Going public requires assembling a team of eight to ten specialist advisors — each covering a distinct workstream. Most first-time public companies underestimate how early each role needs to be engaged, and how much the quality of each advisor affects both the timeline and the outcome.
The Eight Core IPO Advisors
While every IPO is different, the following roles appear on virtually every transaction. Some are mandatory by regulation; others are critical by practice.
Company IPO Counsel
Securities lawyers who draft the S-1, manage SEC correspondence, advise on disclosure, and coordinate the legal workstream. The single most important advisor selection you will make.
Investment Banks (Underwriters)
Lead bookrunner and co-managers who price the deal, run the bookbuild, manage the roadshow, and distribute shares to institutional investors.
PCAOB-Registered Auditor
Big Four or national firm that audits the financial statements included in the S-1. Must be PCAOB-registered. Requires engagement 18+ months before filing.
Accounting Advisory Firm
Separate from the auditor — advises on technical accounting (ASC 606, lease accounting, stock compensation), close process improvement, non-GAAP policy, and SOX readiness. Critical for companies with complex accounting.
D&O Insurance Broker
Specialist broker who markets D&O coverage to insurance carriers on your behalf. A generalist broker will not achieve competitive pricing in the D&O market.
Investor Relations Firm
Advises on messaging, investor targeting, and post-IPO IR program. Most companies hire 6–9 months before filing; the best IR firms get booked up earlier.
Transfer Agent
Maintains the shareholder register, manages DTC connectivity, handles equity plan administration, proxy services, and annual meeting logistics.
Financial Printer / EDGAR Agent
Files your S-1 and all amendments on EDGAR, provides the virtual data room for due diligence, and manages the production of the final prospectus.
When to Engage Each Advisor
18+ Months Before S-1: Auditor & Accounting Advisory
The PCAOB auditor needs 2–3 full fiscal year audits before the S-1 can be filed. Engage your auditor and accounting advisory firm simultaneously — both need to assess the current state of your financial reporting before the audit begins.
12 Months Before S-1: IPO Counsel
Securities lawyers need a full year to complete corporate clean-up — cap table audit, governance restructuring, material contract review, and Delaware reincorporation. Late engagement is one of the most common IPO timeline killers.
9 Months Before S-1: D&O Insurance Broker & IR Firm
D&O insurance takes 3–6 months to properly market to carriers. IR firms need time to build the investor targeting list and develop messaging before the S-1 is filed. Both are consistently engaged too late.
6 Months Before S-1: Underwriters (Bake-Off)
The underwriter bake-off typically runs 4–6 weeks and should be completed 6 months before the anticipated filing date. Banks need time to prepare their valuation views, comp sets, and investor targeting lists.
3 Months Before S-1: Transfer Agent & Financial Printer
Transfer agents and financial printers/EDGAR agents need to be in place before S-1 drafting begins in earnest. Both are relatively commoditized but require time to onboard your equity plan and configure EDGAR access.
Who Hires Whom
Understanding who controls each advisor relationship matters for fee negotiation and for managing conflicts of interest.
| Advisor | Hired By | Paid By | Typical Fee Structure |
|---|---|---|---|
| Company IPO Counsel | Company (CEO/GC) | Company | Hourly ($1.5–4M total) |
| Underwriters | Company (CEO/CFO) | Company (from proceeds) | 5–7% underwriting spread |
| PCAOB Auditor | Audit Committee | Company | Fixed fee ($2–6M/year) |
| Accounting Advisory | CFO | Company | T&M or fixed project fees |
| D&O Broker | CFO / GC | Commission from carrier | Embedded in premium |
| IR Firm | CFO / CEO | Company | Monthly retainer ($10–25K) |
| Transfer Agent | CFO | Company | Annual fee + per-transaction |
| Financial Printer | CFO / GC | Company | Per-filing + hourly edits |
| Compensation Consultant | Compensation Committee | Company | Hourly or fixed project |
The Advisor Most Commonly Engaged Too Late
In our experience, the accounting advisory firm is the most consistently under-resourced hire in an IPO preparation. Companies assume the auditor covers everything accounting-related — but the auditor's job is to audit completed financials, not to advise on how to prepare them. Technical accounting issues discovered late (ASC 606 misapplication, unrecorded lease obligations, stock compensation errors) are among the most common causes of S-1 delays and SEC comment letter rounds.

