For B2B SaaS founders, CEOs and sales leaders

A sales system your team can run and trust, in your HubSpot.

We build the system in your HubSpot: the process your sellers follow, data your team trusts, and an AI SDR that turns buying signals into conversations. Your team closes, and the system stays yours.

Show Sergey where your sales get stuck. Leave with a plan and one fixed price.

Which one is you?

What it costs

The Build is the one-time phase in which we build the system result by result: each result has a fixed price, and you pay for it after it is verified, with no upfront fee. After the Build, you choose whether to continue with Improve, a retainer: a fixed monthly fee agreed with you, for a named engineer instead of hiring a GTM engineer.

Starter project

Can start at around $2,000 to $3,000

One useful result, such as company-level visitor identification, a fit score or a sync between your CRM and HubSpot.

Is now the right time?

Right time if

  • You have closed the first deals yourself and want your first seller to sell the next ones
  • You just took over sales and need a system your team can trust
  • Your sales team works, but the growth target is out of reach with the current system
  • You pay an outside SDR agency and want outreach to run from your own HubSpot

Too early if

  • You are still finding out who buys
  • Nobody sells and there is no self-serve sign-up to convert
  • You want us to sell for you

From a buying signal to a call with your team, in your HubSpot

The outreach part of the system is an AI SDR: software that does the research and outreach a sales development rep would do, built inside your HubSpot and working in your name.

All inside your HubSpot

  1. Signals

    It watches for companies showing they may be ready to buy from you: a new hire, a funding round, repeat visits to your key pages.

  2. Qualify and score

    It checks each company against your ideal customer and scores the timing.

  3. Outreach

    The AI SDR runs the outreach you agreed, from your accounts, and follows up. Replies outside the rules go to a person.

  4. Call, demo or sign-up

    Qualified prospects land on your team's calendar. Where buyers sign up on their own, it takes them to a demo, trial or subscription.

It runs in your HubSpot and your accounts, on rules you agree. Your team takes the calls and closes the deals.

Outside SDRs or a system you own

Outside SDRs book meetings from their own tools. The AI SDR we build is made to replace them, inside your HubSpot.

SDR agency Your system, built by Selleris
Where outreach runs The agency's tools and accounts Your HubSpot and your accounts

From our research

What founders and sales leaders say

We read 375 accounts from founders and CEOs of B2B software companies and 1,091 records on how companies build or buy their sales system, in public interviews and posts. Every quote links to its source.

  • The wall is the handoff

    For founders who sell, growth stalls at the handoff, when someone else has to sell the way they do.

    Basis: 375 founder and CEO accounts at 351 B2B software companies. Among the founder accounts, deciding whom to hire is the most frequent trigger (107 accounts), ahead of not enough pipeline (78) and a flat revenue line (29).

    • “it's so hard to transfer from founder led sales to process led sales.”

      Christopher Day, co-founder and former CEO, DemandJump

  • Most founders who take a side say the sale has to repeat before the scaling hire

    116 of the 138 founder and CEO accounts that take a side say the sale has to repeat before the hire meant to scale it.

    Basis: 116 of the 138 founder accounts that take a side on the order of things support building a repeatable sale before the hire meant to scale it. The cost founders name is time and runway more than salary.

    • “They closed few deals, each one of them, and then there was a lull for next four to six weeks.”

  • A new sales leader inherits a system nobody trusts

    A new sales leader often inherits a system nobody trusts, and has to reset it.

    Basis: A second round of 1,091 records on how founders build or buy their sales system, with podcast interviews, Hacker News threads and CRM reviews: rework of the sales system is common, comes after a change in who sells, and usually concerns the process or the sales model.

    • “So this was, like, the first hard reset.”

FAQs

Questions of founders and sales leaders

I am about to hire my first seller. When should we start?

Before the seller starts, or in their first three months: the system is built from your last deals, so it is ready when the seller needs it.

I just took over sales. Can you work with the system I inherited?

Yes. The diagnostic starts from what you have: we review your pipeline, data and recent deals, then agree which results to rebuild first, such as data, lifecycle stages and routing, each with a fixed price.

Our team already sells. Can you work with what we have?

Yes. The diagnostic starts from your growth target and the system you have today: we review your pipeline, data and recent deals, then agree which results to build first, each with a fixed price.

We use another CRM. Do we have to switch?

No. Your CRM stays: we connect it and sync its data with HubSpot, prove the approach on a slice, then build the system on HubSpot.

Do you find leads or sell for us?

No. We build the system in your HubSpot; the AI SDR works in your name on rules you agree, and your team closes the deals.

How much does it cost?

A starter project can start at around $2,000 to $3,000 for one useful result. Each Build result has a fixed price and is paid after it is verified, with no upfront fee; after the Build, Improve is your choice: a fixed monthly fee agreed with you. Full pricing is on the pricing page.

What is an AI SDR, and is Selleris one?

An AI SDR is software that does the work of a sales development representative (SDR): it researches accounts, writes and sends outreach, follows up and books conversations. Selleris is a GTM engineering agency, not an AI SDR subscription: we build an AI SDR inside your own HubSpot, connected to the rest of your system, and you own it. It starts by preparing work for review and acts on its own only in the scenarios you agree; replies outside the rules and exceptions go to your team. Where you sell on calls, your team closes the deal; where buyers sign up on their own, the system takes them to a demo, trial or subscription.
