Lateral hiring is one of the most expensive and high-stakes growth strategies used by professional services firms, particularly among the AmLaw 200. Beyond its strategic importance, lateral hiring represents a significant capital investment that you expect to generate measurable return. When a lateral hire fails to meet expectations, it delays or jeopardizes your firm’s return on its investment.
Many firms invest heavily in recruiting laterals based on reputation, expertise, and a portable book of business, yet only 28% of lateral hires hit expected billings in their first year, even when you follow widely accepted law firm lateral hiring best practices.
Execution after the hire is where most firms struggle and where ROI is ultimately won or lost. Oftentimes, a lateral hiring strategy for professional services focuses only on recruiting aspects such as compensation, guarantees, origination credit, and the lateral partner questionnaire (LPQ). Far less attention is paid to what happens after your offer is signed. Without a clear plan to integrate laterals into client work, existing firm relationships, and business development efforts, you risk client porting issues, delayed productivity, and early attrition, undermining the very growth you hired for.
Why a lateral hiring strategy for professional services falls short without integration
Most firms devote 80% of their lateral hiring efforts to recruiting and negotiating salaries, leaving limited focus on integration and long-term success.
As a result, you end up facing challenges like:
- Limited visibility into relationships: You lack a clear view of who a lateral hire actually knows and where those relationships intersect with existing clients, prospects, and partners.
- Slow, siloed onboarding: Laterals are often expected to find their own way into the firm, rather than being intentionally pulled into the right conversations and opportunities by your teams.
- Missed business development opportunities: New partners bring valuable relationships, but without structured collaboration, those connections rarely translate into more growth for your firm.
Complex post-merger integration
Integration challenges go well beyond aligning compensation or practice groups. In many cases, mergers are announced long before systems and data are fully combined, leaving you with limited visibility into client relationships during a critical transition period.
That lack of clarity creates risk. Clients may be unsure who their primary contact is or whether their trusted advisors will remain involved, while competitors often use merger announcements as an opportunity to step in. Internally, your teams may continue operating in silos, unsure how their relationships overlap with existing clients or colleagues.
Without a clear lateral hiring strategy for professional services that prioritizes integration, you may struggle to turn new hires into sustained growth and this gap between hiring and integration remains one of the most persistent challenges in law firm lateral hiring best practices.
The research behind lateral hiring success
Research increasingly shows that an effective lateral hiring strategy for professional services depends less on recruiting inputs and more on post-hire execution. For example, Heidi Gardner, Harvard Law School Distinguished Fellow and CEO of Gardner & Co., has shown that lateral hire success depends on two critical factors.
- Lateral hires must be integrated into core client work early: partners who participate in billable matters or pitches within the first six months are far more likely to become productive, long-term contributors to your firm.
- Success requires active support from incumbent partners: when you create an environment where laterals are intentionally pulled into opportunities rather than forced to push their way in, collaboration and retention improve significantly.
Gardner’s work also highlights the financial impact of thoughtful integration strategies with boomerang hires delivering recruiting savings of around $50K per return hire. While boomerang hiring is only one piece of the puzzle, it underscores how much cost and risk can be reduced when firms focus on integration more than on replacement.
This emphasis on integration over recruitment inputs is increasingly reflected in firm behavior. For example, White & Case has made lateral partner integration a formal business development function, prioritizing team hires, dedicated integration staff, and accountability from incumbent partners, addressing a common gap in lateral hiring strategies: what happens after the offer is signed.
Thomson Reuters’s research reinforces this point, showing that lateral hire flight risk is strongly influenced by the quality of the integration experience. The more satisfied a lawyer is with onboarding and collaboration, the more likely they are to stay and succeed.
Timing is central to these findings. Early participation in matters and pitches improves collaboration and accelerates productivity since faster integration helps lateral hires contribute sooner and creates a clearer path to return. Integration speed therefore plays a meaningful role in how quickly firms realize value from lateral hiring.
Speeding up conflicts clearance with relationship data
Conflicts clearance is an unavoidable and often time-sensitive part of lateral hiring, and a recurring consideration in law firm lateral hiring best practices, particularly when you operate at scale. Delays or late discoveries can stall onboarding, disrupt client planning, or create unnecessary friction after you’ve already invested significant time and resources.
For firms making substantial commitments to lateral hires, conflicts-related delays also introduce financial risk by extending non-billable periods and increasing uncertainty around when expected contribution can begin. This challenge is especially pronounced for AmLaw 200 firms managing complex client portfolios and lateral volume.
Early visibility into relationship connections via relationship mapping helps you identify which clients, counterparties, or entities may warrant closer review. This allows you to begin asking more targeted questions earlier in the process, reducing the likelihood of late-stage issues that disrupt onboarding timelines and helping firms protect the value of your lateral hiring investment.
How Introhive for lateral hiring drives growth opportunities
Introhive strengthens lateral hiring strategies by making relationship data visible, actionable, and firm-wide.
Capitalizing on new relationships
When a lateral partner joins, they bring more than expertise. They bring relationships that represent real growth potential for your firm.
