We work with our customers to reimagine the world of business communications and collaboration. This relentless passion to innovate has made us the #1 cloud communications provider worldwide, and we donโt plan on stopping there.
Technology breaks down barriers and unlocks potential, making it easy for people to do their best work together. In todayโs mobile world, this means giving teams, partners, and customers the ability to communicate, collaborate, and connect the way they want on any device, anywhere, anytime. It's what we call collaborative communications, and itโs at the heart of everything we do.
With our flexible, cost-effective cloud communications and collaboration solutions, weโve created the ideal workplace, where business can be done more efficiently and effectively. From an all-in-one cloud phone system with team messaging and video conferencing to a complete contact center and more, we build solutions for every business, no matter how big or small.
Apollo.io RingCentralRingCentral is particularly recommended for small to large businesses seeking an integrated communication and collaboration platform. It is ideal for companies with remote teams who require a reliable, unified system that supports mobile and desktop use. Additionally, businesses looking for advanced features like video conferencing, call center management, and CRM integrations will find RingCentral highly beneficial.
We use Apollo with our Sales and BDR team to manage our cold outreach. The strength of the platform is the sequences and cadences that you can set up. Compared to other tools we have used in the past like Salesloft the UI is much easier to navigate. The main limitation is that the quality of data isn't as vast and often I can find prospects on Linkedin but not in Apollo.
Based on our record, Apollo.io seems to be a lot more popular than RingCentral. While we know about 69 links to Apollo.io, we've tracked only 3 mentions of RingCentral.

Personal email domains destroy this. Clearbit's Enrichment API returns a null company when it hits gmail.com. Apollo routes personal domains straight to a consumer bucket and skips B2B fields entirely. Even PDL's /person/enrich endpoint โ the most permissive of the major providers โ gives you around 32% hit rate on Gmail addresses versus 74% on corporate domains. I measured this across 6,200 signups for a... - Source: dev.to / 3 months ago
A few things worth flagging: PDL beats Clearbit's historical rates for US and Western European companies, but drops to ~52% match rate for Japan and South Korea specifically. Apollo underperforms on raw company matching but returns significantly more contacts per domain in Prospector-style queries than Clearbit's Prospector ever did โ the tradeoff is more stale titles in the result set. Hunter.io is fast and cheap... - Source: dev.to / 3 months ago
One thing comparison guides consistently get wrong: Clay is not an enrichment API. It's a waterfall orchestration tool that calls People Data Labs, Apollo, Clearbit, and others in sequence for you. It's useful, but it adds 2โ8 seconds of latency per row in my runs and costs more per match than going direct. For a CRM webhook flow where you need sub-second enrichment calls, Clay is the wrong layer to hit first. - Source: dev.to / 3 months ago
Last year I ran the same LinkedIn Sales Navigator export through three enrichment APIs. Apollo matched 61% of the emails. Hunter.io matched 54%. An OSINT-first pipeline I'd built in n8n โ pulling from public sources before hitting any paid API โ matched 79% and cost roughly $0.003 per contact. The delta wasn't magic. It was sequence. - Source: dev.to / 3 months ago
Despite having its LinkedIn Page removed in 2025, Apollo remains a functional enrichment and outreach platform with 275M+ contacts. The free tier includes 10,000 credits and the $49/month basic plan is the cheapest entry point for a combined enrichment-plus-sequencing workflow. Apollo's data collection methods have attracted LinkedIn's attention, but the product continues to operate. The risk I'd assign it:... - Source: dev.to / 4 months ago
Systems like 8x8/RingCentral/Vonage or even Voip.ms might be ideal for you. Source: almost 5 years ago
I saw www.calltrackingmetrics.com ; ringcentral.com ; twilio.com ; Zadarma. At this moment it seems that calltrackingmetrics seems to be the first solution I would try because they put in front of their ads the fact to track with google ads. Twilio seems to be too much complex to use and they don't have an iPhone app ; ringcentral I don't know and Zadarma seems good. Source: about 5 years ago
I use unitelvoice.com. It works fine has an app and can forward to my cell number. Used to use ringcentral.com it was fine when it worked but support was crap. Source: over 5 years ago
