The Challenge: Manual Prospect Research
For most B2B sales teams, manual prospect research is an invisible tax on performance. Reps spend hours every week googling companies, scanning LinkedIn profiles, opening annual reports and copying snippets into CRM notes before they even send the first email. Each new account or contact requires another round of repetitive, low-leverage work that doesn’t directly move deals forward.
Traditional approaches rely on reps juggling browser tabs, generic data providers and outdated internal spreadsheets. Even with a good CRM, the data is often incomplete, inconsistent or old. Reps build their own “systems” in personal notes, bookmarks and ad-hoc templates. The result: research is slow, quality depends on the individual rep, and there is no scalable, repeatable way to keep prospect intelligence up to date.
The business impact is significant. Every hour spent on manual research is an hour not spent on live conversations, discovery or closing. Lead generation capacity is capped by how quickly humans can research accounts. In competitive markets, this means slower response times to inbound leads, missed triggers such as funding rounds or leadership changes, and lower-quality outreach because messages are built on incomplete information. Over a quarter or a year, this compounds into lost pipeline, lower conversion rates and a clear competitive disadvantage.
The good news: this problem is highly solvable. Advances in AI for sales prospecting and tight integration of tools like Gemini in Google Workspace make it possible to automate large parts of research while actually improving data quality. At Reruption, we’ve helped organisations replace manual document and web research with AI-powered assistants and internal tools. In the rest of this guide, we’ll walk through concrete ways to apply the same thinking to your prospect research workflow — so your reps can focus on selling, not surfing the web.

Our Assessment
A strategic assessment of the challenge and high-level tips how to tackle it.
From Reruption’s work building AI-powered research and automation tools inside complex organisations, we’ve seen the same pattern repeatedly: sales teams don’t need more data, they need a smarter way to turn scattered information into concise, actionable prospect intelligence. Gemini for prospect research is powerful precisely because it sits inside Google Workspace, close to where your reps already work in Gmail, Sheets and Docs, and can combine web results with your internal knowledge to accelerate lead generation without adding another standalone tool.
Define a Clear Prospect Research Operating Model Before You Automate
Before turning Gemini loose on the web, define what "good" research actually means for your sales organisation. Many teams jump straight into prompts without aligning on the minimum data set needed for outreach: target industries, decision-maker roles, buying triggers, key technologies, and disqualifying factors. Without this shared operating model, each rep will use Gemini differently and you lose the consistency that makes automation valuable.
Document a simple, standard prospect brief structure with sections like company overview, ICP fit, key initiatives, recent news, tech stack, and suggested angles. Align sales, marketing and RevOps on this template. Once this is clear, Gemini can be configured to consistently produce research aligned with your ideal customer profile instead of a generic company summary.
Start with Narrow, High-Impact Use Cases
A common failure mode is trying to make Gemini handle every aspect of sales research and lead generation on day one. Strategically, it’s better to start with 1–2 high-impact workflows where manual effort is clearly visible: preparing briefs for outbound target accounts, enriching inbound leads, or updating stale account notes before renewal cycles. This allows you to measure impact and refine prompts before rolling out organisation-wide.
Pick a specific segment (e.g., mid-market accounts in one region) and instrument the process: time spent per account before and after, number of accounts researched per week, and downstream metrics like meeting booked rate. This narrow focus builds internal proof points and shows your team that AI for manual prospect research is a practical, not theoretical, improvement.
Treat Gemini as Part of the Sales Stack, Not a Side Experiment
To realise real value, Gemini has to be integrated into your sales process and tooling, not sit as an interesting AI demo only a few power users touch. Strategically map where prospect research lives in your funnel: list building, account planning, sequence preparation, and territory coverage reviews. Then decide exactly where Gemini should plug into each step: generating first-pass research in Sheets, summarising discovery calls stored in Drive, or drafting personalised outreach in Gmail.
