Comparison
Hellofew vs AiSDR
AiSDR describes itself as: “Finds in-market buyers using real-time signals, then reaches out with messages that sound like your best rep wrote them.”
Prices below were read from aisdr.com on 8 September 2026.
The short answer
- Buy AiSDR if
- you have a sales team, a CRM you live in, and you want email and LinkedIn run together at volume.
- Buy Hellofew if
- you are one founder who wants the whole loop run for you — research, targeting, writing, sending, replies — on the account you have spent years building, for $49 rather than $250.
Price
AiSDR starts at $250/mo. Hellofew is $49/month.

What AiSDR does better
Genuinely better, not faint praise. If any of these is what you need, buy theirs.
- Native two-way HubSpot and Salesforce sync, which we do not have at all.
- Email as a first-class channel with mailbox warm-up — we only do LinkedIn.
- Multi-seat and multi-account: 20 LinkedIn accounts on Scale, against our one.
- A dedicated GTM engineer for onboarding at the top tier.
Where we differ
- Entry plan is $250/mo — five times ours.
- Explore and Scale are quarterly contracts, not month to month.
- Contacts are metered: 200/month on Solo, so the cap is on research volume rather than on sending safety.
The thing AiSDR's pricing page does not mention
A daily sending limit. Neither does anyone else's in this category — we checked all four on 8 September 2026 for any mention of invitation caps, warm-up ramps, or what happens if LinkedIn objects to your account.
That absence is not an oversight, it is the business model. Volume demos well. But LinkedIn does not publish its limits, restricts accounts that exceed them, and the account it restricts is yours — not your vendor's.
So here is our whole spec, in public
- 20 invitations a day, maximum. You cannot raise it. Neither can we — it is a constant in the code, not a setting.
- A new account starts at five a day and takes three weeks to reach the ceiling.
- Nothing sends outside your working hours, and we stay twenty minutes clear of both ends. Weekends and public holidays are skipped.
- Gaps between sends are irregular by design. Twenty invitations exactly three minutes apart is more obviously scripted than twenty at random times.
- An account with fewer than 150 connections is held back and sends nothing at all.
- One follow-up. Not five. Any reply cancels everything still queued for that person.
- If your acceptance rate falls below 15% we halve your caps; below 8% we stop inviting and tell you. A low accept rate is what precedes a restriction.
- Every message waits for you to approve it, individually, for ever — and the whole schedule is visible before any of it runs. Approving is the only way anything sends.
- If LinkedIn flags the account in its first 24 hours of sending, we stop and stay stopped until you say otherwise.
Hellofew does one thing: agents that run LinkedIn outbound end to end for a single founder — the research, the targeting, the writing, the sending and the replies — for $49/month. If what you want is a few hundred invitations a week, it is the wrong product and AiSDR is probably the right one. We would rather say that here than take your money and disappoint you.
Free to read what it writes about your market. $49/month when you connect LinkedIn and it starts finding real people.
