What is Investment Banking?

Investment banking is a financial service that acts as an intermediary between companies and capital markets. Investment banks advise corporations, governments, and institutions on complex financial transactions including mergers and acquisitions, IPOs, debt offerings, and restructurings. They don't invest their own capital but rather facilitate deals and provide strategic advisory services for fees.

Core Services:

  • • Mergers & Acquisitions (M&A) advisory
  • • Capital raising (equity and debt)
  • • IPO underwriting and execution
  • • Financial restructuring and bankruptcy advisory
  • • Valuation and fairness opinions
  • • Strategic advisory and market insights

What is Private Equity?

Private equity is an investment model where firms pool capital from institutional investors and high-net-worth individuals to acquire controlling stakes in private companies. Unlike investment banks, PE firms deploy their own capital and actively work to improve portfolio companies' operations, strategy, and profitability over 3-7 years before selling for a return.

Core Activities:

  • • Acquiring majority or controlling stakes in companies
  • • Leveraged buyouts (LBOs) and growth equity investments
  • • Operational improvements and cost optimization
  • • Strategic repositioning and add-on acquisitions
  • • Board governance and management oversight
  • • Exit strategy execution (IPO, strategic sale, secondary)

Key differences between Private Equity and Investment Banking
Understanding the main distinctions

Capital Commitment

Investment banks provide advisory services without deploying their own capital, acting as intermediaries. Private equity firms commit significant capital from their funds, taking on substantial risk and ownership stakes in companies.

Time Horizon

IB engagements are transaction-based, lasting 3-12 months from mandate to close. PE investments are long-term commitments spanning 3-7 years, requiring sustained involvement to create value.

Revenue Generation

Banks earn advisory and underwriting fees tied to transaction completion. PE firms generate returns through management fees and carried interest based on portfolio company performance and successful exits.

Client Relationship

Investment banks serve multiple clients simultaneously with transactional relationships. PE firms become partners and majority owners, working closely with management teams to drive operational and strategic improvements.

Value Creation Approach

Banks create value through deal structuring, optimal pricing, and efficient execution. PE firms drive value through operational improvements, strategic repositioning, add-on acquisitions, and leveraged returns.

Regulatory Environment

Investment banks face extensive SEC regulation, capital requirements, and public disclosure obligations. PE firms have lighter regulatory oversight but must comply with Dodd-Frank, SEC registration (if over $150M AUM), and LP reporting requirements.

Investment Banking Data Rooms

Investment banks use virtual data rooms as the central hub for M&A transactions, IPOs, and capital raises. These secure platforms enable buyers and investors to conduct due diligence efficiently while maintaining confidentiality and control.

Key Use Cases:

  • Buy-side & Sell-side M&A: Organize financial statements, contracts, customer data, and legal documents for buyer due diligence
  • IPO Document Management: Manage prospectus documents, regulatory filings, and investor materials during roadshows
  • Capital Raising: Share confidential information memorandums (CIMs) with potential investors and track engagement
  • Deal Analytics: Monitor which documents investors review most, identify concerns early, and optimize deal timing

Private equity VDR

PE firms rely on a VDR throughout the entire investment lifecycle — from initial due diligence to portfolio company management and exit preparation. A VDR for private equity provides security, organization, and analytics at every stage, helping teams prioritize opportunities and protect sensitive information.

Key Use Cases:

  • Buy-side due diligence in a VDR: Review target company documents across financial, legal, operational, and commercial workstreams
  • Portfolio company management: Centralize board materials, monthly reports, and strategic plans for portfolio oversight
  • Add‑on acquisition tracking: Evaluate multiple acquisition targets simultaneously with organized deal pipelines
  • Exit preparation: Prepare comprehensive rooms for buyers showcasing portfolio performance and growth

Frequently asked questions
Common questions about PE and IB services

Can a company work with both an investment bank and private equity firm?

Yes, this is common. An investment bank might advise your company on a sale process where the buyer is a private equity firm. Or, a PE-backed company might hire an investment bank to execute add-on acquisitions or prepare for an eventual exit through IPO or strategic sale.

How much does it cost to work with an investment bank vs private equity?

Investment banks typically charge 1-7% of transaction value depending on the service (M&A, IPO, debt financing). Private equity doesn't charge companies directly for capital - instead, they invest their fund's capital for an equity stake. PE-backed companies may pay ongoing monitoring fees ($500k-$2M+ annually) to the PE firm.

Do investment banks invest in companies like private equity firms?

No. Investment banks are advisors and intermediaries who facilitate transactions for fees but don't deploy their own capital into companies (except briefly during IPO underwriting). Private equity firms are principal investors who commit their fund's capital to acquire ownership stakes and drive value creation over multiple years.

Should I raise growth capital from private equity or use an investment bank to find strategic investors?

It depends on your goals. PE is ideal if you want operational expertise, board support, and a long-term partner (usually requires giving up majority control). Use an investment bank if you want to run a competitive process, maintain more control, or need help identifying and negotiating with multiple potential investors (strategic or financial).

What's the typical timeline for working with each?

Investment banking engagements are transaction-focused and typically last 6-12 months from mandate to close. Private equity relationships are long-term partnerships spanning 4-7 years from initial investment through exit. PE firms remain actively involved throughout the holding period, while banks exit once the transaction closes.
