Gamma for Investment Banking: What Advisors Need

Gamma is one of the most capable general AI presentation tools available today. If you need to turn a rough outline into polished slides in ten minutes, Gamma delivers. But if you’re an M&A advisor preparing a sell-side pitchbook, a CIM, or a management presentation for a board, Gamma creates the illusion of progress while leaving the hard work untouched.

Investment bankers evaluating AI presentation tools frequently land on Gamma. It’s fast, it’s beautiful, and it’s widely recommended. The problem is that none of those qualities address what makes pitchbook production difficult.

Tools like Bookbuild are built for exactly this gap — automating the deal research, comp selection, valuation framing, and slide production pipeline that Gamma can’t touch. Request early access →

What Gamma Actually Does Well

Before comparing tools unfairly, it’s worth being honest about Gamma’s strengths.

Gamma excels at:

• Converting rough text into structured slide decks
• Applying consistent visual themes and typography
• Iterating on presentation narrative with conversational prompts
• Producing slides quickly for internal pitches, updates, and reports

For a junior analyst who needs to prepare a market update for a Monday morning call, Gamma is genuinely useful. For a VP who needs to rework a board presentation overnight, Gamma saves hours.

These are real use cases, and Gamma handles them better than most tools. The issue arises when advisors assume those capabilities extend to deal marketing documents.

Why Investment Banking Pitchbooks Are Different

A pitchbook is not a presentation. It is an investment banking deliverable — and that distinction matters enormously.

A sell-side pitchbook typically includes:

• Company overview — business description, revenue mix, customer concentration, management depth
• Financial profile — LTM revenue, EBITDA, adjusted EBITDA, growth trajectory
• Comparable company analysis (comps) — public trading multiples for peer companies, drawn from deal databases
• Precedent transaction analysis — prior M&A deal multiples in the relevant sector
• Valuation summary — football field showing methodology ranges
• Buyer universe — strategic and financial acquirers with acquisition rationale
• Process overview — timeline, diligence expectations, deal structure considerations
• Appendix — detailed financials, management bios, operational data

Gamma can format slides around these headings. What it cannot do is populate them.

A comparable company analysis requires access to live market data — EV/EBITDA multiples, revenue multiples, enterprise values — for a specific peer group in a specific sector. Gamma has no access to Capital IQ, Refinitiv, or deal databases. It cannot pull comps. It cannot identify relevant precedent transactions. It cannot build a defensible valuation range.

The research that makes a pitchbook credible — and that clients actually pay for — has to be done elsewhere. That means advisors using Gamma still spend most of their time on the work Gamma cannot touch.

The Workflow Problem: What Gamma Doesn’t Solve

When advisors describe the pitchbook process, the bottleneck is rarely formatting. It is:

1. Pulling comparable companies from a deal database and cleaning the data
2. Running precedent transaction screens across relevant M&A deals
3. Constructing the valuation football field across multiple methodologies
4. Building a qualified buyer universe of strategic and financial acquirers
5. Structuring the sell-side narrative in a format clients and their boards understand

A tool that helps you make slides faster does not address any of these five steps. It accelerates the last mile — visual presentation — while leaving the actual work intact.

In a McKinsey analysis of professional services automation, the tasks that take the most time in knowledge work are precisely the ones that require domain-specific data access and analytical judgment — not the tasks that require formatting or communication. Investment banking pitchbook production follows this pattern exactly.

What Gamma Looks Like in Practice for M&A Advisors

Here is a typical scenario at a boutique advisory firm:

An advisor wins a mandate to run a sell-side process for a mid-market industrial company. They need to deliver a pitchbook to the seller within ten days.

Using Gamma, the advisor can:

• Generate a slide deck outline from a narrative brief
• Apply the firm’s visual theme
• Draft company overview narrative from a provided document

Using Gamma, the advisor still has to:

• Pull comps manually from Capital IQ or Bloomberg
• Build the financial model and valuation ranges in Excel
• Research and qualify the buyer universe manually
• Assemble all of this into slide-ready format by hand
• Proofread, adjust, iterate based on partner feedback

The formatting savings are real but marginal. The research and analytical work — which typically represents 70–80% of pitchbook production time — remains unchanged.

What a Purpose-Built Pitchbook Tool Does Instead

Tools designed specifically for M&A advisors approach the problem from the opposite direction. Instead of starting with slides, they start with the data.

