Last updated: June 2026

Choose Prosp if...

  • →You're ok paying $79 per month for each LinkedIn account you connect, and paying that again every time you add a seat.
  • →You only need LinkedIn outreach and have no near-term plan to add email or WhatsApp sequencing.
  • →You're fine with outreach personalization that pulls from LinkedIn activity and website scraping, without a social listening layer behind it.
  • →You don't need a GTM strategy dashboard and are comfortable building targeting criteria yourself.
  • →You're comfortable handling targeting, copywriting, and campaign strategy yourself, since Prosp doesn't offer an option of a dedicated resource running the show for you.

Choose Heddl if...

  • →You want LinkedIn, email, and WhatsApp running from one sequence instead of paying per channel tool.
  • →You want to start at $30 in credits instead of committing to a $79-per-seat monthly plan before you've tested reply rates.
  • →You want social listening across 9 platforms to catch buying signals before you write a single message.
  • →You want a managed option where a dedicated GTM Engineer runs outreach for you, not just software you operate yourself.
  • →You want ICP scoring built into the platform instead of relying on manual lead-list judgment.

Prosp built a focused LinkedIn automation tool with strong personalization mechanics. Heddl built a wider GTM platform that starts with market signals and ends with a closed deal. Picking between them comes down to channel scope and how much of your stack you want consolidated.

How Does Heddl Compare to Prosp on Features?

Heddl runs LinkedIn, email, and WhatsApp from one sequence with built-in ICP scoring and social listening. Prosp runs LinkedIn only, with AI voice notes and website-scraping personalization as its core differentiators.

Both tools automate connection requests, DMs, and InMails with AI-personalized copy, and both rotate multiple LinkedIn accounts behind proxies to manage daily sending limits safely. Where they diverge is scope. Prosp's standout feature is voice note personalization, audio messages recorded in a cloned voice and customized per lead, which reportedly lifts reply rates and which Heddl does not currently offer. Prosp also runs an AI web scraper that visits a prospect's site and pulls specific details into outreach copy, similar in spirit to Heddl's signal-based personalization but scoped to a single lookup rather than continuous monitoring.

Heddl's standout sits upstream of outreach itself: social listening across nine platforms, including LinkedIn, Reddit, X, Instagram, TikTok, YouTube, G2, Capterra, and Trustpilot, feeds an ICP scoring engine that rates leads 3 to 10 before a message ever goes out. Prosp has no equivalent signal layer; targeting depends on the lists and search criteria a user builds manually inside LinkedIn Sales Navigator or its lead finder. Email and WhatsApp also sit inside Heddl's core sequence builder as native channels, while Prosp's email capability runs through separate tool integrations rather than a built-in send channel. For a team that wants one signal-to-send workflow instead of stitching LinkedIn data into a separate email tool, that structural difference matters more than either tool's individual automation quality.

How Does Heddl Pricing Compare to Prosp?

Prosp charges per LinkedIn account starting at $79 a month, dropping to $49 with an annual commitment. Heddl starts at $30 in pay-as-you-go credits with no per-seat structure, or $500 a month for a fully managed service.

Prosp's pricing scales directly with the number of LinkedIn accounts connected. A solo operator pays $79 a month on the monthly plan or $49 a month on annual billing; an agency running outreach across five client LinkedIn profiles multiplies that same per-seat fee five times over, before counting any separate email tool needed to round out the channel mix. Heddl's pay-as-you-go model starts at $30 in credits covering LinkedIn, email, and WhatsApp sequencing together, with no forced subscription, no seat count, and no minimum monthly spend to maintain access. For teams that want outreach run for them rather than operated in-house, Heddl's Managed tier at $500 a month includes a dedicated GTM Engineer, ICP-focused lead generation, sequence copywriting, and daily and weekly reporting. A comparable outcome on Prosp would mean paying per-seat licensing fees and separately hiring or contracting someone to define targeting and write copy, since a packaged managed service is not part of what Prosp offers today.

Who Should Use Heddl vs Prosp?

Prosp fits teams that have already settled on LinkedIn as their only outbound channel and want strong AI personalization, including voice notes, within that one channel. Heddl fits teams that want LinkedIn plus other channels, signal-based targeting, or a managed alternative to hiring in-house.

