    Apollo for automated outreach

    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.

    ๐Ÿ Competitors: SalesLoft
    ๐Ÿ‘ Pros:    Creating email sequences|Ab testing of emails|Good user experience
    ๐Ÿ‘Ž Cons:    Data quality is lacking sometimes|Onboardin process was cumbersome

  • GrapheneOS โ€“ Break Free from Android and iOS
    I can add certificates on my unrooted android. That how HTTPToolkit [0] works, it only requires adb, which (thankfully) doesn't trip banking apps. Banking apps can (and do iirc) pin certificates, so a rooted phone adds no risk whatsoever. Also in my experience a rooted phone experience is by far more secure than the OEM androids. Security is supposed to assess risk objectively, yet "running on a Xiaomi phone with... - Source: Hacker News / 6 months ago
  • Charles Proxy
    For my rather simple needs I've been using https://httptoolkit.com free edition, I like that it launches a independent Firefox window on its own for the intercepting so I don't have to touch my working browser or deal with configuring a proxy anywhere. - Source: Hacker News / 8 months ago

    This one is truly a gem: https://httptoolkit.com It even bypasses SSL pinning on Android using 1 click. - Source: Hacker News / 8 months ago
  • APKLab: Android Reverse-Engineering Workbench for VS Code
    Https://httptoolkit.com also worth a look if you're interested in this space: has some neat automated setup for Android MITM that can be much simpler _and_ more effective than the manual config route (with automated Frida setup on rooted devices, so it handles unpinning too!). More UI & less CLI focused, so depends which way your preferences go there. - Source: Hacker News / about 1 year ago

  • Enriching Free Trial Signups: The PLG Data Stack for Turning Inbound Users Into Qualified Pipeline
    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
  • Clearbit Is Now HubSpot-Only: A 1-to-1 API Migration Map for Teams Getting Locked Out
    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
  • Auto-Enriching Your CRM on New Contact Creation: A No-Code Webhook Playbook
    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 2โ€“8 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 / 4 months ago
  • How to Build an OSINT-Powered B2B Prospecting Workflow in 2026 (Without Getting Banned)
    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 / 4 months ago
