Three of the five platforms on this list changed owner, name, or shape in the twelve months to August 2026. Salesloft is now half of a merged company. Outreach moved its site from outreach.io to outreach.ai and repackaged its tiers around AI credits. Regie.ai folded its products into one platform and started publishing seat prices. A shortlist assembled from a 2025 comparison will send you into a sales cycle quoting SKUs that no longer exist.
The question that separates these five in 2026 is no longer sequence depth — every platform here branches on opens, clicks, and replies. It is who owns the layer above the sequence, and whether anything outside the vendor can reach the data underneath it. That splits the category three ways: incumbents bolting agents onto the sequencer, a merged company selling execution and forecast on one contract, and AI-native challengers trying to replace the engagement layer rather than extend it.
One note on ordering: the rank below is category fit, not our score. Default scores highest of the five at 8.1 and ranks fifth, because it does a different job well.
1. Outreach — the enterprise default, now sold as an agent platform
Outreach is still the platform for outbound orgs past roughly 100 reps: branching sequence logic, a dialer, Kaia conversation intelligence, deal management over the CRM, the deepest Salesforce integration in the category, and an admin surface that survives a reorg. The Spring 2026 relaunch put an agent layer on top of that. Outreach Omni is a conversational agent in Slack and mobile that answers deal questions and drafts email in one thread; Agent Studio lets RevOps build and schedule custom agents on a visual canvas; named agents cover meeting prep, coaching, and a Deal Agent that writes suggested CRM field updates back for rep approval. ooligo score: 7.5.
Pricing is quote-gated and now has two meters instead of one. The pricing page lists four Amplify tiers separated by AI credit allowance — Essentials at 10,000 credits, Core at 25,000, Plus at 50,000, Pro at 100,000 — with API call ceilings, custom object counts, and knowledge storage scaling alongside. No rate is published. Third-party estimates put core Engage seats around $100–140/seat/month on annual terms and the Amplify tiers roughly $100 / $130 / $160. Implementation runs $5,000–25,000+, and seat minimums of 25–50 are the practical floor.
Model the credit meter before you sign. Buying an agent tier and running out of credits in month four is the 2026 version of buying seats nobody logs into.
What it replaces: Salesloft at the upper end, and the RevOps scripts that reconstruct step-level reply rates by hand.
Where to start: run a 60-day pilot on one team with the agents switched on, and count credits consumed per rep per week. That number, annualized, is your real quote.
2. Clari + Salesloft — execution and forecast on one contract, and the only real agent reach
Clari closed its acquisition of Salesloft on December 3, 2025, creating a company of roughly $450M combined ARR across 5,000+ customers. Cadences, dialer, Conversation Intelligence (GA July 2026), Deals, and Clari’s forecasting layer now sit under one contract. If your shortlist was Outreach plus Clari on two agreements, one agreement covers both jobs. ooligo score: 7.5.
The reason to look here first is the Salesloft MCP Server, launched April 2026 and expanded through the summer. It exposes cadence and activity execution data, Clari Copilot call intelligence, forecast and deal-inspection data, and pipeline progression — with write-back, so an agent can take an action rather than only read. As of July 2026 it is listed natively in Claude’s connector directory. Outreach has shipped nothing comparable.
Two things to price in honestly. Product overlap: Clari acquired Groove in August 2023 and Wingman in 2022, so the merged company now owns two sales engagement products and two conversation intelligence products over one forecasting engine. Ask in the first call which of those is the strategic line and which is in maintenance, and get the answer in the contract. Integration drag: eight months past close, the two products still present as separate interfaces with no published joint roadmap, and buyers report the bundled configuration pricing above what the two standalone contracts did. Drift, which Salesloft bought in 2024, has been sunset; its conversational capability moved to 1mind.
Seat minimums start near 10–15 against Outreach’s 25–50 — the practical reason mid-market teams shortlist it first. Negotiated bands run ~$60–85/seat/month at 10–25 users and ~$110–160 at 75+. Vendr’s median annual contract across 703 purchases is ~$30,700 at an 18% average discount.
What it replaces: Outreach plus a separate forecasting vendor, and the BI dashboard someone built to join cadence activity to pipeline.
Where to start: connect the MCP server before you negotiate. Ten minutes of asking your own pipeline questions from an LLM tells you more about fit than a scripted demo.
3. Apollo — the SMB bundle, and the cheapest agent-reachable option here
Apollo compresses a 240M+ contact database, sequencing, a dialer, and enrichment into one contract at a price the incumbents cannot match: $49/seat/month (Basic, annual), $79 (Professional, adds dialer and AI assist), $119 (Organization, 3-seat minimum). A five-rep Professional team is $4,740/year in seats — roughly a seventh of Salesloft’s median contract. ooligo score: 7.8.
The 2026 change is the official MCP server, launched February 2026 at mcp.apollo.io/mcp with OAuth 2.0 and 29 documented actions across search, enrichment, contacts, accounts, lists, sequences, analytics, and tasks — included on every plan, free tier included, at no extra cost. It covers prospecting and sequencing; it does not expose deals, the dialer, or conversation intelligence, and its auth does not run headless.