A solo founder doing their own LinkedIn outreach with no near-term plan to add email or WhatsApp might find Prosp's focused tooling and voice note differentiator sufficient for the job. An SDR squad running coordinated sequences across LinkedIn and email at the same time needs a platform that natively supports both without a manual handoff between tools, which points more directly toward Heddl. A GTM agency managing outreach across many client accounts faces per-seat costs on Prosp that scale linearly with every new account added, while Heddl's multi-workspace architecture and optional managed tier offer a different cost and operating structure for that same scaling problem, particularly once a client roster grows past a handful of accounts.

“Most teams don't choose a six-tool stack on purpose. It happens one point solution at a time, and the cost shows up later in seat fees and context switching.” — Rajiv Mukherjee, Founder, Heddl

Prosp is a capable LinkedIn-only automation tool with genuinely differentiated personalization mechanics, particularly its voice notes. Heddl is built for teams that want LinkedIn alongside email and WhatsApp, signal-based targeting, and the option to hand the whole motion to a managed team. Compare your channel needs and seat count against both pricing models before deciding.

Frequently Asked Questions

It depends on channel needs. Prosp focuses entirely on LinkedIn automation with AI voice notes and website-scraping personalization. Heddl covers LinkedIn, email, and WhatsApp in one workflow, plus social listening and ICP scoring upstream of outreach. Teams needing only LinkedIn may prefer Prosp's focused toolset; teams wanting broader channel coverage or signal-based targeting tend to fit Heddl better.
Heddl's pay-as-you-go credits start at $30 with no per-seat fee. Prosp charges $79 per month per connected LinkedIn account on its monthly plan, or $49 per month with an annual commitment. For a single LinkedIn seat, Prosp's annual plan can be close in cost; for multiple accounts or added channels, Heddl's flat credit model scales differently than Prosp's per-seat structure.
Yes. Heddl does offer the option of sending voices notes over campaigns. However, voice note personalization (sending automated audio messages in a cloned voice) is a specific Prosp feature that Heddl does not currently offer.
Yes. Switching means moving LinkedIn sequences and connected accounts into Heddl's outreach engine, which also supports adding email and WhatsApp sequencing that Prosp does not natively offer. Existing LinkedIn campaign logic and messaging can generally be rebuilt inside Heddl's sequence builder.
For LinkedIn automation specifically, yes. Heddl covers connection requests, DMs, InMails, and multi-account rotation the same way Prosp does. The one feature gap is AI voice notes, which Heddl does not currently support. Teams relying heavily on voice note outreach should weigh that gap before switching.
Yes, in scope. Prosp is built specifically for LinkedIn outreach. Heddl adds email and WhatsApp sequencing, social listening across nine platforms, an AI GTM strategy dashboard, and ICP scoring, none of which Prosp offers natively.
Prosp does support multi-account management with proxies for agencies running several client LinkedIn profiles, but each account adds another $79 (or $49 annual) seat fee. Heddl's multi-workspace architecture also serves agencies, with a managed tier option for agencies that want outreach run rather than operated.
Heddl, because it natively runs LinkedIn and email from the same sequence builder. Prosp's core product is LinkedIn-only, so a team also running email would need a separate tool and integration to connect the two, adding cost and complexity Heddl avoids by default.
Email and WhatsApp as native channels, social listening across nine platforms, an AI GTM strategy dashboard, built-in ICP scoring, and a managed service tier with a dedicated GTM Engineer. Prosp's product is scoped to LinkedIn automation and does not include any of these.
AI Voice note outreach, automated audio messages recorded in a cloned voice and personalized per lead. This is Prosp's signature differentiator and is not currently available on Heddl.
Prosp competes most directly with other LinkedIn-only tools like HeyReach, Waalaxy, and Dripify, and its voice note feature sets it apart in that category. Against Heddl specifically, the comparison is less about LinkedIn mechanics and more about whether a team needs channels and signal data beyond LinkedIn, which Prosp does not provide.
Existing LinkedIn account history and warmup are tied to the LinkedIn account itself, not to Prosp, so connecting the same accounts to Heddl does not reset warmup. Campaign sequences and messaging logic do need to be rebuilt inside Heddl's sequence builder.
