Company profile
researched Aug 2026Autobound is a B2B signal intelligence company that aggregates buying signals and delivers them to go-to-market teams, data platforms, and AI-native sales tools. Its catalog covers 700+ signals across 35 signal types drawn from 35+ sources, resolved to 250M+ contacts and 50M+ companies, with each signal timestamped, attributed to a source, and mapped to a company and contact. Signal categories include hiring and growth, financial and funding events, technology and product changes, leadership and people moves, intent and engagement, and company/market data. Data is refreshed on a daily-to-weekly cadence.
The company began as an AI sales-email tool: a free Chrome extension that researched the recipient of a drafted email or a LinkedIn profile and suggested hyper-personalized openers and emails, drawing on individual details (role initiatives, job changes, promotions, interests) and company events (funding rounds, acquisitions, press releases, competing technologies). "Autobound Anywhere" extended this to Gmail, LinkedIn, Outreach, Salesloft, HubSpot, and Salesforce. Third-party review coverage characterizes the product as strong at AI email personalization for teams already running sequencers, but notes that output can read generic without editing, that tone and structure controls are limited, and that the LinkedIn capability generates InMails and connection requests for manual sending rather than automating outreach.
Today the platform is positioned as data infrastructure: a REST API (advertised sub-200ms responses, 99.9% uptime SLA), scheduled batch exports to Google Cloud Storage in CSV/JSON/Parquet, an MCP server for LLM and agent use cases, and white-label OEM licensing. A vendor case study states Autobound's data powers products from ZoomInfo, 6sense, RocketReach, and TechTarget through OEM licensing. A newer initiative layers closed-won deal outcomes on its signal base to build a predictive buyer-intent engine.
Founding story
CEO Daniel Wiener, previously the second-highest performing BDR in Oracle's US sales division, co-founded Autobound with Kyle Schuster, formerly Yelp's top global sales manager, and Tanner McRae, who spent six years on Amazon's R&D and machine learning teams. Wiener has described concluding, after five years in tech sales, that no AI-powered platform existed to address the daily inefficiencies salespeople faced, and setting out to build it. The company was a Founder Institute San Francisco portfolio company and among the top 2% of that program's 4,000+ portfolio companies.
Business model
Autobound sells access to its signal data rather than seats. Buyers consume data through a REST API, scheduled flat-file delivery to their own infrastructure, or OEM/white-label licensing that embeds the signals in the customer's own product with custom SLAs. Earlier in its life the company distributed a free-to-install Chrome extension with a planned premium tier.
Usage-based credit packs purchased one-time rather than by subscription, with credits that do not expire: Starter $19 (2,000 credits), Growth $49 (5,444), Scale $149 (19,867), Pro $499 (83,167), Business $1,299 (288,667) and Enterprise $4,999 (1,249,750 credits), with enterprise packs quoted from $10,000 (2.6M credits) to $40,000 (11.5M credits) and custom rates beyond. Search costs 2 credits per result, enrichment 2 credits per signal returned, buyer intent 1 credit per contact, and bulk exports 50 credits plus 5 per topic with unlimited rows; zero-result requests and catalog browsing are free and new accounts receive 1,000 free credits. Flat-file bulk data licensing is sold on custom contracts.
Traction
Reported figures include 3.8B+ signals processed, 250M+ contacts and 50M+ companies covered, and 250+ G2 reviews averaging 4.9/5. Customer-reported outcomes cited by the company: 18x ROI in three months and a 279% increase in BDR activity at Skuid; $400K+ saved versus in-house build and a 30% retention increase at TechTarget, which embedded the signal API into Priority Engine; 500K+ dormant leads activated at an enterprise HR software company; and 100+ new signal types in production within four weeks at AiSDR. Earlier milestones reported around the seed period were users at 250+ companies, and at an earlier stage 13 paying customers on the HubSpot marketplace with 85 companies on a waitlist, zero churn, and a doubling of user count alongside ~200% growth in campaigns sent per user.