Involve Sales Ops and IT early so permissions, data access and governance are designed deliberately. This avoids shadow workflows and ensures your AI-powered prospect research aligns with CRM fields, reporting and approval flows. When Gemini is treated as a first-class component of your sales stack, adoption and ROI increase substantially.
Prepare Your Team for a Shift from Gathering to Judging
With Gemini handling much of the repetitive information gathering, the role of the sales rep shifts towards judging information quality, validating fit and choosing the right outreach angle. This is a mindset change. Strategically, you need to train reps to review and refine AI output quickly rather than recreate research from scratch. That includes teaching them how to give better prompts, spot hallucinations and apply domain knowledge to adjust suggestions.
Plan enablement sessions that show concrete before/after workflows: "here is how you did prospect research last quarter, here is how you’ll do it with Gemini." Emphasise that AI-assisted research is not about replacing judgement, but about giving them more time for conversations and strategy. The organisations that win are those where reps lean into this new division of labour instead of fighting it.
Build in Guardrails, Feedback Loops and Compliance from Day One
As with any AI deployment in sales, you need to consciously design guardrails and feedback loops. Strategically decide what types of data Gemini is allowed to use and store, especially when combining internal documents with web content. For regulated industries or sensitive accounts, you may want stricter configurations. Work with legal and security teams to define acceptable sources and ensure that no confidential customer information is being exposed.
At the same time, set up simple feedback mechanisms so reps can flag incorrect or low-quality research. That might be as easy as a shared form or a dedicated Slack channel. The goal is to continuously refine prompts, templates and data sources. At Reruption, we’ve seen that teams who treat Gemini deployment as an evolving product, not a one-off rollout, achieve much better outcomes and avoid "AI fatigue" after the initial excitement fades.
Used deliberately, Gemini can turn manual prospect research from a bottleneck into a scalable capability, freeing reps from low-value googling and letting them focus on qualified conversations. The key is not just the model, but how you embed it into your research operating model, tech stack and team habits. Reruption combines deep AI engineering with hands-on sales process design to help organisations make that shift quickly and safely — if you’re exploring how Gemini could transform your lead generation workflow, we’re happy to pressure-test your ideas and design a first implementation step that actually ships.

Best Practices
Successful implementations follow proven patterns. Have a look at our tactical advice to get started.
Standardise a Prospect Brief Template in Google Docs
Start by creating a shared Prospect Brief template in Google Docs that reflects your ICP and sales motion. Include sections for company overview, key metrics (employees, funding, locations), ICP fit rationale, recent news and events, current tools or tech stack, and suggested messaging angles. This structure gives Gemini a consistent target format and reduces variability between reps.
Once the template is in place, use Gemini inside Docs to populate it from a minimal input like company name and website. A rep can paste 1–2 URLs and a short description of the target persona, then invoke Gemini to fill the sections with summarised information and links to sources for quick verification.
Example Gemini prompt in Google Docs:
You are a sales research analyst.
Fill out this Prospect Brief for the company <COMPANY NAME> using the structure in this document.
Focus on:
- What the company does and who they serve
- Signals that they match our ICP: <briefly describe ICP>
- 3–5 recent events or news items that matter for a sales conversation
- Their current tools/tech stack if visible
- 3 tailored messaging angles we could use in outreach
Only include information you can reasonably infer from the website and recent public sources. If something is unclear, state "Unknown" rather than guessing.
Expected outcome: consistent, high-quality briefs in 3–5 minutes instead of 20–30 minutes of manual research, with better coverage of relevant triggers and initiatives.
Use Sheets + Gemini to Enrich and Prioritise Lead Lists
When working from exported lead lists (events, webinar signups, basic CRM lists), bring them into Google Sheets and use Gemini for bulk enrichment and scoring. Add columns for target attributes such as "ICP Fit", "Priority Tier", "Key Trigger" and "Suggested Outreach Angle". With Gemini in Sheets, you can enrich multiple rows in a guided way instead of handling each contact manually.