Bookbuild, for example, is built on a proprietary dataset of 332,000 deal comps and 120,000 buyer profiles sourced from Capital IQ. An advisor inputs the target company — sector, size, financial profile — and the system:

• Identifies a qualified set of comparable public companies and precedent transactions
• Pulls relevant trading and deal multiples
• Generates a structured buyer universe across strategic and financial acquirers
• Assembles the pitchbook narrative around the client’s specific situation
• Produces client-ready slides in the firm’s preferred format

The compression is not in the formatting step. It is in the research and assembly pipeline that consumes most of the advisor’s time. The result is a pitchbook that takes hours to produce rather than the 1–2 weeks that manual processes require — and that can withstand client scrutiny because the underlying data is defensible.

This is a fundamentally different capability from what Gamma offers. One automates slide formatting. The other automates investment banking workflow.

When Gamma Is Worth Using Alongside a Pitchbook Tool

Gamma is not the wrong tool — it is a tool for the wrong problem when used for pitchbook production. There are contexts where advisors find genuine value in Gamma:

• Internal presentations — market updates, pipeline reviews, fund performance summaries
• Non-deal advisory — strategic planning decks, board governance updates, market entry analyses
• Quick client communications — project kickoff decks, process timeline summaries
• Final polish — after the analytical content is finalized, Gamma can help improve visual consistency

In these contexts, the limitation — lack of deal data — does not matter because the content does not require it. Advisors who use Gamma for light-touch communications and a purpose-built tool for deal documents get the benefit of both.

The mistake is trying to use Gamma as a substitute for the actual investment banking work in pitchbook production.

Evaluating Pitchbook Software for M&A Advisors

When evaluating tools for pitchbook and CIM production, the right questions are:

1. Does the tool have access to deal data? Comps and precedent transactions require a live data source. If the tool has no database integration, you are still doing that work manually.

2. Does the tool understand M&A document structure? Pitchbooks, CIMs, management presentations, and deal teasers have different structures, purposes, and audiences. A general presentation tool treats them all as slides.

3. Can the tool build a buyer universe? Identifying qualified acquirers — with strategic rationale and contact information — is one of the highest-value steps in a sell-side process. General tools cannot do this.

4. Does it produce client-ready output? The end product needs to be something you can put in front of a seller, a board, or a prospective buyer without rebuilding it from scratch.

5. Does it save time on the right tasks? Formatting is five percent of the problem. If a tool only saves time on formatting, it saves five percent of the time.

The Bottom Line for Investment Bankers

Gamma is a well-designed tool that does what it promises: it helps you make better-looking presentations faster. For many use cases in finance, that is genuinely valuable.

For investment banking pitchbooks and deal marketing documents, it does not address the actual workflow bottleneck. The research, the data, the comps, the buyer analysis — those remain unchanged.

If you are evaluating tools to compress your pitchbook production timeline in a meaningful way, the question to ask is not “can this tool make my slides look better?” but “can this tool do the investment banking work that makes my slides worth reading?”

Purpose-built M&A tools answer that question differently than general presentation AI. The distinction is worth understanding before you invest time trying to adapt a general tool to a specialized workflow.

FAQ

Can Gamma be used to make investment banking pitchbooks? Gamma can produce visually polished presentations, but it lacks M&A-specific components bankers need — deal comps, valuation analysis, transaction data, and structured sell-side narrative — so most advisors still build those elements manually.

What are the limitations of Gamma for M&A presentations? Gamma has no access to deal databases, no comparable company analysis engine, no CIM or teaser structure templates, and no understanding of M&A deal flow. It is a general AI presentation builder, not an investment banking workflow tool.

What is a better alternative to Gamma for pitchbooks? Purpose-built tools like Bookbuild are designed specifically for M&A advisors — they include deal comps, buyer identification, CIM structure, and branded pitchbook output. The workflow is tailored to how sell-side advisors actually work.

How long does it take to build a pitchbook in Gamma? Gamma can generate slides in minutes, but without deal data, comps, or M&A-specific structure, advisors still spend days on research, valuation, and buyer analysis before producing anything suitable for a client mandate.

Is Gamma worth using for junior banker presentations? Gamma can accelerate internal presentations, market updates, or board-level summaries where structure is flexible. It is not a fit for client-facing M&A mandates, sell-side pitchbooks, or CIM preparation where deal-specific accuracy matters.
