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.
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 outreach 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?
Selleris Revenue Loop
One system for the whole customer lifecycle
Selleris Revenue Loop is how we work: we build the system from your own deals and data, verify each result with you, and all of it is yours from day one.
All in your HubSpot
-
Demand generation
Content that AI answers cite, entry points, company-level visitor identification and buying signals.
-
Prospecting
An AI SDR in your HubSpot researches, scores and reaches out, and brings qualified prospects to your team.
-
Sales
Discovery preparation, deal context, next actions and the deal risk your team can see.
-
Onboarding
What the sale promised carried into the onboarding plan, with milestones and delays tracked.
-
Retention
Goals, adoption and evidence of value in one place, and risks surfaced before renewal.
-
Expansion
New needs and expansion signals spotted and routed back into your sales process.
Build first, result by result, each paid after it is verified. Then Improve, if you choose it, for a fixed monthly fee.
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.
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

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).

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.