Provide Gemini with a compact description of your ICP and a few examples of what high, medium and low fit entries look like. Then run it on subsets of your sheet to classify and prioritise. Always keep a manual review step for top-tier accounts to ensure quality.
Example Gemini prompt in Google Sheets (cell note or side panel):
You are assisting with lead qualification.
Based on the company name, job title, and website in this row, do the following:
1. Rate ICP Fit as High, Medium, or Low based on this ICP description: <paste ICP>.
2. Identify one likely buying trigger (e.g., rapid hiring, expansion, digital transformation).
3. Suggest a 1-sentence outreach angle referencing that trigger.
Answer in the format:
ICP Fit | Trigger | Outreach Angle
Expected outcome: a prioritised lead list that directs reps towards high-fit accounts, increasing conversion rates from outreach while reducing time wasted on poor fits.
Automate Pre-Call and Pre-Outreach Research from Gmail
Reps often jump into calls or send follow-ups without a quick refresh of the latest updates on an account. Use Gemini in Gmail to generate concise, contextual research summaries directly from the email thread and web. When a prospect reaches out, the rep can ask Gemini to summarise the company, key stakeholders in the thread and relevant public updates before drafting a reply.
This is particularly useful for inbound leads and multi-threaded conversations where context is scattered. Gemini can surface the last 2–3 major news items and suggest talking points tailored to the buyer’s role, directly in the email composer.
Example Gemini prompt in Gmail:
You are preparing a sales rep for a response.
Based on this email thread and public information about the sender's company:
1. Summarise the company's business in 2–3 bullet points.
2. List 3 recent events or news items that could influence their priorities.
3. Suggest 3 tailored talking points for a reply, aligned with the sender's role: <job title>.
Keep it concise enough for the rep to absorb in under 60 seconds.
Expected outcome: better-tailored responses and discovery questions with almost no extra prep time, leading to higher meeting quality and win rates.
Create Territory Research Packs with Drive and Gemini
Sales leaders can use Gemini with Google Drive to build "territory intelligence packs" that aggregate internal and external knowledge for each region or segment. Store relevant market reports, previous proposals, case studies and customer call notes in structured folders per territory. Then use Gemini to generate summary docs that highlight common pain points, successful messaging, and typical buyer journeys for that territory.
New reps ramping into a territory can use these packs as a starting point for their own prospecting, while Gemini can also be prompted to propose a ranked list of accounts to research next based on your ICP and public firmographic data.
Example Gemini prompt in Google Docs (for a territory pack):
You are analysing this folder of documents and public web information for the DACH mid-market manufacturing segment.
Create a Territory Intelligence Summary that includes:
- 5–7 common challenges these companies face related to <your solution area>
- Patterns from our past proposals and notes in Drive
- Example language and phrases prospects use to describe their problems
- A short list of example account profiles that are "ideal" for outreach
Use bullet points and keep the document under 2 pages.
Expected outcome: faster ramp time for new reps, more consistent messaging across the team, and a structured base for focused prospect research in each territory.
Build Reusable Prompt Snippets for Different Buyer Personas
To make Gemini-powered prospect research repeatable, create a library of prompt snippets tailored to your key buyer personas (e.g., CRO, CIO, Head of Operations). Each snippet should instruct Gemini how to interpret public information through the lens of that persona’s priorities and language, so the output feels highly relevant when reps prepare outreach or calls.
Host these snippets in a shared internal doc or knowledge base and train reps to copy-paste and adapt them. Combining company research prompts with persona-specific instructions leads to better talking points and more compelling messaging angles than generic "tell me about this company" queries.
Example persona research snippet:
You are preparing a brief for outreach to a <JOB TITLE, e.g. VP of Sales> at <COMPANY>.
Based on the company's website and recent news:
- Identify 3–5 priorities that a VP of Sales in this company is likely to care about.
- Map each priority to how our solution (high-level: <one-sentence description>) could help.
