One database, sequencer and dialer for a founder who wants outbound without stitching tools together
The most complete solo outbound starter — as long as you accept that you are the SDR and Apollo is the engine, not the rep.
Real-time B2B contact search with verified emails and mobiles, sold on annual, quote-only licenses
The finder works, but quote-only annual pricing is the worst fit in this list for a solo founder who needs predictable monthly costs.

Seamless.AI is an outbound prospecting database, not inbound lead capture and not a full SDR. Its job is the top of the outbound workflow: search in real time for people and companies matching your buyer profile, reveal verified work emails and mobile numbers, watch job-change and buyer-intent signals, and use its Autopilot features to build and refresh prospect lists against criteria you set. A Chrome extension pulls contacts while you browse professional profiles and company sites. From there the workflow leaves Seamless: sequences are sent from your engagement tool, replies are handled by you or that tool, and meetings are booked through your calendar and CRM, which Seamless syncs to rather than replaces. For a solo founder the product itself is approachable — search, reveal, export — but the commercial terms are the opposite of solo-friendly, and this listing scores it on that honesty. Paid pricing is not published: the pricing page routes you to a sales quote, licenses are annual subscriptions, and cancelling requires action well before renewal because contracts auto-renew. Credits are also easy to misunderstand, with a small one-time free allowance and very different monthly allowances between the Basic and Pro licenses. A founder who needs predictable, month-to-month, self-serve costs should treat the missing price itself as the finding.
Pricing not published — quote only. Paid licenses are annual; only the free plan's $0 price and credit allowances are published.

Flat-fee cold email sending with unlimited mailboxes, plus a lead database sold on credits
Excellent value if cold email is your channel — budget for the bundle, not the $47 headline, plus domains and mailboxes.
Multichannel sequences across email, LinkedIn and calls, with warm-up and a built-in lead database
The best pick here if LinkedIn belongs in your sequence — just price the plan plus data credits together, not the headline alone.