When to Engage Each Advisor
The sequencing of advisor engagements determines whether the IPO timeline holds. The most common mistake is starting the auditor too late — PCAOB rules require at least two years of audited financial statements in the S-1, which means the auditor needs to be engaged at least 18 months before the target filing date to audit the full required period.
| Advisor | Engage | Reason for Timing |
|---|---|---|
| PCAOB Auditor | 18–24 months before S-1 filing | Needs to audit 2 full fiscal years before filing; onboarding and independence procedures take 2–3 months |
| Accounting Advisory Firm | 18 months before S-1 filing | ASC 606 implementation, SOX readiness, and close process improvement all require 12–18 months of runway |
| D&O Insurance Broker | 12 months before S-1 filing | Pre-IPO D&O modeling requires current governance and financial data; early engagement improves access to competitive carriers |
| Investor Relations Firm | 9–12 months before S-1 filing | Pre-IPO non-deal roadshow and investor targeting take 6–9 months; best firms book up early |
| IPO Counsel | 9–12 months before S-1 filing | Governance restructuring, charter amendments, and pre-IPO legal cleanup require lead time before drafting begins |
| Underwriters (Investment Banks) | 6–9 months before S-1 filing | Run bake-off 6 months out; formal engagement letter signed 3–4 months before filing |
| Transfer Agent | 6 months before S-1 filing | Needs time to onboard equity plan data, set up DTC connectivity, and prepare for the share record conversion at IPO |
| Financial Printer | 6 months before S-1 filing | EDGAR setup, test filing procedures, and S-1 template formatting all need lead time before the first draft |
Advisor Fee Ranges
Understanding typical fee ranges helps CFOs build the pre-IPO budget and evaluate whether the quotes they receive are reasonable. All ranges assume a $200M–$500M IPO; fees scale with deal size and complexity.
| Advisor | Fee Structure | Typical Range |
|---|---|---|
| Underwriters | Spread (% of gross proceeds) | 5–7% of IPO proceeds; co-managers share ~20% of the spread |
| IPO Counsel (Company) | Fixed fee or hourly blended | $2M–$5M for a mid-market IPO |
| PCAOB Auditor | Annual audit + S-1 comfort letters | $1.5M–$5M/year (Big Four); $700K–$2M (national firm) |
| Accounting Advisory | Project-based or hourly | $500K–$2M for full pre-IPO engagement |
| D&O Insurance | Annual premium (not a broker fee) | $3M–$15M/year premium; broker commission embedded |
| Investor Relations Firm | Monthly retainer | $10K–$30K/month; most engage 9 months pre-IPO |
| Transfer Agent | Annual fee + per-transaction | $50K–$200K/year |
| Financial Printer | Per-filing + annual platform fee | $150K–$600K for S-1 project; $100K–$400K/year ongoing |
Running the Underwriter Bake-Off
The underwriter selection process — commonly called a "bake-off" or "beauty contest" — is typically run 6–9 months before the target S-1 filing date. Each investment bank presents to management and the board, covering their view of the company's equity story, comparable public company analysis, proposed valuation range, marketing strategy, and their distribution capabilities for the roadshow bookbuild.
What to evaluate in the bake-off:
- Analyst quality and coverage commitment: Who is the research analyst who will cover the stock post-IPO? What is their track record on comparable companies? How many companies do they cover? The analyst relationship persists for years — it is the most durable aspect of the underwriter relationship.
- Equity story and positioning: How does each bank frame the investment thesis? Which bank's version resonates most with management's own view of why the company is a compelling investment?
- Distribution reach: What institutional accounts does the bank have deep relationships with in your sector? The lead underwriter's book is only as strong as the accounts it can actually get orders from.
- Bankers, not the pitch: The managing directors who present in the bake-off are often not the people who work the deal daily. Ask who specifically will be running the transaction — and talk to that team directly.
- Recent IPO track record: How did the bank's recent deals in your sector perform? First-day return, 90-day return, and whether the stock is still covered by the analyst 12 months later are all signals.
Real-World IPO Team Dynamics
The composition and functioning of the IPO team can be as consequential as the company's fundamentals. These cases illustrate how advisor relationships play out in practice.
