Sales & Marketing · HOLD.co portfolio
SalesDeveloper.ai — an AI sales development rep that runs the whole outbound loop.
SalesDeveloper is an agentic AI SDR platform. Six coordinated agents find prospects that match your ICP, research each account, write outreach from what the research found, run email and LinkedIn as a single sequence, read and answer the replies, and book the meeting on your rep’s calendar. It is sold as a module on the erp.io suite — a seat, not a second subscription.
A HOLD.co company
Built by an operator that has to fill its own pipeline.
SalesDeveloper.ai sits in the HOLD.co sales and marketing segment alongside Digital.Marketing, SEO.co, PPC.co, VID.co, Link.Build and PR.Digital — the brands that generate demand for the rest of the portfolio.
It exists because HOLD.co runs the same problem across a dozen operating companies. Every one of them needs first meetings, every one of them has tried hiring for it, and the economics are the same each time: a long ramp, high turnover, a loaded cost past six figures per seat, and a pipeline that moves only while someone is manually pushing it.
The brand was previously OmniSelling.ai. It was renamed to SalesDeveloper.ai in September 2026 because the name should say what the product replaces, and the old domain now redirects here.
The problem
Outbound is the function companies rebuild most often.
Sales development is rarely abandoned and rarely stable. Teams hire into it, watch the seats churn, hire again, and end up paying for the ramp far more often than they pay for the output.
The ramp is longer than the tenure
A new sales development rep takes months to reach full productivity, and the role has the highest turnover in B2B sales. A meaningful share of the seats a company pays to ramp never finish ramping, and every departure restarts the clock.
The loaded cost is not the salary
Base, commission, benefits, tooling, management time and recruiting fees put a fully-loaded seat well past six figures a year. Most teams run several, which is how a function that produces first meetings becomes one of the larger lines in the plan.
Pipeline stops when the team does
Buyers research at night, over weekends and across time zones. A human outbound motion covers business hours in one of them, and the gap is not a coverage problem so much as a response-time problem — the first credible reply usually wins the conversation.
Personalization collapses at volume
The research that makes a cold message worth reading is exactly the work that gets dropped when the quota is weekly. What survives is a template with a merge field, which is indistinguishable from every other template with a merge field.
How it works
Discover, engage, convert — as one continuous loop.
The pipeline is not a set of tools a rep moves work between. It is one agent system that carries a prospect from the list it built to the meeting it booked, and hands over to a person at the point where a person adds something.
01
Discover
The agent takes your ideal customer profile and works a contact database against it — firmographic fit, technographic signals, hiring and funding activity — and keeps the list refreshed rather than building it once. Which prospects convert feeds back into what it looks for next.
02
Engage
Every account is researched before the first touch, and the message is written from what that research turned up: a recent hire, a funding round, a job posting, a change in the stack. Email and LinkedIn run as one sequence, not two parallel silos.
03
Convert
Replies are read and classified — interested, objection, out of office, unsubscribe — and answered accordingly. When a prospect is ready, the agent proposes times against the rep's calendar, confirms, sends the invite and writes the pre-meeting briefing.
The platform
Six agents, each owning one job in the pipeline.
Splitting the work this way is what makes the system debuggable. When outbound underperforms, the question is which agent is wrong — the list, the research, the timing, or the reply handling — rather than whether “the AI” is working.
AI SDR agent
The orchestrator. Holds prospect state across the pipeline, prioritizes the queue, and decides what to advance, pause or re-engage.
Prospect discovery
Searches the contact database against your ICP, applies firmographic and technographic filters, and tightens its criteria as outcomes come back.
Personalization engine
Researches the account before the first touchpoint — funding data, news, LinkedIn, job boards, your CRM — so the message cites something verifiable.
Sequence execution
Runs multi-step, multi-channel timelines for every active prospect: send-time optimization, inbox rotation, deliverability, and branching on engagement.
Reply intelligence
Reads every inbound reply, classifies the intent behind it, and drafts the response — advancing the interested ones and handling the common objections.
Meeting booking
Takes over the calendar exchange end to end: proposes times, parses counter-offers, confirms, sends the invite, and briefs the rep before the call.
Channels
Email and LinkedIn, sequenced together.
Most outbound stacks run channels as separate campaigns that happen to point at the same person. SalesDeveloper runs them as one sequence, so a connection request knows what the email said and a follow-up knows whether the profile was viewed.
Volume without deliverability is just a suspended domain, so the sending side is part of the product rather than an integration: multiple sending domains with warmup, inbox rotation, bounce handling, and follow-ups that stop the moment a prospect replies.
There is a third channel in the product, and it is worth being precise about what it does. SalesDeveloper generates call scripts — persona-specific talk tracks with openers, discovery questions and objection paths, built from the same account research. A person makes that call. The agent does not dial.
What stays yours
Autonomous is not unsupervised.
The agent runs without a human coordinating each step. That is different from running without anyone able to see, stop, or correct it — and the difference is what makes the first one safe to switch on.
Where it plugs in
The CRM stays the system of record.
SalesDeveloper is a pipeline generator, not a replacement for the systems the revenue team already runs. It writes what it did back to them and leaves the reporting where the team already reads it.
What it costs
A seat on the suite, not a second subscription.
SalesDeveloper is a module on the erp.io suite, so it is priced the way every other module is: $20 per user per month on Starter, $99 a month for Growth, $399 a month for Scale, and a quote at enterprise. Every plan comes with a 30-day trial and no card.
Prospects, sequences and replies are unlimited on every tier. Pricing outbound by contact volume charges a customer for the agent’s appetite rather than for the value it returned, and it makes the one thing a buyer wants to do — send more, to better-matched people — the thing that costs them most.
The page carried volume-banded tiers until September 2026 and no longer does. Quoting a second monthly fee to a company already paying for suite seats was a price the platform had no way to charge and no good way to explain.
Who it serves
Companies that need first meetings faster than they can hire for them.
The pattern repeats across every one of them: a defensible ICP, a sales team that closes well and prospects unevenly, and a growth plan that assumes more pipeline than the current headcount produces.
Where it doesn’t fit
Three things it is honest about not being.
It is not the inbound side. SalesDeveloper opens conversations that did not exist; answering the phone when a prospect calls back is Phony.ai, the HOLD.co brand in the technology segment. The two are sister products on the same suite, and neither one is a substitute for the other.
It does not make compliance someone else’s problem. Outbound email and LinkedIn outreach are the sender’s legal obligation in every jurisdiction that regulates them, and no platform can assume that on a customer’s behalf. What the product does is make each message attributable, honor unsubscribes across the workspace, and stop a sequence the moment a prospect asks it to.
It does not close. The agent’s job ends at a booked, qualified meeting with a briefed rep on the other side of it. Discovery, the proposal and the negotiation stay with a person, and a company without anyone to take those meetings should fix that before adding pipeline.
Our thesis
Sales development is the one revenue function where the work is well specified, the ramp is long, and the tenure is short. That combination is what software takes first — not because the job was easy, but because nobody was ever able to staff it the way the plan assumed.
Point it at your ICP and watch a week of it.
Every sequence the agent writes is reviewable before it sends, so the first week is a read of its judgment rather than a leap of faith. Start a 30-day trial without a card, or read the platform in full first.