Introhive helps law firms:
- Automatically ingest relationship data from email and calendar activity.
- Identify overlap between a lateral hire’s network and firm clients or prospects.
- Surface warm paths for cross-practice and cross-office collaboration.
For example, after acquiring a Chicago-based advisory practice, firm leadership can quickly see how incoming partners’ relationships align with existing clients, industries, and regions without relying on self-reported spreadsheets.
The new hire’s perspective: navigating the firm and building trust
From a lateral hire’s point of view, the early challenge is understanding your firm.
- Who has worked on my assigned accounts before?
- Who has existing relationships at those companies?
- Who can I collaborate with inside the firm to build rapport and client trust?
Introhive provides immediate visibility into firm-wide relationship history, you help them prioritize the right conversations, become billable sooner, and avoid the friction that often undermines early success.
Activating opportunities across business development and marketing
Marketing, business development, and firm leadership all want to maximize the value of new relationships, but only if those relationships are visible.
Introhive allows teams to:
- Generate reports on new contacts brought in by lateral hires.
- Filter by location, industry, or job title to identify the best opportunities.
- Strategically align business development by connecting the right people.
For example, your firm just hired a lateral partner with strong connections in private equity and you want to quickly assess how these new relationships align with existing firm clients. Instead of spending weeks manually compiling contact lists, you can use Introhive to highlight:
- Which PE firms in the lateral hire’s network are already firm clients.
- Where there are new business opportunities based on shared relationships.
- Which existing partners should collaborate with the new hire to pursue deals.
The 30-60-90 day plan
For a lateral hiring strategy for professional services to succeed, you need a clear, time-bound integration framework. A defined 30-60-90 day plan helps you align leadership, BD, and practice teams around what “successful integration” actually looks like.
- Day 1–30: Build visibility into relationships and risks.
- Day 31–60: Activate warm paths and collaboration.
- Day 61–90: Focus on revenue signals and early traction.
Day 1-30 (the mapping phase)
Introhive automatically ingests relationship data from the new hire’s email and calendar activity to build a clear picture of who they are connected to. You can identify where those relationships overlap with existing clients, prospects, industries, and geographies, creating an early view of potential collaboration opportunities.
This initial mapping also supports onboarding and early-stage conflicts review by helping teams identify which entities may warrant closer attention so that risk and leadership teams can engage sooner and with better context.
Day 31-60 (the cross-selling phase)
By identifying warm paths between the lateral hire and existing partners, you make it easier to connect the right people around shared clients and growth opportunities. This helps business development teams can help coordinate introductions, prioritize accounts, and align outreach across practices and offices.
Relationship intelligence can also help surface where relationships originate and how different professionals have contributed to strengthening those relationships, providing useful context for collaboration and origination credit discussions.
Day 61-90 (the revenue phase)
Using relationship strength and recency as signals, teams can prioritize pitches, support client porting efforts, and track early indicators of success such as participation in active matters, joint pitches, and cross-practice collaboration. Even a strong portable book of business can stall without early collaboration and internal alignment.
This phase helps you move beyond activity to outcomes, providing early insight into whether your new lateral hire is gaining traction and where additional support may be needed.
Measuring the return on lateral hiring
The success of a lateral hiring strategy for professional services requires you to look beyond eventual revenue alone. Because revenue is a lagging indicator, you need to focus on what happens in the first 18 months, when you can determine whether a lateral hire will deliver a return or become a retention risk.
Within that window, early indicators matter. Time to first billable matter, participation in active matters or pitches, and early cross-practice collaboration provide critical insight into whether a lateral hire is becoming embedded in client work and firm relationships. These signals help you understand whether integration is taking hold early enough to support long-term success.
Over time, you can assess broader measures of impact, including cross-practice revenue influence and collaboration depth within key accounts. Studies have shown that multi-threaded accounts (where multiple professionals maintain active relationships) deliver a 34% increase in deal win rates, reinforcing the financial value of early and sustained collaboration.
Retention is another critical component of return. Failed integrations increase the likelihood of attrition, forcing firms to absorb the substantial cost of replacement, often estimated between $200,000 and $350,000 per departed associate or partner. By identifying integration challenges early, you’re better positioned to protect your original hiring investment and accelerate time to value and realize contribution in months rather than years.

Frequently asked questions
What is the biggest challenge in lateral hiring?
One of the biggest gaps in a lateral hiring strategy for professional services is client porting, the ability to successfully transition client relationships and revenue to the new firm.
Even when laterals arrive with a strong portable book of business, client porting often falters when firms lack clear visibility into existing relationships and don’t actively connect the lateral with the right partners and teams early on. Without that coordination, client conversations are delayed, introductions happen inconsistently, and expected revenue takes longer to materialize.
How do you measure lateral hire success?
Lateral hire success is typically measured using a combination of early and medium-term indicators, including time to first billable hour, participation in active matters or pitches, and cross-practice collaboration.
Firms can also look for signs that their new hire is becoming embedded in client work and firm relationships, such as joint pursuits with existing partners and growing involvement across practices. These indicators provide earlier insight than revenue alone and help leadership identify where additional support may be needed.
