How PartnerBridge added 15 qualified meetings a month without adding headcount.

Tannto runs PartnerBridge’s outbound function end to end: email and LinkedIn, separated sending infrastructure, AI personalisation, reply triage, and meeting booking. PartnerBridge gets a managed outbound channel without hiring SDRs or pulling the founder back into prospecting.

Qualified means the buyer sits inside the ICP agreed at onboarding, is in a relevant decision-making role, and is accepted by PartnerBridge as a real sales conversation. Outcomes vary by ICP, offer, market, and timing.

A strong SaaS product, but no outbound channel they trusted.

PartnerBridge is an Edinburgh-based partner intelligence SaaS startup for B2B SaaS. The product gives Heads of Partnerships and Channel Directors a clearer picture of which partner relationships are actually moving revenue. Strong category point of view. Three real product lines. A founding team carrying three SaaS exits between them, with senior partnership and solutions leadership at FullStory and SiteSpect on the founder’s CV. The thing missing was a steady, predictable flow of qualified meetings with the right buyers.

Done-for-you, end to end.

The work runs in three phases.

Phase 01
Setup and build
Email infrastructure provisioned in week one. Around 90 dedicated mailboxes across multiple sending domains, none carrying the PartnerBridge brand, so deliverability problems on a sending domain never touch the main one. 25 sends per mailbox per day, capped. Mailboxes warmed across Google Workspace and Microsoft 365 for three weeks before any cold send went out. In parallel: custom intent-signal scrapers built around partner-org buying patterns, AI-personalised copy drafted and voiced for PartnerBridge's brand, ICP locked in writing (Heads of Partnerships, Channel and Alliances Directors, and VP-level GTM at MarTech and AdTech SaaS in the UK and US).
Phase 02
Volume ramp
Sequences live across cold email and LinkedIn outreach in parallel. Volume scales by adding inboxes, never by burning the ones already running. Every positive reply triaged and answered within five minutes by AI agents conditioned on the original outbound and the live calendar; meeting confirmation and calendar handoff routed cleanly back to the PartnerBridge team. Weekly iteration on copy and ICP against the live data.
Phase 03
Steady state
The system reaches its current cadence by week 12. Around 15 qualified meetings appear on the calendar each month at steady state. The team's only outbound responsibility is showing up to the calls. The monthly performance report covers what is working, what is not, and the next cycle's optimisation actions.

Before and after.

Before Tannto

No outbound function in place
No appetite for SDR hires in the next 12 months
Pipeline coming from inbound and manual LinkedIn outreach
Founder time getting pulled into prospecting whenever pipeline thinned

After Tannto

End-to-end outbound across email and LinkedIn, run by Tannto
Around 15 qualified meetings booked per month, on average
Pipeline diversified beyond inbound and referrals
Founder time freed for product, partnerships, and closing

Outcomes.

Meetings.

PartnerBridge has typically booked around 15 qualified meetings a month from the Tannto-run outbound system, across email and LinkedIn.

No additional headcount.

No SDR hire. No SDR manager. No onboarding cost. No churn risk. The same pipeline gets generated by infrastructure that runs continuously and gets sharper every cycle.

Founder time freed.

Jon’s week goes to product strategy, partnership conversations, and closing. He doesn’t spend it babysitting a sequence editor or training a junior rep.

An additional pipeline source, not additional headcount.

The traditional path for a B2B SaaS company that needs more pipeline is: hire an SDR, hire a sales-engagement tool, write the playbook, train the SDR, wait six to nine months, see if it worked. For lean SaaS teams, the cost of getting that wrong is a meaningful fraction of the next funding round.

If your pipeline depends on outbound but your team doesn’t have the bandwidth to build and run it, this is the conversation to have.