Snowflake — dual-lead with Salesforce/Berkshire anchors (September 2020): Snowflake's IPO team was led by Goldman Sachs and Morgan Stanley as co-lead underwriters — a common dual-lead structure for large technology offerings. What made Snowflake's team dynamics unusual was the announcement, on the day the roadshow launched, that Salesforce Ventures and Berkshire Hathaway were each making $250 million cornerstone investments at the IPO price. Having Warren Buffett — historically skeptical of technology IPOs — as a co-investor sent a powerful signal to institutional investors and contributed to the extraordinary demand. The lesson: the IPO team includes not just the underwriters but the quality of the cornerstone investor group that the lead underwriters can bring in.
Arm Holdings — 28-bank syndicate, largest in years (September 2023): Arm's $4.87 billion IPO involved a syndicate of 28 investment banks — one of the largest in recent memory. The wide syndicate reflected SoftBank's desire to maximize geographic distribution of Arm shares and build relationships with banks in key markets (US, UK, Japan, Taiwan, South Korea) where Arm's chip designs are extensively used. The lead managers were Goldman Sachs, JPMorgan, Barclays, and Mizuho. The unusual aspect: Mizuho, a Japanese bank, was given a prominent role reflecting SoftBank's Japanese investor base. This illustrates that underwriter selection is sometimes driven by strategic relationship considerations as much as by pure distribution capability.
WeWork — Goldman withdrawal and JPMorgan succession (2019): WeWork's IPO process featured a notable advisor drama: Goldman Sachs had been WeWork's primary banking relationship for years and was expected to serve as lead underwriter. As the S-1 drafting process advanced and the governance and financial concerns became clearer, Goldman's enthusiasm for the deal waned. JPMorgan, which had a competing relationship with WeWork, ultimately became the lead underwriter. When the roadshow was cancelled and the S-1 withdrawn, both Goldman and JPMorgan faced significant reputational questions about why they had agreed to underwrite an offering that institutional investors found so deeply problematic. The WeWork case is a reminder that underwriters have their own reputational interests and will sometimes push back on problematic disclosures or governance structures — but they also have significant fee incentives that can mute that pushback.
IPO Team Assembly — What Works and What Doesn't
Arm — 28-Bank Syndicate Reflects Global Distribution Need (2023)
The composition of Arm's 28-bank IPO syndicate reflected SoftBank's specific objectives: maximize post-IPO institutional shareholder coverage globally, ensure ongoing research coverage from a large number of sell-side analysts, and distribute fee income broadly enough to incentivize active deal marketing across multiple regions. The four co-leads (Goldman Sachs, JPMorgan, Barclays, Mizuho) handled the primary bookbuild and largest allocations. The next tier of bookrunners covered European institutional investors (Deutsche Bank, BNP Paribas, HSBC), Asian institutional investors (Daiwa, SMBC Nikko, China International Capital), and US mid-tier institutions. The breadth of the syndicate was unusual for a deal of this size — most $5 billion IPOs use 6–10 banks — and reflected SoftBank's priorities over pure fee efficiency. Companies with more concentrated investor targeting and fewer geographic requirements typically do better with smaller, more focused syndicates where each bank has a meaningful allocation to distribute and a real incentive to work the deal.
WeWork — Goldman Withdrawal Signals Team Breakdown
The implicit withdrawal of Goldman Sachs from its co-lead role in WeWork's 2019 IPO process illustrated how an IPO team can fracture when the underlying deal becomes unviable. Goldman had been deeply involved in WeWork's private financing history — it was an advisor on multiple rounds and had relationships with both WeWork and SoftBank. When the S-1 was filed and institutional investor reaction turned sharply negative, Goldman's ECM team began distancing itself publicly from the transaction. JPMorgan, also a co-lead, stayed engaged and ultimately provided the rescue financing after the IPO was cancelled. The differential behavior of the two lead banks was closely observed by the institutional investor community: Goldman's withdrawal was read as a signal from an insider that the deal was not salvageable, while JPMorgan's continued engagement reflected its banking relationship with SoftBank.
