Help the user with acquiring first b2b customers using insights from 7 guests and posts across Lenny's Podcast and Newsletter.
Ben Williams: "They started with a really narrow, early focus. It was a single persona, single context, single use case, and what that meant for Snyk was developers building applications using Node.js who wanted to ensure that the open source dependencies they were pulling into their apps were secure."
Achieve early traction by solving a single problem for a narrow persona before expanding to the wider market.
Sri Batchu: "My view is you start off with founder-led sales, the early team needs to know how to actually sell. Then you hire your first couple of salespeople, then you start some very low cost targeted marketing efforts. So whether it's content, community, small scale events, and then PR, after all of that is when you start paid and brand effort and then SEO probably start around the same time that you start paid marketing efforts. The reason for the progression the way I've described it is the channels get more expensive as you go farther along and they get more effective as you understand more about your customers."
Master the sales process manually as a founder to build deep customer knowledge before attempting to scale or hire a sales team.
From "How today's fastest growing B2B businesses found their first ten customers": "In practice, it’s even easier — almost every B2B business BOTH hits up their personal network AND heads to the places their potential customers were spending time. The question isn’t which of these two routes to pursue, but instead how far your own network will take you before you move on."
Leverage personal networks first because they provide the baseline of trust necessary for a buyer to take a risk on an early-stage product.
From "How to find and win your first 10 B2B customers": "One of the recurring themes (and biggest surprises) across my interviews is the value, and effectiveness, of going cold outbound in the early stages—cold emails, cold DMs, cold calling. But you need to be clever about how you do this."
Use highly personalized and creative cold outreach targeted at specific strategic individuals rather than using automated or generic scripts.

Applicable for protocol discovery, collaborative protocol development, experiment tracking, lab protocol management, and scientific documentation.
Analyzes job descriptions and generates tailored resumes that highlight relevant experience, skills, and achievements to maximize interview chances
Generate Excalidraw diagrams from natural language descriptions. Use when asked to "create a diagram", "make a flowchart", "visualize a process", "draw a system architecture", "create a mind map", or "generate an Excalidraw file". Supports flowcharts, relationship diagrams, mind maps, and system architecture diagrams. Outputs .excalidraw JSON files that can be opened directly in Excalidraw.
Build and distribute Expo development clients locally or via TestFlight
Use when you have a written implementation plan to execute in a separate session with review checkpoints
Data structure for annotated matrices in single-cell analysis. Use when working with .h5ad files or integrating with the scverse ecosystem. This is the data format skill—for analysis workflows use scanpy; for probabilistic models use scvi-tools; for population-scale queries use cellxgene-census.
Benchling R&D platform integration. Access registry (DNA, proteins), inventory, ELN entries, workflows via API, build Benchling Apps, query Data Warehouse, for lab data management automation.
Comprehensive molecular biology toolkit. Use for sequence manipulation, file parsing (FASTA/GenBank/PDB), phylogenetics, and programmatic NCBI/PubMed access (Bio.Entrez). Best for batch processing, custom bioinformatics pipelines, BLAST automation. For quick lookups use gget; for multi-service integration use bioservices.
