Hello! Welcome to your next lesson in building a powerful go-to-market engine.
In our last lesson, you created a playbook for engaging with niche communities on Reddit. You learned how to provide immense value non-promotionally, building credibility and attracting early users through an indirect funnel. That "pull" strategy is foundational. Today, we're adding a powerful "push" strategy to your arsenal: influencer marketing.
Instead of only participating in conversations, you'll learn how to identify and partner with the people who already have the trust and attention of your ideal customers. We'll focus specifically on micro-influencers—creators with smaller, highly-engaged, and niche audiences who can be potent allies for an early-stage SaaS.
Your learning outcome for this lesson is to use SparkToro to identify and vet a list of 10-15 potential micro-influencers for collaboration. This is a highly tactical skill that will allow you to precisely target your outreach efforts and get your product in front of the right people.
Why Micro-Influencers?
Before we dive into the "how," let's quickly clarify the "what" and "why." What makes a micro-influencer so valuable for a startup? It boils down to trust and engagement.
6 Ways To Find Micro Influencers On Instagram, TikTok & YouTube
The video '6 Ways To Find Micro Influencers' from Modash provides a concise explanation of the value of micro-influencers.
Watch the first minute (00:00 to 00:57) to understand what micro-influencers are and why their high engagement rates make them so effective for marketers.
As the video highlights, creators with fewer followers often have significantly higher engagement rates. Their recommendations feel more like a trusted peer's advice than a paid celebrity endorsement. For a new SaaS, this authentic connection is marketing gold.
Introducing SparkToro: Your Audience Intelligence Engine
To find these valuable micro-influencers, we will use a specialized tool: SparkToro.
It's crucial to understand that SparkToro is not just a database of influencers. It is an audience intelligence platform. Its core function is to answer the question: "What does my target audience pay attention to?" This is a fundamental shift from simply looking for people with high follower counts.
Audience Intelligence, on Steroids with Rand Fishkin
In this transcript from the Marketing Speak podcast, SparkToro's founder, Rand Fishkin, explains the unique philosophy behind the tool. Understanding this will help you use it much more effectively.
Read the section that begins with 'It’s really strange that people go after a high follower account...' and ends just before 'Right. In other words...'. Pay close attention to how Rand contrasts SparkToro's approach (starting with the audience) with traditional tools (starting with a list of journalists or influencers).
By focusing on the audience first, you ensure that any influencer you find is, by definition, relevant to your potential customers. This is the key to efficient and effective partnership outreach.
Step 1: Defining Your Audience in SparkToro
Your first step in SparkToro is to tell it who your audience is. The more precisely you can define this group, the better your results will be. SparkToro gives you several powerful ways to do this.
Let's look at how to use these search options.
You Don't Need a Buyer Persona. ...
This article from the SparkToro blog, 'You Don't Need a Buyer Persona...', provides excellent, practical examples of how to run these initial searches.
Read the section titled 'Step 1: Start with macro-to-micro research.' Focus on the two examples provided: Example 1: Searching by topic ('My audience frequently talks about: clean makeup'). Example 2: Searching by a known influencer ('My audience follows the social account: myfriendjanine'). Notice how both searches uncover a rich ecosystem of related social accounts, podcasts, and YouTube channels.
For your SaaS ventures, you could define your audience by searching for:
- Topics they discuss: "B2B sales automation," "developer productivity tools"
- Words in their profile: "SaaS founder," "VP of Marketing," "software engineer"
- Accounts they follow: A competitor, a major industry thought leader, or a niche news source.
- Websites they visit:
indiehackers.com,techcrunch.com, a specific subreddit.
The power here is in triangulation. Running several different searches will give you a multi-dimensional view of your audience's online behavior.
Step 2: Vetting Influencers with 'Hidden Gems' and SparkScore
Once you've run a search, SparkToro will present you with lists of social accounts, podcasts, and websites that your audience engages with, typically sorted by the percentage of your audience that follows them. The top results will often be huge, well-known accounts (like TechCrunch or Google). These are not micro-influencers and are hard to partner with.
This is where SparkToro's most powerful feature for our purpose comes into play: the "Hidden Gems" filter.
Audience Intelligence, on Steroids with Rand Fishkin
Let's return to the podcast transcript with Rand Fishkin to understand this critical feature.
Read the section that starts with 'Yeah. Now you got this something that you call “Hidden Gems.”' This section explains that the filter surfaces accounts with high engagement relative to their audience size—precisely the micro-influencers we are looking for.