Snowflake — CEO Credibility as a Team Asset
One underappreciated element of Snowflake's exceptional IPO outcome was the credibility of CEO Frank Slootman in the institutional investor community. Slootman had previously taken ServiceNow public in 2012 and grown it into a $100+ billion market cap company — making him one of a small number of CEOs who had successfully navigated the IPO process and the subsequent years of public company management before. When institutional investors attended Snowflake's roadshow meetings, they were not evaluating an untested CEO — they were evaluating a proven operator with a track record of post-IPO value creation. The Slootman factor was genuinely significant in Snowflake's bookbuild: long-only funds that might have been skeptical of a pre-profitability enterprise software company were comfortable making large commitments because of their confidence in Slootman's operational execution ability. The lesson for private companies preparing for IPO: CEO credibility and track record are legitimate components of the IPO team's strength.
When to Engage Each Advisor
The sequencing of advisor engagements is as important as the selection. Engaging advisors too early wastes fees; too late creates preparation gaps that cannot be closed before the S-1 filing deadline.
| Advisor | Engagement Timing | Why This Timing |
|---|---|---|
| PCAOB Auditor | 18–24 months before target IPO | Needs to audit two full fiscal years before S-1 filing; changing auditors mid-process is highly disruptive |
| Accounting Advisory Firm | 18 months before target IPO | ASC 606/842/805 implementations, SOX readiness, and close process improvements take 12+ months to complete |
| IPO Counsel (company) | 12 months before target IPO | Corporate governance restructuring, equity plan preparation, and preliminary S-1 drafting work begins 6–9 months before filing |
| Underwriter Selection | 6–9 months before target IPO | Allows time for testing-the-waters meetings before the formal roadshow; the bake-off process itself takes 4–6 weeks |
| D&O Insurance Broker | 9–12 months before target IPO | Program design takes 3+ months; binding coverage requires completed S-1 and board approval |
| Investor Relations Firm | 9–12 months before target IPO | Equity story development, analyst targeting, and IR website build take 6+ months |
| Transfer Agent | 6 months before target IPO | Operational setup and DTCC registration take several months; existing equity records must be migrated |
| Financial Printer | 3–6 months before target IPO | Platform setup and team onboarding needed before S-1 drafting begins in earnest |
IPO Project Management
The IPO process involves 8–10 advisor teams working in parallel across dozens of parallel workstreams. Without effective project management, critical dependencies are missed and timelines slip. Best practices:
- Weekly all-hands drafting calls: All advisors join a weekly update call throughout the S-1 drafting period — IPO counsel, company, underwriter counsel, auditors, and financial printer. These calls maintain pace, surface interdependencies, and ensure everyone is working from the same version of the document.
- Master workstream tracker: A shared project management document (typically maintained by IPO counsel) lists every workstream, the owner, the status, and the deadline. Updated weekly and reviewed on the all-hands call.
- IPO readiness dashboard: Senior management reviews a dashboard weekly showing the status of each readiness workstream — accounting, SOX, governance, D&O, data room, IR. Red/yellow/green status makes escalation decisions easy.
- SEC filing logistics: The financial printer coordinates the actual EDGAR filing — timing, exhibits, XBRL tagging, and format review. Plan for a 24–48 hour filing window; unexpected document preparation issues regularly cause delays at this stage.
Building the Internal IPO Team
External advisors execute the IPO, but the internal team owns the company's narrative and the accuracy of every disclosure. Companies that do not build adequate internal capacity to manage the IPO process typically experience delays, disclosure errors, and post-IPO control deficiencies. Core internal roles needed:
- CFO: Owns the financial narrative, the MD&A, the non-GAAP policy, and the overall S-1 process. Should have public company experience if possible.
- Chief Accounting Officer / Controller: Owns the technical accounting workstreams, the financial statements, and the interface with the auditors. A critical hire if the company does not have one — should be hired 18 months before the IPO.
- General Counsel: Owns the legal diligence workstreams, governance restructuring, insider trading policy, and the interface with IPO counsel.
- Head of Investor Relations: Can be hired 12 months before IPO or outsourced to the IR firm initially. Owns the equity story, the IR website, the earnings process, and the investor targeting program.
- VP Finance / FP&A: Owns the financial model that underlies guidance, the non-GAAP reconciliations, and the financial data quality for the S-1 tables.
