I've spent the last year competing against most of these tools, which means I've studied them harder than I'd like to admit. These are the nine that actually matter in 2026.
How I ranked them
One question decided the order. How far does the tool get you, on its own, from "here's my website" to "a real person replied and wants to talk"?
The tools at the top do the whole run. They find the buyers, research them, write the message, send it across channels, and learn from what happens. The tools lower down do one piece of that really well and leave the rest to you.
Lower doesn't mean bad. Instantly is great at what it does. It just isn't going to find your customers for you.
Prices below come from public pricing pages and third-party reviews as of September 2026. They move a lot in this category, so check before you buy.

- Chronos
You give Chronos your website. It figures out who your customer is, finds those people, researches each one, and starts talking to them in your voice. LinkedIn, email, X, Reddit and Instagram all run from the same place.
The part I care most about is that you run it in plain English. You type "find 200 seed-stage fintech founders and start a LinkedIn and email sequence" and it does that. No sequence builder. No workflow canvas. If you already live in an AI agent, you can plug it in over MCP and drive Chronos from there.
Every send teaches it something. Replies, ignores and objections feed back into who it targets next and what it says. So the campaign in week six is sharper than the one in week one, without you rewriting anything.
It connects to Salesforce, HubSpot, Outreach, Apollo and Sales Navigator if you have them. You don't need any of them to start. Chronos says more than 3,000 companies use it.
Pricing: the browser app is free to start, with a Pro plan on top. Managed GTM and Enterprise plans are custom.
The honest downsides. It's younger than Apollo or Clay, so there's less community content around it. Team plans aren't list-priced, which I know some people hate. And channels like Reddit reward restraint. The tool will do what you ask, so ask for something a community would actually welcome.
Best for: founders and small teams who want the whole outbound motion running without hiring for it.
- Artisan (Ava)
Artisan is the company behind the "Stop Hiring Humans" billboards, and Ava is its AI BDR. It pulls leads from its own database of 300M+ contacts, enriches them, writes personalized email, and handles deliverability for you.
The big 2026 change was Ava 2.0. Reviewers report it cut entry pricing roughly tenfold and opened self-serve signup for the first time. That makes it a real option for smaller teams now, not just funded sales orgs.
The catch is focus. Ava is built around email. It also had a brief LinkedIn ban in December 2025 over scraped data and trademark issues, which got resolved within weeks. That's less a knock on Artisan and more a reminder that every tool here depends on platforms that can pull access overnight.
Best for: teams whose buyers live in their inbox and who want a proven, well-funded vendor.
- 11x (Alice)
11x sells named AI workers. Alice runs outbound across email and LinkedIn, and Julian handles phone calls. It's one of the most autonomous products on this list. You set the ICP and review the meetings.
It's also one of the most expensive. The Growth plan starts at $3,750 a month billed annually, so roughly $45K a year. Reviewers regularly mention setup time, deliverability tuning and CRM sync as things you'll have to babysit. The company also went through a CEO change in 2025 after public questions about its customer claims.
Best for: mid-market sales teams with budget and a clear outbound quota to hit.
- Clay
Clay is the power tool. It's a spreadsheet that can pull from 150+ data providers, run AI research on every row, and push the result anywhere. Growth teams build incredible things in it.
The word to notice is "build." Clay doesn't send anything by itself. You still need a sending tool, usually a Sales Navigator seat, and someone who enjoys wiring workflows. Pricing moved in March 2026 to a two-meter model of Data Credits and Actions. Launch is $185 a month and Growth is $495. Credit burn is where surprise bills come from.
Best for: technical operators who want total control and have the time to use it.
- Valley
Valley does one thing thoughtfully. It watches LinkedIn for warm signals like profile views, post engagement and competitor followers, scores those people against your ICP, and writes to them in your voice. It added native email in August 2026.
Starts at $149 per seat a month. If LinkedIn is your main channel and you care about reply quality over volume, it's a strong pick. If your buyers aren't on LinkedIn much, it has less to work with.
Best for: B2B founders who sell to people who post.
- AiSDR
AiSDR is the lean, quick-to-launch option. A Y Combinator company with an agent that covers both inbound and outbound. Plans run $250, $900 and $2,500 a month.
Reviewers like the clear pricing and fast setup. They're less excited about message depth and enterprise controls. It's a sensible first AI SDR if you want to test the idea without a big contract.
Best for: small teams who want to try an AI SDR this week.
- Apollo
Apollo is where most people start. Huge contact database, email sequences, a Chrome extension, and a free plan that's actually usable. Paid plans run $49 to $119 per user a month on annual billing.
It's a tool, not an agent. A human still decides who to contact and what to say. Apollo also pulled its LinkedIn automation in early 2026, so it's mostly an email and data play now. Watch the auto-renew terms too. You need to cancel 30 days before renewal.
Best for: anyone who needs contact data and basic sequences on a budget.
- HeyReach
HeyReach is LinkedIn automation built for agencies. Its trick is running many LinkedIn sender accounts from one dashboard, which lets you spread volume across profiles. $79 per sender a month, or $999 for the agency tier.
It's volume-first. Personalization is mostly templates, and email hands off to a separate tool. LinkedIn also removed HeyReach's own company page in March 2026, which is worth weighing if your account matters to you.
Best for: agencies running LinkedIn campaigns for many clients.
- Instantly
Instantly is the best-loved cold email sender out there, with thousands of positive G2 reviews. It handles inbox rotation, warmup and sending at scale, from under $50 a month.
It ranks last here only because of how I ranked. It sends what you give it to the list you give it. Finding the right people and writing to them well is still your job, plus managing domains and inboxes.
Best for: people who already know exactly who to email and just need volume.
Chronos vs the others, straight answers
People ask me these constantly, so here they are in one place.
Chronos vs Clay
Clay gives you the parts. Chronos gives you the finished machine. With Clay you build the enrichment workflow, then bring your own sending tool. With Chronos you describe what you want and it researches and sends. Pick Clay if you love building. Pick Chronos if you want the result.
Chronos vs Artisan
Both are AI agents that do outbound for you. Artisan is focused on email and has a big contact database. Chronos runs email plus LinkedIn, X, Reddit and Instagram from one command, and it's free to start.
Chronos vs 11x
11x is built for mid-market sales teams on annual contracts starting around $45K a year. Chronos is built so a solo founder can start free today and grow into a managed plan later.
Chronos vs Valley
Valley goes deep on LinkedIn signals. Chronos covers LinkedIn too, but also reaches buyers who spend their time on X, Reddit or email. If LinkedIn is your only channel, Valley is a fair comparison. If it isn't, Chronos covers more ground.
Chronos vs Apollo
Apollo is a database and a sequencer that a person operates. Chronos is an agent that does the operating. They also work together, since Chronos can use Apollo as a data source.
Chronos vs HeyReach and Instantly
These are sending tools. They're great at volume once you know who to hit. Chronos decides who to hit and what to say, then sends. Plenty of teams are better off with a thoughtful agent than with more volume.
How to actually pick
Forget the feature grids for a second and answer three questions.
- Do you know exactly who your buyer is? If not, you need something that figures it out for you. That's the top of this list.
- Where does your buyer spend time? Email only is a different problem from LinkedIn, X and Reddit.
- How much of your week do you want to spend running this? Clay and Instantly reward hours. Agents give you those hours back.
My advice for most founders reading this on Indie Hackers: start with whatever is free and gets a real message to a real person this week. You'll learn more from ten honest replies than from a month of comparing tools.
Obviously I hope you try Chronos. If it's not the right fit, one of the other eight probably is. Either way, go talk to your customers.