Applying the "Hidden Gems" filter is the single most important action you can take in SparkToro to achieve this lesson's goal. It cuts through the noise and shows you the creators who have a strong, authentic connection with their audience. These are your ideal collaboration targets.
Quantifying Influence with SparkScore
Beyond finding hidden gems, you need to vet them. How can you tell if an account with 8,000 followers is more "influential" than one with 20,000? SparkToro provides a metric called SparkScore to help you do this.

The score provides a normalized way to compare the relative influence of different accounts.
Audience Intelligence, on Steroids with Rand Fishkin
Rand Fishkin explains the logic behind SparkScore in this final excerpt from the podcast.
Read the section that begins with 'For sure. You said that you look for high engagement relative to the audience size...'. This will clarify how SparkToro calculates engagement ratios and what SparkScore represents.
When vetting your list, a high SparkScore is a strong positive signal. It indicates that when this person speaks, their audience listens and engages.
Your Assignment: Build Your Micro-Influencer Target List
Now it's time to put this into practice. Your task is to use SparkToro to build a vetted list of 10-15 potential micro-influencers for a hypothetical SaaS idea.
- Sign Up: Go to SparkToro.com and create a free account. As mentioned in the podcast transcript, this will give you 10 free searches per month, which is more than enough for this assignment.
- Define Your SaaS: Pick a simple, hypothetical SaaS idea. For example: "A project management tool for freelance web developers" or "An AI-powered content scheduler for B2B marketers."
- Run Your Searches: Perform at least 3-4 different searches in SparkToro to define your target audience. Use a mix of the search types we discussed (talks about, follows, etc.).
- Find the Hidden Gems: For each search result, navigate to the
Social,Podcast, andYouTubetabs. Apply the "Hidden Gems" filter. - Analyze and Vet: Examine the filtered list. Look at the follower/subscriber counts, the SparkScore (for Twitter accounts), and the "% of Audience" metric. Click through to a few profiles to get a feel for their content and tone.
- Build Your List: Create a simple spreadsheet or document. For each of your 10-15 chosen micro-influencers, log the following information:
- Name: The influencer's name or handle.
- Main Platform: (e.g., Twitter, YouTube, Podcast).
- Follower/Subscriber Count:
- Profile Link:
- Reason for Inclusion: A brief note on why you believe they are a good fit (e.g., "High engagement on topic X," "Audience is a perfect match for our ICP," "Hosts a podcast our target audience listens to").
This hands-on exercise will turn theory into a practical skill, leaving you with a tangible asset you can use for future outreach campaigns.
Test your understanding!
You're looking for micro-influencers to promote your new SaaS that helps remote teams track their carbon footprint. You run a SparkToro search for "people who talk about: remote work". The top result is a famous business author with 2 million followers. The 15th result, after applying the "Hidden Gems" filter, is a newsletter author with 9,000 subscribers who writes weekly about sustainable business practices for distributed companies.
Who is the better target for an initial partnership, and why?
Show answer
The newsletter author with 9,000 subscribers is the far better target.
- Relevance: Their niche (sustainable business for distributed companies) is an exact match for your product's value proposition. The famous author's audience is likely far too broad.
- Reachability: As a startup, you are much more likely to get a positive response from a micro-influencer than from a major author who is inundated with requests.
- Trust: The newsletter author's audience trusts them specifically for advice on this topic, making their recommendation more potent. This is a perfect example of why the "Hidden Gems" filter is so powerful.
Conclusion
You now have a systematic process for finding high-potential partners who can amplify your message to a relevant and engaged audience. By focusing on audience intelligence first, you move beyond vanity metrics like follower counts and focus on what truly matters: a genuine connection with your ideal customers.
Key Takeaways:
- Micro-influencers drive high engagement due to their niche focus and authentic connection with their audience.
- SparkToro is an audience intelligence tool that helps you find sources of influence by starting with your target customer, not a list of celebrities.
- The "Hidden Gems" filter is your most important tool for identifying micro-influencers who have high engagement relative to their audience size.
- Vetting is crucial. Use metrics like SparkScore and a qualitative review of an influencer's content to build a high-quality, targeted list.
Preview of the Next Lesson:
While you're identifying others to talk about your product, it's equally important to build your own narrative. One of the most effective ways for a founder to build trust and an audience is by being transparent. In the next lesson, you will create a 7-day 'building-in-public' content calendar to document your SaaS journey on social media, turning your own progress into a powerful marketing asset.
