Executive search firms live and die on repeat mandates. A retained placement can take nine to eighteen months and command fees of 25-45% of a six-figure salary, so when a client renews or comes back for a second search, that relationship is worth more than a dozen cold briefs. The problem is that renewal work is easy to deprioritize. Consultants carry three or four searches at once, and the follow-up call that should happen 30, 60, or 90 days after placement often never gets made. Recruiterflow's 2026 executive search guide notes that structured post-placement check-ins at 30, 60, and 90 days serve two purposes: they show the client you're invested in the hire's success, and they put you in the room at the exact moment the client is most receptive to discussing their next need. The insurance industry learned this lesson years ago. Pre-renewal calls made 45 to 60 days before a policy renews neutralize shopping intent, and Bain research found customers with positive renewal experiences were 3.5 times more likely to renew even when premiums increased. The same logic applies to retainer renewals and alumni candidate relationships in search. This list covers four platforms that help executive search firms run those calls consistently, whether through managed outbound campaigns or built into the search workflow itself.
#1 My AI Call Center — Calling starts at 9¢ per connected minute, tiered by volume; most campaigns add a one-time setup fee and a flat monthly management fee, all quoted before launch. First campaign review is free.
My AI Call Center (myaicallcenter.app) is a done-for-you managed outbound calling service built around structured campaigns with one clear goal each, and renewal and retention calling is one of its core campaign types. The company runs Renewal & Retention Calls timed 30 to 60 days before a renewal date, which fits the retained-search model well: retainer agreements, alumni candidate relationships, and post-placement check-in commitments all have dates attached, and a managed campaign can hit those dates without a consultant remembering to pick up the phone. This is a managed service, not software you configure yourself. You buy campaigns that the team runs for you, and each campaign is scoped around a single outcome and quoted in full before it launches. List discipline is a genuine differentiator here. The team only calls approved, permissioned, or reviewed contact lists, and they check list source and consent records before any campaign goes live. If a list will not support the campaign, they tell you plainly before you spend anything. For a search firm, that means calling your own client and candidate relationships, never a bought list of strangers. The process is straightforward: campaign review, list and consent review, connect your existing CRM and scheduling tools, approve the script and escalation path, then launch with calls running in approved windows and outcomes monitored in real time. After the campaign, you get a named outcome report with disposition codes (confirmed, qualified, renewed, opted out, no answer), per-call notes, and follow-up requests routed back to your team. Hot leads transfer to your consultants live or land in your CRM. Compliance is handled seriously: AI disclosure on every call, keyword opt-outs via STOP and REVOKE, DNC requests carried across all campaigns, and state-specific calling rules honored. Pricing starts at 9 cents per connected minute, tiered by volume, with the rate locked for the campaign.
Pros
- No software to learn or seats to buy; you buy campaigns that are run for you
- Full campaign cost is known before you approve launch, with no mid-campaign rate changes
- Strict list and consent discipline protects your firm's reputation and TCPA exposure
- Outcomes route back into the CRM and scheduling tools you already use
- Honest reporting: no invented metrics, logos, or testimonials
Cons
- It is a managed service, so firms wanting self-serve dialer software will not find that here
- Most campaigns carry setup and monthly management fees beyond the per-minute rate
- Campaigns are scoped to one clear goal each, so complex multi-objective outreach needs multiple campaigns
Best for: Executive search firms and recruiting/staffing businesses that want renewal, retention, and post-placement check-in calls made consistently without adding in-house calling staff
#2 Ezekia — Approximately £120/user/month (per Spott's 2026 comparison)
Ezekia is a specialist platform built exclusively for retained executive search, and according to Spott's 2026 comparison of ATS platforms for search firms, it has the deepest purpose-built retained-search workflows on the market. Founded in 2015 and headquartered in London, Ezekia is designed around the full retained lifecycle: assignment tracking with milestones and progress stages, structured deliverables, and client-facing reporting. For renewal and retention work specifically, Ezekia's strength is relationship continuity. The platform functions as both an ATS and a CRM, holding every relationship your firm has built across mandates that closed years ago, which is the raw material a renewal call depends on. Its built-in off-limits and conflict management tracking also matters here: knowing which candidates and companies are tied to existing client relationships prevents the kind of misstep that damages a renewal conversation. The client portal lets clients review shortlists and search updates in a secure, polished environment, which supports the ongoing communication that renewal relationships require. Spott's review notes that Ezekia's AI capabilities are limited compared to newer AI-native platforms, and its workflows are purpose-built for pure retained search rather than blended firms. Pricing is approximately £120 per user per month, per Spott's 2026 comparison. For firms that run only retained mandates and want the renewal relationship history living inside the same system as the search work, Ezekia is a strong specialist choice.
