and latency of full browser rendering. Delivery is via a versioned REST API (current version 2.0.0, with first-generation verb-style endpoints retained as legacy), webhooks, four official SDKs, and an MCP server that dynamically exposes API endpoints as tools.

Go-to-market

Self-serve signup with a free plan and free trial combined with a sales-assisted motion built around a 20-minute demo call, in which the team scopes the customer's workflow and configures their first project; a launch post offered 1,000 free credits to teams booking a demo. Developer-led distribution is supported through public API documentation, four official SDKs, npm/PyPI/RubyGems/GitHub packages, and an MCP server. The company also markets through Y Combinator launch posts.

B2B teams that depend on web data, including data and engineering teams, pricing and competitive research, sales and go-to-market/RevOps, operations and monitoring, and finance and risk functions; industries cited include e-commerce, marketing, real estate, and market research.

Geography

Headquartered in San Francisco, with a web-delivered API and app available to customers remotely.

History

Riveter was founded in 2024 and participated in Y Combinator's Fall 2024 batch. Its publicly listed launches trace an evolving product: an AI copilot for corporate strategy analysis, an AI data assistant for cleaning, labeling and enriching spreadsheet rows, thousands of parallel AI search agents for per-row web research, a Riveter API positioned to replace scraper infrastructure, and most recently prompt-to-enriched-dataset generation. The API has moved to a second generation (version 2.0.0), with the original verb-style endpoints maintained as legacy paths.
