Both are real AI SDRs.
Only one keeps going when email is ignored.
You've found two products that genuinely write, reply and book on their own — rarer than the category's noise suggests. The difference is what happens to the lead who never answers email or LinkedIn. On the right: that lead, in both.

AiSDR (2 channels)
Lead: Daniel Reyes, VP Ops — ignores email
Sellinger (7 channels)
Lead: Daniel Reyes, VP Ops — ignores email
AiSDR is a credible AI SDR on email and LinkedIn — the two most crowded channels in B2B — metered by researched contacts and sold demo-first. Sellinger works those two plus the five where people still answer — WhatsApp, voice, SMS, Instagram and your own website — answers what comes in as well as what goes out, lets conversations run uncapped, and proves itself on your leads for 30 days before asking for a card.

What you're really buying
Many bots send. You're paying for the one that books.
The reports in shadow are what a two-channel quota buys: contacts researched, sequences sent, a tidy number at month-end — and Daniel, consumed from the quota, never reached. Activity is easy to count. It isn't what you wanted.
The diary in the lamplight is Sellinger's side: the lead followed to the channel he actually answers, everyone who writes to you answered at any hour, existing customers kept warm, and the slot written in. Your part is turning up on Friday at 14:00.
It Hunts. It Answers. It Remembers.
Two channels of outbound is a start. The agent runs the whole desk.
It hunts
Writes and sends per lead on email and LinkedIn like AiSDR does — then keeps going where AiSDR stops: WhatsApp, a real voice call, SMS. Daniel above wasn't uninterested. He was unreachable on two channels.
It answers
Replies in minutes on every channel — and answers the people who come to you: website chat at 23:00, the inbound call, the Instagram DM. An outbound-only SDR leaves your front door unstaffed.
It remembers
The lead who said 'Q4', the customer with a renewal next month, the thread that went quiet on LinkedIn and revived on WhatsApp — one memory across seven channels, for new leads and existing customers alike.
Seven channels out, every channel in, every customer remembered — for about five minutes of your attention a day.
What the Money Buys
Both verified August 20, 2026. One meters contacts; the other prices the channel and lets conversations run.

From a Founder Who Tried the Category
Real customer, real footage.
“Sellinger replaced our entire SDR team and tripled our pipeline in 3 months.”
Garrett Noach — Founder, Lamothermic. A manufacturing business, not a tech company — he judged it the only way that counts: by what landed on the calendar. Press play.
A note from Mr. Sellinger
The gentleman who runs your desk
I respect AiSDR — it is the real thing, and there are few of us. But I'd gently point out that I also pick up your phone, answer your website at midnight, and follow Daniel to WhatsApp when he ignores his inbox. Seven doors, both directions.
And I don't ask for a demo before I'm allowed to prove it. Thirty days on your leads, free. Keep whichever books more.
— Mr. Sellinger
