A software development agency needs lead generation software that finds two kinds of buyer, founders who have money and no engineers, and managers at established companies whose software backlog has stopped moving, and then writes to each about the thing they are visibly short of. Expect to pay $12 to $150 a month for the tools. Because a custom project is a large sale that takes weeks to close, the software must keep a long thread going and record what each buyer said; a tool that only blasts first emails will lose to a referral every time.

Who buys custom software, and what they say out loud

Development agencies tend to have one of three buyers, and the three need different first lines.

  • The founder without a technical co-founder. They have raised money or have revenue and need a first version of the product. They answer a message about their specific product, written by someone who understood the idea.
  • The product or operations leader at a mid-sized company. They have a backlog of internal tools, customer portals or integrations that their own developers will not reach this year. They want capacity.
  • Another agency. A design or marketing agency that sells websites and apps but has no developers will resell your work. This is a partner, not a client, and it deserves its own short list.

The public clues differ for each. A founder announces a funding round or a launch. A mid-sized company posts the same "senior engineer" job for three months, which says the work exists and the hiring is not working. A third kind of clue is an old product: a website with a login page that looks ten years out of date. A person can see all three; the question is whether your software can.

Test the tool on your best past client

Before you pay anything, pick your most profitable project and write down what the client looked like six months before they hired you: their size, their title, what their site said, what job ads they had open. Then ask the software, or the sales rep, to find ten similar companies. If the ten look nothing like your client, the targeting is generic and a longer plan will not fix it. This test costs an hour and will save you a year of a bad subscription.

Requirements that matter for a development shop

  1. Filter by role and company size. "Founder or CEO at companies of 2 to 30 people" and "VP of product or operations at companies of 100 to 1,000" are two separate searches.
  2. Read the company's pages. A line about their job posting or their product launch has to come from somewhere real. If the tool can only insert a first name and a company name, you will read as one of two hundred identical messages in their inbox that week.
  3. Handle long gaps. A founder who says "we start building in January" should come back in December. A sequence that stops after three emails cannot do that.
  4. Keep a project note. Budget, timeline, stack and who decides belong beside the contact. Sales cycles for custom work are measured in weeks, and the details get lost fast.
  5. Let a reply stop everything. A founder who answers "can you call Tuesday" should not get a follow-up from software on Wednesday.

What the pieces cost, as published on October 30, 2026

Hunter listed Starter at $49 a month ($34 billed yearly) for 2,000 credits, and Lusha listed Starter at $49.90 a month ($37.45 annual) for 400 credits. UpLead's Essentials was $99 a month ($74 annual) for 170 credits. On the sending side, Instantly's Growth plan was $47 a month ($37.60 yearly) for 5,000 emails and 1,000 uploaded contacts, and Smartlead's Base plan was $39 ($32 annual) for 2,000 active leads and 6,000 emails. Each of these does one job. Plan on one tool to find people, one to send, and a place to keep notes, then check whether a single product covers all three before you buy three.

Do not hire an outside lead generation service for development work without reading the messages it will send in your name. A message that describes your agency wrongly costs you a founder you would have won. If a software startup is the buyer you want, lead generation software for SaaS startups covers the other side of that table, and how to get clients for an IT company covers the managed-services buyer.

A rule that affects every email you send

The Federal Trade Commission's CAN-SPAM guide applies to business email as well as consumer email. Your message needs a valid physical postal address, a working opt-out that you honor within 10 business days, and a subject line that matches the content. Civil penalties are up to $53,088 for each message that breaks the rules. Buyers also notice who writes carefully; for the writing side, see cold email templates for software development agencies.

A worked example

Say Tern Works, a six-developer shop in Austin, builds web apps and mobile apps for funded startups. The owner, Imani, wants three new projects a quarter. Her average project is $45,000. Her stack costs $120 a month, or $1,440 a year, which is about three percent of one project.

She writes a target: "Founders and heads of product at seed to Series A software startups in the US with 3 to 25 people that have posted an engineering role in the last 60 days." That gives her 90 people. Her first message: "Hi Dana, I saw the open full-stack role on your careers page and your note that the scheduling product launches in the spring. If hiring is slow, we build the first production version in about 12 weeks for a fixed scope. Could I send two projects like yours we shipped? Imani, Tern Works, 1700 Guadalupe St, Austin, imani@ternworks.example.com. Reply "stop" and I won't write again."

She sends 8 a day, follows up on day 5 with a short case summary and on day 14 with a question about their timeline. Founders who say "not yet" get a note scheduled for the month they named. After a quarter she keeps three numbers: contacts written, replies, and calls booked. If calls booked is below four from 90 people, she changes the target and leaves the sending volume alone.

When Imani is the only person who does outreach, Rocketship can take on the repetitive half of it: tell it who you want, and it reads each company's site, finds the person, emails from your Gmail, follows up and books the call on your calendar. It does not scope a project, estimate hours or join the discovery call, and it does not send from Outlook or send LinkedIn messages. Ninety new people is about 360 credits, so Launch ($24.99 a month, 500 credits, up to 70 emails a day) covers her; the pricing page shows the others and the 7-day trial takes a card.
