How strategy teams can use AI market sizing with Manus

Manus turns scattered market research into structured estimates and reusable sizing workflows across markets, segments, and scenarios.

Opportunity sizing for new bets

Estimate whether a new product line, feature, or market deserves attention before committing time, budget, or headcount.

Segment prioritization

Compare SMB, mid-market, and enterprise opportunities to see which customer segment offers the clearest path to growth.

Geographic expansion planning

Test how average contract value, packaging, and conversion assumptions affect serviceable and obtainable market estimates with an AI price estimation tool.

Start with a strong prompt, then get more specific

A practical market sizing prompt should define the market, geography, buyer segment, and method, then tell Manus how to present the estimate, assumptions, and decision-ready output.

Define the market, geography, and buyer segment clearly
Ask for TAM, SAM, and SOM plus the sizing method used
Request assumptions, evidence, and a structured final output

Use prompt templates for specific goals

General market sizing: estimate the TAM, SAM, and SOM for our category, explain the sizing method, and list every major assumption.
Segment comparison: compare the market size for SMB, mid-market, and enterprise buyers, then explain where the best growth opportunity sits.
Geographic expansion: estimate the market size for this category across the united states, europe, and southeast asia and explain how the assumptions differ.
Pricing scenario planning: show how different pricing levels and contract values change the SAM and SOM for this product.
Investor memo: turn the market sizing analysis into a short memo with TAM, SAM, SOM, assumptions, risks, and a recommendation.
Top-down method: use public market data, adoption signals, and industry benchmarks to estimate the TAM for this category.
Bottom-up method: use buyer counts, contract value assumptions, and segment penetration to build a bottom-up market estimate.
Method comparison: compare top-down and bottom-up market sizing for this product and explain where the two estimates diverge.

AI market sizing tool FAQ

What is an AI market sizing tool?

An AI market sizing tool helps teams estimate the size of an opportunity by combining customer, pricing, segment, and adoption assumptions into a structured view of the market. It speeds up research, organizes the logic, and makes the final estimate easier to review.

How does Manus help with market sizing?

Manus helps with market research, method comparison, assumption tracking, and structured outputs, so the final estimate is easier to review and use in planning, strategy, and investor discussions. It is especially useful when the workflow needs both research depth and reusable deliverables.

What should I give Manus before I start?

Provide the market, geography, customer segment, known pricing or adoption assumptions, and the output format you want, such as a table, memo, or planning summary. The clearer the scope and evaluation criteria, the more useful the market sizing output becomes.

Can Manus compare TAM, SAM, and SOM methods?

Yes. You can ask Manus to compare top-down and bottom-up approaches, explain the assumptions behind each one, and show where the estimates differ. That makes it easier to understand whether the opportunity depends on market definition, pricing logic, or adoption expectations.

Is this useful for startups?

Yes. Startups can use Manus to build an initial market sizing model faster, especially when they need a first-pass view before a deeper analyst-led process. It can also help founders test adjacent markets and prepare clearer materials for investors or partners.

Can this support investor or board work?

Yes. Manus can turn the research and estimates into clearer tables, summaries, and research-backed business proposals that are easier to review with investors, boards, or internal leadership. It works well when you need an explainable estimate rather than a black-box number.
