AiSDR is an AI SDR bought to write and send email at volume. Cafiyn FlyWheel runs the whole acquisition loop, priced in Wheels, straight SaaS from $29/mo.
AiSDR belongs to the AI SDR category: software that researches a prospect, writes something that sounds like it was written for them, and sends it, at a volume no human rep would sustain. It is bought by teams who already know who they are selling to and want the typing and the follow-up taken off a person's desk. The agent is centered on autonomy, you point it at a list and it works.
Cafiyn FlyWheel is a narrower promise and a wider job. It sources verified prospects against your ICP, researches each account, runs deliverability-managed personalized email, handles the replies, and then writes what happened back to the Blueprint, the shared context layer both Cafiyn products read from. The next round is aimed by the last one.
People compare the two because both end in email arriving. The real difference is who decides what gets sent, and whether that decision gets better over time.

*Straight SaaS pricing: Cafiyn FlyWheel is $29 Ignition, $49 Trajectory, $99 Orbit, or $199 Command per month, priced in Wheels (1 Wheel = 1 target account through the full workflow). No revenue share. See full pricing.
Feature availability, pricing, and timelines reflect publicly available information at the time of comparison and may change. Time-to-meeting and time-to-revenue figures are indicative, not guarantees; results depend on product quality, market demand, pricing, and audience.
The honest split: AiSDR is the better buy when your targeting is settled and the constraint is output. It is a product your team runs, the sending account stays yours, and nobody has to approve you first. Cafiyn FlyWheel is the better buy when the constraint is knowing which accounts deserve the email at all, and when you would rather one loop own sourcing, research, sending, replies, and the feedback into the next round than assemble that yourself.
Two things we would rather you hear from us than discover later. Managed does not mean a named human on every plan: the workflow is run for you from Ignition at $29 a month, while priority routing and a dedicated account manager arrive at Command. And the market and demand work is not part of FlyWheel at all: it sits in Cafiyn Lens, a separate module from $14.99 a month, optional at every FlyWheel tier.
One last caveat: FlyWheel is not purchasable today. Entry is an application-reviewed waitlist, and pricing is straight SaaS in Wheels from $29 a month, with no revenue share and no bundle discount. See pricing. If you need something running this week, take AiSDR and revisit us later.
Yes, if what you need is the whole loop rather than a faster sender. AiSDR is bought to research prospects and put personalized email out at volume, from an account your own team runs. Cafiyn FlyWheel sources the accounts, researches them, runs deliverability-managed email, handles replies, and writes outcomes back so the next round targets better. If the sending is the only part you want, AiSDR is the simpler buy, and it is the one you can act on sooner: entry to Cafiyn is an application-reviewed waitlist.
Probably not. Sourcing, enrichment, research, personalized email, and reply handling all sit inside the same FlyWheel workflow, so a second sending agent mostly duplicates it. Some teams do keep an AI SDR alongside for inbound speed to lead while FlyWheel runs the outbound loop. That is a real pattern rather than a contradiction, but it is two subscriptions doing adjacent jobs, so decide which one owns the sending domain.
The shapes differ more than the numbers. AI SDR platforms like AiSDR are typically sold on a monthly plan sized by sends or contacts, so cost tracks how much email leaves. Cafiyn FlyWheel is straight SaaS priced in Wheels, where one Wheel is one target account taken through the full workflow: Ignition $29, Trajectory $49, Orbit $99, Command $199 per month, with Enterprise quoted. Cafiyn Lens, the market and demand assessment module, is priced separately from $14.99 a month and stays optional at every tier. No revenue share, no bundle discount. The only discount is annual billing at 20 percent off.
Email on every FlyWheel tier, managed for deliverability end to end. LinkedIn is signals and research rather than sending, and it arrives at Command and Enterprise. Phone and social channels are Enterprise only. That is narrower than the multichannel story some AI SDR products tell, and deliberately so: one channel run properly beats four run thinly. If you need automated LinkedIn or dialer sending on a small plan, look elsewhere.
One product, one predictable bill. Straight SaaS from $29/mo, priced in Wheels. No revenue share, no retainer, cancel anytime.
