LoneScale
LoneScale is a data layer that lives inside Salesforce and HubSpot rather than in a separate app. It finds the right stakeholders at target accounts by persona, fills in emails and mobile numbers through a waterfall of more than 25 data vendors, enriches inbound leads from an email address, and keeps titles and firmographics current by rechecking them every 24 hours. It also tracks job changes, new hires and job postings, turning them into CRM updates, tasks and Slack alerts.
AI research agents qualify accounts and contacts using LoneScale's data, web search and site browsing, then write their findings and suggested openers into CRM fields, and a job title classifier sorts titles into departments and seniority. Field mappings can replace values or fill only empty fields, records match on CRM IDs or domains, and a mapping preview and per record log show what will be written. A Slack assistant, a Chrome extension, an API, a command line tool and an MCP server sit alongside native connections to Salesforce, HubSpot, Pipedrive, Sellsy, Attio, Clay, Make, Zapier and n8n.
Plans start with 100 free credits, then $200 a month for 2,000 credits on Starter and $1,000 a month for 20,000 on Growth, which adds job posting signals, with unlimited users, a 20 percent annual discount and custom Enterprise pricing. Paid plans start through a demo rather than a card checkout. LoneScale is run by LoneLine SAS, a French company founded in 2020, and sells to mid market teams in North America and Europe, with case studies from Tomorro, Greenly, Welcome to the Jungle and Elba Security.

AI research agents qualify accounts, contacts and signals with LoneScale's data, web search and site browsing, then write summaries and suggested openers into CRM fields, and a classifier sorts job titles into departments and seniority with a claimed 99.9 percent accuracy. The core of the product is enrichment, stakeholder sourcing and job change data, which work without the agents, and a native OpenAI connection runs on the customer's own key.
Workflows start as soon as they are created and run once or on a schedule, titles and firmographics are rechecked every 24 hours, tracked lists are enriched again monthly and agents fire on lists, schedules or inbound signals. Each field mapping is set to replace or to fill only empty values, records match on CRM IDs, domains or set criteria with idempotency keys against double writes, and a read only preview and per record log show what is written. The Slack app writes only when a rep clicks, but rollback and approval steps for scheduled runs are not described.
No model is named for the agents, the Slack assistant or the classifier, and how agents reach their conclusions is not explained. OpenAI appears only as an integration that runs on the customer's own key.
Tomorro reports $1.5 million in pipeline over its first nine months and more than 150 influenced deals, with a lower summary figure of $500,000 and 100 deals, and Greenly attributes 48 percent of its pipeline to hiring, job posting and job change signals. Two further case studies carry no figures, and headline claims such as 30 hours saved per rep a month, 70 percent better data quality and tenfold ROI in six months have no stated basis.
The terms make the customer responsible for collecting and processing personal data and for local prospecting rules, and the DPA leaves the legal basis to the customer. A do not sell form asks only for contact details and describes no process, timeframe or suppression, and no data broker registration or Do Not Call handling is described, even though the terms list automatic sending of prospecting emails among the functions.
Privacy terms take the form of a DPA, which names AWS as the only subprocessor without a location, marks transfers as not applicable, promises breach notice without a timeframe and keeps prospect data for three years. No privacy notice speaks to the people in the data beyond calling the source personal data freely available on the internet.
Contacts come from a waterfall of more than 25 vendors, with FullEnrich, Waterfall.io and Apollo named, ZoomInfo and Lusha connected as integrations and customers able to bring their own vendor keys, while funding data is drawn from Crunchbase. Source counts run from 15 to more than 30, and emails can come back marked as predicted, meaning an unverified pattern guess.
The Chrome extension uses no automation and never uses the rep's session to collect data, by LoneScale's account. LinkedIn profile links are the strongest matching input, and LoneScale can retrieve missing LinkedIn links and work history without saying how. LinkedIn's terms are not addressed.
Whether customer CRM data trains models is not addressed. Prospect data is kept for three years from collection, contracts for five years and invoices for ten, data is fully erased after the reversibility period apart from anonymous statistics, and integrations use OAuth without storing third party credentials.
The terms list automatic sending of prospecting emails among the product's functions, and AI written messages are pushed into cadence tools. No disclosure to recipients, notice to the people in the data or position on Article 50 of the EU AI Act is described.
Salesforce enrichment covers leads, contacts and accounts through page layout buttons, a custom intent object and a sandbox on request, and HubSpot covers contacts, companies, tasks, lists, deals and custom objects through a marketplace app. Pipedrive, Sellsy, Attio, Clay, Make, Zapier, n8n and a Slack assistant connect alongside, and the API syncs records with mapping rules, matching criteria and idempotency keys at 100 records per call, though its webhooks carry no signature. An MCP server with OAuth and eleven tools and a command line tool round out access for AI assistants.
The service runs in AWS data centers with no region stated, and data coverage is described as North America and Europe. No residency options are offered.
LoneScale holds SOC 2 Type 2, with no auditor, date or report route given, alongside an annual third party penetration test, private networks and firewalls, hashed passwords, two factor sign in, intrusion detection and backups. A trust center sits at trust.lonescale.com, while ISO 27001, encryption details and single sign on are not listed.
A free plan gives 100 credits without a card, Starter costs $200 a month for 2,000 credits, about 2,000 emails, 220 mobiles or 1,000 contacts, and Growth costs $1,000 a month for 20,000 credits at a lower rate with job posting signals. Every plan includes unlimited users, annual billing saves 20 percent and Enterprise is custom with a dedicated Slack channel, success manager and SLA. Paid plans start through a demo rather than a card checkout.
There is no fixed term, and a subscription can be cancelled at any time with effect at the end of the following calendar month, with fees not refundable. Data can be exported only until the subscription ends, rights to enriched records after that are not stated, and data is then erased apart from anonymous statistics. French law and Paris courts govern, and liability is capped at twelve months of fees.
Email results are labeled valid, catch all, invalid, unknown or predicted, the last being an unverified pattern guess, and phone verification requires special access. Accuracy above 90 percent is promised and even guaranteed, while the terms disclaim any guarantee not written into them, and no verification method or bounce refund is described.
Mid market sales, marketing and operations teams in North America and Europe are the focus. Case studies cover Tomorro, Greenly, Welcome to the Jungle and Elba Security, and the HubSpot app has more than 90 installs.
