Apollo.io vs OnceHub

Apollo.io is a sales intelligence and engagement platform from San Francisco that combines a B2B database of more than 270 million contacts and tens of millions of companies with the tools to reach them. Many startups use it as their prospecting data source, outbound tool and, at first, a lightweight CRM, all in one subscription.

Prospecting starts with filters for title, seniority, industry, headcount, technologies, funding and buying intent, and a Chrome extension surfaces emails and phone numbers on LinkedIn and company websites. Contacts flow into sequences that mix automated emails, call tasks and LinkedIn steps, with a built-in dialer, call recording, meeting scheduler, enrichment of existing CRM records and AI that researches accounts and drafts personalized messages. Usage runs on credits for emails, mobile numbers and exports. The free plan is unusually generous for a data vendor, and paid plans are priced per user per month, rising through Basic and Professional tiers to a Custom plan for larger teams.

Apollo fits startups, SMB sales teams and founders doing outbound who need data and sequencing at a fraction of ZoomInfo's price. Email accuracy is generally good, mobile numbers are weaker, and teams must manage sending limits and domain health to protect deliverability. ZoomInfo offers deeper enterprise data, Clay is better for multi-source enrichment and research workflows, and Instantly or lemlist focus on outreach volume and personalization. Coverage of Turkish companies exists but is thinner than for the US and Western Europe.

OnceHub is a meeting scheduling and inbound engagement platform for sales, support and service teams. The company started in 2006 as ScheduleOnce, founded by brothers Rami and Gilad Goraly, grew without outside funding, and renamed itself OnceHub in 2019 when it moved from a single booking tool to a broader lead engagement suite. Its core job is turning a website visit or form fill into a booked meeting with the right person.

The product covers booking pages for single hosts, panels and group sessions, routing forms that qualify leads and assign them by rules, round robin and maximum-availability distribution, room scheduling, and chatbots that can hand a visitor to live chat or an instant meeting. Plans stack: a free Basic plan for one user, then Schedule, Route and Engage, each adding a layer (CRM sync and payments, then routing, then chatbots), with an Enterprise tier for 30+ users.

OnceHub fits revenue teams that want scheduling and routing in one place without paying Chili Piper prices, and regulated organizations that need a security add-on and custom agreements. The interface is busier than Calendly, which is easier for solo users and simple team links, and SavvyCal feels more polished for personal scheduling. Chili Piper remains deeper for complex Salesforce routing at large companies.

In 2026 OnceHub added AI phone and web agents for guests and an MCP integration that lets hosts manage their setup from an AI chat client. Buying tip: start on the 14-day Engage trial, then drop to Route if you do not need chatbots; annual billing saves up to 18%.
