For post-acquisition integration leaders

Two companies. Two cultures. One execution reality.

Integration leader reviewing unified execution dashboard across two merging organisations

The integration tax

Two companies decided to merge. Now who decides how?

Post-acquisition, decisions scatter across two organisations with different tools, cultures, and meeting rhythms. The integration plan lives in a spreadsheet that’s stale before the steering committee meets.

83%

of mergers fail to deliver expected synergies.

Not because the strategy was wrong, but because integration execution broke down. Decisions made in one organisation never reached the other.

Bain M&A Report

15+ workstreams

A typical integration runs 15 or more parallel workstreams, finance, IT, people, commercial, legal, operations. Each making dozens of decisions per week that affect the others.

Two tool stacks

Company A uses Slack and Notion. Company B uses Teams and Confluence. Integration decisions fall into the gap between them.

Cultural blind spots

One company decides in meetings. The other decides in documents. Neither side realises they’re making conflicting commitments until the deadline passes.

How In Parallel helps

From two organisations to one integration reality.

01

Cross-organisational decision capture

In Parallel joins meetings across both companies, leadership syncs, integration stand-ups, workstream reviews. Every decision, owner, and deadline is captured regardless of which organisation it came from.

02

Unified integration plan from meeting signals

Your integration plan updates itself from real conversations. When a finance workstream decision affects IT migration timelines, it surfaces immediately, not two weeks later in a steering committee.

03

Cultural drift detection

Two companies make decisions differently. In Parallel detects when teams are diverging from agreed integration milestones, before misalignment becomes cultural friction.

04

Synergy tracking against targets

Stop manually assembling synergy progress from scattered spreadsheets. In Parallel connects integration decisions to synergy targets so you always know what's on track and what's slipping.

Trusted by integration teams

An integration team hit Day 100 milestones three weeks early.

“For the first time, the steering committee could see what was actually decided across all workstreams, not what someone remembered to write down.”

Side by side

What changes when integration decisions stop disappearing.

Without In Parallel

  • Integration decisions scattered across two sets of tools and cultures
  • Steering committee reports assembled manually from 15 workstreams
  • Cultural misalignment discovered after it derails a workstream
  • Synergy targets tracked in spreadsheets nobody trusts
  • Day 100 looks exactly like Day 1, just with more meetings

With In Parallel

  • Every integration decision captured with owner, deadline, and context
  • Steering committee always sees real-time workstream status
  • Cultural friction detected early through decision pattern analysis
  • Synergy progress tracked automatically against board commitments
  • Integration velocity measurable and accelerating week over week

Built for integration

Both stacks. Both cultures. Zero behaviour change.

In Parallel layers onto whatever each organisation already uses. Nobody downloads an app. Nobody changes their workflow. Critical when you’re already asking people to change everything else.

Works with any stack

Both companies use different tools? Fine. Zoom, Teams, Google Meet, Slack, Notion, Jira, Asana, In Parallel layers onto whatever each organisation already uses.

SOC 2 + GDPR

Enterprise security that satisfies both organisations' compliance teams. EU data residency available. Audit reports on request.

Zero behaviour change

In Parallel joins existing meetings. Nobody downloads an app. Nobody changes their workflow. Critical when you're already asking people to change everything else.

Cross-organisational by design

Not a tool for one side of the deal. A coordination layer that works across both companies from Day 1, regardless of org structure.