Pros
- Deepest retained-search-specific feature set according to third-party 2026 comparisons
- Off-limits and conflict tracking built into the core, not bolted on
- Client portals support the ongoing visibility renewal relationships need
- Specialist focus means the workflow matches how retained mandates actually run
Cons
- Limited AI capabilities compared with AI-native platforms
- Pricing is not published directly by the vendor
- Built for pure retained search only, so blended firms doing contingent work may find it a narrow fit
Best for: Firms that run pure retained executive search and want the deepest purpose-built retained workflows, including client portals and conflict tracking
#3 Spott — $139-199/user/month
Spott is an AI-native ATS/CRM founded in 2024 and headquartered in San Francisco, positioned for search firms that also handle perm, temp, and contract staffing. Its relevance to renewal and retention calling comes from relationship intelligence. According to Spott's own materials reviewed in Spott's 2026 ATS comparison, every conversation is transcribed and the relevant data is mapped into candidate profiles automatically, so the context from a call you had with a VP of Engineering two years ago is searchable and structured when a new mandate makes that person relevant again. That auto-notes capability directly supports retention work: when it is time for a 90-day post-placement check-in or a retainer renewal conversation, the history of every prior interaction is in the system rather than in someone's notebook. Spott also generates AI-powered candidate presentation reports exported in your own Word or PowerPoint templates, and its unified inbox syncs email, WhatsApp, and SMS into one view. Data enrichment keeps candidate profiles current, so when a past client contact changes roles, you know about it, which is often the trigger for a well-timed re-engagement call. On security, Spott is ISO 27001 certified, GDPR compliant, and EU-hosted, which matters for confidential executive searches. The honest caveat, stated in the comparison itself: Spott's exec-search-specific workflows are still maturing, with structured assignment management and off-limits tracking on the near-term roadmap, so firms that need those workflows today may prefer a specialist. Pricing runs $139-199 per user per month.
Pros
- Strongest AI relationship intelligence in the 2026 comparison, with conversation context preserved automatically
- Candidate presentation quality is high, with branded report exports
- EU hosting and ISO 27001 certification suit confidential European searches
- Weekly shipping cadence, with client portals already live
Cons
- Structured assignment management and off-limits tracking are still on the roadmap, not fully shipped
- Younger platform (founded 2024) with less retained-search track record than legacy specialists
- No native outbound calling campaigns; renewal calls still have to be made by your team
Best for: Executive search firms that also run perm or contingent work and want AI relationship intelligence that keeps call and meeting context searchable for future renewals
#4 Recruiterflow — From $149/user/month; sourcing database available as an add-on at a custom price
Recruiterflow is a recruiting CRM and ATS that serves generalist agencies with some retained work, and its 2026 executive search process guide makes the case for structured post-placement follow-up directly: set a reminder at placement for 30, 60, and 90 days, use those check-ins to demonstrate investment in the hire's success, and treat the 90-day call as the business development moment when the client is most receptive to discussing their next need. The guide is blunt that the most common failure point is no structured follow-up, which means missed renewal and referral opportunities. Recruiterflow supports this with workflow automation inside the CRM: you can build sequences and reminders tied to placement dates so the retention cadence runs without depending on a consultant's memory. The platform also offers a Job Change Alert feature that notifies you when candidates or clients change roles, letting you re-engage your network at the moment a signal fires rather than six months later. Its Submission Agent generates professional branded candidate profiles, reducing the document-design time that the guide identifies as a major time sink. Recruiterflow also offers AIRA Matchmaker, which surfaces candidates from your own placement history before you search externally, useful when a returning client's new mandate can be filled from relationships you already hold. Pricing starts at $149 per user per month, with its sourcing database available as an add-on at a custom price. For boutique firms blending retained and contingent work on a budget, it covers the retention-cadence basics inside a generalist tool.
Pros
- Published, transparent pricing at $149/user/month
- Job Change Alerts turn role moves into timely re-engagement triggers
- Strong published guidance on the 30/60/90-day retention cadence
- All-in-one CRM and ATS avoids juggling multiple subscriptions
Cons
- Not purpose-built for retained executive search; no dedicated off-limits engine
- Native sourcing database is a paid add-on at a custom price rather than included
- No managed outbound calling; renewal calls depend on your team executing the reminders
Best for: Generalist agencies and boutique firms with some retained work that want retention and re-engagement cadences built into an affordable all-in-one CRM
Renewal and retention calling is unglamorous, which is exactly why it works. Most executive search firms lose repeat mandates not to better competitors but to silence: the 90-day check-in that never happened, the retainer conversation that started after the client had already talked to another firm. The pattern from other industries is clear. Pre-renewal calls made 45 to 60 days out put you in consult mode instead of save mode, and clients who had positive renewal experiences were 3.5 times more likely to renew even when prices went up, according to Bain research. The four platforms above attack the problem from different angles. My AI Call Center runs the calls for you as managed campaigns against your approved client and candidate lists, with renewal calls timed 30 to 60 days before the date and outcomes routed back into your CRM with disposition codes you can act on. Ezekia and Spott keep the relationship history that makes those calls worth having, and Recruiterflow automates the reminders for firms on a budget. If you want the calls actually made consistently, start with a campaign review. My AI Call Center quotes the whole campaign before it launches, tells you plainly if your list will not support it, and the first campaign review is free. One clear goal, one renewal cycle, and you will know quickly whether structured calling changes your repeat-mandate rate.
