👋 Welcome to today’s edition of Build & lead (formerly the CTO blueprint), a newsletter by Appolica. Every two weeks, we dive deep into the tech, product, and leadership challenges that keep founders up at night.

In this week’s issue, we talk about how to choose an outsourcing agency to build your software product, covering what to look for and common pitfalls to avoid. Then, we guide you through migrating your app from Native to Flutter, and share strategies to effectively restructure your tech team during periods of rapid growth.

Outsourcing has become the go-to strategy for early-stage startups aiming to build software quickly. But with many options available - fixed-price MVPs, dedicated teams, or hiring individual developers, how do you choose the right model to meet your needs?

In this article, I’ll break down the main outsourcing models, what to look for when choosing an agency, and why it’s critical to understand the specific needs of early-stage startups.

As companies look to streamline app development, many are migrating their native mobile apps to cross-platform frameworks like Flutter. This shift offers several advantages: faster development cycles, lower maintenance costs, and a unified experience across both Android and iOS.

However, migrating a complex, production-ready app presents challenges that require a solid strategy to avoid impacting the ongoing development of a product. In this article, I’ll compare two common migration strategies — the Big Bang approach and incremental migration—and break down the pros and cons of each approach and explain why an incremental, flow-based migration may often be the smarter choice.

Growth comes quickly with early-stage startups. And as your startup gains traction, your lean engineering team can quickly become overstretched. Whether you're moving from pre-seed to seed or scaling to Series A, restructuring your tech team is essential. At a growth pace, new demands arise quickly and without the right structure, your team can become inefficient and lose focus.

In this post, I’ll explore how to structure your engineering team at the different stages of growth to ensure optimal speed, autonomy, and delivery efficiency. We’ll dive into the benefits of splitting teams effectively, why cross-functional squads are powerful, and what lessons we can learn from companies like Shopify, Netflix, and Uber.

Claude 3.5 Sonnet & Haiku: Anthropic has launched the upgraded Claude 3.5 Sonnet, with enhanced coding performance, and introduced Claude 3.5 Haiku, matching its predecessor’s performance at the same cost. In a public beta, Claude 3.5 Sonnet now offers computer use, enabling the model to interact with computers like a human.
IBM’s Granite 3.0: IBM has launched its Granite 3.0 AI models, including 8B and 2B variants, optimized for business use. These models offer strong performance, low-latency inference, and advanced safety features. Granite will power IBM’s watsonx Code Assistant.
Meta’s FAIR AI release: Meta’s Fundamental AI Research (FAIR) team has unveiled eight new AI models, datasets, and tools, pushing innovation across AI disciplines. Leading the release is Segment Anything Model 2.1 (SAM 2.1), featuring improved object tracking and differentiation for image and video segmentation. Additionally, Meta introduced Spirit LM, an open-source model integrating speech and text, and Layer Skip, a solution to speed up large language model generation without specialized hardware.
Microsoft’s autonomous AI agents: Microsoft will soon allow organizations to create custom AI agents within Copilot Studio. The company is also launching 10 new autonomous agents to enhance operations in sales, service, finance, and supply chain teams.
xAI’s API launch: Elon Musk’s AI startup, xAI, has launched its Grok API, featuring the “grok-beta” generative AI model. Priced at $5 per million input tokens and $15 per million output tokens, the API supports limited functionality, with references to Grok 2 and Grok mini models.