Latest developments
In July 2026 the company announced a partnership with 5x5, the data co-op behind Market Pulse, to power its resolution graph and buyer intent products and to train a predictive intent engine on real closed-won outcomes. Also in July 2026 it added real-time email verification to the Signal API (SMTP handshake, MX validation, AI catch-all detection, priced at 1 credit per email) and published backtest results from a signal-native buying predictor run over 82.8M signals, reporting up to 7.6x the accuracy of random targeting in flagging future software buyers. It is recruiting contributors of anonymized deal data for "The Intent Initiative" in exchange for early access.

Market position
Positions itself as a signal/data layer beneath GTM and AI sales tooling rather than as a full outbound suite, and claims to replace multiple point data vendors for platform customers. A vendor case study says the product ranks third among 85 active competitors in its category with 250+ G2 reviews averaging 4.9/5, and the pricing page claims the "#1 AI Sales Tool on G2" badge. Independent review coverage frames it as a writing assistant that complements, rather than replaces, prospecting and multichannel outreach platforms such as SalesRobot.
Emphasis on transparency and structure in intent data β every signal timestamped, sourced, and resolved to a specific company and contact rather than delivered as an opaque score β plus breadth (700+ signals, 35+ sources), delivery flexibility (API, flat file, OEM white-label), latency under 200ms, daily-to-weekly refresh, and consumption-based credits that never expire. Its intent work is framed around backtested predictions on real closed-won outcomes rather than black-box modeling.
Technology
An API-first architecture built on Vue.js and Node.js after a rebuild away from an AngularJS prototype, centered on an insights database that consolidates signals such as funding rounds, hiring trends, product launches, leadership changes and competitive technology. Generative AI content generation was integrated into the product before ChatGPT's release. The current stack exposes a REST signal API (search, enrich, filter; sub-200ms responses), batch delivery to GCS, real-time email verification using SMTP handshake, MX validation and AI catch-all detection, and an npm-distributed MCP server for LLM agents. The company reports 3.8B+ signals processed and SOC 2 Type II auditing and GDPR compliance.
Go-to-market
Self-serve sign-up with 1,000 free credits and low-priced entry credit packs, a developer-facing motion (API reference, SDKs, MCP server, quickstart docs) aimed at builders using tools such as Claude Code, AI SDRs and n8n, plus a sales-led enterprise track for custom volume, flat-file licensing and OEM embedding. Distribution historically ran through a free Chrome extension and marketplace presence, including the HubSpot marketplace, alongside integrations with major CRMs, sequencers and inboxes.
Enterprise go-to-market and sales development teams, B2B data platforms and sales-intelligence vendors licensing data via OEM, and developers building AI SDRs, agents, and automation workflows. Early adoption came from sellers at 250+ companies including ZoomInfo, UserZoom, Outreach, Workato, SailPoint, OnTop, and GoLinks; cited customers and partners include RocketReach, TechTarget, Skuid, AiSDR, ZoomInfo, and 6sense.
Geography
Headquartered in San Francisco, California; the company opened an office in the SoMa district of San Francisco. Data delivery is via API and cloud file push, and the company states GDPR compliance.
History
Autobound started with an AngularJS prototype that attracted early users but could not support a multi-source signal platform; with an outsourced engineering partner it was rebuilt on Vue.js and Node.js with a new insights database, shipping an MVP six months into the rebuild and adding generative AI content generation ahead of ChatGPT's launch. Distribution moved into sellers' existing tools via a Chrome extension covering LinkedIn, Gmail, Outreach and Salesloft, then Autobound Anywhere for any website, along with HubSpot CRM and Salesforce integrations and a HubSpot marketplace listing. A $4M seed round led by Dundee VC followed. The product subsequently evolved from an email-writing assistant into B2B signal intelligence infrastructure covering 700+ signal types from 35+ sources, licensed via API, flat file and OEM.
Risks & controversies
An independent review reports that Autobound's generated copy often sounds generic without manual editing, that users have limited control over tone and structure, that pricing scales quickly for larger teams, and that the platform lacks LinkedIn automation and end-to-end prospecting, follow-up and meeting-booking capabilities, positioning it as an incomplete outbound system on its own. Several performance and customer-impact figures are self-reported by the company or by its development vendor rather than independently verified.