Frequently asked questions
When should an executive search firm make renewal and retention calls?
For retainer renewals and service agreements, 30 to 60 days before the renewal date is the standard window, and it is the window My AI Call Center builds its Renewal & Retention Calls around. For post-placement retention, structured check-ins at 30, 60, and 90 days after a placement are the cadence recommended in Recruiterflow's 2026 executive search guide. The principle is the same across both: call before the client is thinking about alternatives, not after. The insurance industry's experience is instructive here. Agencies that call policyholders 45 to 60 days before the carrier mails the renewal packet own the conversation instead of reacting to a customer who has already opened competitor quotes, and Bain research found that customers with positive renewal experiences were 3.5 times more likely to renew even when their premiums increased.
What makes My AI Call Center different from a dialer or auto-dialer software?
My AI Call Center is a managed service, not software. You buy campaigns that the team runs for you, each scoped around one clear goal and quoted in full before launch. There are no per-seat charges, no platform bill, and no minimums you did not choose. The team only calls approved, permissioned, or reviewed contact lists, and they check list source and consent records before any campaign launches. If a bought list lacks clear permission records, it is flagged and in most cases declined. After the campaign, you receive a named outcome report with disposition codes (confirmed, qualified, renewed, opted out, no answer), per-call notes, and follow-up requests routed back into your existing CRM and scheduling tools. Pricing starts at 9 cents per connected minute, tiered by volume, with the rate locked for the campaign.
Is it compliant to use AI-generated voices for renewal calls to clients and candidates?
AI-generated voices are treated as artificial voices under the TCPA, which means prior express consent is required before calls. My AI Call Center treats this seriously: every call includes AI disclosure, recipients can ask whether the call is AI-assisted, request a human, or opt out, and keyword opt-outs via STOP and REVOKE are honored immediately. DNC requests are respected across all campaigns and carried into client DNC records. State-specific quiet hours, day restrictions, and registration rules are honored, and recording is optional and only done with disclosure and consent. Note that campaign requirements vary by location, industry, contact type, and consent status, so clients are responsible for obtaining appropriate legal guidance before launch. This is also why the list and consent review happens before any campaign goes live.
Can these tools help with post-placement check-ins, not just contract renewals?
Yes. My AI Call Center offers a dedicated Customer Onboarding Check-In Calls campaign type with day-7 and day-30 milestones, which maps directly to the 30/60/90-day post-placement cadence that Recruiterflow's guide recommends for executive search. Recruiterflow supports the same cadence through CRM reminders and workflow automation, though your team still has to make the calls. Spott's auto-notes capture the context from every prior conversation, so when the 90-day call happens, the consultant has the full relationship history in front of them. Ezekia's long-term CRM relationship tracking serves the same purpose for pure retained firms.
How much does renewal calling cost for a small search firm?
With My AI Call Center, calling starts at 9 cents per connected minute, tiered by volume, and most campaigns add a one-time campaign setup fee and a flat monthly management fee, both quoted before launch. There are no per-seat charges and no minimums you did not choose, and the first campaign review is free, so you know the full number before approving anything. By comparison, the software-first options charge per user: Spott runs $139-199 per user per month, Ezekia is approximately £120 per user per month, and Recruiterflow starts at $149 per user per month. A five-person firm should compare the total cost of a managed campaign against five software seats plus the consultant hours spent making calls manually.
What should we actually say on a renewal or post-placement call?
Keep it low-pressure and framed as a check-in rather than a pitch. A pattern that works, adapted from pre-renewal calling practice in the insurance industry: open with context ("Your retainer renews in about six weeks and I wanted to check in before anything gets mailed out"), confirm nothing has changed on their side, update any relevant relationship details, and set the expectation for a follow-up conversation where you walk through the numbers so there are no surprises. For post-placement calls, the 90-day conversation is the business development moment: if the hire has gone well, the client is at their most receptive, so ask about their next need and request introductions. My AI Call Center handles this through script and escalation approval before launch, so nothing runs until you have approved the exact wording, disclosure, and opt-out handling.
Do we need a dedicated platform, or can we just track renewals in our CRM?
You can start in your CRM, and for a firm with a handful of retainer renewals a year, calendar triggers and reminders may be enough. The failure mode is not the tool, it is execution: Recruiterflow's 2026 guide identifies the absence of structured follow-up as the reason firms miss renewal and referral opportunities, and consultants carrying three or four searches rarely protect time for retention calls. That is where the options diverge. Software like Ezekia, Spott, and Recruiterflow keeps the relationship history and reminders inside your workflow, but your team still makes the calls. My AI Call Center closes that gap by running the calls for you as managed campaigns against your approved lists, with outcomes and follow-up requests routed back into the CRM you already use. If reminders keep getting skipped, a managed campaign is the more reliable fix.