That produces the surprise of this list: the cheapest platform on the page and the merged incumbent are the two an agent can actually drive. Outreach, RegieOne, and Default cannot be reached that way today.
Two costs sit above the sticker. Monthly billing runs 20–25% over annual, and mobile-number and bulk-export credits meter on every tier — the overage line is where Apollo earns its margin. Apollo acquired Pocus in March 2026 to add product-led scoring; none of it appears in the published tiers, so buy what ships in your contract term.
What it replaces: ZoomInfo plus Outreach plus a dialer, at roughly a third of the combined cost and a step down in data accuracy.
Where to start: run the free tier against 200 records in your actual ICP and measure match rate before paying for anything.
4. RegieOne (Regie.ai) — the one trying to replace the layer, not extend it
Regie.ai consolidated Co-Pilot and Auto-Pilot into RegieOne and now markets itself as an AI-native SEP: prospecting, sequencing, dialing, enrichment, and agents on one surface, with the explicit goal of collapsing the SEP line item rather than sitting beside it. Its stated target is a team running outbound on three tools — Salesforce, RegieOne, and LinkedIn Sales Navigator. Auto-Pilot agents source, research, and sequence continuously; Co-Pilot keeps a rep in the loop. ooligo score: 7.6.
Regie publishes rates now, a change from custom-only. AI SEP is $180/user/month with a 10-seat minimum — a ~$21,600/year floor covering sequencing agents, power dialer, AI messaging, and CRM integration. Force Multiplier Rep is $499/user/month with a 5-seat minimum — a ~$29,940/year floor — adding 120,000 AI and enrichment credits (about 1,000 accounts / 4,000 contacts), a parallel dialer up to nine lines, ten warmed mailboxes, and research agents.
The seat price is not the number to plan against. Credits carry the cost: data packages scale from Bronze (525K credits) to Platinum (6.08M), the parallel dialer is a $1,800/user/year add-on, and mailbox rotation runs $50–100/user/month. Vendr’s benchmark across 14 purchases puts the median buyer at ~$51,532/year — above either published floor, and the most expensive real number on this page.
What it replaces: the SEP, the dialer, and the enrichment contract, if the consolidation actually holds through year one.
Where to start: run Auto-Pilot on one segment against a human-only control group for a quarter, measuring meetings set rather than emails sent.
5. Default — the inbound half, and frequently the better marginal dollar
Default is not a sales engagement platform, and its fifth position understates it. It is the AI-native inbound platform: form, real-time enrichment, qualification, routing, and meeting booked on one workflow canvas, with routing rules described in natural language instead of maintained as branching field logic. ooligo score: 8.1 — the highest of the five.
It appears on this page because of a recurring buying mistake: upgrading the sequencer while inbound demo requests sit in a routing queue. Pricing is a platform fee plus seats plus enrichment credits — Growth at ~$500/month with 20K enrichment credits/year, $20 per scheduling seat and $45 per routing-and-scheduling seat with editor seats free; Scale at ~$600/month with 100K credits and website intent bundled in. Five AEs on routing plus two SDRs on scheduling is $765/month (~$9K/year); a mid-market deployment lands in the $15K–30K/year band. The trap is the credit pool — Growth’s 20K/year is ~1,600/month, which a site taking 1,000+ submissions a month burns through fast.
What it replaces: Chili Piper plus a separate enrichment step plus a scheduler.
Where to start: measure your current lead-to-first-touch time. Past an hour, fix routing before you fix sequencing.
Drift — sunset by Salesloft after the merger. Its conversational capability moved to 1mind. Do not shortlist it.
Groove — owned by Clari since August 2023 and overlapping with Salesloft inside the same company. Not a standalone purchase decision in 2026.
Mixmax, Yesware — email productivity tools. Real products, wrong category.
HubSpot Sales Hub sequences — the right answer if you are already on Pro or Enterprise. Do not buy a platform on top until native cadences have visibly run out of room.
Smartlead, Instantly — cold-email infrastructure for high-volume sending and mailbox rotation, not rep workflow. Different job, and buying one for the other disappoints in both directions.
The pick
The spread on this page is roughly $4.7K/year (five Apollo seats) to ~$51.5K/year (Regie’s median contract) — an eleven-fold range across products that all “do sequences.” Size before feature-matching.
Under 25 reps, outbound is a real motion → Apollo. Data and sequencing on one contract, and the MCP server is free.
25–100 reps → Clari + Salesloft. Lower seat minimum than Outreach, forecasting included, and the agent reach nobody else in the band has.
100+ reps, complex territories and permissions → Outreach. The admin depth earns its premium at that scale and nowhere below it.
Replacing the engagement layer rather than extending it, with ~$50K/year to commit → RegieOne.
Inbound is where pipeline actually originates → Default, before any of the four above.
If you cannot decide, buy Salesloft. It is the lowest-regret pick across the widest band of team sizes, and the merger risk is priced into a negotiation you can walk away from.
If none of them fit — reply rates are flat, meetings are not landing, and the sequencer is not obviously the constraint — the engine is not your problem. Data quality is. Spend on Clay first and re-run this decision in two quarters. The best sequence in the category still fails against a bad list.