- Suggest 3 email subject lines and 3 opening sentences that speak directly to those priorities.
Use the prospect's language where possible (quoting phrases from their site).
Expected outcome: higher reply rates and more relevant conversations because outreach is grounded in both company context and persona-specific value drivers.
Track Impact with Simple, Concrete Metrics
To ensure your Gemini prospect research initiative delivers real value, define and track a small set of KPIs from the start. At minimum, measure: average time spent on research per account, number of new accounts or contacts researched per rep per week, outbound reply rate, and meetings booked per 100 contacts touched. Capture a baseline for 2–4 weeks before rollout, then compare after adoption stabilises.
Use this data to refine prompts, templates and training. If research time drops but reply rates fall as well, you may have over-optimised for speed at the expense of depth. If reply rates improve but research time stays high, look for additional automation opportunities in your workflow. Treat these metrics as input for continuous improvement, not just a one-time success benchmark.
Expected outcomes when implemented well: 40–60% reduction in manual research time per prospect, 2–3x more accounts touched per rep per week, and 10–25% improvements in outbound reply or meeting-booked rates over a few months — realistic gains that compound into significantly stronger pipeline without increasing headcount.

Frequently Asked Questions
Gemini streamlines the repetitive parts of prospect research by working directly inside Google Workspace. Reps can use Gemini in Docs to auto-generate prospect briefs from a company name and website, in Sheets to enrich and prioritise lead lists, and in Gmail to surface company summaries and recent news while they write emails.
Instead of opening multiple tabs, copying information into notes and trying to remember ICP criteria, reps prompt Gemini to create a structured overview in minutes. They still review and adjust the output, but the heavy lifting of finding and summarising information is automated, typically cutting research time per account from ~20–30 minutes to a few minutes.
You don’t need a data science team to start using Gemini for sales prospecting, but you do need three things: clear ICP and research criteria, basic Google Workspace administration, and someone to own prompt and template design. Sales Ops or a technically inclined sales manager can usually take this role.
From there, implementation is mostly about workflow design and enablement: creating shared Docs and Sheets templates, configuring access and permissions, and training reps on how to use Gemini effectively and responsibly. Reruption often pairs with a small internal squad (Sales, Sales Ops, IT) to co-design these workflows and turn them into a working prototype within weeks.
For most teams, initial productivity gains appear within 2–4 weeks if you focus on one or two well-defined workflows (e.g., outbound account briefs and lead list enrichment). Reps quickly feel the time savings as they prepare outreach and meetings.
Pipeline and conversion impacts typically show up over a slightly longer horizon — expect 1–3 months to see clear trends in metrics like meetings booked per rep or outbound reply rates. The key is to start small, measure before/after, and iteratively refine prompts and templates based on rep feedback and performance data.
Gemini is licensed through Google, often as an add-on to existing Google Workspace subscriptions. The direct cost depends on your plan and number of users, but the main ROI driver is time saved and improved lead quality, not the licence fee itself.
In practical terms, if a rep spends 5–10 hours per week on manual research, cutting that in half effectively adds several "new" selling hours without increasing headcount. When combined with better targeting and messaging (higher reply and meeting rates), it’s realistic to see 40–60% less time spent on research and 10–25% better outbound performance over time. That ROI usually dwarfs the tooling cost, provided you implement Gemini into your core workflows instead of keeping it as a side experiment.
Reruption works as a Co-Preneur inside your organisation: instead of only advising, we help design and ship a working AI-powered prospect research workflow with your team. Our AI PoC offering (9.900€) is designed exactly for this kind of use case — we define the research workflow, assess technical feasibility with Gemini and Google Workspace, and build a functioning prototype that your reps can test in real life.
From there, we support you in refining prompts and templates, integrating outputs into your CRM, and putting the necessary security and compliance guardrails in place. Because we focus on engineering and execution, you end up not with slideware, but with a live system your sales team actually uses to generate more and better leads.
